1 Introduction Chapter 1, “Introduction”, describes the operational features of the Conext XW+ Inverter/Charger.
Introduction Features The Conext XW+ is a modular building block sine-wave inverter/charger that can be used for residential and commercial battery based off-grid, grid backup, and grid interactive applications. The Conext XW+ is a self-contained DC to AC inverter, battery charger, and integrated AC transfer switch. It is configurable in a hybrid system to operate with generators and renewable energy sources. These configurations are capable of extending battery based off-grid/backup autonomy.
Operation Available Conext XW+ Accessories Accessory Part Number Conext XW+ Power Distribution Panel 865-1015-01 Conext XW+ Power Distribution Panel (Without AC Breakers) 865-1014-01 Conext XW+ Conduit Box 865-1025-01 Conext XW+ Connection Kit for INV2 INV3 PDP 865-1020-02 Conext System Control Panel 865-1050-01 Conext Automatic Generator Start 865-1060-01 Conext MPPT 60 150 Solar Charge Controller 865-1030-1 Conext MPPT 80 600 Solar Charge Controller 865-1032 Conext ComBox 865-1058 Con
Introduction The Conext XW+ has an internal automatic transfer switch (K1, K2) which allows either AC1 or AC2 to be connected to the inverter input, but not both at the same time (See Figure 1-1, “Connection Points and Major Power Conversion Components of Conext XW+ ” on page 1–4). This allows shared AC energy during charging or to directly pass through from AC1, or AC2, to AC Out.

Operation Surge Performance Unlike many other inverters, the Conext XW+ helps stop voltage from sagging dramatically during surge conditions. The Conext XW+ handles surges of over twice its rated output power with only a minimal drop in output voltage for limited periods of time. Islanding Protection Islanding protection is an essential safety feature that helps reduce harm to those working on the utility grid from a distributed energy source such as the Conext XW+.
Introduction AC Coupling Off-grid AC Coupled system architecture is often used to create a stand-alone grid. Commonly this means that PV inverters are connected to the output of a battery-based inverter/charger putting both on the same AC bus along with the AC loads. In this scenario, the battery powered inverter charger provides the necessary frequency and voltage to enable the PV inverter to produce power.
Operation Further details about AC Coupling can be found in the document AC Coupling of Inverters Solutions Guide (975-0240-01-01) available at solar.schneider-electric.com. Multi-unit Operation Up to three Conext XW+ units can be installed together in a single phase configuration with the Conext PDP (Power Distribution Panel). A maximum of four Conext XW+ units can be installed together in a single phase configuration with the addition of a second PDP.
Introduction AC Transfer Multiple Conext XW+ units monitor each other to determine the quality of AC input. If AC input is deemed to be bad by any of the paralleled units, no transfer to AC Out occurs and the AC LED continues to flash on each unit’s information panel until the AC is qualified by all. If the system was in pass-through and AC fails on any unit, all units transfer to invert simultaneously. Faults When the Conext XW+ detects a fault condition, the fault is displayed on the Conext XW+.
Monitoring the Conext XW+ Monitoring the Conext XW+ Operation of the Conext XW+ can be monitored using the factory-installed inverter information panel or the optional Conext System Control Panel and ComBox. To configure the Conext XW+, the Conext System Control Panel or ComBox must be used. Conext XW+ Information Panel The Conext XW+ information panel features: • Buttons for Conext XW+ Startup/Shutdown/Standby control, clearing faults and warnings, and battery equalization.
Introduction Conext System Control Panel The Conext System Control Panel (Conext SCP) or Conext ComBox is required for configuring the Conext XW+ and other Xanbus-enabled system components. The Conext SCP features: • A liquid crystal display which provides graphics and text describing real time operation and status information. • LED event and warning indicator. • Internal clock which is used to control time-dependent Conext XW+ functions.
2 Monitoring Operation Chapter 2, “Monitoring Operation”, contains information about monitoring Conext XW+ Inverter/Charger operation using the inverter information panel or the Conext System Control Panel.
Monitoring Operation Monitoring Operation with the Inverter Information Panel The inverter information panel on each Conext XW+ monitors a single Conext XW+. The Conext XW+ information panel displays basic information and performs start up, shut down, equalization and standby functions. LEDs on the information panel indicate AC input status, Conext XW+ status, battery condition, and charging and equalization status.
Monitoring Operation with the Inverter Information Panel When one AC input LED is on and the other AC input LED is flashing, AC input is present on both AC1 and AC2. However, the Conext XW+ can qualify and receive AC input from only one source at a time. The qualified source is represented by the steadily lit LED. When two sources of AC input are present, the Conext XW+ uses the source selected under AC Priority in the AC Settings menu.
Monitoring Operation Monitoring Charger Status The green LED labelled “A” indicates the Conext XW+ is charging the battery bank. When this LED is on, the numeric display screen shows battery charging current in amps. Symbol LED On LED Flashing LED Off The Conext XW+ is charging the battery bank. The numeric display screen shows battery charging current in amps. AC coupled charging is occurringa. The Conext XW+ is not in charge mode.
Monitoring Operation with the Inverter Information Panel Symbol LED On LED Flashing The Conext XW+ has a fault and has stopped charging or inverting. The LED also turns on steadily if the unit has both a fault and a warning. The Conext XW+ has a warning. A warning may escalate to a fault if the warning condition does not go away. Equalizing Batteries Button Pressing the Equalize button ( symbol) for five seconds initiates a battery equalization cycle.
Monitoring Operation WARNING BATTERY TYPE AND SETUP HAZARDS Incorrect battery configurations or settings for battery types can lead to dangerously high battery temperature, fire and explosion. To avoid damaging your batteries during charging or equalization, and to minimize the risk of fire or explosion consult battery manufacturer's documentation before setting battery parameters and follow the battery manufacturer's recommended settings. • Always use and connect the Battery Temperature Sensor (BTS).
Monitoring Operation with the Inverter Information Panel Using Startup/Shutdown/Standby Modes Startup/Shutdown control When the Conext XW+ is operating, pressing and holding the STARTUP/SHUTDOWN button for five seconds shuts down the unit. To return the unit to its previous operating state, press the STARTUP/SHUTDOWN button again. While the Conext XW+ is turning off, the other inverter information panel buttons stop working. The shutdown process cannot be cancelled.
Monitoring Operation In a multiple-unit installation, when a slave Conext XW+ is shut down, other Conext XW+ units continue to supply Xanbus network power and the Conext AGS and Conext SCP continue to operate. Monitoring Battery Level When the Conext XW+ is inverting, the row of five LEDs indicates the approximate available SOC (State of Charge) of the batteries connected to the system. This capacity reading is based on battery voltage.

Configuration Inverter Settings Menu The Inverter Settings menu contains settings that control when the Conext XW+ starts and stops producing AC output. Table 3-2 Inverter Settings Menu Item Description Low Batt Cut Out Low Batt Cut Out controls when the inverter stops producing AC output due to a low battery voltage condition. The inverter will stop producing AC output only after this level has been reached for the period of time set by the LBCO Delay. This setting is not temperature compensated.
Inverter Settings Menu Using the Low Battery Cut Out and LBCO Delay Settings WARNING ADVANCED CONFIGURATION HAZARD Advanced menu settings should be used by qualified personnel only. Three phase operation should be configured by qualified personnel only. Consult with the local utility before enabling Conext XW+ sell mode or grid support functions. Do not change these settings unless you are under the supervision and direction of qualified personnel.
Configuration Single units When a single Conext XW+ has search mode enabled, the inverter sends electrical search pulses through its AC output. These search pulses look for connected AC loads. The delay between search pulses is set using the Search Delay setting. After a load larger than the Search Watts setting is detected, the inverter starts producing AC output.
Charger Settings Menu Charger Settings Menu The Charger Settings menu provides options for configuring the Conext XW+ to operate from your battery bank. Table 3-3 Charger Settings Menu Item Description Batt Type Sets the system battery chemistry and type: Flooded (default), AGM, Gel, LithiumIon, and Custom. Selecting Custom displays the Custom Settings item, which allows you to adjust the settings for each charging stage.
Configuration Table 3-3 Charger Settings Menu Item Description Chg Block Stop Sets the time that charging on AC1 can resume. At the Chg Block Stop time, charging on AC1 is enabled again. For default settings, see “Charger Settings Menu” on page B–3. Battery Charger Functions When AC power is available, the Conext XW+ can operate as a battery charger. Different battery types and chemistries require different charging voltage levels.
Charger Settings Menu Bulk Stage Battery Voltage Absorption Stage Float Stage (Boost Stage) Absorption Voltage 3-Stage Charge Float Voltage Custom Charge Boost Timer 1hr fixed Time Max Absorb Time - Default 3 hrs (adjustable 1 min - 8 hrs) Battery Current Max Charge Rate Absorption Exit Current Threshold = 2% of programmed AH capacity Time Figure 3-4 Three-Stage Battery Charging Cycle 975-0240-01-01 3–13
Configuration Notes: When the charge cycle is interrupted, the charger will restart charging at the beginning of the multi-stage algorithm. Exit Current Threshold can be effectively disabled by programming the amp-hour capacity to 0. In this case, absorption will only exit once the Max Absorption timer expires. Charge current during equalize state (optional state not shown here) is normally limited to 10% of the programmed amp-hour capacity setting.
Charger Settings Menu Note: If there are DC loads on the batteries, the charger’s current may not decrease to a level to transition to the next stage of charging. In this case, the charger stays in absorption until the Absorb Time setting is reached. To avoid having the charger remain in absorption for too long, adjust Absorb Time on the Charger Settings menu.
Configuration Float Stage Float charge maintains the batteries slightly above the self discharge voltage of the batteries. The charge current in float is the current necessary to maintain the batteries at the Float Voltage setting, limited only by the inverter's capability or other settings that limit the inverter's maximum charge rate. Float charging reduces battery gassing, minimizes watering requirements (for flooded batteries), and helps the batteries remain in a constant state of readiness.

Configuration Note: When the charge cycle is interrupted, the charger will restart charging at the beginning of the multi-stage algorithm. Exit Current Threshold can be effectively disabled by programming the amp-hour capacity to 0. In this case, absorption will only exit once the Max Absorption timer expires. Charge current during equalize state (optional state not shown in graph) is normally limited to 10% of the programmed amp-hour capacity setting.
Charger Settings Menu After absorption, the maximum charge DC current is set to 10% of battery capacity (for example, 44 A for 440 Ah). See Figure 3-6. This constant current charge will continue until the voltage has increased to the equalize voltage at which point the battery will be regulated at the temperature compensated equalize voltage.
Configuration If the Conext XW+ will not perform the equalization, see Warning W96 “Cannot Equalize” in Table 4-3 on page 4–12. WARNING EQUALIZATION HAZARD Only flooded lead acid batteries should be equalize charged. Hydrogen and oxygen gases are produced when batteries are equalized and can potentially cause an explosion if ignited. Corrosive battery acid can escape. Provide adequate ventilation and remove all sources of ignition, such as open flames, sparks, electric motors, relays, light switches, etc.
Charger Settings Menu Further details about Lithium Ion support can be found in the document “Lithium Ion Application Note (Document Number: 976-0319-01-01)” available at solar.schneider-electric.com. WARNING ADVANCED CONFIGURATION HAZARD Advanced menu settings should be used by qualified personnel only. Three phase operation should be configured by qualified personnel only. Consult with the local utility before enabling Conext XW+ sell mode or grid support functions.
Configuration Table 3-4 Custom Battery Settings Menu Item Description Batt Temp Comp Battery temperature compensation for a custom battery type. This setting is the reference that the BTS uses to adjust the charging voltage when the temperature is above or below 25 °C (77 °F).
AC Input Settings AC Input Settings WARNING ADVANCED CONFIGURATION HAZARD Advanced menu settings should be used by qualified personnel only. Three phase operation should be configured by qualified personnel only. Consult with the local utility before enabling Conext XW+ sell mode or grid support functions. Do not change these settings unless you are under the supervision and direction of qualified personnel. Failure to follow these instructions can result in death or serious injury.
Configuration Table 3-5 AC Settings Menu Item Description AC1 Breaker Sets the AC1 (Grid) breaker size, based on the size of the breaker installed upstream from the AC1 connection port. The installed breaker size must not exceed the capacity of the upstream distribution panel. The Conext XW+ limits the maximum current draw on AC1 by derating its charging current to an equivalent of 80% of the AC1 breaker setting.
Grid Support Settings Grid Support Settings The Grid Support Settings menu contains configuration options for grid-tie operation. To enable these settings, Grid Support must be enabled in the Setup menu (see “Conext XW+ Setup Menu” on page 3–2). In grid support mode, the Conext XW+ supports the utility grid by limiting the power drawn from the utility to close to zero. This mode is desirable for using excess energy from auxiliary DC sources like PV, while still maintaining a charged battery bank.
Configuration Table 3-6 Grid Support Settings Menu Item Description Grid Supp Volts Sets the level to which the batteries will be discharged when the inverter is selling power to the grid or supporting the power grid by providing additional power to the loads on AC Out. This setting is not adjusted for the battery temperature even if the temperature sensor is installed. Sell Turns sell mode on and off.
Grid Support Settings Table 3-6 Grid Support Settings Menu Item Description Load Shave Amps Sets the maximum amount of current that can be drawn from the AC1 (grid) input by the loads and battery charger combined. This setting determines the amperage level at which the inverter starts drawing power from the batteries to add to the utility power to meet the demand of the loads.
Configuration Prioritizing and Managing Energy Sources with Advanced Features The Conext XW+ can be programmed to control how and when to use utility power as well as external DC sources of energy such as batteries and solar charge controllers. Advanced features allow management of peak loads, time-ofuse billing and self consumption. Grid Support WARNING ADVANCED CONFIGURATION HAZARD Advanced menu settings should be used by qualified personnel only.
Prioritizing and Managing Energy Sources with Advanced Features excess power from the external DC sources is not converted and hence not used. For optimal sell performance, a battery bank of minimum 440 Ah is recommended. Grid Support enabled, Sell enabled In this mode, all available excess DC power is first used to power local AC loads attached to the inverter output. Any remaining power (up to the Max Sell Amps setting) is exported to the utility grid (AC1).
Configuration not reach bulk/absorption voltages in this mode, it is recommended to occasionally force a full charge cycle by either temporarily disabling grid support or forcing a bulk charge cycle from the grid (see “Force Chg” on the“Conext XW+ Setup Menu” on page 3–2.) Enhanced Grid Support with Conext MPPT Solar Charge Controllers This setup is suitable for Conext Systems with only Conext MPPT Solar Charge Controller(s) networked to Conext XW+ units through Xanbus.
Prioritizing and Managing Energy Sources with Advanced Features Note: [Tdelay] is an entry/exit transition time delay to/from grid support and sell mode. If the battery voltage has higher fluctuations due to DC renewable sources (e.g. charge controllers, wind turbines, and so on), then the time delay can be increased by setting Sell Dly 40s to enabled (Table 3-12, “Advanced Features Menu” on page 3–49).
Configuration Peak Load Shaving (PLS) Many utilities impose a surcharge on their customers based on the peak load used by a facility. To reduce utility peak demand charges, the inverter can be configured (using the Load Shave Amps setting) to limit the maximum draw the AC loads place on the utility. The inverter can be programmed to provide power above a specified level to avoid the surcharge.
Prioritizing and Managing Energy Sources with Advanced Features When using the system for time-of-use metering, the system should be designed with a battery capacity large enough to support loads during the entire peak rate period without reaching the Low Batt Cut Out setting. Note: If the batteries reach the Low Battery Cut Out setting, the Conext XW+ automatically reconnects to the utility grid to maintain the connected load.
Configuration Generator Support Settings WARNING ADVANCED CONFIGURATION HAZARD Advanced menu settings should be used by qualified personnel only. Three phase operation should be configured by qualified personnel only. Consult with the local utility before enabling Conext XW+ sell mode or grid support functions. Do not change these settings unless you are under the supervision and direction of qualified personnel. Failure to follow these instructions can result in death or serious injury.

4 Troubleshooting Chapter 4, “Troubleshooting”, contains information and procedures for identifying and solving possible problems with the Conext XW+ Inverter/Charger.
Troubleshooting General Troubleshooting Guidelines This section will help you narrow down the source of any problem you may encounter. Please read the following troubleshooting steps: 1. Check for a Warning or Fault message on the Conext System Control Panel or a Fault code on the inverter information panel. If a message is displayed, record it immediately. 2. As soon as possible, create a detailed record of the conditions at the time the problem occurred.
Inverter Applications Inverter Applications The Conext XW+ performs differently depending on the AC loads connected to it. If you are having problems with any of your loads, read this section. Resistive Loads Resistive loads are the easiest and most efficient to drive. Voltage and current are in phase, which means they are in step with one another. Resistive loads generate heat in order to accomplish their tasks. Toasters, coffee pots, and incandescent lights are typical resistive loads.
Troubleshooting Clocks You may notice that your clocks are not accurate. Some of the clocks on your appliances may reset when the Conext XW+ is in search mode. Disabling search mode will resolve this issue (See “Using Search Mode” on page 3–9). Searching When the inverter is in search mode, it may fail to start some loads even though the rated wattage on the load is more than the Search Watts setting. Disable search or apply an additional load (companion load) to make the inverter exit search mode.
Inverter Troubleshooting Problem Possible cause Solution(s) No AC power output. Open AC output breakers or fuses and bad output wire connections. Check the Load AC Voltage status on the SCP Meters screen and check AC voltage on the inverter AC Out terminal block. The inverter information panel displays . Inverter is disabled. Re-enable inverter.
Troubleshooting Problem Possible cause Solution(s) Inverter goes into invert mode and starts producing AC output and then stops or does not start at all. Search Watts setting is too low or high. Potential problem loads for search mode: If the search sensitivity is set higher than the combined loads, then connect an auxiliary load to bring the inverter out of search mode before the appliances can be turned on.
Battery Charger Troubleshooting Battery Charger Troubleshooting To determine the cause of a charger error condition, refer to the troubleshooting solutions below to resolve the situation. Problem Possible Cause Solution AC1/AC2 LED is on, but will not start charging (allow 40 seconds to synchronize). 1) Charger is disabled on the Setup menu. 1) Enable the charger. 2) Charger Block is enabled and the Conext XW+ is inside of the charger block time window.
Troubleshooting Problem Possible Cause AC1 or AC2 LED is flashing, but will not start charging AC voltage and frequency at the AC input terminal are within nominal range, but the inverter output is not yet synchronized to the AC source. There are four possible causes: (allow 40 seconds to synchronize). 4–8 Solution 1) The inverter may already be synchronized to another AC source. 1) The inverter is operating normally.
Battery Charger Troubleshooting Problem Possible Cause Solution Charger amperage drops off before full charging has finished (no Fault LED). AC frequency at the AC input terminal may be out-of-tolerance (too high or low) or the AC voltage may be outside the Hi AC Volt or Lo AC Volt settings. AC input voltage approaching the low disconnect level. Check the settings on the AC Settings menu. Check for the correct AC voltage or frequency at the AC input terminal.
Troubleshooting Problem Possible Cause Solution Charger output is low. Loose or corroded battery connections. Check and clean all connections. Loose AC input connections. Check and tighten AC wiring connections. Worn out batteries. Replace batteries. Battery cables too small or too long. Refer to cable and battery recommendations in the Conext XW+ Installation Guide. If a BTS (Battery Temperature Sensor) is installed, it may be in a cold area or have fallen off the batteries. Inspect the BTS.
Faults and Warnings Warning Messages Warning messages appear on the Conext SCP to alert you to an impending system change. You can view the 20 most recent warning messages using the Conext SCP’s warning log, accessible from the View Device Info menu. Each warning has a time stamp to let you know the date and time that the warning appeared. If several warning messages occur before you can acknowledge or clear them, they are displayed together on a warning list.
