1. Important Safety Information Before using the Inverter read and save the safety instructions. All wiring must follow the National Electric Code, The Canadian Electrical Code Part 1, Provincial or other codes in effect at the time of installation, regardless of suggestions in this manual. All wires should be copper conductors. This manual contains important instructions for Models 8KW & 12KW To be followed during installation and maintenance of the inverter.
1.2 Precautions When Working with Batteries 1-2-1. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flood eye with running cold water and seek medical attention immediately. 1-2-2. Never smoke or allow a spark or flame in the vicinity of a battery or engine. 1-2-3. Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery may cause an explosion. 1-2-4.

Don’t parallel the AC output of the inverters to increase power capacity as they do not have stacking functionality. 2.5.2 AC Charger The Global LF Series is equipped with an active PFC (Power Factor Corrected) multistage battery charger. The PFC feature is used to control the amount of power used to charge the batteries and to obtain a power factor as close as possible to 1.

De-sulphation The de-sulphation cycle, switch position 8, is marked in red because this is a very dangerous setting if you do not know what you are doing.
Charging depleted batteries The Global LF series inverter allows start up and through power with depleted batteries. For 12VDC models: after the battery voltage goes below 10V and the power switch is kept in the "ON" position and the inverter stays connected to the battery and the battery voltage doesn’t drop below 9V, the inverter will be able to charge the battery once qualified AC inputs are present.
2.5.4 Manual Frequency Switch All of our Global LF inverters have a 50/60 Hz selector switch. When the inverter is turned off and shore power is not present, the frequency of the inverter may be selected to be 50 or 60 Hz. 2.5.5 Power Saver There are 2 different working statuses for our Global LF inverter: “Power On” and “Power Off”. When the power switch is in “Unit Off” position, the inverter is powered off.
PICOGLF6024120ULC PICOGLF6024240SULC 90W 90W 25W 25W When in the search sense mode, the green power LED will blink, and the inverter will make a ticking sound. At full output voltage, the green power LED will light steadily, and the inverter will make a steady humming sound. When the inverter is used as an “uninterruptible” power supply the search sense mode or “Power Saver On” function should be defeated. Exceptions Some devices when scanned by the load sensor cannot be detected.
2.5.6 Protections The Global LF series inverter is equipped with extensive protections against various harsh situations/faults. These protections include: AC Input over voltage protection/AC Input low voltage protection Low battery alarm/High battery alarm Over temperature protection/Over load protection Short Circuit protection (1s after fault) Back feeding protection When over temperature / over load occur, after the fault is cleared, the master switch has to be reset to restart the inverter.

Greeting message of “Welcome to AIMS POWER” AC Status & Input Voltage “AC: abnormal” is displayed when AC input is not qualified. Output Voltage/Frequency and Output Current (in percentage) in Inverter mode Battery voltage Note: When the inverter is in Battery Priority mode, finishes a complete charging cycle and switches to inverter mode “AC: abnormal” will be displayed. In AC mode, the LCD will not display the status of the AC load. 2.5.
Allow at least 12 inches of clearance around the inverter for air flow. Make sure that the air can circulate freely around the unit. Fan noise level <60db at a distance of 1m 2.5.11 DIP Switches On the DC end of inverter, there are 5 DIP switches which enable users to customize the performance of the device.
load every 3 seconds. Each pulse lasts for 250ms. The inverter will remain in standby mode until a load has been detected. Then it will wake up from standby mode and start to invert electricity from the battery bank to supply the load. As this function is under Battery Priority, the inverter will always prefer to invert electricity from battery first even there is a qualified AC input present.
When the battery voltage is over 40℃ (104℉), it will reduce the charging voltage by 0.1Vdc with every degree of temperature rise. AIMS recommends that you install Battery Temperature Sensors on all banks to protect your batteries and to provide optimal charging of each bank. The battery temperature sensor mounts on the side of a battery.
3. Installation * All wiring must follow the National Electric Code, installation shall be in accordance with the Canadian Electrical Code Part 1 3.1 Location Follow all the local regulations to install the inverter. Please install the equipment in a location of dry, clean, cool temp with good ventilation.
3.3 AC Wiring We recommend using 10 to 8 AWG wire to connect to the ac terminal block. When in AC mode the AC input power will supply both the loads and AC charger, a thicker wire gauge for AC Input is required. Consult a qualified electrician about the specific wire gauge required in terms of wire material and inverter power. There are 3 different ways of connecting to the terminal block depending on the model.
Wiring Option 3 120Vac split phase Input: Hot line+ Hot line +Ground Output: Hot line +Neutral+Ground Remark: In such cases, each output hot line can only carry a half the rated capacity Max.
Caution: Wiring Option 2 and 3 are only allowed for split phase models (last letter of part # “S”). Wire all the other models according to Wiring Option 1. WARNING For split phase models, AC input neutral is not required in wiring. Never Connect Input Neutral to Output Neutral. Damage will result which is not covered under warranty. Always switch on the inverter before plugging in any appliance.

3.6 Mounting the Inverter In order to mount the inverter securely, the surface and the mounting hardware must also be able to support at least twice the weight of the inverter. To meet regulatory safety requirements, the PICOGLF Series must be mounted: Figure 22 1: On a horizontal surface (shelf or table top) with top side up, Figure 23 2: On a vertical surface (like a wall) with the DC terminals facing left and the fan axis horizontal.
4. Troubleshooting Guide Troubleshooting contains information about how to troubleshoot possible error conditions while using the Global LF Inverter & Charger. The following chart is designed to help you quickly pinpoint the most common inverter failures.
Symptom Inverter will not turn on during initial power up. Possible Cause Batteries are not connected, loose battery-side connections. Low battery voltage. No AC output voltage and no indicator lights ON. AC output voltage is low and the inverter turns loads OFF in a short time. Charger is inoperative, and unit will not accept AC. Charger is supplying a lower charge rate. Inverter has been manually transitioned to OFF mode. Charge the battery.
