Installation and Operation Manual IMPORTANT SAFETY INSTRUCTIONS 1. Refer servicing to qualified service personnel. Incorrect installation may result in risk of electric shock or fire. No user serviceable parts in this unit. 2. Remove all sources of power, photovoltaic and battery before servicing or installing. 3. WARNING - RISK OF EXPLOSIVE GASES a) Working in the vicinity of lead-acid batteries is dangerous. Batteries produce explosive gasses during normal battery operation.
RV Power Products - Solar Boost 2000 PRODUCT DESCRIPTION Solar Boost 2000™ is a 20 amp fully automatic, very high performance Maximum Power Point Tracking (MPPT) photovoltaic (PV) charge controller. Through the use of advanced patent pending MPPT technology, Solar Boost 2000 can increase charge current up to 30% or more. A high accuracy digital display is also provided to monitor PV charge performance. The controller is fully protected against voltage transients, reverse polarity, and overload conditions.
Installation and Operation Manual Battery Voltage displays battery voltage as measured at the Solar Boost 2000 battery terminals. The battery voltage measurement system is highly accurate. However, when high charge current is delivered to the battery, the displayed voltage will be somewhat higher than actual battery terminal voltage. This is due to voltage drop in the wires between the Solar Boost 2000 and battery.
RV Power Products - Solar Boost 2000 Because output power is constant while MPPT is operating, anything that leads to lower battery voltage will produce an increase in Output Charge Current. While a discharged battery is one way to produce lower output voltage, and therefore higher output current, other normal conditions may produce lower voltage as well. Any 12 volt power consumption during the day will decrease net battery charge current, which decreases battery voltage.
Installation and Operation Manual which is now being delivered at 12 volts would produce a charge current of 6.25 amps. A charge current increase of 1.8 amps or 40% is achieved by converting the 22 watts that would have been wasted into useable charge current. Note that this example assumes 100% efficiency to illustrate the principal of operation. In actual operation, boost will be somewhat less as some available power is lost in wiring, connections, fuse and in Solar Boost 2000.
RV Power Products - Solar Boost 2000 CHARGE OPERATION WITH 6210 CONTROLLER With Solar Boost 2000 integrated into a 6210 system, charge will begin whenever AC power, solar power or both are available. Refer to the 6210 operators manual for a complete description of it’s sophisticated three stage charge regimen.
Installation and Operation Manual Factory default setup criteria: • • • • Liquid electrolyte lead-acid battery Standalone operation (i.e. no optional 6210 controller) No temperature compensation (i.e. no optional SensorLug battery temperature sensor) Difference between PV open circuit voltage and maximum power voltage is 4.4V (VOC-VMP = 4.4V) FACTORY DEFAULT SETUP SWITCH 1 OFF SWITCH SWITCH SWITCH 2 3 4 OFF ON ON BATTERY VOLTAGE SETPOINT 14.
RV Power Products - Solar Boost 2000 MAXIMUM POWER VOLTAGE The nominal setting for this adjustment is the difference between the PV panel’s open circuit voltage (VOC) and maximum power voltage (VMP). These voltage values are typically listed on both the PV panel datasheet and on the rating label affixed to each PV panel. This value needs to be set correctly for the MPPT system to deliver maximum current boost. The factory setting is 4.
Installation and Operation Manual SOLAR BOOST 2000 SETUP ADJUSTMENTS AND FIELD CONNECTIONS FIGURE 3 The front panel serves as a heat sink for power control devices and requires free air circulation for cooling. Do not enclose the front panel behind a tight fitting door or otherwise substantially restrict air flow. SYSTEM WIRING Wiring requirements for Solar Boost 2000 are different than traditional PV controllers.
RV Power Products - Solar Boost 2000 A desirable installation would produce a total system wiring voltage drop of 0.6 volts or less, which can be achieved using the wiring method shown in Figure 4 and wire sizes shown in Table 3. The wire lengths shown in Table 3 will provide a maximum voltage drop of 0.42 volts (4% of 14 volts), with the remainder of the 0.6 volts consumed by connections fuse and so on. Note that lengths in Table 3 are shown for PV short circuit current values of 10 amps and 20 amps.
