An optional interface is available which will allow Solar Boost 2000 to operate as a power unit slave to a Battery Manager model 6210. When used with a 6210 controller, Solar Boost 2000 assumes the sophisticated three stage temperature compensated charge regimen matched to battery size and type provided by the 6210. Up to five Solar Boost 2000's may be operated from a single 6210 controller. The 6210 interface is available at the time of purchase, or can be added at a later date. The charge current increase you can expect is variable.
Current increase varies with PV temperature and battery voltage.
Lower PV temperature increases available power, while lower battery voltage increases current for a particular input power level. What you can be sure of is that Solar Boost 2000 will deliver the highest charge current possible for a given set of operating conditions. When conditions are such that extra power is not available from the PV array, Solar Boost 2000 will operate as a high performance series pass PWM controller. Charge current increase field test results obtained using four 75 watt PV panels in southern California are shown in the table below. Your performance may vary due to a variety of factors.
