DuoRacer Series Dual battery MPPT solar controller Overview DuoRacer series is perfect for off-grid solar system such as motorhome, RVs, campers, boats, and so on. It charges the main battery (BATT1)for living, and supports trickle charging(max. 1A) to the start battery(BATT2) of vehicles at the same time. Features • Maximum Power Point Tracking technology with ultra-fast tracking speed and the tracking efficiency is no less than 99.5% • Advanced MPPT control algorithm to minimize the MPPlost rate and lost time • The wider range of the MPP operation voltage to improve the PV module utilization • Charging power & charging current limit function(BATT1) • High quality and low failure rate components • Digital circuit control of adaptive three-stage charging mode • BATT1 type can be set via LED/LCD • Product runs into the low self-consumption mode if PV voltage is lower than 5V and there is no manual operation for some time. • 100% charging and discharging in operating environmental temperature range • LED and LCD display units optional • AES control signal for car refrigerator to avoid energy waste • Standard Modbus protocol and RS485 (5V/200mA) communication port for the customer to expand the application area Solar Backpack
