 Auto-control function of charging power & charging current limitation(BATT1)
 High quality and low failure rate components of ST, TI, and Infineon to ensure the
product life
 Digital circuit control of adaptive three-stage charging mode to enhance BATT1
life.
 BATT1 type can be set via LED/LCD.
 The product runs into the low-power mode when there is no manual operation for
a long time and charging conditions are not satisfied (PV<5V).
 100% charging and discharging in operation environmental temperature range.
 Optional LED and LCD units.
 AES control signal for car refrigerators to avoid energy waste.
 Standard Modbus protocol and RS485 (5V/200mA) communication port for the
customer to expand the application area.
① Main battery (BATT1) is the energy storage battery for powering the
household loads in the off-grid system, supporting Sealed, Gel, Flooded,
LiFePO4, and Li-NiCoMn batteries. The controller can NOT automatically
identify the system voltage.
② Starter battery (BATT2), built in the vehicle, is the energy storage battery for
powering systems such as RVs and boats. It only supports a lead-acid
battery, and the controller can automatically identify the system voltage.
CAUTION
The BATT1 and BATT2 must be at the same voltage level.
