1600 watt solar charger, allowingE-series Batteriesto be charged with solar energy.Does not include solar panels. Rated Voltage: 51.2V Charging Voltage Range: 41.6 – 57.6V Max CC Charging Current: 30A Power Rating: 1600W Max PV Input Current: 50A Max PV Input Voltage: 60V Efficiency: >99% Weight: 5.3kg Size: 233 x 262 x 100mm Solar charger is compatible with E60 and E163 batteries. Charger will have CAN communication with the battery, similar to a regular wall charger. Charger will automatically initiate and pause charging depending on input and battery SOC. Solar charger is conditionally compatible with E80 and E175 batteries. There is no CAN communication between charger and battery, so can only charge based on battery voltage. Charger will automatically stop once battery reaches 55V (the actual SOC may not reach 100%). Charger will automatically restart charging once voltage drops to 53V.
