Standard and Certification

EMC, UN38.3

Rated Energy*: Test conditions, Cell Voltage 2.5~3.65V, 0.5C charge & discharge at+ 25 ± 3°C.

Usable Energy*: Test conditions, 90% DOD, 0.5C charge & discharge at +25±3°C.

Max. Continuous Discharge Current*/Power*: Max. Continuous Charge/Discharge and power de rating will occur related to Temperature and SOC.

*1: The actual charge and discharge current also depends on the battery.
*2: Under off-grid mode, then battery capacity should be more than 100Ah.
*3: When there is no battery connected, inverter starts feeding in only if string voltage is higher than 200V.
*4: Can be reached only if PV and battery power are enough.
*5: The standard configuration is CAN.
*6: Only compatible with 2.4Ghz network.
