Frequently Asked Questions
What battery voltage does this 4.2kW inverter support?
A: This BSSI-V-GN4200 model is designed for 24V DC battery banks, compatible with lead acid, AGM, gel and LiFePO4 lithium batteries. If you need 48V version, choose our 6.2kW GN6200 model.
Q2: Can it feed excess solar electricity back to the public grid?
A: Yes. It is a hybrid grid-tie inverter with grid feed-in function, which can automatically export surplus solar power to the grid for electricity rebates under compliant grid connection conditions.
Q3: What is the maximum solar panel power it can connect?
A: Max PV input power is 6200W, PV open circuit voltage cannot exceed 500VDC, MPPT working range 60–450VDC.
Q4: Does it work without batteries in grid-tie mode?
A: It requires a 24V battery bank for normal startup and stable operation, the battery acts as energy buffer for grid-tied feeding and off-grid backup.
