Off-grid inverter working mode: connect solar panels to supply power to the load and charge the battery at the same time; you can use the grid or battery to supply power to the load; but cannot feed electricity into the grid.

On grid pure inverter (string inverter or central inverter, etc.) can only connect with solar power and grid, in which grid is used as AC source. Off/on grid hybrid inverter can work with battery as DC source or generator/Grid as AC source. Meanwhile,  grid still can charge the battery no matter off-grid or on-grid hybrid inverter. Main difference between off/on-grid hybrid inverter is off-grid hybrid inverter cannot sell extra power to grid.

Lithium battery, lead-acid battery.

2KW inverter is equipped with 12V battery; 3KW-6KW inverter is equipped with 24V battery; 7KW-10KW inverter is equipped with 48V battery, which can connect batteries in series or parallel.

Polycrystalline solar panel, monocrystalline solar panel.

PV working voltage range connected to the inverter in series, and the open circuit voltage does not exceed the maximum voltage of the inverter, or else solar panel will be bad in low temperature. Solar panel current in one MPPT cannot surpass inverter input capacity in one MPPT, or else there’s power limitation.

No. we’d better configurate the solar strings of one MPPT with same quantity, same model and same brand of solar panels, thus it can better achieve MPPT function.

Can be connected to gasoline generators, diesel generators. The output of the generator is connected to the AC Input of the inverter. The generator power cannot be less than 2 times the inverter power.

The inverter has the function of automatically starting and stopping the generator.
