Under this mode, the inverter is not able to connect to the grid. Either solar power or battery
power becomes major power source. When PV power is strong, the inverter will power load first
and the remaining power will charge battery. When PV power is too weak to charge battery or
power load, the inverter will convert battery power to supply loads.

When the inverter is not connected to the grid and there is no load connected, PV power will
charge battery directly.
PV Compatibility
This hybrid inverter is designed to generate continuous power from three different power
sources, PV solar modules (solar panels), battery, and the grid, depending on different power
situations. When MPP input voltage of PV modules is within 150 VDC to 500 VDC, this hybrid
inverter is able to generate power to feed the grid and charge battery. This inverter is
compatible with PV module types of single crystalline and poly crystalline.
Note: When PV input voltage is lower than 250V, the power of inverter will de-rate.
