VOLKER-4.2KW hybrid inverter is suitable for household appliances, power tools, industrial equipment, and electronic audio and video equipment use, maximizing self-consumption rate of solar energy and increasing your energy impendence.During the day, the PV system generates electricity which will be provided to the loads initially. Then, the excess energy will charge the battery via VOLKER-4.2KW. Finally, the stored energy can be released when the loads require it. The battery can also be charged by the diesel generator to ensure uninterrupted supply in the event of grid blackout.The power inverter has 360°all-round protection with a number of protection functions, including short circuit protection, over voltage and under voltage protection, overload protection, reverse protection, etc.
