CE off grid Solar Inverter Online DC12v AC 220v/230v 500w 1000W solar inverter efficiency rate 93%

?

Model :?LI-50112

?

Multifunctional operating interface:

?

?

a. Adjustable mains priority and inverter priority mode:

Mains priority: When AC mains and DC battery are connected at the same time, inverter chooses AC mains for priority AC output.

b. Inverter priority: When AC mains and DC battery are connected at the same time, inverter converts DC battery power for priority AC output.

Customers can choose mains priority or inverter priority mode according to their own needs, and can switch them at any time.

?

Switching power is supplied by independent system

It uses a separate power for a single switch chip, which reduces the interference of pulse and make inverter works stably.

?

Full-bridge rectifier and PCB structure is highly optimized. Input and output circuits are truly isolated.

PCB is highly optimized, which is insulated and isolated by modularization. Full-bridge front-end circuit rectifies and provides outputs, back-end circuit transformer controlled by intelligent program. Input and output circuits are truly isolated. And model number, production date and batch are printed on the PCB for tracking.
