Low-frequency series inverter adopts powerful transformer
which has the advantage of impact loads, like pumps,
motors, and some high-torque devices.

1. Flexible Design
Flexibly schedule in Charge time
PV and Grid power the load jointly
Grid or Solar input priority
Work with battery or without battery

2. Batteries used:

LiFePO4 cells: real grade A CATL, GXHT, CALB, LISHEN and other new brands.

3.3. OEM/ODM:
Customized technical solutions with different brands of inverters different numbers of solar panels, different wattages battery, different installation methods.


Charging mode:
Support both Solar PV and Grid Power.
Flexible application, can set PV priority, Grid priority, Hybrid charging according to the actual application requirements.
