Split Phase 1KW to 6KW Solar off Grid Inverter

LS series low frequency solar inverter with power from 1KW to 6KW. This series inverter can do split phase output voltge, like US 110V/220VAC, 120V/240VAC voltage. The inverter can do with or without built in MPPT controller, also can connect with external PWM/MPPT controller to have more solar power input. Big toroidal transformer. strong load ability to support loads, such as AC, Pump, etc. inductive loads. Three working mode: Mains priority mode, Battery(solar) priority mode, Energy saving mode. It works with different type batteries, like lead acid battery, gel battery, deep cycle battery, LifePo4 lithium battery, etc.

Feature
