Golden Solar! Advance Power! Green Life!

RA Serires Solar Inverter/ Charger
RA series is a combination of inverter, AC charger with 300% surge power, AVR (Auto Voltage Regulation), Auto-transfer switch into one complete system.
Key Features

Pure sine wave solar inverter


300% surge power

Smart remote control (RMT)

● Configurable AC/Solar input priority

DC start & automatic self-diagnostic function

Compatible with both linear & non-linear load

Designed to operate under harsh environment

Easy to install & easy to operate & easy to solve

Low DC voltage supports home & office appliances

Powerful charge rate up to 120Amp, selectable from 0%-100%

High efficiency design & “Power Saving Mode” to conserve energy

Battery priority mode, designates inverter-preferred UPS configuration

13 VDC battery recover point, dedicated for renewable energy systems

8 pre-set battery type selector plus de-sulphation for totally flat batteries

4-step intelligent battery charging, PFC (power factor correction) for charger

8ms typical transfer time between utility & battery, guarantees power continuity

15s delay before transfer when AC resumes, protection for load when used with generator
