4000w DC To AC Pure Sine Wave Off Grid Hybrid Solar Power Inverter
The 4000W pure sine wave inverter can converter battery power or grid power to pure AC power for AC appliances, such as TV, fridge, air conditional, radio, ac lamp, laptop and so on. It is working for off grid power system with battery, after you connect it to battery, you will able to power household appliances in areas with no access to mains electricity, such as in a motorhome, caravan, boat, farm or any other remote location.
1. Features
- Low frequency transformer
- 3 times peak power
- LCD+LED display
- Pure sine wave AC output, input and output design isolated well
- High efficiency conversion, more than 85%
- There are three working models, battery first model, AC first model and saving energy model, users can choose according to different demands
- Users can adjust the AC power charging current, max. current is 50A
- USB port, RS-232 works well with SNMP or other remote control
- Protection against under-voltage, over-voltage, over-load, short-circuit and over-temperature
