From pv magazine India

South Korea's Daewoo has developed new lithium battery inverters for solar projects. The hybrid inverters are available in rated power outputs ranging from 0.5 kVA to 10 kVA. The built-in LiFePO4 lithium batteries eliminate the risk of acid leakage.

The 1 kVA and 2 kVA inverters come in a compact, portable design. They can be wall-mounted or used outdoors as reliable power banks, according to the company.

The inverters can handle maximum DC input voltages of 25 V (for 0.5 kVA model) to 230 V (10 kVA model) from solar panels. The maximum recommended PV input power is 100 Wp to 10 kWp.

Daewoo said the changeover time in UPS mode is less than 10 milliseconds.
