500 watt (550 VA) ups inverter with pure sine wave. 90% pure sine wave output, low distortion, waveform and main power line AC waveform are basically the same.
Tips: General Inverter vs. UPS Inverter
The general inverter converts ac to DC to charge and store the battery. In case of power failure, the DC stored in the battery will be converted to AC for the load to use. The primary function of energy storage inverter is to carry out the kinetic energy bi-phase transmission between ac power grid and energy storage battery. It is also a bi-phase converter, which can be compatible with all kinds of DC energy storage units, such as super capacitor banks and battery banks.
The ups (uninterruptible power supply) inverter can provide stable power supply for communication, medical, data platform and other network systems with special demand for power supply in the case of power grid outage or unstable power supply.
