I have at my home a Microtek Inverter / UPS 875 VA E2. Today, when mains was cut, I checked output voltage of the UPS and it was 300 volts without load and 280 volts with moderate load (not full load). Altough, I am using this inverter for more than 1 year and have no other problem, yet the output voltage must be 220 v (plus minus 5%). Can any learned friend from this forum suggest how I myself correct output voltage around 220 volts?
