>I have figured out few manufacturing lags in HOMAGE inverters. Want some touch?
-Longer switch over time.
-Voltage Spikes in modified sine wave current (especially in Vision models).
-180 V output during backup mode in idle state and LCD always displays 230 V.
-No stable charging current of 10 A with low input voltage.
>Desi UPS are worst in the sector of manufacturing defects.
>Do not want to speak about shitty quality of locally made batteries.
>Batteries do not get as quickly charged as you are estimating. There are power losses during the recharging process. No system can be 100 % efficient.
>It highly depends upon input. If input voltage is lower, then charging would always be slower. (rated charging current could be lowered with 1-2 A or more, it depends)
