Inverters have a capacity, that, if exceeded, can burn out the inverter system or lead to power failure. Understand your load requirements to find the most effective power backup solutions.
Burnt rectifiers, rusted terminals, or an electrical fault in the mainboard can prevent your inverter battery from charging. This could mean a change is required.
If your present power solutions brand doesn’t enable better customer satisfaction. Then upgrade to a reputed brand that offers at-home maintenance checks and quick resolutions.
