Why I have no power from solar when grid is off?

When the electrical grid is off and you have solar power, you will not be able to run anything in your home that requires mains electricity, such as outlets, lights, and appliances. This is because the power you get from the solar panels is not converted into the type of energy that is needed for everyday appliances and devices.

Solar power works by converting the sunshine’s energy into electricity, which is then stored in a battery to be used when needed. If the grid is off, your energy is not connected to it and so you won’t be able to access it to power your devices.

In order to have power from your solar system when the grid is offline, you’ll need to have an off-grid charging system set up. Such a system consists of solar panels, energy storage batteries, and an inverter, plus additional components like charge controllers, dc-ac converters, distribution panels, and so on.

With this you’ll be able to enjoy your own power supply even when the grid is down.
