It is 9am and there is a power outage i.e. no electricity is provided by the electricity grid. Currently it is sunny and our house is relying 100% on the solar installation (solar panels and inverter) for the fridge, freezer, computer, WiFi and gate motor.
In South Africa, power outages continue on a daily basis.
A solar installation is not complicated to install if done by a competent electrician, it does not have to be expensive and it is peace of mind.Brian Gilder
From the image below one can see that at this moment in time, all the power is being supplied by the solar panels. Should it be overcast or a rainy day then I assume power will be supplemented by the battery viz power for the home would have to come from 1) the solar panels and 2) from the lithium battery. But since it is a sunny day, all the power is currently supplied by the solar panels.
Should the solar panels, lithium battery and 3Kw inverter last a few years then this was obviously a good investment. Currently we are scoring due to the fact that: 1) we keep the fridge, freezer, computer and all lights on (lights are obviously needed at night) and 2) we are saving on the electricity bill.
