Build your system

Add each room of the home and the devices in it. The inverter is sized to what runs at once, with room for motors starting; the battery to carry the house through one grid cut; the panels to the energy the house uses in a day.

As a starting point: a 1.5 ton air conditioner 1,200 W, a fridge 150 W, a washing machine 800 W, an electric oven 2,400 W, a kettle 2,200 W, a TV 120 W, a router 15 W and an LED light 12 W. Every figure can be changed to the one printed on your own device.

Set how long the grid is off and how long it comes back, separately for the day and for the night. The battery is sized for the larger of the two, and the page says whether it can recharge before the next cut.

Yes. The inverter, the battery and the panels are machines cliky sells in United Arab Emirates; one press puts all three in the cart.
