How to Choose the Right System Size for Your Home?
Answering the questions below will help you fully enjoy your silent power source and keep any disappointment at bay!

What do you expect to run?
What would you like to run at the same time?
For how long?
For instance, if you would like to power at the same time:
- A fridge and freezer,
- A weel-pump,
- A furnace,
- A laptop,
- A TV,
- Some LED lights,
- And Charge your cellphones,
Our SMG Basic will work well and do the job.
However, if you have an electric water heater, electric heaters to heat some rooms, a washer-dryer, a large A/C, and an electric boiler, we are not discussing the exact needs.
In this case, you require a significantly larger solution, especially if you intend to run them simultaneously. In this case, you will need our SMG Essential for homes or SMG Pro.
Now, you know that you can power these appliances AND simultaneously.
Next question... For how long?
The only answer to this question is that we don't know. At WattXpect, we provide real solutions, not dreams!
Understanding how long you can rely on your SMG involves asking questions and conducting thorough research.
Below are some calculations we've made to assist you in finding out, but remember to first check the wattage requirements of your appliances to make your calculation more accurate.
