7 Most POWERFUL Solar Generators for Your House | Buying guide
Updated: Aug 4
Solar generators are portable off-grid solar power plants with inbuilt batteries and you can charge them with AC power, PV panels and even with a car charging port. These portable powerhouses are rated between 200 watts to 3,000 watts. These solar generators are very convenient and effortless to set up.
However, to run the whole house on a solar generator you need to select the right size with a battery capacity big enough so that you can run your appliances for desirable backup time. So, what size of solar generator do you need to run your house? Here is an explanation.
As per EIA in 2020, the average power consumption of a residential utility customer in the US is 900kWh per month. Accordingly, for a day the average power consumption of a residential customer is 30kWh. Likewise per hour, the same will be roughly 1.25 kWh. Furthermore,1.25 kWh is equal to running a 1.25 kW load for one hour.
Therefore, this implies that the minimum rating of a solar generator needed to run a house should be 2,000 kW with a battery backup of at least 2,000 Wh.
To run a house should be 2,000 kW with a battery backup of at least 2,000 Wh.
Can a solar generator power a house?
A large-size solar generator that has an inverter rating of 2000 watts or above and a battery backup of sizes 2,000Wh to 10,000Wh can power a whole house for 2 to 8 hours. However, the backup time can be increased by reducing the house load.
