Next to useless for people that want to go off the grid.
When i go solar it will be on a motor home and i will be useing a 48 volt system and inverter.
48 volt inverters are cheaper per watt output then 12 volt inverters as long as you are not looking for pure Sine Wave inverters.
Also you want Stackable Power Inverters. This allows you to run just the out put wattage you need without the heavy battery drain of a large
inverter.
The only need for a pure Sine Wave inverter is electronics like TVs or computers. you don't need a Sine Wave inverter to run lights refrigerator
fans AC unit. and if you use LED lighting system you will not even need a inverter for lights
Or in the case of a computer there are special dc power supplies just for this use.

One of the big reasons solar systems are expencive is people are being sold systems that are not using system energy properly.
only use AC where needed and if you can use DC it will be more efficient.
