There is a multitude of models available. You just have to pick the right one. Since this will probably be the most expensive component in your solar installation, there is a tendency to opt for a cheaper inverter just to save a bit of money. Don’t fall into this trap!

Its true that most lower cost solar power inverters are fairly reliable. However, they do not have the same robust overload and control features that are found on more expensive models.

An accidental system overload when starting an appliance may result in inverter or battery damage when using lower priced inverters. So its better to be safe than sorry.

If money is tight or you are using something that will only need RV or boat-type 12-volt DC lights and appliances, consider the 1500-2500 watt range. This is about as low as you want to go. But this is still able to power a refrigerator or microwave oven.

Also, I would recommend you shop around as prices can vary wildly.
