Well, since we don’t know you personally, and we have no way of knowing exactly how you plan to use your solar power system, we had to make some assumptions based on our own personal experience.
We’re assuming that:
- You want to run a 12 volt system (it’s what we run).
- You really don’t want to spend more money than necessary.
- You prefer saving money over having the ability to run two high wattage appliances at the same time (we’ve sized your inverter to power the single highest wattage item that you selected from our list). If you want to run more than one high wattage appliance at a time, you’ll need a bigger inverter than the one we recommended.
- When possible, you would like to see what voltage your inverter is running at, and how much current your inverter is outputting.
- You want a pure sine wave inverter.
Honestly, it’s pretty difficult to choose an inverter for someone else. It’s kind of like choosing a TV for someone else—I might like Samsung, but you might like Sony, even if the features are basically the same.
Personally, I use a Xantrex PROwatt SW 2000 inverter, and it has one feature that I really like: a digital display. The digital display tells me the voltage that is going in to the inverter, and how much power the inverter is outputting. I like to keep tabs on this information while I use my appliances so that I know by how much I’m taxing my system. This feature, in combination with affordable prices, makes the entire PROwatt SW line my top pick for appliances in the mid-range wattage levels.
However, I wouldn’t want you to spend more money than necessary on an inverter. So for the lower wattage levels, I recommended the Samlex PST line of inverters. This line does not have a digital display like the Xantrex line, but they are a bit cheaper and smaller. They’re great for small spaces like conversion vans.
For the heavy power users—for example, those who want to cook using an induction cooktop—I recommended a Go Power! 3000 watt inverter. Now, this assumes that you’re going to cook with high heat, using as much power as the induction cooktop will let you. If you’re okay sticking with low heat, the induction cooktop will also work with a smaller (and cheaper!) inverter, like a Xantrex PROwatt SW 2000, but you’ll have to keep an eye on the aforementioned digital display to make sure you’re not taxing the inverter too much.
Finally, since almost everyone uses something that runs best on a pure sine wave inverter (CPAP, laptop computer, battery charger, coffee maker, alarm clock, etc.) I recommended a pure sine wave inverter for all wattage levels. If you absolutely know that you will never need a pure sine wave inverter, then by all means nix my recommendation and go for a modified sine wave inverter. They’re much more economical.
