An inverter is only useful if you are boondocking/dry camping and DO NOT want to run your generator.
Using an inverter requires a GOOD battery bank ! At least TWO 6V golf cart batteries
(the most cost effective solution). The other end of the spectrum would be 2 LiFePO4 batteries.
Must people also have solar panels to recharge their battery bank. Without solar, you will have to run the generator for charging.
By all means, you want a pure sine wave inverter. They cost more but work much better. I also highly recommend a combination inverter/charger/automatic transfer switch like one of the
Samlex EVO Series. Disconnect your converter but keep the DC distribution panel. Just hook the distribution panel directly to your battery bank.
What I really like about the Samlex EVO Series is all connection are made in one place. Much easier to install.
