2500 OLTEANP 12 Volt inverter designed to run AC loads from 12 Volt battery.
Bought it for my RV, but decided to go with a larger Inverter with more features. It retails for $260, but I would take $200. This inverter has been only run for testing, it new in the box. I can show it works using the AC 120V plug prior to purchase.
It also has an automatic transfer switch that when connected to shore power it automatically shuts off and will also automatically turn on and start invertering when AC shore power is lost. Great feature for boats and RVs.
