Question:

My Travel Trailer is wired with 50amp wire, and I have a 12v 100mah lithium battery. Which inverter do I need that doesnt exceed the wiring in my rv? Thanks!

It can be tricky to pick out the correct size inverter for a trailer as the main contributing factor is really the load from the electronics, not necessarily the battery size. Therefore, even if the battery/batteries have been changed it is best to use the same size inverter. The Progressive Dynamics Inteli-Power RV Converter and Battery Charger part # PD9160ALV for example is rated at 60 amps. I have attached a full list of options below.
