Batteries supply 12v, shore power is 120v. You need an inverter to convert 12v to 120v. I have a 2500w Aims Power inverter/charger hardwired into the electrical panel on the trailer. It replaces the on-board charger, and supplies 120v to all the outlets. Inverters need to be placed close to the batteries, and require heavy cables to handle the high current at 12v. Since you are unfamiliar with electrical systems, please have a qualified RV Tech or electrician install the inverter. Here is the inverter https://a.co/d/0gtScwD3
