i have a Xantrex 2000w freedom charger/ inverter and a Next-Gen 3.5k generator. Everything works as it is designed to do. My question is about how the boat was rigged. I will call Eastern but would like your opinion. There is a shore/ off/gen switch. When you plug in the boat to shore the Xantrex charger turns on and charges the duel 8d batteries. The shore switch does not have to be in the shore position. Nothing else AC works. Put the switch to shore and the boat powers up with 120 AC voltage. Batteries charge as they should. My Generator does not have any battery charging output. This is how they are made. So running the generator actually can run down the batteries do to electric fuel pump. Turning the master switch to GEN powers up the AC to the boat. Everything works but the Xantrex. The display never sees AC volt in. Therefore I am not charging the batteries. So when on the hook I can only charge from the main engine not the generator. This is how it is factory rigged. I know I could add a charger. But why do I need to and why did the boat leave the factory with no way to charge the batteries with the on board charger. The Xantrex is also an inverter. When the boat is not plugged in it will make 120v. The master switch must be in the shore position to power up the ac panel. This also works properly.
