Transfer Switches

If you’re going to be plugging into shore power, protect your system. If you have a whole-house inverter that does not support hybrid functionality or otherwise doesn’t have its own built-in transfer switch, you’ll probably want one of those too.

There’s lots of different ways that household AC wiring can be set up. If you’re on a very basic system where a couple outlets are powered by your inverter and you have a separate dedicated battery charger, you may not even need or want a transfer switch. If you have a hybrid inverter/charger combo unit, then the transfer switch concept is built into your inverter and there’s nothing you need to do.

If however you’re using an inverter that doesn’t have that feature built-in, then a transfer switch is probably the easiest way to get you wired up correctly. When the transfer switch kicks in, your rig is then being powered by the shore power or generator instead of your inverter and you have full access to as much power as the shore power provider can offer.

If you need a transfer switch, the only real factor to consider is whether to get a 30-amp or 50-amp version. That’ll depend on your rig and its electrical needs.
