![]() That is, until the time I forgot to flip it, and went to bed. I just flipped the circuit breaker for the converter before turning on the inverter. You recall that the converter and inverter should never both be on at the same time? No problem. With one modification, this is how my current RV is set up. When you want inverter power, you just unplug the RV from shore power and plug it into the new 30 amp receptacle. RV Inverter Installation Method 4.Ī good compromise is to install a 30 amp receptacleon the outside of your RV and then connect it to the output of the RV inverter. This RV inverter install method means having some outlets that don’t function when you are on shore power which could lead to some frustration. The difficulty in accomplishing this type of installation will depend on where the outlets are located, and how hard it is to get wire to them. You can either install new outlets or disconnect existing outlets from the distribution box. Slightly less crude, is to connect one or more dedicated outlets to the inverter. Though a simple RV inverter install, it left me tripping over the cord on a regular basis. It gets the job done, but we very soon got tired of plugging and unplugging different devices into the extension. My first inverter installation worked that way. RV Inverter Installation Method 2.Īt the other extreme, you can run an extension cord from the inverter to whatever device you want to power at the moment. If that seems like a more complex RV inverter install than you want to try, read on for how to use a relay. The most common method for achieving this is to use a split distribution panel, with the converter on the part of the panel that is not connected to the inverter. If you go this route, you still have to avoid powering the converter from the inverter. The switch will automatically select shore power if it is available, and inverter power if it is not. The most elegant (and of course, most expensive) solution is to connect the RV inverter directly to RV’s AC distribution boxthrough a transfer switch (keep in mind the type of switch used varies based on the power of the RV inverter and if you have a generator). That will happen even if no load is connected to the inverter. You will very quickly run down the batteries until the inverter shuts off for low voltage. Since neither the inverter nor the converter are 100% efficient, each trip that current makes around the loop will waste some power as heat. The problem with having both on at once, is that you are pulling current out of your batteries with the inverter, while pushing current back into them with the converter. However you do it, you absolutely must ensure that you do not have your converter turned on when the inverter is on. Whichever option you select, you can do the wiring with standard 14 AWG, household type nonmetallic cable. There are several possible ways to wire your inverter. But in any case, you need to ensure that you don’t have either shore power or generator power connected to the output of the inverter. The AC (Connecting the inverter to the RV electrical system) side of the RV inverter install can get more complicated. You might get lucky at your local welding shop. If there is a supplier near you, see if they will sell the short lengths that you need instead. ![]() Welding cable comes in larger sizes, but is expensive as many times you have to buy a whole spool.
