We bought a camper with a victron system, has 2 lithium batteries, 4 panels and a multi plus II inverter. Whoever installed it changed the shore power cord and plug to an L6-30p (240v), our assumption is this was to support the hybrid function on our inverter, but we would like to use our Honda 3000 generator for the AC in our camper. Which needs an L5-30 (120v) plug/cord. Can we change out the cord/plug without messing up the inverter and system installed?
Since you mention 240 and 120 I’m assuming you are in North America, in which case why not change it to the industry standard nema 14-50p and use a standard dog bone adapter for what ever you are plugging into? Neither an L5-30P or an L6-30P are going to be available at any rv park or campground pedestal.
Is your breaker panel wired to use split phase 240V?
If it is, you could make up short cable (dogbone) that connects the two 240 hots to the single 120V hot. We do this on our 50A coach to use 30A & 20A shore.
Can you explain this a bit more about and like I’m 5 years old lol… I don’t really understand electrical stuff very well.
Our camper came with a bunch of dog bone adapters that we think will work on shore power but we are terrified to try one and mess something up lol
Honestly I’d steer a 5 year old away from electricity, but a 240V plug has 4 wires total; 2 hot wires that are 120V each (with respect to neutral), one neutral and one ground . IF your camper’s electrical panel is wired to accept 240V, there are usually 2 sides to the panel and each is fed from one of the hot wires from the 240V. With that said, I don’t ever recall seeing 240V 30A in any place we’ve stayed, so that’s a bit of a non-standard plug you have. Usually 30A for RVs is 120V 3 wire, one hot, one neutral and one ground.
Is the camper new and this install was from the factory, or is this a previous owner’s retrofit? How many air conditioners? Is the main breaker a double pole or single?
The dogbone adapters should work okay, but if it’s a DIY retrofit, you never know what you have until you dig into it. Have you ever plugged the RV in?
Hi! We bought this 2003 camper from someone who wasn’t very forthcoming with the details, she had the solar installed and I’m guessing the cord replaced, our plan was to get a portable AC got use and plug it in the generator, and eventually figure out our plug situation lol.
The only concern we have is plugging it in at a campground and it causing issues with either our system or the shore power.
I think this week we are driving up to a local campground and asking the camp host if we can just test the plugs to see what happens. Figured they may have a free spot for us to just try it out lol
Also most 5 years olds would probably do better than me hahahaha
Not too sure you can hurt the Multiplus unless you feed it 240V on the 120V input, then you probably will have an issue.
Probably a poor weekend to look for open spots, unless it’s not a very popular spot.
