Inverter install

[vic]

Hello all, I purchased a 2026 delta 292rl and love it. I know its inverter prep ready as far as the receptical.
My question is, can I use the existing bus block to connect the main power or do I have to come directly off my batteries. Thanks all so many youtube videos that I got confused! Lol

When connecting/adding an inverter, you can use a busbar, then to inverter. You will need a large (400amp) fuse off battery, before busbar.

Here is my setup, a bit more than you're planning, but will give you a good idea on how to route power.

Wonderful thanks so much!

Wonderful thanks so much!

So after connecting to the existing busbar that has all power connected, add a 400a fuse and then add a disconnect switch? Sorry just trying to have it clear!

There is more to this. You will need to determine your inverter size and then replace existing cables coming off battery. Most likely you will need 2/0 or 4/0 AWG to be safe. The busbar you have....from factory? If so, it is most likely not rated to handle the amp draw an inverter will draw. I use and would recommend a Victron Lynx Distributor



You can see I have 2x of them in my install. The busbar on the far right is the factory 12v busbar with thermal fuse connections. I keep that for small amp 12v gear. I moved my hydraulic jacks/slides off of that busbar.

So running another batt cable from the battery leaving the other existing cable there connected to busbar . Then with new battery cable then add fuse, disconnect switch etc. Getting a Pure Sine 2500w with auto transfer switch .

I'd recommend removing all cables from battery...route new cables to Victron Lynx...then pull 12v from there for the existing 12 bus bar and your new inverter. You can see how I did this in my image above.

try this...

Yep watch that! Thanks so much!

Umm, probably poking the bear here.......Look at those Battle Bomb Batteries............

Trust me, I have already had a LONG coversation with BB. I was under contract with them for a year, but no longer. They have agreed if I ever have an issue, they will make it right. Time will tell.

I just wanted to jump in and ask, I watched the video that was posted in this chat. Did exatcly was on the video. Looks like I only got 1 leg to turn on which powered specific outlets, microwave and tv. I removed my lead acid batteries that were connected to the front of the RV and stopped getting power to my slides. My understanding is there are two legs, each host specific power to different things. As I was able to use the inverter prep for my install, what am I missing to power the other leg?

That's how factory inverter prep works. Using inverter prep only supplies power to a select number of loads on one "leg", not the whole "leg". e.g. the microwave may be on the same leg as an AC but the AC won't work while running on the inverter.

I removed my lead acid batteries that were connected to the front of the RV and stopped getting power to my slides.

The hydraulic pump and slide room motors (if electric) use DC from the battery(s). A converter (which is likely un-powered now anyway without shore power) or inverter charging circuit cannot operate them.

My understanding is there are two legs, each host specific power to different things. As I was able to use the inverter prep for my install, what am I missing to power the other leg?

It'll be a whole new game to install a different inverter that powers both "legs" of 120AC — beyond the scope of this quick answer.
I hope that helps. I'm learning some things here too.
May I ask which inverter you chose to install? Thank you.

Do they explode?

That reminds me OC I have a lithium battery question for you?
I read a lot about lithium batteries getting over charged or getting to hot and catching fire?
with my new LI batteries do I need to worry about over charging when they are on shore tendor all summer?
thanks For the info
MR

The BMS in today's lithium batteries will shut down incoming power, once the battery bank hit 100% charge. No need to worry. There are some BMS systems that do more (control heater, protect from cold/heat...etc) However, all of them do the basic stop/start charging function.

I went with the Renogy 3000. So what would be the best way to power both legs? A lithium battery at the from with the factory cables for 1 leg, and a Battery at the front ?
