I think I have the same unit. It is very heavy. It has a large transformer that provides nice clean sine wave power. The one thing I don't like about it is you have to turn it on to get shore power. I would prefer that was automatic. It will run the air conditioner, but not long unless you have a huge battery bank.

Interesting!

@Les1 as you know there is no room under step. I was able to get my 300a fuse and battery monitor shunt down there. I placed 2 runners front to back to get inverter above hoses and created a chase for ac and dc wiring. I ran runners side to side to mount inverter to over the trough.I removed sink drains so they could be rerouted later. I installed a 30a breaker in a custom made electrical box and fed shore power to it then to inverter. From inverter to transfer switch. The dc I ran from the...

Witch inverter did you get? I can post more pics and provide more assistance. Right now it's late and really hot in the camper. The job took me a bit and alot of trial and error but the end result is i got 115v whenever I want it. I can run most everything. It's quiet and super convenient. I myself have plumbing, electrical and automotive experience so the job was in my wheelhouse. Any assistance hit me up.

Thx @gerald855s That area is tight! Did you do anything regarding ventilation, or did you figure there is enough in that space under the sink?

Gerald, Your LOA name suggests you have a 855s truck camper, like mine, so I’m familiar with the space under the sink. I recently ordered an inverter, and trying to decide where to place it. Under the sink, or under the step up, are two likely spots close to tne batteries. Could you provide more information regarding your install and wiring? Pictures would also be appreciated. Thanks Les

@Les1 I added a small 12v fan and a thermostat to vent the space. The space under stove is open to the vent below the drawers. When the camper is not in use I just leave the door cracked. I'm plugged in all the time so inverter kicks on and off when topping of batteries. I found a matching supply grill and cut it into side of cabinet for fan intake. There is a small void between the outside of cabinet that needed to be sealed to keep from recirculating air from the compartment.

When you stop and think about it, makes sense! I guess had better review my shopping list. Thank you (I think 🤔)

This and many more money spending tips are available here on LOA.

Our Aims 2k pure sine inverter has been working well. It will run the 9000 btu AC for 1-1/2 hours on 2 100 ah battleborns. Lowes had the best price with military discount.

I'm looking into an inverter as well... why 3000 watts? I was thinking the renology 2000 watts, now you have me wondering. Thanks!

I can't answer for anyone else, but I put 3000w in mine because it CAN run the AC, and has a bit of headroom leftover for a knicknack or two (like a desk fan, which does a good job circulating that cool air). Not for long (I "only" have 400ah of battery), but there have been times it's paid off. If I pull into a rest stop for a break and the trailer is sweltering, I can kick on the AC for some relief while I rest and get a snack. Or at a Harvest Host and I just want to run it for a bit...

Thanks John... we have a 15k AC, so I think we'd need larger inverter. Front reciever hitch? Is that for backing in or a bike rack?

This is a great idea; I forgot I could set alarms and I really really should.

@J Greg the honest answer for the 3k watt inverter was the 2k and 3k were physically the same size. We never intended to run a/c off of inverter so that was not a consideration. With the current battery bank 2 group 27 lead acid I would probably get an hour of run time but I have that option. When existing batteries go belly up I will go to lithium and have more available power. The 3k also will do 80amp bulk charging vs 60amp on 2k. My existing converter dosen't have the option to charge...

The hitch is mainly for bikes. I never thought about running the AC on inverter when looking for one but on the last trip I tried it. Now I am hooked on the option .😎

Guys the unit just dose an absolutely dynamite job charging the batteries. It bulk charges quickly then slows down to eventually trickle charging the batteries. Honestly t think that's where alot of the weight of the unit comes from. Unit is 22 x 10 x 8 I believe @ 60 lbs.

I've been there and done that! When I set up the BMS programmed an alarm to sound at 10% SOC in of the 702 BMS. With my battery bank that would leave me with about half of the energy in my former 2x group 27 FLA bank (37A). Enough power for me to react and fix a problem. It worked when I forgot and left the fridge on auto. It took a minute for us to figure out what the beeping was and find it was coming from the 702 as it was a new sound to both of us. @gerald855s - Thanks for posting this...

I always try to size for what if. Recently had an issue with my on board generator and considered removing generator and replacing with new Cummins Onan inverter generator or just using the space for adding like 6 more lithium batteries to the rig saving a ton of weight. Ultimately I just had to replace fuel lines and generator runs like new. So that put the brakes on that. Looking to add more batteries but that just a future consideration. Weight on my truck is somthing I'm leary of adding...

Just replaced fuel lines and did 20 hr service. She runs like new now. I do all my own work and service. Don't trust most services. If they don't think you know anything they will try to rip you off. On member said he was quoted 1800 to do what I did in a couple hours.

Watch out for those Cummins Onan genneys. Mine lasted 50 hrs

Yes, I am aware of that, I have the 2000 watt version. Your initial post shows, and links to, the straight inverter, not the inverter charger that you installed. Go back and check it out. I'm interested in changing my current inverter over to something like the one that you used. Not sure yet if I'll stay with another Renogy unit or look into something different. I will say that my current Renogy inverter has served us well, just looking for something with a built in charger. I should have...

Sequoia454 that is just a straight inverter the inverter charger pictured below is almost 700.00 and about 60 lbs.

So I've had this unit installed a while. What I like. Being able to to run all of my 115v accessories in the early morning without having to start generator. We use the 115v microwave and coffee pot usually before 10 am. Most campgrounds prohibit running of generator before 10 am so having the inverter comes in handy. If we do ever run the generator the charger portion of unit has an 80 amp bulk charging function that rapidly recharges batteries way faster than factory inverter. Cons. Size...

Did you link to the correct unit? Amazon description doesn't indicate a charge function on this one.

I can fix the link problem.

Sequoia 454 not sure where that came from. I didn't include it in my post.

That's odd, now I'm curious how that happened. In any event, thanks for the nice review and writeup, it has me thinking about changing out my inverter.

Sequoia 464 the price has dropped significantly since I purchased mine. The 2000w inverter charger is the same physical size as the 3000w so mainly the weight and output are different. The 80 amp bulk charge especially for lithium batteries is massive. I have my built in converter turnd off it dosen't do lithium batteries anyway. Mine is in a small area under the sink but noise is not an issue. Runs micro and Keurig in the morning flawlessly without having to run generator then solar refills...
