Analysis Paralysis, AIO, or just replace inverter?

[DouglasPaul]

Current set up;
12 volt
4 various 100 ah lifepo 4 batteries
2 eco-worthy 280 ah lifepo 4 batteries
2 Victron 100/30 cc's
1 Victron 150/45 cc
4 255 watt panels
6 100 watt panels
1 Voltworks 12 volt 3000 watt inverter

2 250 watt panels on each of the 100/30 cc's.
6 100 watt panels on the 150/45 cc.


I have purchased 2 more of the eco-worthy 280 ah batteries. I want to change to a 24 or preferably 48 volt system. I'm also getting 4 more 250 watt panels for winter time.
I do not want to use the grid if I can help it.
The Victrons will not do 48 volt, only 24. So, I can stick with the Victrons and buy a new inverter, or buy a AIO such as the EG4 3000 or Powmr such as this one; https://www.ebay.com/itm/166721756947?var=466366003298
Or this one would do nicely https://www.ebay.com/itm/306098335345 ,if it's reliable. I have never owned this brand,

I do not mind putting the Victrons to other uses, the inverter will need to be replaced regardless and sold or used elsewhere. I'm thinking the all in one will reduce the clutter under my kitchen sink which is where the cc's, inverter and two 280 ah batteries are. (I am full time in a 28 ft. trailer) The 2- 280 ah are being relocated when I get back to Washington and I get the two new 280 ah batteries because all 4 will not fit there.

All opinions and recommendations are welcome.

What are the specific reasons you want to move to 24v? Or 48v? With only a 3000w inverter and no additional panels, i dont see any benefits of switching now.

Fyi, The victron 150/45 will do 48v.
The 100/30 will not.

The mixed bag of batteries will be an issue. My opinion is to stay 12v unless you want to start over completely.

One reason is the relocation of the 280 ah batteries, they are going to be 8 to 10 feet away from the inverter and cc's, that's a lot of copper. Also, I am adding 4 more of the 250 watt panels.

I'm also in a travel trailer full time, but stationary and have all my equipment in a metal cabinet outside... Is that an option or do you need to be mobile? I'm not sure I like the idea of all that equipment under the sink - one small leak and it could be a bad day... Travel trailer manufacturers aren't exactly known for having the best quality construction, then add in age and vibrations from going down the road.

I've used PowMr all in ones for over year now without any issues - I have both the 24v and 48v in your first link. Keep in mind their starting PV voltage is 150v before they start producing. The high VOC is good if you have bigger panels but I'm not sure the specs on your current panels so can't say if they would be a good match or not.

Since all my hardware is outside, I just added a 30a plug to the output of my inverter so I can plug the shore power cable from the trailer into it to simplify wiring. Initially I just ran everything off the 24v 3kw, but later added the 48v 5kw and split the loads of the trailer. 5kw for most of the trailer and large cooking loads, and the 3kw for starlink, AC, and heat. Since I'm stationary I picked up a 24v 500ah forklift battery cheap and moved my 4x 24v 100ah batteries over to the 48v inverter. I've since removed the 24v PowMr when I found a 36v 1000ah forklift battery and now I have a separate CC and 36v 3kw inverter to replace it.

If you were to go 24v route you might consider ditching the mish mash of 12v 100ah batteries and pick up a couple 24v 100ah units or a single 24v 200ah.

After owning and useing a 12v system for 5yrs I would never build one again. It's a simple math problem on why not to if you can avoid it. 105a @12v is 1260w input to the batteries. 105a @24v is 2520w going into the batteries. Solar pannels are very cheap now, it's the batteries and charge controls that arnt so much. Keep in mind too that a typical charge controller can do more than a single voltage so in this case a 24v system is almost doubling your "value".

OP. Dont get an AIO, they have very high stand by power needs. Just get a quality inverter.

Just up and buying new batteries really isn't an option. What I have has been working fine in the summer in Washington and winter in Arizona, but we'll probably winter over in Washington this year and I need to add the extra capacity because of reduced sunlight. It turns out the 4 280 ah batteries will fit under the seat of the dinette so that's where they are going. I have a 30 amp outdoor receptacle bolted to the frame and hardwired to the inverter so I just put a 25 ft extension cord on the shore power cord and plug into it when we're not traveling, works fine. I was also looking at this model https://www.aliexpress.us/item/3256808329843832.html? but after both responses being negative to 24 and 48 volt I may just add another cc or two to handle the extra panels and stay with what I have going. I won't need them all when we travel and can just store them.
