It’s ok, I am getting use to it lol I made a post about used units or broken units that people would be willing to part with and not a single person replied. So…. It’s all good

I feel that there are 2 ways to look at solar. 1. Designing a system based off certain needs for a certain purpose. 2. People that want to build budget systems with decent components for a SHTF situation with the pure objective that some power is better then no power. So what about a vid or...

The 80A are all set, hopefully tomorrow the bus bars will show then I can at least get this pack in place. Guess that concludes the battery portion of this, I should probably start a system build post.

Well I finally received my 80A breakers to use on each bank and have them retrofitted, I am just waiting for my mini bus bar to come in so I can make the links.

Any chance you would be willing to part with the fried unit ?

Does anyone have anything they are not using and willing to part with ? Also I am pretty good with with electronics and would even entertain a fried unit to see if I am able to repair it. Let me know the details if you have something. I appreciate it!

Yeah I have a bit of cable on hand lol I keep stuff I can use vs tossing it in the dump. I always barter and try to buy and sell stuff whenever I can too. So what I did was put the banks into series to create the 48v banks then ran main leads up for each bank so they would all join at the same...

I decided to run them all separately that way it can pull the load evenly, I can also monitor each bank this way.

Nice, do you think I should parallel 2 banks to keep the wiring clean ? Or should I run each separately ? Effects on balancing ?

yes my plan was to roll it under a work bench, yeah she is a bit heavy coming in at 960lbs I am pondering on fuses, breakers and wire routing at this point. Any suggestions?

Ok thank you I will look for that thread.

PowMr 5500W Solar Inverter 48V DC to 220V-230V AC,Pure Sine Wave Hybrid Inverter with 80a MPPT Controller, for 48V Lead Acid & Lithium, Support Parallel 9 Inverters and Running Without Battery https://a.co/d/dUhpVjq Any experience with this manufacturer at all ?

Here is the rack at this point.

I don’t really have intentions of deep discharges. But as of now I’m planning for brown outs and random storm outages. The rack is coming along good, I hope to have it done shortly then I will post some pictures. I need to sort out what 48v all in one I would like to start out with. Do you...

Well that is a plus, yeah I was scratching my head looking at it. If your assumption is correct of 80Ah @ 20C that bumps my bank too 15,350Wh

This is all the info have been able to find so far

Trying to figure out the capacity please correct me if I am wrong 12v 71Ah batteries 48v bank @71Ah = 3,408Wh 3,408Wh x 4 banks = 13,632Wh Also do you guys normally base the math off the 48v or the 51v it’s sitting at ? If it’s off the 51v it would slightly alter my numbers.

Well I was able to get 2 more batteries, so now I can do 4 48v banks. Hopefully tonight I can start building a rolling battery rack to get these into position then to start making all of my jumpers.

Well I am trying to get 2 more batteries so I can do 4 48v battery banks, Also thinking about the pros and cons of 24v vs 48v vs capacity but I am leaning on the 48v I am trying to track down 250w panels, I am also working on a list of appliances to see what my max usage could be. I might end...

Thanks for the insight! I will look into the post you suggested and see what I can use as a takeaway from it. What size PV system would you suggest ? Thanks

It was the price, I have them already and have 16 of them but told my father-in-law I would give him 2 so I could do a 12 or 14 battery bank. I also have some GC2’s I was planning on using for a small system but couldn’t pass on these AGM’s So I am trying to figure out what these will be...

Hello everyone, I am still learning and wanting to build my first solar system and wanted to get a general opinion on these batteries and being these are the batteries I have access too. I wanted to figure out what size of a system would suit these. I have 12 of these to use in the system and...
