how do i know what the charging on the individual batteries is doing. I say all of a sudden becuase the system is setup to shut off when ever the voltage go to 48v and and that never happeend once until it did a week or so ago.

not sure how to do that but i figure there screwed, going to just run solar during the day and switch to main power at night. Solar guy by me has quoted me for lithium batteries AES Rackmount by Discover anyone heard of them before

As for float and charge everything set to what rolls told me too. Which is basically what you said. But I pay attention. To the voltage in the am closely all the time. Never changed it for temp. Coldest it gets is 60 high is 98

What's temperature compensation? Live in Bahamas. Thought agms would handle heat

I never let voltage drop below 48 ever lots of times woul run generator for two hours into evening. It's just odd how this seems to of happened quickly

So I have an outback system. One day power died in house. Turned system off and on and power game back on. There was an error that said battery voltage error. I have a 48v system consists on 16 6v 415amp rolls agm batteries. At the begining of the day voltage usually reads 48.6 . I noticed...

I am years away from getting some lithium ion batteries hopefully atleast 6. I have 16, 415 amp 6v agms now that are a good, but I figure when they start to die will need to procure something new. And I know this is far off, but I figure I would like a atleast 20kw of usable power, does anyone...

The cables to the box are 8gauge. But the solar combiner to charge controller is 80ft if 6gauge. Occasional snap.can drop it to high 40s thats rare. Usually mid 60s for about a month but once sun is out almost always 70s. Need some extra juice as I need to run some window unit air cons as its...

Its 36nand vmp 9 somethjng

Says it maxes at 150. I just need a 5 prong bus bar it can easily hold 5 breakers

Outback 80amp charge controller. They said no more then 15 270w panels. As for bahamas changes weekly One week we're in 100 lock down can't even go to food stores or get water then were open only to be locked down again. I think are prime Minister is bi polar. I noticed some people made...

Can't add 16 panels as that would be 2 much and a series of 5 would have the volts to high

So I have 12 panels, 3 in series giving me 9amps 90volts x 4. and this go into a combiner box. This is my question I want to add 3 more panels, but I only have 4 prong bus bar, can I still add the other circuit breaker and use piece of 8ga cable to link them all?

Your in for info you probably dont want to know. Our code just got upgraded to canadas 2 years ago, no idea why. But they only inspect your house when you go to get main power put in that is it. I am living in dorian aftermath, they still dont have the sub cable to cross the ocean they forgot to...

ok, sorry for not posting my life story everyday, but supplies tough, and I dont care about efficiency at the moment as much as I do safety, so if 8 gauge will work but I loose more so be it. Take in mind i have done none of electrical actually had people do this for me and they recomended it...

go figure my budy a boat mechanic has all the wire I need, electricians dont, swapped out to 8 feet of 4 gauge and now there is no flicker when water pumps kicks in

Why is a 2 percent difference so important?

No that's the max configuration. For that array. Dont have easy acess to 6gauge. Coule double up on the 8 gauge

Wasnt sure wire worked like that. It just automatically flows into the one with least resistance then easing the load on them then

About to put panels on roof. 5 series of 3. 30v 9 amps each 270watt panels. Will need to run it 80 feet to controller. I take it 8gauge will work it seems do people use higher gauge. Seems gauge would become less flexible for running through conduit pipe

thanks for the help but different country, Bahamas, Abaco specifiacly, its a pita to get stuff here, but doable, just going to have to beg my brother to get it in nassau and through it on the mail boat, then take ferry to pick it up in 3 days later :)

the batteries are all wire together with 4 gauge, just wire tough to comeby me righht now.

When ever the water pump kicks in, 5hp hp it pulls about 1100watts, there is quick very brief dimin of the lights. I have the flexpower one outback system with a 3kw inverter can surge to 5.4kw. Could this be a wire gauge issue? I am running 8 gauge from batteries to system about 8feet away...

There is no best. Depends on bank voltage and lots of things. I have no shading at all on my roof inhave 3 in series 4 parrell.

Looks like you might have serious shading issues with those. Are they in parrell or series. Is there any shade covering them at all when you check them

There agm batteries and my waterpump is 1300watts when it kicks in granted it probably a total of 30 minutes a day at most

I have 12 12v 100amp batteries. I think there renogy. There called wieze but it looks like they just might be renamed that. Basicaly batteries are on from 7pm to 8am by 9pm the panels are begining to push out some good power. I only have 12 of the 15 installed now. Usually in the morning the...

Even if its charging the same battery bank? Thanks good to know thanks.

I currently have 15 270w solar panels connected to my outback solar charger this is set up in 3s x 5p set up I want to basically double that. So when I get the second inverter do I have to get the exact same panels and set it up the same way?

I have it. Now as 3 s 3 parrell so all should be good tomorrow. Thanks alot for all help

No. Now you going to make me write ba story. After dorian I knew I was going to be with out power for a year. A friend who lives ina solar community said he could arrange for a decent outback power system for 14k. Same time my best friend who is fairly well off asked me what needed I said...

Interesting these people said 60v would be ok for agm battereis

Agm. Generic chinese. Guess that can be tomorrow activity. What if I added a 3rd panel and did 3 in s 3 in parell

Which I cant get easily I am in abaco where dorian kicked the shit out of. And know travel restricted at least freight is flowing and usa has not shut down every industry like we did.
