Thank you.

Okay, sorry that made no sense to me whatsoever! Complete beginner here.

And also, is my inverter compatible?

The retailer is telling me that my inverter is not compatible with lithium batteries... But another is trying to sell me three pylontech us3000. I am not sure which way to go. Would there be any benefit to 3 x US3000 over 2 x US5000 ?

I have already replaced one. Thing is I am reluctant to replace two more and end up having to replace the lot anyway. They are €450 each! think I am better just to start again with a smaller lithium , I can get the polytechnic 4.8kw for €1500 and save the hopefully good batteries for another...

I am not sure on the equalisation settings I should use, maybe I could try that but I don't think it is recommended for the sealed batteries? Also the separate charging whilst in situ, I don't even know how I would do that. I would have to buy a charger. I do have one but it is a fast charger...

Will definitely add the fuse and disconnect. The inverter readings were recording around 26kw on a good day. But it is dropping now to only around 3kw. Because the batteries are showing fully charged and my load is very small. Also had a couple of cloudy days so difficult to give an accurate...

On that now

Okay will do. Also, the solar array to inverter does not have any circuit breaker and I am pretty sure it should have. Mixed readings from Google that I am struggling to comprehend.

Thank you. I have already been looking at possible upgrades. My budget doesn't allow for any at the moment. I had to get a loan to manage this set up. Obviously if the batteries are already done for them I need to figure something out. But I will give it a few days and see what happens. I have...

Honestly. The installer was just some bloke off Facebook. I know I know! I am a woman, my husband has had to leave to work in England. I live on a Spanish island and I am alone up here in the mountains with my two boys. Okay so I am not an idiot. I was kinda desperate to get power but now it's...

Thank you. I will get weeding tomorrow. It was completely dry and dead but the rain we have had is unusual and everything has grown like crazy.

Sorry for the incorrect units. I rushed the post to make sure I didn't miss replying. No I only have 12 in series. The other two are doing nothing. Okay. That's something I couldn't figure out but will change it now. I haven't seen the charging current go above 30A so far I don't think...

Okay, that all sounds a bit complicated but will re read it and see what I can do.

Haha. Yes it probably does look casual. They are set up in a cave. Definitely the coolest place here especially in the summer. The temp stays pretty constant. Okay, I will try and get some more measurements. Probably tomorrow because it's a little overcast now.

Can't charge off the system. No grid connection so if I disconnect I have no way to charge offline... Hopefully the new setting might help them recover.

Will check and make sure now

Yes, that's the one

I am not sure. I only just changed the settings. The previous setting had the max charge at 56v and float at 54v they were reading 6.2 at those settings. I will keep checking over the next few days

Fuse yes.

Not sure about equalisation. I read not to, that GEL batteries don't require it and then read somewhere else that it should be twice a year. No idea at all what settings I should use if I should do it. I mean, I guess I really don't have much to loose right now. Maybe I should try and figure...

Okay so my next questions, if the batteries don't improve would be about what would be compatible. The guy I spoke to about a lithium batter told me that it would have limited capabilities with my current inverter. But I guess we can get to that in a couple of days.

I have around 12 hours that I use power from the batteries, from around 8. My daylight hours here are long. But if I am right, and this is only what I have learned over the last few days so please correct me) 424ah x 48v should give me 20,345w divided by 2 for 50% discharge leaves 10,172w over...

Thank you, was just trying to figure that out!

Yes! By 10am they are "fully charged" according to the inverter. I posted a picture of the charge settings I have just tried to change them. Obviously I know that the cut off voltage is too low.

Post 16? Not sure what that means? Am I answering incorrectly ? new to forums. Yes I live in Tenerife up in the mountains. I have an animal sanctuary that is driving me into the ground!. It's beautiful and green up here at the moment because we have had tons of rain but it's usually dry and...

I posted before...you just mean of the set up right?

But he also told me it was impossible to set the right charge parameters... Which you guys have told me is incorrect.

He said that they are reading 6.4v each which is what I get also. But that the inverter will not charge them. He said they were badly damaged but would maybe still work with a new charge controller...

As soon as the sun goes down they are dropping fast to 43v and by mid evening everything is shut down.

Yes

They are 600ah/100h or 424ah/c10. I am only drawing a maximum of 200w through the night.

Thank you Mike. No help from the installer and I had another installer here yesterday that told me it was impossible to charge the batteries correctly with my inverter and that I needed to install an mppt controller that bypassed the one integrated in the inverter. He suggested a victron €855...

I don't have any shunt based monitor
