Yes, you are talking of battery low voltage cut off, I am talking about not charging the batteries above 80%, any ideas how that helps to prolong battery life?

ojesymsym:
I read that the iPhone 15 has a feature that limits battery to just 80% to prolong the life of the battery. I thought this was bad practice years ago, has this changed? If so, can we adapt it to renewable energy?

odimbannamdi:


Very good point here. The inbuilt charging function of inverters undercharges batteries most time. I have used a 1kva 12v Brighton inverter and a 24v Luminous inverter before to charge batteries. On all occasions, i had the usual small voltmeter attached to the batteries.

For batteries whose absorb voltages were 14.5-14.9v, these inverters never charged them beyond 13.0v after which it indicates as being full the stopped charging and I kept wondering why I was having low backup time from my batteries at the time.

Until someone from here advised I get an external charger and that resolved it. My batteries now hit 14.6v and float easily.

Inverter Warranties are they real?
I remember my first purchases with excitement, I was finally going to install solar inverters branded with my name.
It was a disaster of epic proportions. The inverters failed on installation and the supplier blamed us for connecting the inverter to a large generator. Totally BS answer. This was Tanfon Lily. Then we did Yiyen and my rep and the company stopped answering messages and email, when we tried to file a warranty claim.
Another supplier told me that they would send me replacement parts whenever I placed another order.
I have detailed my experiences in this video of the good, the bad and the ugly. Please share yours and comment on mine. Thank you. Victron Energy SolaX Power Schneider Electric Solar LuxpowerTek Deye Inverter

Hello guys and good evening. Pleasei just installed my felicity CC and i'm having trouble connecting it to the inverter. I'm using a normal network cable and I've tried both the RS-232 and the RS-485 port on the inverter but it just flashes for 10 seconds and goes off. Please how can i go about this as i dont want to overcharge this battery if both AC and panel is available?
Inverter is IVPS3524
Charge controller is SCCM8048

Thanks

If your total load is less than 1000w 12v system is bae. 173A LifePO4 is roughly 320k if am correct o.

TechGeek777:


You are not, the last time @valto posted it was 400k.

Abi price don come down?

dollarnaira:

80k each without bms.

it's HARDly efficient, charging a battery using an inverter. Often, I suggest getting an external charger. And for very large battery banks, it's even much more difficult, relying on the inverter, no matter how much you bought it inverter.

and now, it's much more efficient, and cheaper, kukuma getting solar panel(s) to handle the charging

incogni2o:


Its likely due to.you using an.hybrid inverter.

A Blue Carbon battery I installed have also been drained about 3 times now.

I think its a bit lazy for the company to.allow the battery go so low before triggering it off

Inverter charges it via generator and it comes up back.

Get a non hybrid inverter to charge it.

its under warranty though, I could assist you how to return it to be checked

You thief, did you go and measure it? Was it not the shop that sent it to me directly? Nor be middle man you be?

Fucking hungry reseller

I have been away from this thread for only two days and a lot has gone down.

My problem with most Nigerian vendors is that they treat customers the same way bus conductors treat passengers. They only value one when you're outside their buses, once you enter and money changes hands, they treat you like trash.

When I have the time, I will share my experience dealing with vendors on this thread.

Hello everyone... is a 40amps Ac charging current too much for 48v 200ah (four 200ahs battery connected in series)..

Jefferyzz:
Check ur battery for the c rating. 40a is just 0.2c for 200a n would b ok for most battery. Other might b lower than this eg 0.15 n 0.1

Pls, does anyone Has the main board for Growatt 5KVA inverter SPF5000ES. Or anywhere I can repair the inverter, the problem is Fault 08 " High DC Bus voltage"

kristien4:
its written @c20 rating. Then recommended maximum charging is 10% of battery capacity. I was thinking since its four battery connected in series 40amps should be okay... but i noticed a low bubbling sound while charging the 4 batteries(tubular)at 40amps current. Is it normal?

A friend went to a warehouse in the USA to pick batteries he bought @ batteryhookup and was amazed at shipment destined to Naija. Our people are doing well

C20 - 200ah/20 - 10A discharge..
10% max charge - 20A Charge....

4 batteries in series - 48V, 200AH. Max charge 20A. Discharge 10A

4 batteries in Parallel - 12V, 800AH. Max charge 80A. Discharge 40A
