Just a question? Can you install electrical equipment so close to water pipes.

@TaliaB 100% correct, the BMS regardless of been in voltage mode or communication mode will always protect the cell from going overvoltage. And as you said no use going over 3.5 V max charge and rest at 3.2 V, the proof is that my battery 4 1/2 yeas old over 2600 Cycles still show 100% health and charge to 102 AH of rated 105 AH

@Scorp007 @frivan To me it makes no sense charging the batteries to full cell voltage all the time. Why stress the battery for just a couple of AH. My battery is rated 56 V so individual cell should be charged to 3.5 V. That is exactly what I do. And the cells get to equalizing value. See dashboards.

No, it's a Seplos BMS.

@Stefan Cornelissen As you can see from the attached dashboard, the battery still charges to 98% soc, 101Ah. That is because the battery is set to 55 V if I set it to 56 V I can get it to 99% 103 AH I don't want to do that no need to stress the battery for an extra 2 AH Just now.

I've read here numerous complains about other battery suppliers using all kind of excuses not to repair batteries under guaranty. KUDUS to LBSA. My 5.1 KWH battery is 4 and 1/2 years old 2160 cycles. Last week I had three random trips. First one when battery was supplying just over 40 Amps to the house load. Second one when I changed the set up on my inverters from SUB to SBU. Third trip just tripped could not see the reason. Contacted LBSA technical department, was told to bring the battery over. Took battery over, I was told to wait a while they test the battery. They found a faulty BMS and one Led. Replaced the BMS and the faulty led as well as the battery breaker, also they added the earth connection. Three hours later I was on my way home with basically a brand-new battery. All done under guarantee. My sincere gratitude to NIVÉ TIETZ she really demonstrated the significance of excellent customer care. I would like to stress all done under guarantee. See attached dashboards.

In my area this month has been very poor, lots of cloudy and rainy days. it's been the lowest production since installation 4 years ago. Here is my dashboard for this month. Previous month.

Set 19 Bulk charge voltage to 100% I my case I run my system on voltage settings ((setting 5 on USE mode) I charge my battery 16 cells to 56 V, float at 53 V see attached

@Denns That is exactly how I run my system, setting 14 is on OSO, setting 12 (switch over to Grid) set at 51 V that is +_ 25% of my battery SOC. One has to cater for the inverter "no load loss" in my case two inverters is +_ 1,8 Amps from the battery. I'm at home, depending on Wheater conditions, I will change settings when need. Also, I have a custom-made monitoring system where I can see basically everything on my system. as an example, the last two days.

In my case I run my system on SBU, also my battery does not last through the night, I have my voltage setting (12) set to switch over to grid once SOC gets to 20%. so, I make sure that every day I at least use about 80% of my battery.

If don't want to use grid to charge the battery, change setting 14 to OSO (only solar)

Yes, only one battery. The cable you see connected is for my custom-made monitoring system. Using voltage level in the inverter to control battery parameters. Been running like this for 4 years now. Could not get BMS and the two Growatt inverters to work. One of the cells, cell number 2 never gets to full charge, it's been like that from day one.

Andries, I have a question. I have 4 years old LBSA battery 5.1 KWH, 51.2 V, 100 AH What make BMS is installed in this battery. I was told is Seplos BMS. Please confirm.

I have the same issue with one of my battery cells, it's been like that since day one. Cell number two. However, it has not deteriorated over time. I can still charge it every day to 102 A/H, rated 105 A/H Battery is almost 4 years old and has 1927 Cycles. Make LBSA.
