I sold my Seplos bms now using JK BMS in lead acid mode been working great now for months

update I have fixed my batteries, I have made two small packs of 3 in Parallel and 14 in series and Now have two BMS making a total of 30 Kw, The JK BMS works very well at balancing the batteries, Now the issue im facing is the inverter can't charge within the 4 hour off peak time, I am looking...

Still having issues with the batteries not using full capacity, I've reduced the pack size to 15kw with only the best batteries that are all balanced with each other but it still only using 10kw.

I have DC power supply would that work?

Definitely these to packs draining quicker than the rest, so system shuts down early.

What type of charger is can I use, to bench charge the batteries?

This is picture of voltages when system turns off about 12.5kw, system is about 26kw

SOC is suddenly dropping from e.g 70% to 2% voltage still 49.81v

Look below

On the Growatt Spec sheet 45 Amps is max output for Growatt GBLI5001.

I have a solis inverter with REC BMS communication on COM port works but I'm having issues with SOC

I think the Solis Inverter is much better at controlling the charging of the battery it's quick to respond to change in weather conditions.

Got my REC BMS all settup up but having an issue that the SOC drops suddenly for example it's 50% then drops to 3% and then inverter starts charging again.

anyone have battery modules for the growatt packs?

I checked again today voltage was 3v, maybe its sorted itself out lets see.

Did you fix Was you able to fix this one?

that is great news, we'll done

This one I've already replaced with good working ones.

the one pack was down to 0.80 volts today.

alsl one pack seems to get very low voltage compared to others

Yes I mean it discharges 14kw from fully charged battery, I've still only got 14s at the moment

Sounds complicated Hope you get it fixed, I'm still having issues with battery not draining fully stopping at 14kw, I've ordered a REC BMS but coming from Germany. Has anyone got any experience with Solis Inverter and REC BMS?

I have rewired Bms wires now getting 44v.

I have little to no voltage on Seplos bms, checking with a multimeter after adding additional cables im getting 50.44v, I've checked all wires to Seplos BMS are in the correct place but still nothing.

It 14s already there is more battery on next shelve.

Okay I will add the extra wires later today

When I test the pack with multimeter I get 41v, pack isn't fully charged.

Hi Everyone I've been building a large pack out of 5 growatt batteries, I have reconfigured all the batteries to 5 in Parallel and 14 in Series, I've connected it to a Seplos BMS, I've got this connected to a Solis 5G Inverter the CAN communication is Working. Issue I'm facing is that the BMS...

Then set as pylontech tech according to seplos instructions

This is canbus wiring for solis inverter and seplos bms

Hi Tim I bought a Seplos BMS, I have read on other forum that a guy has used it with the Pylontech configuration on Solis Inverter, I am still building my battery need to reconfigure the batteries to 5 modules in Parallel and then into series. I really need some help reconfiguring them to get...

Are you looking to sell the battery?

Hi Everyone I have five Growatt GBLI 5001 that i want to connect together to make one big battery of 24kw, all batteries are working and charging. i think i need to remove the current BMS and install another. I have a 6kw Solis 5g Hybrid Inverter that i would like to use what BMS would...

Hi What was the solution did you get a new BMS working, Ive got 5 of these GBLI 5001 that i want to make one big pack with.
