I am closely looking to the behaviour of this BMS but not sure to fully understand. Please look to the chart taken in the period 17.00 - 20.30 (no PV input at all) I have the folloing values: - 47% SOC 48.6V - 35.1% SOC 48.5V Isn't strange?

Wow magic: Mr Growatt, directly from China, increased my inverter output power to 5Kw The change was even much easier than I though: no jumpers to move, no mainboard modification, just a simple input from remote! and this should tell us a lot about industrializzation of (apparently) different...

ok, I finally completed the procedure. Cells V was around 3.550 at the end of the procedure (+/- 20mv) when I reconfigured the inverter to BMS mode (100%), the battery pack showed a voltage of 50.9 that seems a little bit low. Let's see in the next days how it will work. Thank you so much for...

good, we have a beautiful sunny day here in Piedmont - Italy - today, so the battery are charging flawlessly After reaching and checking the corret balance at 3450mV, I can set the values at 54.7/54.6 untill fully charged. Then shall I reset the bms button? Is it a specific procedure/time for...

Here there are the single cells details; they refer to a single battery, the other one shows similar values

ok, but since the BMS SOC level seems to drive the Growatt charger, do you believe I should change the setting from LI to user 2 and then manually set the charging tension to 54.75V?

well... for sure I paid for a SPF5000ES unit... I was hoping that internal architecture of the unit was similar (as happens in many products) and the different output was just a matter of some bridge points to be set somewhere on the main board

Thank you for your reply. When (supposedly) fully charged the BMS never reches the 50V... again: from fully charged to zero I am far from removing 200Ah of power

Hi, I installed a new Growatt SPF5000ES inverter then I discovererd that the rated ourput AC power is 3.500Wh, instead the supposed 5.000Wh. Tried to get in touch with Growatt but no luck..

Hi, my Growatt SPF5000ES shuts down (error 04, lo battery voltage) with 2 200Ah Rosen batteries showing positive SOC but very low voltage. I tried to reset the batteries pushing the BMS reset switch but no luck.. The dischaging seems to proceed normally then, suddenly, the battery voltage drops...
