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 around 42.9V and inverter shuts down.
(see pic's)
As far i undertand the Rosen battery is arranged in 15S4P cells configuration and equipped with a Seplos BMS
