I have 2 Growatt 5000 ES installed in Parallel with 2 x Blue Carbon 48V 200Ah Lithium Battery Pack For Solar Home System. PVs are Mono 10 x 550W. 5 panels each in series to each Inverter. Priority is set to Solar, Utility and Battery.
We have quite frequent power cuts that results in Batteries charged to 50%. On resumption of Utility power - Battery is pulling like 2KW for Bulk charging which is resulting in Low Voltage in the rest of the house. Like in the range of 205 - 210. Once battery reaches Float charge Voltage output returns to normal.
This low voltage output does not happen under normal operation. PV, Utility or Battery only.
There are 2 related settings:
Setting 11 - Maximum Utility Charging Current set to 30A (Range is 0 - 80A)
Setting 2 - Maximum Ac Charge Current. This is a combination of Solar and Utility. This is also set to 30 A! The range is 10 - 100A.
Maximum Ac Charge Current is set to 30A. Should this be increased?
Or is there something else going on?
