Your system is incorrectly wired. All negative current into and out of the battery must flow through the BMS. You are seeing charge current on the Victron charger because its connected directly to the battery most negative cell. Regard the cells and the BMS as the 'battery'. Remove all cable...

It seems that it's not a genuine Blue sea fuse holder, Blue sea, Low cost copy,

Assuming it's a 16 cell battery, bulk at 54v, 3.375 volts per cell, is perhaps too low to fully charge, ( unless there is a very long absorption period), thus the battery is still taking power under float volts, 3.281 volts per cell. My bad, it seems it could be a 15 cell battery.

The specification suggests a BMS is installed in the battery. I cannot see that a company would sell a lithium battery without a BMS. Example of battery balancer, https://www.ebay.com/itm/175874775173 https://www.ebay.com/itm/235361478930 Example of shunt, ( BMV 712 has programmable relay...

Your 4 off 12v 230Ah batteries store around 12000 watt hours of energy. Maximum current output delivery 200 amps. The current maximum for similar batteries in series is the same as a single battery. A 5000 watt inverter in a 48 volts lithium system will pull 100 amps at full power, add 10% for...

Current limit is poor on these units, will fold back or fail. This is only under reversed polarity of the solar input, not under correct connection conditions. Suggest you install a 24v Victron Blue Smart IP 65 charger direct on the battery. A better engineering solution.

A 120 amp alternator is delivering around 80 amps at idle speed. When all vehicle 12 volt systems are loading the alternator, cooling fans, lights, perhaps 30 to 40 amps are needed. The Victron Orion 12 12 30 is not very efficient, typically taking 35 amps from the alternator. It also runs...

No, can you identify which batteries need this? I guess it's a limited low current stage at absorbtion volts.

The DC input on the powerstation is used for DC power or solar panel, 11 to 28 volts, 120 watts, 10 amps. Connect your panel directly not via a external controller. The unit has an internal controller that accepts panel directly.

There is a tollerence on the panel specification, your new panels are generating a higher Voc. From the Epever manual for the 60A 150 volt unit,

Eight 108Ah batteries in parallel idealy need a higher charging current than the maximum of 20 A via the PWM controller. The generator at 60 amps is better and may be needed to bring the batteries to full absorbtion state. There could be issues with the batteries not being fully charged thus...

This may happen with low cost PWM controllers like the unit provided with your kit. More advanced controllers are usually protected against panel disconnect. In fact the Victron range of controllers happily operate without battery connection. ( once initially powered with a battery to...

Usually AGM needs a higher charge voltage than GEL , default for the 3210 on the GEL setting is 14.2 boost volts. Either change to USER and set a 14.6 boost volts or change back to sealed settings. Check load output is switched on, manual page 19,20. Possible faulty interconnection...
