question

Mike Casey asked Mar 29, '22

BYD LVL 15.4 (120kWh) - I want to increase rate of charge and discharge

Right now I have the following setup

CVL 58.4V
CCL 1944A
DCL 1994A

However when I set grid point to 100kW or -100kW the most the batteries seem to want to take and give is around 60kW.

Im just wondering if I am missing something, as with those figures I would be expecting well over 110kW i/o

Thanks,

Mike

Hi Mike,

There are several other factors that might influence how much power you are able to charge and discharge.

Some other factors that need to be considered:

What inverters are you using?

The accounting for the kVA to kW differential, and temperature (these are listed in the inverter spec sheet)

The AC input current limit

The grid voltage

100 kW is a significant amount of power, It would be a good idea to discuss this directly with the Victron agent who sold you the system. There may be other limitations as well.
