Load Current

I have two Vectron MPPT 100-50 controllers connected to 1000 watts of solar and then to four 12 volt 170 ah lithium batteries.

When the controller goes into float mode it does not seem to be able to supply the existing load current. I still have plenty of solar power, but the batteries start to discharge for some reason. After an hour or two they are down to around 98%.

Thanks

@Desert Rat

Check your rebulk offset on the mppts.

Have you edited a Lithium profile preset when programmed for your batteries?

You say you have two Victron 100/50 connected to 1000W of solar. Please confirm that these controllers are connected to two separate arrays totalling 1000W and not connected to the same 1000W array.


Each MPPT must have its own array.
