Smartsolar stop charging batteries in Offgrid-situation

Q&A and troubleshooting

Hi,

I use

  • 2x Multiplus II 48/3000 (L1+L2)
  • 4x Pylontech US3000
  • 2x Smartsolar 150/45

with an ESS-configuration according to Victron & Pylontech UP2500, US2000, US3000, US2000C, US3000C, US5000, US5000B, UF5000, Pelio-L, UP5000, Phantom-S, Force-L1 & L2 [Victron Energy] .

All works fine in On-Grid-situation, but when I turn off grid or switch off the Multis, the Smartsolars stop charging the batteries.

Of course I don’t want this behaviour.
Can anybody explain/help?

Regards

Alex

Perhaps, I found the reason for this myself.

I set DVCC > Max Charge current to 0A.
This setting seems to be overruled if the Multis are on and grid is available. Although 0A are set, the batteries are charged according the current requested by the batteries. When grid is lost, the Max Charge current is applied.

Can anybody confirm?
