I have a small solar system with buffer battery:
1 x solar cell 410 W
1x SmartSolar MPPT 100/20
1x SamartShunt 500A/50mV
1x Battery 12V 28Ah
1x MultiPlus 12/800/35
Everything is connected to a RaspberryPi with VictronOS via USB cable
2x Ve.Direct to the SmartSolar and SmartShunt
1x Ve.Bus to the MultiPlus
ESS is selected as configuration on the MultiPlus and DC power supply.
Connected on the MultiPlus:
AC input - Grid supply
AC output - continuous load of approx. 200-400W
The following problem has now come up:
When the SmartSolar is connected to the Raspberry, it switches to state: externally controlled and shuts down. If at all 5W - 20W come through. If I disconnect the VD.Direct and restart the SmartSolar, it delivers the full PV power.
Does anyone have an idea?
If desired, I can also provide RemoteDesktop (AnyDesk) if someone wants to look at it.
Many thanks in advance.
I am grateful for any idea! ;)
