Hi!
I have an offgrid system, which consist of:
- 17kW solar
- 22kW Li-ion battery
- SmartShunt
- 2 pcs MPPT 250-100 Ve.Can
- 2 pcs Inverter RS Smart Solar (in parallel)
What happens is, that during day time the MPPT-s keep producing lots of power, which partially is consumed in real time by the imverters and partially is charging the batteries.
However, the inverters are not aware about the fact that the two other MPPT also produce juice, they just calculate how much amps they were consuming from the system. Despite the battery is fully charged they still keep showing 0% SOC (see screenshot).
Very disapponting is the fact that despite the two Inverter RS is called “Smart”, actually they are quite dumb, they can not communicate with the Smart Shunt to sync the real SOC of the battery…
What workaround do you use guys for these situations?
