Hi everyone.
Our set-up:
Quattro with 400AH, 48VDC lead acid batteries, Smartsolar 250/100 with 4kW PV.
ESS set-up, load is a water pump consuming around 5kW. We set it on Optimized w/ Battery Life. Min SOC @100%, Active SOC 100%.
However, the batteries get discharged and supply the load together with the PV, with the Grid only on standby (only around 100W which was the grid setpoint).
Then when battery SOC reaches around 97%, the Grid supplies the load entirely (passthru) and the PV only charges the battery. When the SOC reaches almost 100% , the PV output is only around 1kW, even though the sun is up and we are expecting a high output from the PV.
The systems remains in this condition, with the grid supplying the load and no PV power supplementing the grid.
We also tried Keep Batteries charged. But still the same. Only the grid supplies the load and the PV only charges the battery. BUt when the SOC is already 100%, the PV output is very minimal and only supplies the battery at float charge.
Hope anybody can give us any idea why this is happening.
