I have noticed lately that if "Optimised with battery life" is enabled, and the doc limit is set to 80% for instance and the batteries is at 50%, the MPPT throttle output to match only the max charge current and the source the load power from the grid. As soon as I lower the limit to 50% or below, the MPPT throttle up, and charge the batteries with the same power as before as well as the loads. Am I missing a setting somewhere? I have played around with "without battery life" and this do not change anything.
