Does anyone have any idea how I can achieve in NodeRED (or via Modbus) that charging the battery from the MPPT regulators is disabled, but the full power is still sent to the grid? In other systems, this is called Feed-in Priority. That means, after covering the entire household consumption, all surplus energy should be fed into the grid. By limiting the charging current through DVCC, I can only achieve that the Multipluses do not charge the batteries from the AC coupled inverter, but I haven’t found any setting to do the same with the MPPT tracker. Would it be possible to handle this via DynamicESS in NodeRED? Just this one function, nothing else is needed.
Example: In the attached screenshot, you can see that I have set DVCC to 0. Any production from the AC coupled inverters (one on the input, another on the output) exceeding the house consumption goes into the grid. But the MPPT (PV Charger) still charges the battery with the produced power (~3300W). I need the Multipluses to increase their feed-in power to the grid by that amount instead. So, zero energy should go into the battery.
