MultiPlus-II GX in 3x230V network, integrated / controlled with Arduino ESP32

[chrigu]

You could recalculate the measurements to suit a 3x400V/230V grid. Voltages are easy, but currents and power is a bit more complicated. You could do this in nodered, then use a virtual gridmeter with the corrected figures instead

Wrong measurements

Delta configs are not supported by victron, so i personally would not keep selling systems for delta grid setups. A possible solution could be to recalculate the measured values to match 230/400V wye and sending that through a virtual grid device in nodered. So for example, the the measured phase voltage between L1 and L2 (which are connected to the MPs L and N input) could be passed straight to the virtual device as the L1 voltage. Thats the easy part. The complicated part is the power, sin…
