I have the following setup with AC coupled on input and output (see below), with blue components genuine Victron parts.
Inverter 1 output is measured with a victron AC current sensor, which is coupled to the Aux1 input of the multiplus. The VRM portal detects correctly how much power inverter1 is generating through the use of the AC current sensor.
But the multiplus does not use the available inverter 1 power for charging the battery. Only inverter 2 power is used, which is AC out coupled.
Also, when the grid is enabled, the multiplus is configured as pass-through, even though in the venus image I configured it as self consumption.
To summarise; I want
- all inverter 1 + 2 power to be used for powering the loads
- all remaining inverter 1 + 2 power to be charging the battery together.
- use as much inverter 2 power as is offered on the AC out, and take the rest from inverter 1 on the AC1 input.
- the multiplus not to use any grid supplied power at all for load powering or charging; only use as much as the current sensor is measuring from inverter 1
