How can I remotely switch my multiplus II between inverter / charger?
I want to be able to do this to charge my batteries at low electricity cost, and only consume from the batteries during high cost. My stumbling block at the moment is just sending a signal to the Multiplus to be in a certain state.
To clarify, I want to be able to do this automatically via a script several times a day - so any manual menu clicking isn't viable.
So to do this I'd need to drive a relay for an aux input to the Venus or Multiplus or similar.
