Setting charge current of Go-eCharger based on photovoltaik output

You can easily define rules to charge with PV power alone. Here is a simple sample how such a rule could look like:

rule "Set max amps for PV charging"
when
    Item availablePVCurrent received update
then
    logInfo("Amps available: ", receivedCommand.state)
    MaxAmpere.sendCommand(receivedCommand.state)
end

You can also define more advanced rules if you have multiple cars that charge with a different amount of phases. For example if your car charges on one phase only, you can set maxAmps to output of PV power, if your car charges on two phases you can set maxAmps to pv output / 2, and for 3 phases pv output / 3. In general the calculation would be ´maxAmps = pvOutput / phases`.
