Version 4.1

- Profits: special operation: massive change of sale price for given month (specially for users from Poland)
- Profits: new indicator: 'Self-Consumption'

Version 4.0

- New options for Price<0: 'Disconnect from grid' (Inverter only mode: This is good if you have AC-inverter (AC-coupled PV) connected to AC-Out) and 'Switch off "DC-coupled PV - feed in excess"' (This is good if you have DC-inverter).
- Discharge: program automatically decrease GridSetPoint in such way that batery discharge should last whole hour
- New option in Profit: 'Hour balance' . It should be checked in Poland where Electricity suppliers calcualate bilance of sell and buy energy. If sell&gr;buy then this is sell (value := sell-buy). If buy&gr;sell then this is sell (value:= sell-buy). So never during full hour we have both sell and buy on bill.
