Added GoodWe Charger PV 4 to 8 and changed/added calculation of power

[Bockhorn-IT]

Added GoodWe Charger PV 4 to 8 and changed/added calculation of power instead of reading the power from register. For PV strings greater than number 4 there are no registers for the power, only for current and voltage, so we calculate them all instead.

Hi @Bockhorn-IT, nice to hear that this is working in your system.

Initially, we had nearly the same implementation, but our problem was that the GoodWe had inaccurate current values for each string. While measuring, a lot of test systems, we had total different current values even if the Nr. of Modules and the cardinal direction was the same, especially with low power. It would also be interesting to know what firmware your inverter has.
