Just some feedback. At the end all is working well. The 300W sticker on panel showing Voc=21V is a miss print and should have been 41V.

Using 2Sx650W and 2Sx300W and then in parallel sorted it out.

Thank you for everybody's advice. I have decided to use only the 2 X 650w pannels on my inverter. Appreciated

Good idea to buy a solar charge controller on it's own and then add your 2 x 300w panels to that input. Controllers are quite cheap and the more solar you can harness the better in low light times.

Glad you got it all working.

After all the experiments and getting it to work, you went back to a lower spec. How come?

As I understand what I was trying to do with the two different watt solar panels. Can be explained like for instance you take a 9 volt battery and connect it with a 12 volt battery just to get mote power. You can't do it. As for 1 of the batteries wil be damaged. 

 

Thats how I understand it. 

 

Anycase the 2 off 650 watt solar pannels is sufficient to power my house on a synny day. . . And in deu time I  will be adding more 650w solar pannels. Need 8 of them.
