Back again. I am in the process of placing 8 of the 190W panels on my eastern roof. Today I mounted the racking and 4 panels in one string, tomorrow I hope to add the other 4. It seemed like a relatively straight forward process.
Questions:
What box do I need to run the two strings into? Is it mounted on the roof, or should I put it under the eaves? A junction box came with the used equipment, it has 2 circuit breakers, one for each pole - I guess it was a single string array as it was grid connect. Can I add 2 more circuit breakers and then combine them in the box before sending to the MPPT controller? The cables supplied are 4mm, but the connectors don't match the panel connections. Are diodes needed anywhere in this set up?
Any advice would be appreciated.
Cheers
