Hi David,
it is a 2x100W module...so i have total of 200W.
I was really worried of wiring them up in series, thought that i would exceed the 57V max of the controller.

I will be adding 1 more battery of the same capacity (200AH) but this time i will add 2x72W module, so my new configuration will be 100W&72W in series/parallel. the 72W module specs are : VoC-18V and IsC-4A, would there be any problem with that?
What about blocking diodes, do i need them?

Battery bank will be 24V system...

Thanks

I am just a beginner...
I assembled 2 100W solar panel...specs: VoC- 25V IsC - 4A
I wired these panels in parallel with my solar boost 50DL controller...
I have a 200AH battery bank...
my system voltage is 12V...i am using these set-up to power the lighting requirements of my farm...
My question is, why does the battery voltage drops with the solar panel voltage? do i need to install a blocking diode?
My farm is located in the Philippines...at the moment the weather really is hot, which is caused by el nino phenomenon.
The load at the moment is 720W per day and the battery drops to 11.7V in the morning and the maximum voltage we can achieve at the end of the day is just 12.7V
Any thoughts?
