can you parallel the cheap chinese MPPT controllers? i know they are not really MPPT but appear to do something. as winter is getting close i am not getting a lot out of my panels at the moment so thought i might try one of the cheap ones. i cant afford a "proper" controller like a tri star mppt at the moment, but as my ts45 have just died i will need to replace it sometime. i am not using the wind turbine as i still need to fix it so am relying on solar and genny back up. if i get as really good day of full sun i may get 15 amps if i am lucky but unlikely to get more than 10 amps. rather than run a 10 amp one near its maximum i though get 2 15 amp ones and parallel them? by that i mean feed 3 of my 5 panels into one and the other 2 panels into the other one, and connect them both the battery bank. if that makes sense. i have a 5 core cable from the panels so no problem splitting them.
