We have built 12.6kWp array with 30 x trina 420Wp (10.69 Isc and 49.7 Voc).
We want advice on running 2 x 350Voc and 2 x 400Voc paralleled strings to MPPT 450/100. I the manual it states that it can take 'slightly' more with caviat that polarity protection is only good up to 20A!
Elsewhere it states that a max if 7200Wp per tracker which we would be under. We are wanting to max output in low and winter sun, but distributer says it will crop all year round.
I am a bit concerned it will work machine too hard?
