ORIGINAL POST BELOW
I have a string of 8 sunpower p17 panels with a Vmp of about 42v (Imp of 8.12a )so total voltage of 336v. The only dc breaker I can find are these ones that cost almost $100 from midnite solar that work with thier rapid shut down system. I assume I would need one of these per string so I would need 4 costing $400?!!?
MNEPV-600RT 16A
MNEPV16-600RT, MNEPV20-600RT

I do not need rapid shut down since panels are not above liveable space (picnic shelter)
is this seriously the only breaker that will work? Was hoping to spend a lot less $$$$.
