I believe I mentioned several examples of several quality MFG
But 'if' mosfets that handle 25~30 amps can be installed in a $30 controller...
Surely somebody can make something comparable to the $200~$300 controllers for less, and rate it correctly
Looking at the cheap controllers it seems the major thing visibly missing is a quality heat sink
They have no trouble including LCD displays, but they don't include heat sinking fins and current limiting SO you can use enough panels to actually reach the listed output rating
So to find a spare that will handle the 35 amps peak I expect to see someday, (depending on conditions) I'll have to buy one rated at 50 or 60 amps
My Xantrex is a true 40 amp controller, that will handle 60 amp input
A replacement is $200, just may have to go that route, OR maybe a Tracer,
