[RE-wrenches] Low output

[Dana]

Try another brand of CC? 

I have had same issue /different manufacturer and had dead out of the box replacement & same issue with the replacement.

Are there any adjustable potentiometers, I do not know this CC? 

I have recently had 2 trouble shoots [with old C-40s] that were low CC output & moved the pots higher & lower and voila the CC worked again.   Very frustrating to say the least.

Off-gridders,

 

            Small 24 volt off-grid install.....new installation, 3, 285 watt PVs in series, 4, L-16's in series, Midnight "Kid" CC.  Problem: I cannot get more than about 200 watts (8-9 amps battery side) out of the Kid display in full noon sun, clean PVs. Should be 700 watts plus and about 28 amps.  Bulk/Absorb set at 29V, battery voltage at ~25 V (pulled down with a heat gun).  I changed that Kid out for another new one> Same issue!  I disconnected the PV wires where they land in the Kid and got

9.3 amps short circuit, 105 volts oc  Called Midnight tech support but we couldn't come up with a good solution.  Ideas?

 

Thx,

 

Bill
