[RE-wrenches] unusual module

[Kent Osterberg]

Nathan,

There are no jumpers, each j-box has a single terminal. It has 4" square 
multi-crystalline cells, a 2" bronze colored frame, and measures 17.5" x 
42"; just a little smaller than a MSX-60.

I have a dozen Solec modules that were either 12 or 24 volt nominal output.It has been a long time since I was in the J boxes but it seems like they may have looked as you are describing although there is only one J box.

It is a little smaller than a MSX-60. It has 40 cells that are wired in four parallel strings of ten. Open circuit voltage is about 6 volts. Shorted it put out 4 amps in bright but very overcast conditions. I suspect that it would put out 8 to 10 amps at STC. There are two j-boxes, one on each end, with very substantial terminals. It still operates, but obviously it isn't much use for charging a battery, even a six volt one. Anyone familiar with a low-voltage high-current Solarex module.
