Help Please, before I destroy something. I quite new at this solar thing, and I hope I'm just reading this wrong, which wouldn't be unusual. But I just finished installing a Morningstar Ts 45 charge controller and remote meter in my Rv. They're going to be used in regulating my single Solarex MSX 120 solar panel. The solar power will then be feed into 4-6 volt batteries connected to produce 12 volts. Now here's the problem I'm having.
The panel label states: Solarex-MSX 120. Series fuse-20. P. Max-119.7 Voc.- 21.4. ISC-7.91. VP Max-7.11 P Max-85.0 W. IP Max-5.66 A.
The lead from the solar panel is fused with a 20 amp. fuse, and before I put the fuse in and connecting it to the charge controller, I thought I would put my digital volt meter on the lead to check the voltage from the solar panel itself. It read: 21.6 volts. Is that what it should read? I thought it would be a lot lower than that, or am I just reading something wrong?
I wanted to check in with all the experts in this field before I did any thing foolish or stupid, and causing me more grief than I could possibly afford. And any and all help anyone could possibly give me to figuring this whole thing out would be truly appreciated.
Thanks a bunch gang, Crossroads.
