I've got those 2 new panels installed on a ground mount.

http://ecorenovator.org/forum/solar-...0-project.html

And now it seems like I may have found some batteries that aren't too expensive.
They are Duralast 27DP-DL 115 AH Marine batteries. They have some good reviews
from boaters and RV folks.

However, I have still not made up my mine on the C40.. I checked the panels today
at half and full loads and it looks like my PV is 57.2v under full load (400w) and
64v under 1/2 load (200w). 69.3v open..

If the C40 would work with at these voltages, I wonder if it would be marginal.?
