I used this controller very little until I designed my own 48 volt controller for my system. Simple and robust it works exactly as advertised. 12-24-48 volt systems with DC meter. Purchased for $230.00 Will take first offer over $125.00 Contact me here or email at : bruggelog(at)netsync(dot)net We can work something out with shipping or pick up etc. I am located in Western NY.
