Voltage drop musings [RE-wrenches]

[Bob-O Schultze, Electron Connection]

I agree here with Windy, The SB3048 works great! However, be aware 
that it is limited to 30A OUTPUT at either 48 or 24V. I've found that 
for most systems, 30A @ 24V just doesn't quite cut it. I've been on 
the phone many times to Rick & Melanie at RV Power Products to 
encourage them to kick that out to 50A when in the 48 to 24V mode, 
but apparently there are technical challenges to overcome. The good 
news is that they have been as responsive as we'll like ALL our 
suppliers to be in trying to improve the product. Ya gotta love that.

>Here's another possible fix -- If the system is 24V, Use a Solar 
>Boost 4830 controller which gives option of 48V in and 24V out. You 
>can wire the array for 48V to charge 24V batt.

>Likewise, Solar Boost 50 can take 24V in and drop it to 12V battery.

>You can get away with 1/4 the size wire for equivalent power loss.
