12v battery/ 12./24v MPPT ~ 24v PV Panel
This question troubles the Old and Slow mind. I have a 24v/120w Cynergy PV panel. I would like to use it for duel purpose. For my 24v e/scooter and my 12v RV, not at the same time. The MPPT states (15...

Hi KJ,
I believe Blue Sky for the 3024di says 98% @ 17 volts and 96% @ 30 volts input. I agree that line losses can be significant. My RV came with a #10 prewire. To use it with low losses I chose to go series parallel for the Unisolar panels (system voltage @ 33). That gave me a line loss of under 1%. (dual #12 from panels to combiner box, #10 to the controller, #8 from controller to battery banks).
I believe I'd choose the new Rogue 3048, when the time to add panels comes around. I can't justify it yet, as I keep failing to run out of power. *grin*
I do wish Marc had chosen to do a 6048 Rogue. If he had, I might have "started over" and would aim at 1200 watts of solar.
I'm currently sending 170 watts (13v, 13a) to the battery banks from 256 watts of flat installed panels at 10:30 a.m. local time. I've deliberately forced equalization mode as my house keeper is running an 1100 watt vacuum cleaner. I'll be doing about 45 minutes of driving so that should pump about 15 amp-hours back into the bank.
