upgrading power converter
My power converter has apparently bit the dust, lights flickering for past couple of years now no charge to batteries... Anyhoo, we do a lot of dry camping, where we need to daily boost the batteries...

OK,
Small scale here.... A T1275 Trojan. Rated 150 AH... at 50% SOC, paired with a PD9245, with 6 feet of 8 gauge wire to the lugs on the battery terminal.
Who here would care to estimate charging time to a 90% SOC, or time it takes to get to 14.4V and bump the wizard out of bulk mode and into absorption mode, and time to put the battery instead on a 120W 7 Amp PWM bulk 15.0V portable solar panel?
Should I go to a heavier gauge wire from the PD 9245 to the battery? Voltage loss?
OK but first of all, did you get another T-1275 that works? ISTR you got one or two used ones for free but they were duds.
also can't answer any of those questions without knowing what amps you get at first starting at 50%. After that it is easy--it is all in the ugly graph. Everything is proportional so just use 150 instead of 220
