outboundwest,
The Magnum running flat out at 125 amps of charging only draws 15 amps. I think that was pretty clever of them--because it means you can charge at full bore on a 15 amp shore power supply.
In real life, I limit mine to 12 amps, because I don't believe in drawing more than 80% for long periods of time. This also limits my charging amps to the maximum my bank can safely accept.
On your bank, fully charged would be when the rate reaches between 8 and 9 amps.
Very helpful. Thanks. In early 2016, Lifeline ran themselves completely out of inventory on the L16 6v. Couldn't get then anywhere in Florida, so I punted and got Fullriver DC 400-6, which offered the same form factor. The bank's location had already been built and planned for, so size was important.
You've been very gracious with your time as this thread has crept from my initial question. I need to do my homework and re-read the literature and get converse in this again. I'm going off my memory from a year ago, and haven't thought about this since.
Because I'm comfortable with math, I recall wanting to run the figures in an excel spreadsheet from PV panel through the system, but there are so many efficiency factors that I recall it was frustrating.
My phantom load is about 2vdc, so I'm assuming if my magnum panel is telling me 6-7 amps charge rate at the end of the process, then that's about 8-9 at the battery, using information I've learned in this thread. Yes, the loads obscure the measurement of voltage - frustrating.
To limit the charger's power input from shore down from 15 to 12, are you just using the shore setting and turning it down?
