Thanks! You have the newer model SW3000 (815-3012). Mine is an 815-3000.
It is looking like in the early 815-3000 versions there is a custom battery type that could be set by the dealer (or factory) thus OEM Preset.
It may be that somewhere in the 815-3000 production the OEM Preset morphed into a user settable set of parameters.
Then out came the 815-3012.
Anybody know how to set the OEM preset values on the 815-3000 ?
In the mean time if I set my unit to AGM
battery type I can charge my LiFePO4
bank. There is a bit of a trick....
My unit lets you set the man percentage charge current
. The default is 100% and at that the unit attempts to go to 14.4 volts and current
limits to 130 amps or so.
Monitoring the actual pack voltage I can shut the charger off at 13.9 volts. Of course this does not get the pack full. The knee is too abrupt at that charge rate.
I've been using 100% current and at pack voltage 13.6 change the % current to 50% which drops the current to 50 or 60 amps. Then when the pack voltage gets to 13.7 I drop the current limit to 20% which is about 25 amps and stop charging
at 13.8-13.9 volts.
