Bogart charging LiFePo Ray,
Even after draining the battery down by 65 amps I still was getting the roller coaster charging amps. I sent a quick email to Bogart and they called me back within an hour and had me change the P1 and P8. He said that the charging volts and the max volts have to be further apart so that the system doesn't perform like what I was seeing. He said the system was hitting max volts for an instant causing the decrease in amps - then system would see lower volts and send max amps again in cyclic manner. So now I have 14.4 P1 and 15.0 P8 and the charging amps are a steady high level.
The front range, Denver area, is prepping for possible "bomb cyclone" of up to 50 to 60 inches of snow between Friday and Sunday. Here on the western slope we are only expecting 6-12 inches so probably will not see whole lot of solar charging in next few days.
