Progressive Dynamics Power Inverter P9140A

I have a Progressive Dynamics Power Inverter P9140A with the Charge Wizard P9105. The equipment is used in a new Sunny Brook trailer.

Has anybody used this equipment with large 31M, AGM 12v battery?
The voltage levels look pretty good for the commercial AGM battery manufactures, Trojan Crown.

I currently charge with a Honda eu1000i inverter generator and want to retain that capability.

  • The 91 series along w/ the charge wizard is exactly the same as the newer 9200 series. I've used the 9130 and the 9155 both w/ CW. I now have a 9245 on a Honda 1000. Everything works great on LA, but supposedly works great on AGM also.
  • The Charge Wizard is working great. It would be nice to gain a quicker charge time with AGM batteries.

  • You will need a bigger generator & converter to speed up charging.
    I would stay as is with one or two of those batteries.
  • If fast recharging for a lot of dry camping is a concern, than a higher amp output converter may be preferable. If fast charging is not a concern, than what you have should work fine.

    The detail I'm not sure about is if AGM batteries need voltages different than standard deep cell for charging and maintenance.

    First, that is a converter, not an inverter (Which does the inverse of a converter).

    Second, though I have not used it a Group 31 is about 130 amp hours as I recall, times 0.3 (30%) is 39 amps. so the 40 amp converter is the exact size I'd recommend. Should work quite well.

    The Charge wizard is optimized for Flooded wet cells, but most folks tell me it should work well with an AGM.

    Now a fact:

    I have, in this motor home, a Progressive Dynamics 9180 with wizard (80 amps) I have a pair of GC-2 (Interstate U-2200) Golf car batteries, and I added a Pair of MK Group 31 AGM's.

    Then I added some older Grouup 27/29 Maintenance free's I had from other things when I packed up my house.

    The first batteries to go were the AGM's. they were a year newer than the U-2200's and they were the first to go.

    Then the Maintenance free's (The last one replaced just last month).

    They, however, are older than the RV.

    The U-2200's Still doing well. Though they are starting to show their age (8 years plus) and I doubt they will make it to 10.

    Something to consider.. This is part of the reason I do not favor AGM.
