results of solar install

I installed Three 100w ronogy (amazon) solar panels on my 990 with Bogart Tri-meter and bogart solar controller.

first test run the system is working great.

last 2 night we ran TV and Satellite system for around 4 hours (listening to Sirius radio over the satellite TV receiver). Fantastic fan runs 24 hours per day. tonight I think a Phillies game might be on the schedule. I think this combo is running around 11amp load.

When I got up this morning Bogart showed me I had 73% battery left.
by lunchtime it was back to 98% and showing almost 15V as the finishing touches were but on batteries. This is Two 90Ah AGM's.

I really would like to put a load test on this thing. by the time I am in "peak sun" I am already almost charged. I have seen 14a on the solar charge screen once when I checked around 9:30 this morning.

mid 80's in day, mid 60's at night. no need for Generator.

This is also the first time towing the S10 with a blue ox tow bar that came with it. worked great. That red tank under front tire is for my extended run kit for the Honda2000. that water tank laying behind RV is to deliver drinking water to the RV.
  • Nice glad it's working out for you it seems you get to run alot with 2-90 AMP Hr batteries

    I also have the Renogy panels 2-100 AMP and the largest Lifeline AGM Battery 12volt, 125 amp hour

    I'm usually up to full charge by 11am
  • Very good. I've never heard the term 'control voltage.'

    Here is a link to my actual batteries.

    you see on this sheet: change method for cycle use (repeating use)says current less than 27A, and a control voltage is 14.8.

    than once it meets Bogarts definition of charge (I am using profile 4 which is harder to meet than profile 3) it will drop back to 13.8v for maintain.

    On the Bogart I am using my own profile based on this info.

    Always willing to hear any advice that helps me keep these batteries lasting longer.


    Oh ok, I see. Thanks for posting that

    Is 15 volts sort of high for an AGM battery?
    Absorb is around 14.3, so yeah, almost 15 is too high.
  • Bogart is a good way to go. Is 15 volts sort of high for an AGM battery?

    What profile are you using?
