rbertalotto Posted February 15, 2017 Report Share Posted February 15, 2017 I have three 140w panels on the roof with a Bogart SC-2030 charge controller and a Trimetric monitor. Left the camper to go four wheeling and returned to see the batteries (Two group 31 AGM) charging at 17.5 volts! I disconnected the solar panels and the house converter was working fine and charging at 13.5 Trimetric showed 100% charge HELP! Although this week I'm in a campground with shore power, all next week I'm in Phoenix boondocking. I need my solar! I tried to call Bogart and an answering machine said they are not taking calls today and to leave an email and they will get back to me in 24 hours! Great customer service.....

dewilso Posted February 16, 2017 Report Share Posted February 16, 2017 Must be something in the air. My BIL has a Morningstar that is wanting to charge a 15 v, it's set at 14.4v. Have you checked you equalize settings ? Dave W. KE5GOH Stuck in the 70's --- In E. Texas Link to comment Share on other sites More sharing options...
MrSeas Posted February 16, 2017 Report Share Posted February 16, 2017 Are you sure your batteries are actually charging at 17.5 volts? Or is that what your solar panels are supplying to the controller? Link to comment Share on other sites More sharing options...
rbertalotto Posted February 16, 2017 Author Report Share Posted February 16, 2017 Are you sure your batteries are actually charging at 17.5 volts? Or is that what your solar panels are supplying to the controller? This is the voltage I'm reading on a couple of independent volt meters I have around the camper. My 12v televisions would not turn on as the voltage was too high. UPDATE: I disconnected the solar panels for 15 minutes and then reconnected. Everything went back to normal. Charge voltage at 13.7v. Not sure if this was because the sun was setting and the panels were simply outputting less. Tomorrow we'll see what happens.....

rbertalotto Posted February 16, 2017 Author Report Share Posted February 16, 2017 I reprogrammed everything to Program #18 and everything seems to be working fine now. Voltage went up to 14.5 and then leveled off at 13.4 and this is where it is staying. One question...the temp reads 66.c What does this mean. It can't be 66 degrees centigrade, that is something like 155 degrees F. Batteries are not even warm. In fact, they are cool. About 50 degrees F.

Yarome Posted February 17, 2017 Report Share Posted February 17, 2017 I reprogrammed everything to Program #18 and everything seems to be working fine now. Just read this today and glad all is well. I would imagine it was the default "top off" charge setting. The 2030 is a little unique in that they have a bulk, absorption, float, AND "top off" charge cycle. An overvoltage to "push" just one last little bit of juice once the batteries actually "read" 100%. It can be set by a set voltage.. (I think it is something like 10-64v's) or as a percentage (100%-120%?) One thing that is great about their controller is the complete user control-ability. For your G31 AGM's, I might suggest tweaking your settings to 14.8 and 13.6-13.8 respectively. I wouldn't set the top off any higher than 15, but then again.. I don't know that I agree that it's necessary, or advisable to run a top off charge on AGM's. Link to comment Share on other sites More sharing options...
rbertalotto Posted February 17, 2017 Author Report Share Posted February 17, 2017 I still need to figure out how to reset individual parameters. This might be a good system, but the instructions and how you modify the settings is very complicated. I agree with another poster, a nice LapTop user interface would be fantastic! I'm going to leave it alone for now as I need this solar system next week when I'm off the grid for over a week. I'll mess with it more when I get home. Thanks for all the input!

Yarome Posted February 17, 2017 Report Share Posted February 17, 2017 Advanced user settings for individual settings is only available if you set your P7 setting to L3 or L4. Then you'll be able to set each individual value all the way down the line. On edit: I should say.. the higher the level setting, the more values will be available to you for customization.
