ttbikes Report post Posted June 11, 2020 I installed NorthStar AGM batteries in my Airstream 2006 396XL. I checked to see if the inverter was compatible but not the solar unit. Is this a possible problem? Share this post Link to post Share on other sites
wolfe10 Report post Posted June 11, 2020 That depends on the solar controller. If it has an AGM setting or one close to it (volts in Bulk, Absorption and Float) you are OK. Best advice is to compare those three stage recommendations for your brand batteries VS what is set/what you can set in your controller. Same for reprogramming your inverter/charger.
