Cool - just know that they have now gone in cyclic service - and as even the manual shows, they need to be returned to 100% SOC at least every 10 days. And for AGM's, whether big or small, that means a LONG time in float AFTER absorb has finished. At least 8-10 hours or more or you'll be walking them down in capacity with hard sulfation.
Hard to do with just solar psoc. So once in awhile, they need a no-load recharge - like a whole day to themselves while you watch frustratingly low float current pass.
Not realistic? So if you have a source of AC for a charger at least bi-weekly, then use it overnight.
An interesting thought is a "donor" smaller maintenance LFP battery (charged by solar perhaps) just to serve as this bi-weekly float with a dc-dc charger for the agm's. Sure you could do an LFP "add-on", but it still doesn't relieve you from that pesky agm maintenance.
Interesting thought using LFP as a "maintainer" for a large Pb bank once every week or so....
