This is a battery based, grid tie system. His equipment is a pair of XW4024s (Schneider – and he has NO interest in replacing his inverters) and three Classic (Midnite) charge controllers. I’m concerned with integrating the LFPs with his old inverter, but his Classics, I believe, can be reprogrammed to accommodate the LFPs. This system was installed around 2015 so the equipment is not new – but it’s basically been humming along until a couple of weeks ago, when there was a week of 60 to 90 MPH winds that killed the power for a while. This is near Boulder, CO (at 9000 ft elevation). His system worked fine til his old AGMs gave out. Their power was out for ~3 days, then came on for 2 days, then went out again for a couple of days. So he realized how undersized and old his batteries were.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If he gets some new LFPs, do you think they’ll work with this vintage equipment? Any of your wonderful advice to pass along!?
