This is weird. We have a four-month-old Multiplus 24/3000/70 that has recently been reporting false SOC numbers and shutting down at 50% even when the charge controllers are floating. If you flip the rocker switch On to Charge Only back to On it agrees with the controllers.
Also, in cases where the generator does need to come on (e.g., at 50% charge), the Multiplus sees it, but goes into float mode. It doesn’t change to bulk charge unless you flip the rocker switch from “On” to “Charge Only” and then back to “On.” The firmware version is 465.
Any thoughts?
