Hi,
I currently run a system with two MPPT (100/30 & 100/20) and a smartshunt together with 2 gell batteries in a campervan.
A couple of days ago, the smaller MPPT charger stopped working. It might be related to a firmware update, but I do not know if the time correlates.
The PV Voltage appears to be ok for charging, I checked the ones reported with a multimeter, and they are correct.
Interestingly enough, the battery voltage of the 100/20 is quite off from the other devices and is correct if checked on the terminals. If I remove the battery cables and theck them directly, the voltage correlates with the other devices.
I already tried a restart (removing and reinserting all wires), factory reset, and "toggle charger" to no avail. Any ideas?
Cheers,
Tobias
