Hello all.
Our MultiPlus 12/3000/120-50 has been acting strangely, lately. On several occasions, when we have connected shore power and used a Touch 50 display and Cerbo to switch the MultiPlus from Inverter Only to Charger Only, the MultiPlus has changed to Charger Only for a split second and then jumped to On. After it jumps to On, we switch it back to Charger Only and it stays there. Other than this new, intermittent problem, the whole system seems to be fine.
Are there any clues as to what might be going on with our MultiPlus? It’s product ID is 2600, with Firmware version 481. Yes, I know, this is not the latest firmware, but updating a MultiPlus is not easy. We don’t have a laptop. We have iPhone and iPad only.
Thank you.
