I have had an issue with the SOC algorithm and voltage readings. After research on this forum I determined that it was a problem with the voltage measurement difference between the smart solar and multi. I got my SOC back up to 100% by increasing the absorption voltage to 59v from 57.6v. I didn't want to leave it this high so set about reducing the absorption voltage in the multi remotely (I do not have computer access where my solar is). So far, I have reduced the voltage down to 54v and the multi is still not recognising when the smart solar switches from bulk to absorption. I reduced the voltage again and now the multi will not start up, flashing low battery and then overload in quick succession and then switching off. Nothing else has changed in the set up which was working well for a month, SOC aside. I am assuming I have lowered the absorption and float charge voltage too low and it has interfered with another setting. Can I access the multi remotely with veconfigure even when it is off or do I need to buy a Mk3 to configure it directly? I'd prefer to avoid the $100 cost if possible...
