[RE-wrenches] Outback EQ not holding voltage

[Brian Mehalic]

What’s the capacity of the battery bank? And the size of the charging sources? What’s your EQ voltage? Have you tried a lower EQ voltage setting to see if it does the same thing?

Because of this, the EQ timer does not count down properly, and so left to its own devices the system would equalize for way longer than it should, potentially forever. This will happen when doing an EQ from the solar on a bright sunny day, or the generator, or both. The customer can manually keep track of the time and manually stop the EQ after 3 hours, but that is not ideal. Has anyone dealt with this before and have any suggestions on how they fixed it?
