[RE-wrenches] Outback EQ not holding voltage

[Dave Tedeyan]

Hi All,

I've got an outback system (Radian 8048A, 2 FM80, 16 Trojan L16RE-B) where
when the customer equalizes, the batteries hover right around the EQ
voltage, but will often dip to 0.1v less. 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?

This system is 3-4 years old, and the issue only started in the past year
or so.

Cheers,
Dave
