That was an issue back in the 90s with the original Trace SW 4024
inverters as well. The solution was just to temporarily set the normal
bulk setting to the required EQ voltage. Never did figure that one out,
but they were otherwise great inverters that are still in service today.

I recently discovered a critical problem with a client's SW inverter
and I want to know if others have encountered this.
It's an SW4024 with Flooded Lead Acid batteries. The system is
configured using the Custom Battery setting: Bulk and Absorption are
set to 29.2 V. Equalize is set to 32 V.
The problem is when Equalize is enabled, the system goes through Bulk
and Absorption just fine. However, when it switches to Equalize it
doesn't actually equalize. What I observed was the voltage actually
decreased to 0.5 V below the Absorption Voltage setting.
