[RE-wrenches] Outback MX-60

[bob at midnitesolar.com]

Depends on the requirement for the BMS.

Usually, but not 100% always, the requirement is to get the voltage up 
to "absorb" and then stop charging.

Just set the min and max  times very low, like 1 minute and that should 
satisfy that one.

I do not remember if the MX60 had a Re-Bulk  setting but I think it did ?

The MX did not have a logic input for turning it on and off of course.  
OB had a communications
device that converted their communications protocol to Modbus or 
Ethernet I think it was which
may (or may not) be able to make it work.

Could always buy something newer and keep the MX60 as a spare.
