[RE-wrenches] Outback MX60 Replacement

[Tyrone Houck]

I don't have another recommendation for a 600v charge controller but I can
tell you Midnite does make a standard, single space panelmount 125a
breaker. Also keep in mind the PV input breaker would have to be 600v
rated, also readily available from Midnite..
