Postby lgott6 on Sun Aug 22, 2010 9:40 am

Hello, I would like to know the Proper protocall to disconnect (8)24v 2 string application. Replacing with new. I am a new user to Outback. We are off grid. We have the MX60 PV MPPT with 2 inverters. Sequence to throwing breakers and any protocall for mate controller? Thank you Leah

Start generator. AC bypass breakers to "Bypass".

With the Mate, send the inverters an "Off" command.

Turn off the PV array breakers first, then charge controller input, then charge controller output breakers. If you have fuses in the combiner box, ignore the PV array fuses -- the goal is to reduce the amount of current before operating any circuit breaker since disconnecting under high current can shorten the life of a circuit breaker.

Turn off DC breakers to inverters.

Disconnect the negative battery cable, then the positive battery cable.

Assembly is in the opposite order of disassembly.
