You could swap it out with a FM-80 and do 4 strings of two modules in series.

Hi Jason, I have the same set up. These are the array and cc
breakers. Although we are having a power outage right now, the DC
shunt is doing its usual crazy reading from time to time. Chris

Hi all,
I have a client that wants to replace a PV array
that is aging and hurricane damaged. It's a rather old array
of unknown rating connected to a MX60 via a Flexware 500 DC
enclosure (48V).
I'm planning to install eight REC 450 Alpha Pure
RX in series. I'm going to need a 600 volt charge controller.
I'm considering a Midnite Hawk's Bay unless someone has a
better idea.
The customer sent me this crude image. I can see
the two inverter breakers on the right. I am wondering what
the two breakers on the left are. I'm thinking one of these is
an 80 amp breaker for the output of the MX60. The other one is
probably a PV input breaker of unknown rating. I would need to
change these to accommodate the new charge controller. The
Midnite Hawk's Bay 90 requires a 125A output breaker. Does
anyone know if there is an Outback breaker of this physical
size and 125A rating to plug into this DC FlexWare enclosure?
For the PV input, I should be able to get whatever breaker is
required for this single string of PV.
I'm all ears if there is an easier way to go
about this with approximately 3,600W of new PV.
Thanks in advance!
