As previously mentioned, I am upgrading my home off grid system and had to put
in flex max 100 and just wanted to report on the difference I’ve seen.
I still have the older Array up about 6300 W on trackers and the stability of
the voltage once the system is full is rock solid compared to the FM
Nick and all,
The DC Solar Classics do not have Ethernet capability or the
auxiliary relays. You can tell if it's a DC Solar Classic because
there are no speaker holes
on the front cover below the MNGP display.

Nick,
While I have no idea about those specific Classics from DC Solar, all
standard Classics have internet connectivity via either the MidNite
Solar Local Application or MyMidnite.

It’s the gfi breaker that’s tripping right?
There is another possibility. I’ve seen extremely high loads with weak
batteries cause the capacitors in the CC to dump causing the breakers to trip.
One easy fix is to install more wire between the CC and the battery or a
smaller size, within amp

Hello again Wrenches,
While the failed controller topic is fresh I want to ask opinions/advice on
arc faults. I know quite well that they can be mysterious so not sure I’ll
really get anywhere but

Here is a quick tip regarding Outback and the ghost arc fault, this can
apply to either pre-wired or wire on site Radian Power Panels, you will
need to look at the charge controller and first loosen each of the screw
down wire clamps with good light and a clear view slowly pull the wire ba
Hi Nick,
Do you have any rapid shutdown equipment on the arrays? The only charge
controller (Midnite CLassic) that we have ever had that failed with a short
on PV Input, had the Tigo Shutdown boxes on them (TS4-AF). I have always
been curious if that failure mode was due to the Tigo signal someh
What kind of fans? And are they large? On the far end of the 1300’ run?
Sounds like hat 1300’ foot run is acting like an inductive whip to the radians.
I suggest installing ferrite cores on the dc and ac conductor pairs to
attenuate transient spikes.

Jesse,
There's little advantage to 24V over 48V; as you're in the
design/bidding stage, can you use 48V instead? Then one FM60 (or
Midnite Classic) is all you need. 48V also lets you use 175A
GJ-type breakers, 2/0 cables, and 1 1/2" conduit to the battery

You can plug your module specs into this:

to see if the Midnite Classic might work for your configuration. At
lower array voltages, the Classic 150 can exceed 2500w arrays.
Depending on how critical the reliability of the system is, I often go

Hello,
I'm working on bid for a system using the FM80 controller. The specs for the
controller say the maximum STC wattage for a 24V system is 2500W. The array I
want to use has a STC wattage 2550. I called outback to ask if this was "close
enough" today and didn't get a reply (holiday weekend
