Hi John,
What is the error code on the Mate when you show up, or is there
none? As far as turning on the inverter remotely, I think you would
need internet on site from a DC source to let any data monitoring
software remotely control when the inverter is off. Is there a back
up generator? What does the data monitoring show for battery Voltage
around that time period?
Best,

Wrenches,
I have a mountaintop transmitter site with an FX3524, Flex Max
60, some PV and 12 L16 Bateries. They are set up in a small
building used for the ski patrol at a ski area. There is a 25'
freestanding lattice tower on the roof with high speed wireless
internet transmitter and receiver antennas. It is a relay site and
direct signals to customers. We have a problem with the inverter
shutting off ("off" indicating on the mate ) somewhat randomly as
far as # of days apart but strangely all the shutoffs have happened
between 10:08 PM and 10:30 PM. We thought it might be an inverter
or mate problem so we replaced both with new units. The problem
continued with the new equipment. We then suspected the data
logging connection may be sending a stray signal so we removed the
data connection from the FX (removed the connection from the mate).
I then also removed the connection from the FM 60 to the HUB,
connected another MATE directly to the FM 60 and connected this new
mate to our data aquisition so that we could still monitor battery
voltage. The only common connection now is the batteries and also
our data system is being powered from the AC out on the inverter.
Now. after almost 3 days of operation, the inverter has shut off
again at 10:15 PM yesterday. We know this as the data stopped
coming in due to the loss of AC power at the site. My take is that
the data monitoring equipment has nothing to do with the problem...
also reinforced from several similar setups working flawlessly. The
only thought I have is that the nearby cell tower is sending out
some interference. Does anyone have a clue as to what this problem
could be. My customer is really MAD. All their brand new high
speed internet customers are having regular long outages. We have
to trailer a snowmobile to the mountain almost an hour away and go
to the top to push the ON button. Also, any comments on other data
systems which could turn the inverter on remotely.
