Ray,
Is the inverter in a ventilated space? We had a similar problem with
older OutBacks in an unventilated shed. OutBack sent us upgraded
inverters and we vented the shed and have had no problems since.
Good luck,

I considered that there could be something happening due to the
grid, as this guy is way out on the end of the line going into his
own utility transformer.
But then the inverter should show a fault light, and it should try
back again, once the grid voltage drops.
Instead it initiates a full charge cycle and will not connect till
the next day.

HI Ray,
Have you checked the grid voltage to see if there is variation
during the day which would be enough to kick the inverters out of
connection?

Subject: [RE-wrenches] Outback Grid Problems
We currently have a Grid Tie system with a pair of Outback
inverters that are regularly dropping out of sell mode, and
letting the arrays spend all day charging the battery bank.
It seems to do this several times a week, and the customer is
losing substantial production, and gassing the batteries too much.
It will reset itself the next day, or the customer resets it by
turning off the inverters manually.
The system is 24 v, with an old array of 1800 watts running
through 2 FM60s, and a new array of 2800 watts running through
another pair of FM60s.
The battery bank is HUP about 4100 Ah @ 24 v (3 strings of 1375 Ah
each) Big battery, I know, but the customer is an electrical
engineer, who wanted maximum storage capacity.
Outback tech support has not resolved the issue, and this has
turned into several service calls, and customer frustration.
We've tried running the controllers through the HUB, and also
independently, and that doesn't make a difference.
I have numerous Outback GT installs dating back to 2003, and have
never had a problem like this.
Any help or advice would as always be greatly appreciated.
Thank you in advance fellow Wrenches,
R. Walters
