Ray,
The only fault warning we got was the batteries (a 48v, 1,000 amp hr
HuP) were boiling and using a lot of water, and expected power
production was down. OutBack said this problem was corrected with
new software. The system was installed in 11/2005 and the inverters
replaced in spring 2006. If your inverters are newer, it should not
be a problem, but it might be worth discussing with OutBack.
Good luck,

Ventilated, but small enclosure. Definitely a possibility to
consider. What fault warnings were you getting?
Thanks,

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
