[RE-wrenches] FX2000 / Trojan battery question

[The Office of Tom Duffy]

Bob

On the other note: Were the L-16s in series or series/parallel? Also were
the voltage readings and Hydrometer readings done on an active bank or "at
rest" and what were the readings?

Subject: [RE-wrenches] FX2000 / Trojan battery question

 

Just visited a site with a 04 version FX2024 The inverter is shutting down
and showing "low AC output voltage" 

It is hooked to 4 Trojan L-16 G batteries. When i arrived the voltage was
23.8, the other day when i arrived it was 25.5 volts and shut down both
times with the same error showing. There are 1050 watts of panels and an MX
60 on the battery bank also. In the past when the batteries went low it
would show a low battery error, so i don't expect that is the problem. Loads
are minimal

Disconnecting the battery or starting the generator clears the error.

 

When i called Outback i was told there was a $250.00 "out of warranty
charge" as well as a retail of $1400 for the boards. She also insists it was
probably a bad battery bank, or at least needing an eq charge. It just had
one 9 days ago. The hydrometer readings are all close and the voltages
similar.

 

Anyone run into this before and have any knowledge on this error? 

 

On another note, has anyone had any Trojan L-16 G batteries with cell
failures? The date code is J8 

I have had 2 in the last year, one was under warranty and the last one out
of warranty.

Anyone else had this problem or am i just unlucky?

 

Thanks,

Bob
