hi all
the battery voltage is to low. even 25.5 is low if it is charging at all. The battery size might be to small, but it depends upon the load, (both AH and Amps) , check gravity of all cells, and check voltage of all batteries. It sounds like a battery management problem.. Get either a carbon pile tester or a Mho's meter and test in either 6 volt or 12 volt configuration. The problem is, you would like to know how the batteries performed before they were cycled.
I am going to a site on mon or tue that has a 2 yr old battery set 24 volt, L16s I will send some numbers then. unless someone else sends data first.

In other words, check your battery voltage under an actual load, one that will be higher amps than any charging sources - such as the panels - coming in.
As William noted, that is a pretty small battery bank for that size inverter and I would suspect they have been hyper-cycled.

Friends:
A "Low AC Volts" error is very typical for a cave in battery voltage under load. I've reported in this forum before the propensity of Outback inverters to misreport error conditions.
4 L-16s is a very small battery bank. I would not be at all surprised if this was indeed a battery or related wiring problem.

Tom,
The L-16’s are 6v. So, they all had to be in series to operate at 24v (FX2024 is a 24v inverter).

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?

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
