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. ..................................................................................................

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.

So, they all had to be in series to operate at 24v (FX2024 is a 24v inverter).

Also were the voltage readings and Hydrometer readings done on an active bank or "at rest" and what were the readings? Tom Duffy Systems Design Engineer [email protected] 575-539-2111 X 301 ---------------------------------------------------------------------------- From: [email protected] [mailto:[email protected]] On Behalf Of robert ellison Sent: Thursday, October 01, 2009 5:40 PM To: RE-wrenches 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?
