Xantrex SW5548 AC-IN led flashing and inverting for a short time

Thanks for the added info.
SO, it IS good that the AC1 input transfer relay appears to be working correctly (probably).
Do you know the highest battery voltage that you have seen during Bulk?
Have not downloaded the SW manual, but have the SW+ manual in the power room. Will look at that soon, as these two different inverters are quite similar.Good luck, later, Vic

Once again, you should turn off the Search Mode. Setting the Search Watts value to 0, should do this.
The Search Watts setting should be in the " Inverter Setup " menu 9 in the SW manual, here.Search mode only affects the Inverting function, but could possibly affect some of Inverting behavior that you are seeing.
Will read further in the SW manual. FWIW, Vic

Hello Vic,I will try , but I've already turn off the search mode and start the inverter manually ( ON OPTION ), still getting the same symptom.In bulk mode I dont see any change.

OK, Thanks, did not see a Search on/off, but it is a fairly fat manual, and prefer hard copy manuals, when possible.
You do need a Bulk time setting, and perhaps a Maximum Bulk/EQ time setting (perhaps).
Good luck, Vic

Set Inverter
OFF SRCH ON CHG
This is what the default screen on the inverter shows. from off you get the other three options upon turning on. From page 37 of the manual.
2.1 Kw Suntech 175 mono, Classic 200, Trace SW 4024 ( 15 years old but brand new out of sealed factory box Jan. 2015), Bogart Tri-metric, 460 Ah. 24 volt LiFePo4 battery bank. Plenty of Baja Sea of Cortez sunshine.

Hello,I have uploaded a video so you can see what happen with the unit , I've already put to 0.0 Search Watts and put to maximum BULK AND EQUALIZER settingsAs you see on the video it just stay in BULK for a couple of seconds.

johan,1. Looks like the batteries connected to the above unit DO need charging. Do you have a stand-alone charger that is suitable for your Sealed batteries?
2. Do not understand why the Inverter AC Volts is not the same as the AC2 Volts, when the AC2 LED is solid. When you say that "the output stays on", does mean that there is AC on the inverter AC output?
was the Charge LED on, or the Invert LED?Why not just stay with using AC2 for the Grid power, for now.
When the Inverter is inverting, there should be a fairly loud, BUUUUUUZZZZZZZZZZZZZzzzzzzzzzzzzzzzzz from the unit. While the Inverter is qualifying the AC2 input the AC2 LED should be flashing. When the AC2 LED stays on solid, you should hear a transfer realy clunk, do you hear this?

Gotta get back to work, VicHello Vic,- Yes I have a charger so I will charge the batteries.
- Yes when it stays on I have output voltage.
When the unit is inverting I can hear a clunk and the buzz sound when it passes from inverting to bulk and then I have ac output for a while then it goes back to flashing.

If I may humbly advise...from your initial conditions described seems you are connecting to GEN input because AC IN 1 (Utility) is somehow defective because you saw a flashing LED...which means there is no utility power sensed. This COULD be because your utility power is out of range at 129V because the setting on AC INPUTS (Menu 11) "SET INPUT UPPER LIMIT VAC" setting is below 129VAC. It defaults to 132 so this maybe be a fruitless investigation But maybe check that out. You access the SETUP menu (and thereafter Menu 11) by simultaneously pressing the RED and GREEN (ON/OFF and GEN) buttons on the 5548.
IF the AC 1 input is hosed, and you are forced to use AC 2 (GEN) then you'll need to adjust gen settings and treat the GEN as 'always on' by disabling startup times, startup loads, delays etc. Review manual page 49. I don't like giving advice on compromised systems because there are unknown conditions that could endanger you or damage your equipment. Also, be aware of derating schedule. if you are in an uncontrolled locale and it get ~^HOT^~ there, you'll need to be sure to be aware of the derating that the SSW5548 enforces.
