Lv6548's recognizing ac input but not charging

[KnowerOfLittle]

Like the title says, my split phase lv6548's recognize ac input but will not charge. I'm confident in my wiring and max charge settings but for some reason beyond me it still will not charge. Ac input is from an inverter generator and have confirmed 60hz. I've tried looking online or in the troubleshoot section of the manual but haven't come up with any solution. If anyone has some information on this issue please share.

what is your charger source priority set on ?
what is your output source priority set on ?

Unless I am mistaken you have two AIO's stacked to produce 240vAC. Does your inverter generator output 240vAC split phase? With a hot leg going to each of your AIO's?

If not in stacked mode you could use a 120vAC input on a individual AIO but once they are working together it may be why it does not charge.

Output source priority is set to utility first
Charger source priority is set to solar and utility

Your assumption is correct. I have two aio's producing 240v ac. It does put out 240v split phase.

I've tried with 120v to both aio's but will try 240v and post results.

Thank you for spending the time to help me out.

Is your input 240 split phase? Or did you simply run two branches of 120 into each inverter? If they are not 180 deg out of phase the inverters when paralleled might not recognize it as qualified input

You also need to ensure that L1 is going to L1 and not L2 insofar as your wiring goes into the inverters. I am not familiar with your inverter but it might require that you use L1 input for the inverter that is outputting L1 and L2 input for the inverter that is outputting L2. Or they both might need to be plugged into L1 on both inverters I don’t know without reading the instruction manual

Some ideas.... Just wondering, what are settings #2 (max charging current) and #11 (max utility charging current)? I have 2 LV6548s and do what you are doing occasionally. Only my generator is just an ordinary 240v... not inverter based. For me to get my inverters to charge from it, I start with #11 on a lower setting and work my way up, giving the generator time to settle in at each stage. Perhaps the inverter generator is not keeping up if you have #11 set too high and the inverter is switching . The effect is the inverter looks like it is seeing AC, but it will not charge. Another idea... depending on battery settings, maybe the inverter thinks the batteries are full? (just looking at the image you posted)
