Back to the original question. 1. FXR/A has generator support, turn it on if its not on. And the FXR/A has a generator setting for AC input that and I don’t really understand how smooths out this issue, but it can. I had a issue somewhat like this, 8Kw radian and 12kw genset. Radian or generator worked the stove ( gas stove, just the electronic controls and some LED lights). But when the inverter was charging, the stove wouldn’t work. Setting it to GENERATOR for ACINPUT solved the issue. Further programming would be to check that the low AC volts isn’t too low. I set it around 108 as the low usually, and that might be too low for this unit, so try setting that up higher.
2. possible programing issues might be solved or at least tested by turning down the AC generator input, or charger amps. Its my first test to confirm if the generator is being overloaded. Also try with reduced loads. 3. has the generate been serviced lately? oil change, air filter, etc. Often the reason for things not working well. 4. installing capacitors would be my last option. As someone who’s run a full sized house for 14 years with a FX 3524, and a honda EU2000 as my only generator, I can say categorically that it works just fine. Washer, refrigerator, freezer, all the standard appliances. Would a larger generator speed up the charging, yes, does this work yes. Would a larger inverter help, for me only with battery charging, not with loads, I’ve got no issues with running my house. I don’t know why this person has a 2812. I know of lots of people who have an existing system that works well for them, and really only upgrade to pure sine because of the new appliances. And with more high efficiency appliances: battery powered vacuum cleaners and tools: front load soft start washers, water pumps, variable compressor refrigerators, etc more and more can be done with less and less inverter power. Yea sure, if you want more power, then totally agree with going 24/48v is the way to go. Let us know what the fix turns out to be.
