I am going to chase this down. Only certain types of products have the issue it seems. I am going to try to add solid state to the gas tubes using a different design that eliminates the steering diodes. Seems like the steering diodes are causing the problem in some situations. From: George

No diodes, just gas-tube for large surge event suppression. Obviously not as much protection though. I'm seeing more CRC errors than I'm comfortable with on the cards with diodes. Rev G is definitely better though. I've broken the shield at various sites while testing to rule out any potential

I would recommend them. https://www.exeltech.com/products/inverters/inverters-above-2k-watt-mx/ Never had a problem with them. You need either a control card or a master inverter in each rack. I prefer the control card so all the inverter modules are the same. I also like the transfer

Funny, the product is so simple. Jacks. Tubes. Electrodes with gas between them from the Ethernet lines to ground. The only way the tubes can affect the circuit is if they are ionized, which means a high voltage coming from somewhere. could be coming from a ground loop or ??? Or a tube

You could also look into individual 1500W meanwell true sine wave inverters, running in parallel off your 48vdc battery bus. You can parallel as many as you need. Don't load any individual one with more than 1300W constant. Wire up the output from each meanwell to 120vac PDUs with amperage meter
