Chargeverter Controlled from 6000xp

Quick question for those with a Chargeverter. If I’m using the gen output on one of my 6000xp’s to start the generator, that is using SOC from inverter to enable and disable. Do I need to set anything on the Chargeverter or just use the SOC from the inverter?

How do I tell the Chargeverter the SOC is handled by the inverter?
 
If I'm understanding your question correctly, you wish to use the inverter to start and stop the generator. If that's correct, and the chargeverter is plugged into the generator, then the generator will just start when the dry contact on the inverter switches on, and then off when the inverter sees sufficient SOC. The CV doesn't need to be connected to the inverter at all - just to the batteries, and then only through its output cables.

You probably should program the CV to stop charging at a certain battery voltage, only as a safety, in case the generator never shuts off, based on the battery voltage it sees. Voltage is a poor way to monitor a LiFePo4 battery but OK as a safety against overcharging, in this application. Otherwise, the CV will just turn on when the generator turns on, and off when the generator turns off (because it has no power). The inverter is controlling generator start/stop based on the battery SOC, and the CV is just going along for the ride.
 
I would program the chargeverter for max output (Like 57V, 100A) AND LET IT EAT. It will remember the programming, and since you have the Inverter handling start-stop, you are good to go. One thing I discovered about the CV (the new black one at least) is it has a standby draw on the AC input of 250W when it's sitting there doing nothing (aka batteries are charged/solar has it) so using it the way you are you avoid that 250w of waste while it's sitting there deciding if it needs to charge.

I limit the CVs to avoid running generator at max. My goal is to never run at more than 80% for more than a few seconds. With two chargeverters, I can get 7500-8000 watts of continuous charging from the 10K generator and it never has to run "flat out". When I had just one CV, I maxed it out and it didn't seem to care.

Again, I'm measuring 25W, so I suspect your Eyedro isn't doing a very good job of measuring low power factor loads.

I do agree with setting it to maximum and running it, then turning it off till next time. You can do this by using the Generator contacts on your inverter to either run a generator or drive a grid power relay to enable the AC input of the CVGC.
