I know enough to not be too dangerous
Hello, I have an EG4 6000 XP (Soon to be 2), I have a hodge-podge of 200AH lithium batteries attached to it, so I have to run in lead-acid mode.
Which is fine, I have a shunt and all the batteries are Bluetooth. The issue I'm having is, on most days, it runs the batteries completely flat (BMS Cut-off) and I really don't want to do that. The web console states I can set the batteries to a higher cut-off voltage (pictured, I tried 46V but I'd like to be at true 20% which should be 51.2V), yet when I attempt to do so, it shows an error (Operation failed, error code: 3). I'm hoping an EG4 rep sees my post as I consider this a significant firmware bug.
Now, the manual states the highest you can set cut-off to (in LA mode) is 42V. That's just WAY too low for LifePo4. But because I have "Generic" batteries with no comms, I'm forced to use LA mode.
The only solution I can think of is buying a battery that will integrate properly, But that solution sucks for me financially.
Am I wrong here, or do we need the firmware tweaked to allow a much higher cut-off Voltage in Lead acid mode? (Like the web interface states)
Someone have another solution?
