Anyone else having an issue with the Charger 2 shutting itself off after a period of time? I’ve installed two of these units in separate Transit vans, and they both appear to be having the same issue. For reference, I have two 100W solar panels wired in parallel into the PV input, and I’m connecting the alternator charging positive to the Transit’s CCP2 and the negative to a negative post in the driver seat base.
After a given period of time where the Charger 2 isn’t receiving any power input from solar or alternator charging, the unit will shut itself down (The green power light turns off). After this, when starting the vehicle or when the sun comes out to power the solar, neither of these power inputs wake the charger 2 to send the power through to my AC200L. The unit will also not be able to be found by the Bluetti app in this state, so I have no way to simply restart it. The only way to turn the unit back on I’ve found is to physically unplug the ALT negative cable, and also both positive and negative PV cables, then re-plug them. This fully restarts the charger 2 and makes it think it’s just been installed for the first time.
I’ve tried adding a D+ signal cable wired to the van ignition on, which doesn’t seem to change anything. I’ve also made sure to update all of the firmware IoT and system updates that were available for the Charger 2, but the issue persists. Hoping this is just some glitch that is going to be ironed out in a firmware update soon, but I’ve only seen one video online of someone else having this problem:
