Just got a Bluetti Elite 200 V2 , 200 w solar panel and Charger 1,
I am just loving this setup. I do have a question , When out on a road trip with charger 1, I notice that the unit does not quit charging, until my battery gets below
12v, it looks like, which is way to low a voltage. I have tried the adaptive mode,
not any better.
Is it possible to update the firmware / software of the charger 1 so that we can set
the turn off voltage , and turn on voltage? My obd controller has this and it helps
the battery from draining
Can you tell me what the current draw is for the device with it on and no load, and current draw when the device is in sleep mode? thanks for your help,
Any update on this? I have the same set up and am experiencing the same issues. 200 Elite V2, Charger 1 and 200W solar. I saw someone using one ways on the MC4 connector to prevent this but I dont know how to apply that to the battery input so that it doesnt drain the battery after the car has stopped.
There is now an option to disable charging in the app.
The charger 1 led is still flashing so I guess it will still drain the starter battery over time, but at least it’s not drawing any charge.
A foolproof option would be to install a victron smart battery protect between the starter battery and charger 1.
The battery protect enables you to set specific voltages to disconnect the charger one.
This should not be necessary.
Ideally, the charger one will detect the spike in voltage on engine start / shutdown as it’s signal to activate / deactivate. I’m sure this could be added to the firmware.
I had similar thoughts, however, I don’t power my Charger 1 (C1) from the start battery. As I am mainly using it to charge an AC70 & Elite 100 in Silent mode, the output power is not at maximum. The auxilliary battry is a 75Ah LFP with inbuilt 20A charger, which is charged from the start battery and through a 175A can solenoid, IGN switched.
I found the sweet spot for the 20A charger is setting C1 output to 35V. This draws 19-20A from the Aux Bat for a neutral load (charge = load) and gives around 275W charge. However, parasitic load was a concern along with my need to quickly de-install C1 for use in my caravan to top up either power station from a spare 100Ah LFP. Therefore I made it plug and play, but with a Caveat. Pics below
Plug and play with Anderson totally disconnects both Chargers, C1 and a Victron 75/15 MPPT.
Both the C1 and the Victron plugged in. (Caveat at the end of the post)
When driving I don’t use solar (Solar input is solar blankets)
When stopped (camped) I want solar not C1.
Caveat - When testing outputs, I found C1’s output was only 25W regardless of voltage setting. For some reason when both the MPPT & C1 were connected, there looks like an incompatability. Easy fix as using both at the same time is not likley. As an aside, I run an Engel 40lt Combi fridge freezer from the Aux Bat, which gives me a neagative 3A load when cycling and using C1, or around 1.5Ah, which is minimal and works for me.
“Bottom line”, to remove parasitic load caused by C1 or the Victron, I pull 2 Anderson plugs. Benefit is, I also have 3 more in/outputs to the Aux Bat.
Not the answer to the original Q re App control, but my work around.
