AC200L + Charger 2 + DC Hub (for Charger 2) + Reverse charging disabling itself

Product Discussion Accessories

Hi,

I just installed and set up the Charger 2 + DC Hub on my camper van.

The Charger 2 is connected to the van’s battery, my PV (4x Ecoflow 100w in series), DC Hub, and my AC200L

After setting everything up, everything looks good. I can see all the components in the app, all devices can see each other. Great!

I also have a D40 DC-DC charger that I was hoping to replace with the DC Hub (30A max vs 50A max and a single cable to the AC200L for all the DC stuff.

Then I decided to test the reverse charging. I enable trickle charging, and the DC Hub turns off. Ok, not ideal, but it’s not the end of the world. The problem is that once the van battery was topped of, the reverse charging didn’t just stop, it switched to disabled. I switched the ignition to accessor, turned on a few things to discharge the van battery below 12.6V (that’s what the app says that will trigger the trickle charging), and nothing. Even though the battery was well below 12.6V, the Reverse Charging stayed off.

I tried this multiple times, turn RC on, top up the battery, RC switches itself to disabled, discharge the van battery below 12.6V, nothing. It never switched back to reverse charging.

On top of that, the DC Hub never turned the output back on, even though I had the “System Switch Recovery” option enabled in both, the Charger 2 and the DC Hub.

The DC Hub being turned off when reverse charging is enabled, is annoying, but I can keep the D40 for critical stuff (i.e., router, fridge, etc.), But having to manually turn it on every time is a major pain.

And the reverse charging disabling itself, especially when I wanted it to trickle charge the battery when I’m not using the van, that kind of defeats the whole point of having that feature. Imaging having to remember each day to re-enable to prevent the van battery getting discharged.

Anyone else having any of these issues?

There are so many undocumented nuances for the DC hub. This was the first place I saw that reverse charging disables the DC Hub, and it does not even show in the app as an option or that it exists still. So I can’t use the anderson connector and reverse charge the car. It’s also not very well documented that the PV port connected to the portable power station cannot power the DC hub and requires a full time P090A port expansion battery to reverse charge.

I am seeing an error with my B230 as the parking battery.
Error code: G053 it can reverse charge okay and things look normal but it keeps showing me this random error code. @BLUETTI what does error# G053 “Pack Output Undervoltage” specifically mean?

Hello,

Thank you for your message regarding the G053 error, which indicates output under-voltage related to the battery pack.

  1. Please confirm that the battery pack is charged and that the connection is secure.
  2. If you need to output through the pack, please ensure that the battery pack is powered on before turning on the charging switch for Charger 2 (C2).
  3. If you encountered this error after turning off the charging switch for Charger 2 and then unplugging the battery pack, please check whether the ARM is version 09 or an earlier version. If it is, an upgrade to the ARM is required (waiting for release from development).
  4. Additionally, if you were charging the battery pack and then unplugged the cable, this would trigger the error. Please confirm if this action was taken, as it would be considered a normal alert.

If you have any further questions or issues, please let us know!
