AC 200max with B300. Trying to run Velit 12v air conditioner. its a new build so this is the first thing I’m testing before moving on.
Velit powers up and after 30 seconds or so i get error code E4 on the Velit (error = drop in voltage below 10.5v). Fan still runs but it isnt cold air pushing through.
AC200max read dc output of 13.5V. my output power hovers around 10w and then spikes to 400, which is when the error code occurs, then it goes back to zero and it recycles and does the same thing.
i have the aviator plug ran to a master on/off then to a fuse block. Velit is the only thing plugged into it.
this is my first build and first time using a bluetti or wiring this set up.
From what you have described I would say that the actual wattage exceeds the maximum for the AC200Max.
The RV (Aviation Plug) port has an overload wattage of 400W.
Refer to specification page in manual under DC OUPUT RV*1
Probably not what you wanted to read, sorry!
Hi @ryan1234, The rated voltage and current for the RV port on the AC200MAX is 12A/30V. We believe the issue might be caused by the air conditioner’s startup current being too high, which lowers the output voltage from the AC200MAX, making it unable to properly power the air conditioner.
Please check if the air conditioner has an AC connector. If it does, try using the AC load. Alternatively, we recommend purchasing an AC-to-DC conversion cable, which would allow you to use the AC200MAX’s AC output to power the air conditioner.
