Using Bluetti 200w solar panel to charge rv AGM battery

My son purchased Bluetti’s AC180 and the 200w solar panel. He wants to use it to charge the 180 and also the rv Agm battery. What do we need to do to charge rv Agm battery?

You can do this in the following ways:
Solar panels charge the AC180 and the AC180’s cigarette lighter charges the RV battery.
Or you can purchase our upcoming D40 accessory, where the solar panel can be fed directly into the D40 to charge the battery. (But the D40 may take at least two weeks to be released)

This is excellent news @BLUETTI but do you plan to support third-party 48V systems, to interface with Pylontech batteries for instance?

Kinda would be also interesting if and when it comes to EU countrys

When I see products like D40, D300s and co, it reminds happy childhood memories of my dad bringing back home some glorious Radio Shack and Tandy gadgets back in the late 80s :slight_smile:

Thanks for the feedback. Excited to get my hands on the D40 - need two of them. Great concept.

Sorry, after checking with the techs, the D40 does not support 3rd party 48V systems. However, 12V/24V batteries can be connected in the middle of the D40.

D40 plan will be launched in the United States as early as December, and it may not be available for sale in Europe until next year. :worried:

If you want to go simple buy a battery charger and connect it to the AC outlet of the AC180. Just like you would charging a battery from home. If the RV has a built in battery charger, connecting the RV power cord to the AC180 would work even easier. The cost of this approach is you lose wattage efficiency converting the AC to DC if the efficiency is no big deal, that is what I would do. The more complicated approach is using a charge controller connected to your solar panel and connect the controller to the battery. The AC 180 would have to be connected directly to the solar panel and not using the charge controller.

Can the D40 convert the 48v/8amp port on the new AC200L to a 12volt/30amp output to power dc appliances in van conversions with a fuse block like the AC200MAX was capable?

Hi @Splummer480
The D40 cannot be connected directly to the fuse box, its output has to be connected to the battery.

Thanks for the response, I understand. My question is does the D40 convert the 48v/8amp port from the ac200l battery to 12v/30amp output to run multiple 12v appliances…water pumps, led lights and a fridge? Thanks in advance.

Sorry, D40 does not support the conversion you mentioned.
