Bought 2 x Bluetti AC300 with 8 of the B300 batteries, need help choosing panels please!

Hi, I'm pretty new to solar but somewhat knowledgeable (about the basics). I bought two Bluetti AC300's with 8 of the B300 batteries for the full expanded set (link below for specs, plus an additional 4 B300 batteries).

https://www.bluettipower.com/products/2-ac300-4-b300-p030a?


I can't figure out what size/configuration panels to get without going over the amps or volts. And to get the full 2400watts of input. Or would that be 4800watts of input since I bought two Bluetti 300's? (2400watts per Bluetti?)

I don't care what size panels, 100 watt, 200 watt, 330 watt.... Whatever works.

Thanks! Any help or input much appreciated ?

If you go with STC conditions, the Solarever 440w panels will get you 1,320 watts per string of 3. The Q Cells 405w bifacial will also give out 1,215.

If you have colder weather, then things get a bit harder to figure out.

One thing I was thinking about doing is getting a D300S for each AC300 that would allow up to 500v in and it would adjust voltage and amps to the AC300. It is an extra $600 each, but makes it much more flexible.

That is awesome. Thanks so much for your reply! I'll look in to everything you said. Did you purchase an AC300 too?

No, I decided to roll my own as the prices were close enough that I could make a solar trailer with more capabilities in it than the AC300.
