Compared to all-in-one units, the modular design significantly shrinks the overall size and weight without losing flexibility. AC500 is 100% modular and can accept up to 6×B300S (3,072Wh each) expansion battery packs, adding up to an overall capacity of 18,432Wh – Power your whole family’s basic needs for DAYS either in daily use or power outages!

Besides B300S, AC500 is compatible with up to 4*B300 battery packs (3,072Wh each). More surprisingly, you can connect both models simultaneously to customize the capacity according to your particular needs.

For those who purchased AC300+B300 combo while looking for higher AC output, they can just buy AC500 alone to work with B300, then get a 5,000W pure sine wave inverter.

* 3,000W AC output for AC500+1*B300, and 5,000W for AC500+2*B300 or more.

Being the first solar generator with 5,000W continuous output power, AC500 allows you to run multiple electronics simultaneously and even effortlessly run heavy-duty appliances, including air conditioners, heaters, ovens, cutting machines, etc.

The “Split Phase Bonding Function” lets you combine two AC500 units (with at least 2*B300S or B300) for a massive 10KW output power if integrated into your home grid.

AC500 is equipped with 16 outputs for almost 99% of devices. Now, you can get rid of the messy adapters. In addition to L14-30 and TT-30, the 50A NEMA 14-50R, with 5000W power,  is specially designed for campers, DIYers, RV travelers, etc.

Waiting for recharging is never a pleasure. With the wall outlet and solar panels plugged in, the AC500 system supports up to 8,000W* impressive input rate. Get the system recharged before you pack up for the camping, and your power will be ready when you are.
*The 8,000W input rate requires at least 2*B300S packs.

Charge in Any Way You Like
​No matter where you are, you can charge your AC500 system at any time.

 For those who intend to have a more off-the-grid lifestyle or take a longer trip into the wild, BLUETTI AC500 can handle solar arrays of any size up to 3,000W. With such a large capacity, it usually takes a long time to recharge. However, thanks to the max 3,000W solar input, you can fully charge it in about 1.5hrs.
*When the output power of the rooftop solar panel is between 3,000W~5,000W, a BLUETTI D300S is required (sold separately).
