AC500 B300K 5000W Portable Power Station
All-in-One System Portable
Modular whole-home power system. The AC500 head unit pairs with up to six B300K LFP packs (2.76 kWh each) for an 18.4 kWh total. 5000 W of pure-sine AC and 240 V split-phase capable.
Bluetti's AC500 is the most modular consumer-grade backup system in this category. The split-phase output (paired with the optional Smart Home Panel) lets it run a well pump or a 240V mini-split that most portable units can't touch. LFP chemistry, 6000-cycle warranty.

Common questions
What people ask about the AC500 B300K 5000W Portable Power Station
What's the difference between AC500 B300K 5000W Portable Power Station and a residential all-in-one inverter-battery?
Bluetti AC500 B300K 5000W Portable Power Station is a solar generator (portable power station) — designed to be picked up and moved, with built-in outlets and a solar input port. It's distinct from a residential AIO like the EcoFlow PowerOcean or Sol-Ark 12K, which is a permanent-install hybrid inverter wired into a home's main panel. Solar generators excel at backup-of-last-resort, off-grid trips, and powering specific high-priority devices. Residential AIOs are what you'd choose to back up the whole home.
What can Bluetti AC500 B300K 5000W Portable Power Station actually run, and for how long?
With 5000W continuous AC output, Bluetti AC500 B300K 5000W Portable Power Station can run anything that draws under that wattage continuously: refrigerators (~150W), LED lights, laptops, modems, CPAP machines, even small space heaters at low setting. Surge to 10000W means it can handle motor-startup spikes from compressors and small pumps. At 2.764kWh capacity, runtime depends on draw: a 60W draw runs 39 hours, a 600W draw runs 3.9 hours. (The 0.85 factor is realistic round-trip efficiency.)
How do I expand capacity?
Bluetti AC500 B300K 5000W Portable Power Station expands to 18.43kWh total via add-on battery packs from the same manufacturer. The expansion battery connects with a single high-current cable and the BMS treats the combined bank as one battery. Note that the inverter section's continuous AC output (5000W) doesn't increase with capacity — only runtime does.
Will this charge from the panels I already have?
Bluetti AC500 B300K 5000W Portable Power Station accepts 12–150V solar input up to 3000W. Most rigid 12V/24V portable panels work directly. Residential roof panels (typically 30–50V Voc) work too, but you'll need to wire panels in series to stay above the lower voltage threshold and below the upper. Confirm panel Voc + cold-temperature derating before connecting.
