Bluetti EP6K EnergyPro 6K Smart Home Backup+ AT1 Parallel Connection Kit
The BLUETTI EnergyPro 6K is a whole-home LFP battery + inverter that AC-couples to existing rooftop PV and parallels via the AT1 smart distribution panel. Each EP6K provides 5.76 kW backup output and 7.68 kWh usable storage (NEMA 4X/IP65, passive cooling); with the AT1 Parallel Kit you can stack up to five units for ~28.8 kW/38.4 kWh.
Key Benefits
Parallel Power & Capacity: AT1 Parallel Connection enables multi-unit EP6K stacks—scale from one unit to as many as five for larger homes.
Drop-in for Existing PV: AC-coupled design works with common rooftop inverters to create an outage-proof microgrid.
All-in-One Backup Hub: AT1 panel manages grid, generator, EV/vehicle power, PV microinverters, and smart loads with NEMA 3R construction.
High Efficiency, Quiet: 98.4% max / 97.5% CEC, passive cooling ≤31 dB.
Special Technology
AT1 Smart Distribution: Revenue-grade metering & multi-port switching (grid/backup/ESS/generator/solar/smart load) with Wi-Fi/Ethernet/4G/RS485 for control & monitoring.
EV Integration: When paired with AT1, system roadmap includes bidirectional EV energy features for extended outages.
Warranty
EP6K & AT1: 10-Year Manufacturer Warranty.
Best Uses
Whole-Home Backup & TOU Shifting: Critical loads today; expand to multi-unit stack as needs grow.
PV Retrofits: Keep your existing inverter—EP6K AC-couples for seamless backup.
