TopologyIQ Modular Architecture — 2kWh to 109kWh
The X4400 is built on the TopologyIQ modular stacking architecture. The All-in-One configuration combines three modules: a control module (smart brain + LCD + inverter), an extra battery module (2160Wh), and a mobile chassis (1000Wh + wheeled base). Every module uses a patented quick-disassembly design — split into individual modules in seconds to carry up stairs or load into a car trunk. Stack more modules to expand from 4.2kWh to 109kWh on demand.
4400W Pure Sine Wave — 18 Devices at Once
8 AC outlets (220–240V, 10A max each), 4× USB-C PD 100W, 2× USB-A 18W, 2× DC5521 36W, 1× XT60 360W, 1× car socket 120W. Total 5116W AC+DC combined output. From a fridge and a TV to a drone and a laptop — everything plugs in at once.
Real-World Runtime
- Rice cooker (330W) — ~10.4 hours
- Portable AC (420W) — ~8 hours

UPS PRO 0ms — Zero-Gap Dual-Inverter Backup
Two inverters work in tandem in the All-in-One configuration: one charges the battery internally while the other feeds your devices externally. When the grid drops, power switches in zero milliseconds — your equipment never blinks, never restarts, never loses data. UPS LITE (<20ms) available in Standard/Outdoor single-inverter setups.
PowerRaise Fast Charging — Full in 1.5 Hours
4400W dual-port AC charging (2200W + 2200W): 80% in 1 hour, full in ~1.5 hours. 1000W solar (XT60, 11–60V): ~5 hours. Hybrid AC+solar at 3200W: ~2 hours. 700W quiet charging mode for overnight silent top-up.
17-Algorithm BMS + Tesla-Grade Aluminum Frame + 5VA Fireproof Casing
17 protection algorithms covering over-discharge, overcharge, cell balancing, temperature, voltage, overcurrent, short-circuit, and more. One-piece die-cast aluminum alloy frame (same process heritage as Tesla vehicle bodies) withstands violent impacts with 200kg load capacity. 5VA fireproof shell heat-resistant after 16 hours of direct sun. 9 finned heat sinks + 8 adaptive-speed DC brushless fans.
Four Silent Wheels + Telescoping Handle
Luggage-style telescoping pull handle. Four silent rubber wheels. Quick-release modular structure for carrying up stairs or loading into vehicles. All-terrain Off-Road configuration available with larger rugged wheels and front swivel casters.
