4000w Home Powerstation Lifepo4 Battery Charge 5000w Portable Solar Generator 5040Wh

The SOUOP S5 4000W Portable Power Station is a heavy-duty 5040Wh (48V, 105Ah / 1,575,000mAh) home energy system built for whole-home backup and off-grid living. Powered by the latest 4000W pure sine wave inverter (5000W rated, 7000W peak), it drives almost any appliance — from microwaves and refrigerators to professional power tools and high-output lights — through five AC sockets (110V / 220-240V). Capacity can be expanded to 10.08kWh with an add-on expansion battery for extended blackouts. EV-grade LiFePO4 cells deliver 3500+ cycles at 80% depth of discharge, while multi-channel charging reaches a record-breaking 4250W to fully recharge in just 1.5 hours. With up to 16 output ports (including dual USB-C, four USB-A, 12V DC and Anderson), WiFi / Bluetooth APP control and a colour LCD display, the Mega 5 is a complete plug-and-play home backup power system.

Engineered for serious power needs: whole-home backup during blackouts that last for days, off-grid cabins, RV and tailgating, job sites and outdoor events. The 4000W output and expandable 10.08kWh capacity keep refrigerators, freezers, microwaves and power tools running, while the 1.5-hour fast charge and AC / PV / EV inputs mean the S5 is always ready. Quiet, emission-free and app-controlled, it delivers dependable power whenever and wherever you need it.
