The P5000M-3500 is a complete, premium-grade off-grid power package designed for high-demand applications, backup power, and sustainable energy independence. Delivering up to 5kW of continuous AC power and storing 5,120Wh of energy in a durable LiFePO₄ battery, this system is paired with a 3.5kW high-efficiency solar array for fast, renewable charging.

Unlike conventional off-grid setups, the P5000M-3500 is fully pre-wired and integrated into a single portable solar generator unit. All core components — including the battery, inverter, dual MPPT solar charge controller, AC/DC distribution, safety switches, connectors, monitoring display, and output sockets — are already built-in. This means that installation is as simple as connecting the solar panels via their MC4 connectors, with no other wiring or configuration required. Within minutes of delivery, you can have a fully operational off-grid power system without specialist tools or complex electrical work.

Whether you’re powering an off-grid home, supporting a construction site, or safeguarding against power outages, this system offers reliable, rugged, and ready-to-deploy energy anywhere.

Includes:

  • 5000W 5120Wh Portable Solar Generator (P5000M)
  • 8 × Sharp NU-JC430B Full Black Monocrystalline Solar Panels (SRP-430B)
  • 2 × 10m 6mm² Single-Core Extension Cables with MC4 connectors (10M60)

 

Core Components

At the heart of the system is the P5000M Portable Solar Generator, equipped with a 5,120Wh LiFePO₄ battery rated for over 6,000 cycles at 80% depth of discharge. It delivers up to 5kW of AC output through four 2,000 W sockets, with an additional 5kW EPS port for powering a single high-demand appliance. Charging options are flexible — choose from a 2kW slow AC charge via a standard mains socket, a 5kW fast AC charge via a dedicated wired outlet (professional installation required), or solar charging up to 7kW using dual MPPT inputs (500V / 14A each).

All power management is built in — no separate inverter, charge controller, or wiring panels are needed. Users can monitor and control the system through a bright LCD display or the Power Zero App via Wi-Fi or Bluetooth. With an IP65-rated dust- and water-resistant casing, heavy-duty cooling, and integrated wheels, the P5000M combines durability with portability, making it ideal for both stationary and mobile use.

The system also includes eight Sharp NU-JC430B Full Black Monocrystalline Solar Panels. Each 430W panel features advanced TOPCon cell technology for excellent performance in high temperatures, low light, and shaded conditions. Their IP68-rated construction is resistant to PID, salt mist, ammonia, snow, dust, and sand, ensuring dependable operation even in the harshest environments. Pre-fitted MC4 connectors make linking them to the generator quick and secure, with no special tools required. Backed by up to 25 years product warranty (EU) and 30 years performance warranty, these panels are built for decades of service.
