It is also a practical choice for users looking for a compact hybrid all in one energy storage systemy that combines power conversion, storage, and intelligent control in one unit.

Product Features & Advantages

All-in-One Integrated Architecture

The PS8 combines the inverter, battery, MPPT controller, and energy management system in a single enclosure. This highly integrated design reduces external wiring, shortens installation time, and minimizes component compatibility issues. For installers, distributors, and homeowners, it offers a more efficient and dependable deployment experience than traditional separate-system setups.

Stable 4kW Hybrid Inverter Output

The system delivers 4kW single-phase AC output at 220 / 230 / 240Vac with total harmonic distortion below 3%, providing stable pure sine wave power for common household appliances. With a transfer time of less than 10ms between utility and inverter mode, the PS8 helps keep essential loads running smoothly during grid interruptions.

Advanced MPPT Solar Input

Supporting up to 6,200W PV input power and a wide MPPT voltage range of 60–450Vdc, the PS8 enables efficient solar energy harvesting under different installation conditions. With a maximum PV input voltage of 500Vdc, the system allows flexible solar array design and improves overall energy utilization.

Long-Life LiFePO4 Battery Technology

The integrated Lithium Phosphate Battery offers excellent thermal stability, safety, and long service life compared with traditional battery chemistries. With up to 8,000 cycles at 80% depth of discharge, the PS8 is well suited for daily residential cycling applications. Its intelligent BMS continuously monitors voltage, current, and temperature to ensure safe and stable operation.

Smart Energy Management

The system supports multiple operating modes, including self-consumption, backup priority, and time-of-use management. Users can adjust operating parameters based on household load profiles and solar generation patterns, improving energy efficiency while reducing electricity bills.

Compact and Installer-Friendly Design

With compact dimensions of 550 × 180 × 800 mm and a total weight of approximately 82 kg, the PS8 is designed for convenient indoor installation. Forced air cooling supports stable operation, while RS-485 communication and an optional Wi-Fi module enable monitoring, data access, and remote diagnostics.

Application Scenarios

Residential Solar Self-Consumption

The PS8 stores excess solar energy generated during the day and discharges it when household demand rises in the evening, helping increase solar utilization and reduce dependence on the grid. It is an ideal choice for homeowners building an efficient all in one home energy storage system.

Home Backup Power

During a power outage, the system can provide seamless backup for critical household loads such as lighting, refrigerators, communication devices, routers, and home office equipment. This makes it a dependable energy solution for everyday residential resilience.

Time-of-Use Optimization

In regions with variable electricity tariffs, the PS8 can charge during off-peak hours and discharge during peak-rate periods, helping users lower electricity costs and improve energy economics.

Hybrid PV and Grid Power Systems

The built-in hybrid architecture enables coordinated operation between solar panels, battery storage, and utility power, creating a stable and efficient household energy solution. For users comparing residential systems with products such as a Portable Solar Power Station or a Solar Camping Generator, the PS8 provides a more robust fixed-installation option for long-term home energy independence.
