SHENZHEN, China – March 2021 – Lingtech, a global provider of clean energy solutions, today officially unveiled its innovative 103kWh/50kW Hybrid Battery Energy Storage System (Hybrid BESS). The system’s standout feature is its direct PV input capability with 4 built-in MPPT (Maximum Power Point Tracking) controllers – eliminating the need for external solar inverters and enabling the system to function as a standalone microgrid core. This design makes it an ideal solution for power-unstable regions and remote off-grid areas.
Conventional storage systems typically require external PV inverters to achieve solar-storage integration. Lingtech’s 103kWh/50kW Hybrid BESS changes the game by integrating MPPT controllers directly into the system, featuring 4 independent MPPT input channels that can simultaneously connect multiple PV arrays with different orientations or specifications – maximizing the generation efficiency of every solar panel. The system itself serves as a complete microgrid control center, independently handling generation dispatch, storage management, and load power supply – all in one compact unit.
The built-in 4-channel MPPT controllers track the maximum power point of each PV array in real time. Even under cloudy conditions, partial shading, or when arrays face different directions, every PV input channel operates at its optimal performance. Compared to traditional single or dual MPPT solutions, energy yield can be improved by 5% to 15%.
Users simply connect solar panels directly to the system and achieve a complete solar-plus-storage loop. The system also supports simultaneous connection to the utility grid and diesel generators as supplementary energy sources – automatically switching between them during periods of low sunlight or emergencies to ensure uninterrupted power supply.
When the utility grid fails, the system automatically transitions to off-grid mode, independently supporting all connected loads. More critically, the built-in PV input channels remain fully operational in off-grid mode – meaning even when completely disconnected from the main grid, as long as sunlight is available, solar generation continues. Working in tandem with the battery, the system delivers a continuous stream of green power to factories, schools, water treatment plants, and other facilities. This is no longer a simple backup power source – it is a truly self-sufficient, autonomously operating microgrid.
Lingtech’s 103kWh/50kW Hybrid BESS supports simultaneous connection to three energy input sources: solar PV, the utility grid, and diesel generators.
When sunlight is abundant: PV generation takes priority, with excess power stored in the battery.
At night or during overcast conditions: The battery discharges to supply loads.
When battery levels run low: The system automatically starts the diesel generator for supplementary charging, or draws from the grid (if available).
When grid power is restored: The system seamlessly switches back to grid-tied mode.
All intelligent dispatch among the three energy sources is handled autonomously by the system – no manual intervention required.
Since its market debut in 2021, the product has been widely deployed across Europe, Africa, the Middle East, Southeast Asia, and South America. Its unique built-in MPPT design significantly reduces PV ancillary equipment costs and installation complexity for end users, making it particularly popular in the following scenarios:
Industrial Manufacturing: Steel mills, rice mills, quarries, and mines – ensuring continuous production and preventing costly downtime from grid instability.
Public Infrastructure: Water treatment plants, schools, libraries, and government buildings – keeping essential public services running without interruption.
Commercial Applications: Parking garages, small-to-medium factories, and shopping centers – leveraging peak shaving and time-of-use arbitrage to cut electricity costs.
Remote Areas: Off-grid villages, island communities, and telecom base stations – providing electricity access through independent microgrids.
Any Facility Requiring Uninterrupted Power: From hospitals to data centers, the system delivers reliable power protection for all critical loads.
