An energy storage system 50kW is a commercial-scale solution. It is designed to store excess solar energy. It releases this energy during peak demand periods. GRANKIA BESS-50-120K integrates a 50kW hybrid inverter with a 120kWh LiFePO4 battery. This integration enables businesses to reduce electricity costs through solar peak shaving and energy optimization.
This system stores excess photovoltaic generation during the day. It discharges the stored energy during high-demand periods. This ensures that your facility operates at peak efficiency. It also significantly reduces electricity costs.
Unlike generic storage units, the 50kW battery storage system is engineered for mid-sized commercial buildings. It is ideal for EV charging hubs and manufacturing facilities. These facilities seek reliable peak shaving and load shifting.

Key Features of Energy Storage System 50kW
Substantial Energy Capacity
With a nominal capacity of approximately 120kWh, this unit offers extended backup duration. It has significant load-shifting capabilities. This ensures operations continue smoothly even when solar generation is low.
Advanced Solar Peak Shaving
Utilizing intelligent algorithms, the system automatically detects peak tariff windows. It discharges stored energy to offset grid usage, effectively executing solar peak shaving to minimize demand charges and time-of-use costs.
Seamless Hybrid Integration
Designed as hybrid inverter system, it manages the flow of energy between solar panels, the battery, and the grid. This system operates simultaneously, maximizing self-consumption of renewable energy.
Scalable & Modular Design
The cabinet design allows for flexible deployment. Multiple units can be connected in parallel. This configuration creates a high-capacity energy storage farm. It can scale up to megawatt-hour levels for larger industrial complexes.
Smart Battery Management (BMS)
An integrated BMS ensures safety and longevity by monitoring cell voltage, temperature, and state of charge (SOC) in real-time. It prevents overcharging and optimizes the lifecycle of the LiFePO4 battery cells.
Grid-Independent Operation
In the event of a utility failure, the system switches to island mode within milliseconds. It provides a reliable grid-independent power supply to critical loads without interruption.
Real-Time Monitoring
Users can access a cloud-based monitoring platform to track energy flows, system health, and savings data remotely. This access facilitates data-driven demand charge reduction strategies.

How the Energy Storage System 50kW Enables Solar Peak Shaving
Peak shaving means reducing electricity consumption from the grid during expensive demand periods. Here’s how this energy storage system 50kW works:
-
Solar Charging: During low-tariff hours (e.g., 9 AM – 2 PM), the system stores excess solar generation.
-
Smart Discharge: When utility rates peak (e.g., 4 PM – 9 PM), the BESS-50-120K automatically discharges stored solar energy to power your facility.
-
Demand Limit: It never draws more than a preset grid limit, eliminating demand spikes.
-
Grid Backup: If grid fails, the system island-mode powers critical loads.
