ENERGY STORAGE
BATTERIES
WHY THEY MATTERS NOW
By integrating battery storage, the carport transforms into an intelligent energy hub that captures solar production, stores surplus energy, and distributes it efficiently to EV chargers, homes, or commercial buildings. A solar carport is no longer just a protective structure for vehicles — it becomes a decentralized power plant. Instead of consuming energy passively, your parking space actively generates, stores, and optimizes it.
Rising energy prices, grid instability, and electrification
From parking structure to energy asset
Electricity markets are becoming increasingly volatile, with fluctuating kWh prices and growing grid constraints. Battery storage provides stability in an unstable environment. It allows users to store energy when prices are low and use it when prices rise, while also protecting against outages and power limitations. The result is greater cost predictability, improved energy security, and reduced dependence on the public grid.

The result is greater cost predictability, improved energy security, and reduced dependence on the public grid.
MAXIMIZE SELF-CONSUMPTION LOWER ENERGY BILLS
By adding battery storage to a solar carport, private homeowners can store excess solar energy instead of exporting it to the grid at low or uncertain prices. This significantly increases the self-consumption rate — typically from around 30% to more than 70% — allowing more of the locally produced green electricity to be used directly in the home or for EV charging. As a result, households reduce their reliance on volatile electricity prices, lower their energy bills, and gain greater control over when and how their energy is used.
BACKUP POWER
BLACKOUT PROTECTION
In the event of a grid outage, our system ensures a seamless transition from grid-connected operation to island mode. A dedicated gateway automatically disconnects the site from the public grid, allowing the battery and solar carport to continue supplying power safely and reliably. Essential loads such as heating, refrigeration, internet connectivity, and EV charging remain operational, providing comfort, security, and continuity even during extended power failures.
AI - DRIVEN ENERGY OPTIMIZATION
Sigenergy advanced energy management enables smart charging and discharging based on real-time electricity price forecasts. By leveraging time-of-use optimization and dynamic tariffs, the system automatically charges the battery when electricity prices are low and discharges when prices are high. This intelligent automation maximizes savings without requiring user intervention, ensuring that energy is used at the most economically advantageous moment while maintaining comfort and reliability.
PEAK POWER LIMITATION
GRID TARIFF
Many electricity tariffs are not only based on energy consumption (kWh), but also on the highest power demand (kW) reached during a billing period. A battery energy storage system helps limit these peaks by supplying short-term high loads directly, instead of drawing them from the grid. By reducing maximum power demand, homeowners can avoid expensive peak demand charges and unfavorable grid tariffs linked to high kW usage. The result is a smoother, more predictable energy profile and significantly lower overall electricity costs.
BIDIRECTIONAL CHARGING
VEHICULE INTEGRATION (V2H / V2G)
Bidirectional charging transforms your electric vehicle into an additional energy storage asset. With Vehicle-to-Home (V2H), the energy stored in your EV can be used to power your home during peak hours or grid outages, increasing self-consumption and resilience. Vehicle-to-Grid (V2G) goes one step further by allowing the EV to feed energy back into the grid, helping stabilize the electricity network while generating additional revenue through flexibility services. This future-ready infrastructure ensures compatibility with next-generation EVs and positions your home or business at the center of the evolving energy system.
LARGE BATTERY SOLUTION
Store Solar Surplus Instead of Exporting at Low Prices
Battery storage allows companies to capture excess solar energy produced on-site instead of exporting it to the grid at low or fluctuating prices. By storing surplus production for later use, businesses reduce curtailment and significantly improve the return on investment of their PV installations. This approach increases energy autonomy while providing greater cost predictability in an increasingly volatile energy market.
Enable High-Power EV Charging Without Grid Reinforcement
High-power EV chargers often require large grid connections, leading to costly upgrades and long approval processes. A battery system acts as a power buffer, supplying peak charging demand while limiting the required grid capacity. This enables the deployment of fast EV charging infrastructure without expensive grid reinforcement, accelerating project timelines and reducing upfront investment.
Business Continuity & Backup Power
Power outages can disrupt operations, damage equipment, and lead to significant financial losses. Battery storage ensures continuity by enabling a seamless transition to islanded mini-grid operation during grid failures. Critical systems remain powered, sensitive equipment is protected, and business activities can continue without interruption.
Microgrids & On-Site Energy Management
By integrating solar production, battery storage, EV chargers, and building loads into one intelligent system, businesses create a resilient on-site microgrid. Advanced energy management software optimizes energy flows in real time, maximizing efficiency and minimizing costs. The result is a self-sustaining energy ecosystem capable of operating independently when needed.
Grid Services & New Revenue Streams
Large-scale battery systems can participate in grid support markets such as Frequency Containment Reserve (FCR) and other ancillary services. By providing fast-response balancing capacity, companies can generate new revenue streams while supporting grid stability. Containerized BESS solutions can be sized specifically for market participation.
Regulatory Compliance & ESG Performance
Battery storage supports corporate sustainability strategies by increasing renewable energy utilization and reducing carbon emissions. It helps businesses meet regulatory requirements, energy efficiency targets, and reporting obligations. At the same time, it strengthens ESG performance, enhances corporate reputation, and demonstrates leadership in the energy transition.
