BATTERIES
BATTERIES WHY THEY MATTER NOW
By integrating battery storage, the carport is transformed into a smart energy hub that captures solar energy, stores excess power, and efficiently distributes it to charging stations for electric vehicles, homes, or commercial buildings. A solar carport is no longer just a protective structure for vehicles—it becomes a decentralized power plant. Instead of passively consuming energy, your parking space actively generates, stores, and optimizes it.
Rising energy prices, grid instability, and electrification
From parking garage to energy source
Electricity markets are becoming increasingly volatile, with fluctuating kWh prices and growing grid constraints. Battery storage provides stability in an unstable environment. It enables users to store energy when prices are low and use it when prices rise, while also protecting against outages and power curtailments. 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 feeding it into the grid at low or unstable prices. This significantly increases the self-consumption rate—typically from about 30% to more than 70%—allowing more of the locally produced green electricity to be used directly in the home or to charge electric vehicles. As a result, households reduce their dependence on volatile electricity prices, lower their energy bills, and gain greater control over when and how their energy is used.

BACKUP POWER POWER OUTAGE PROTECTION
In the event of a power outage, our system ensures a seamless transition from grid-connected operation to off-grid mode. A dedicated gateway automatically disconnects the site from the public power grid, allowing the battery and the solar-powered carport to continue supplying power safely and reliably. Critical loads such as heating, cooling, internet connectivity, and electric vehicle charging remain operational, ensuring comfort, safety, and continuity even during extended power outages.

AI-Driven Energy Optimization
Sigenergy’s 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 it when prices are high. This intelligent automation maximizes savings without requiring user intervention, ensuring that energy is used at the most cost-effective time while maintaining comfort and reliability.

PEAK POWER LIMIT GRID RATE
Many electricity rates are based not only on energy consumption (kWh), but also on the peak power demand (kW) reached during a billing period. A battery storage system helps limit these peaks by supplying short-term high loads directly, rather than drawing them from the grid. By reducing the maximum power demand, homeowners can avoid expensive peak surcharges and unfavorable grid rates associated with high kW consumption. The result is a smoother, more predictable energy profile and significantly lower total electricity costs.

BIDIRECTIONAL CHARGING VEHICLE INTEGRATION (V2H / V2G)
Two-way charging turns your electric vehicle into an additional energy storage asset. With Vehicle-to-Home (V2H), the energy stored in your electric vehicle can be used to power your home during peak hours or power outages, increasing self-consumption and resilience. Vehicle-to-Grid (V2G) takes it a step further by allowing the electric vehicle to feed energy back into the grid, which helps stabilize the grid while generating additional revenue through flexibility services. This future-proof infrastructure ensures compatibility with next-generation electric vehicles and places your home or business at the center of the evolving energy system.
LARGE BATTERY SOLUTION

LARGE SOLAR SURPLUS INSTEAD OF EXPORTING AT LOW PRICES
Battery storage enables businesses to capture excess solar energy generated on-site rather than feeding it into the grid at low or fluctuating prices. By storing excess production for later use, businesses reduce energy costs and significantly improve the return on investment in their solar installations. This approach increases energy efficiency while providing greater cost predictability in an increasingly volatile energy market.

ENABLES HIGH-EFFICIENCY CHARGING OF ELECTRIC VEHICLES WITHOUT REINFORCING THE GRID
High-power chargers for electric vehicles often require large grid connections, leading to costly upgrades and lengthy approval processes. A battery system acts as a power buffer, meeting peak charging demand while limiting the required grid capacity. This enables the expansion of fast-charging infrastructure for electric vehicles without expensive grid reinforcement, accelerating project timelines and reducing initial investments.
BUSINESS CONTINUITY AND BACKUP POWER
MICROGRIDS AND ON-SITE ENERGY MANAGEMENT
ONLINE SERVICES AND NEW REVENUE STREAMS
REGULATORY COMPLIANCE AND ESG PERFORMANCE
Power outages can disrupt operations, damage equipment, and result in significant financial losses. Battery storage ensures continuity by enabling a seamless transition to islanded operation of microgrids in the event of a grid failure. Critical systems remain powered, sensitive equipment is protected, and business operations can continue without interruption.
By integrating solar power generation, battery storage, electric vehicle chargers, and building loads into a smart system, companies create a robust on-site microgrid. Advanced energy management software optimizes energy flows in real time, maximizing efficiency and minimizing costs. The result is a self-sufficient energy ecosystem that can operate independently when needed.
Large-scale battery systems can participate in grid support markets such as frequency control reserve (FCR) and other ancillary services. By providing rapid balancing capacity, companies can generate new revenue streams while supporting grid stability. Containerized BESS solutions can be specifically designed for market participation.
Battery storage supports companies’ sustainability strategies by increasing the use of renewable energy and reducing carbon emissions. It helps companies meet regulatory requirements, energy efficiency targets, and reporting obligations. At the same time, it strengthens ESG performance, enhances the company’s reputation, and demonstrates leadership in the energy transition.
