How to Add Battery Storage to an Existing Solar System

Many factories and commercial buildings already have solar panels installed. However, without battery storage, excess solar energy may be exported to the grid or wasted through curtailment. Can you add batteries without replacing your existing solar inverters? In many cases, yes. 1. AC-Coupled ESS: Keep Your Existing Solar System One of the simplest ways to add battery storage is through AC coupling. System Architecture: Existing Solar Panels → Existing PV Inverters → AC Bus KOODSUN Battery → PCS → AC Bus AC Bus ↔ Factory Loads / Utility Grid This allows the existing solar system and the new ESS to work together. Main Benefits: Keep existing solar inverters Store excess solar energy for later use Reduce peak electricity demand Use stored energy during expensive electricity periods Support backup power when properly configured 2. Can the System Work During a Power Outage? Not automatically. Most conventional grid-tied solar inverters shut down when the utility grid fails. If backup power is required, the system may need a grid-forming PCS, EMS, switching and protection equipment, and compatible existing PV inverters. The complete system must be evaluated to ensure safe operation during a blackout. 3. What If You Want to Add More Solar Panels? If you plan to expand both solar and battery capacity, a hybrid solution may be suitable. For example: Existing PV → Existing Grid-Tied Inverters → AC Bus New PV + Battery → Compatible Hybrid Inverter → AC Bus This combines AC coupling with DC-side solar and battery integration. 4. How Do You Choose the Right Battery Capacity? Battery capacity should be based on actual electricity consumption, not simply on existing solar capacity. For example, a factory with 400kWp solar panels does not necessarily need a 400kWh or 1MWh battery. The correct ESS size depends on: Maximum load (kW) Daily electricity consumption (kWh) Daytime and nighttime energy usage Available excess solar generation Required backup hours Electricity tariffs and grid conditions These factors help determine the appropriate PCS power (kW) and battery capacity (kWh). 5. KOODSUN ESS Solutions KOODSUN provides high-voltage lithium batteries, outdoor C&I ESS cabinets and containerized BESS solutions for commercial and industrial applications. Whether you want to increase solar self-consumption, reduce electricity costs or add backup capability, we can help evaluate a suitable ESS configuration. Already Have Solar? Let's Add Storage.

500kW Solar + 1.2MWh Energy Storage Project in Germany

KOODSUN has delivered a 500kW solar + 1.2MWh battery energy storage project in Germany, combining rooftop photovoltaic generation with a containerized BESS for commercial and industrial energy use. The project integrates solar generation and battery storage to help the customer increase solar energy utilization, improve energy flexibility, and better manage electricity consumption. Project at a Glance Location: Germany Application: Commercial & Industrial Solar Capacity: 500kW Battery Storage: 1.2MWh Battery Type: LiFePO4 Storage Solution: Containerized BESS System Type: Solar + Energy Storage Solution Provider: KOODSUN 500kW Solar Power for Industrial Energy Demand The project is equipped with a 500kW rooftop solar system, allowing the customer to generate electricity directly from solar energy during the daytime. For commercial and industrial facilities, daytime electricity demand can be significant. Rooftop solar can supply part of this demand directly and reduce the amount of electricity drawn from the grid. However, solar generation and actual electricity consumption do not always occur at exactly the same time. This is why battery storage was integrated into the project. 1.2MWh Containerized Battery Energy Storage The project includes a 1.2MWh LiFePO4 battery energy storage system installed in a containerized configuration. The BESS allows available solar energy to be stored and used later according to the site's actual operating requirements. Depending on the energy management strategy, the battery can support applications such as: Increasing solar self-consumption Peak shaving Load shifting Reducing grid electricity consumption during selected periods Improving overall energy flexibility For a project of this scale, the containerized design provides a centralized and practical solution for integrating MWh-level battery storage into an industrial site. Solar and Battery Storage Working Together The key value of this project is the combination of 500kW solar generation and 1.2MWh battery storage. During periods of sufficient sunlight, solar energy can directly support the site's electrical loads. When solar generation exceeds immediate demand, available energy can be stored in the BESS. The stored electricity can then be discharged later when solar production decreases or when the site's energy management strategy requires battery support. In this way, the customer can make better use of the electricity generated by the rooftop PV system rather than relying only on real-time solar production. A Practical Solar + Storage Solution for C&I Applications Commercial and industrial facilities have very different electricity consumption patterns. Production schedules, peak demand, daytime and nighttime consumption, electricity tariffs and grid conditions can all influence the appropriate system configuration. Therefore, C&I ESS projects should be designed according to the actual energy requirements of the site. For this project in Germany, the combination of 500kW solar + 1.2MWh BESS provides the customer with a more flexible way to manage solar generation and electricity consumption. KOODSUN C&I Energy Storage Solutions This German project is another example of KOODSUN's solar + storage solutions for commercial and industrial applications. KOODSUN provides a range of ESS solutions, including: High-voltage battery systems, outdoor C&I ESS cabinets, containerized BESS, PCS + BESS solutions, and complete solar + storage systems.
