What Are Solar-Compatible Energy Storage Systems?

Solar-compatible energy storage systems are battery-based solutions that capture excess solar energy generated during daylight hours and release it during periods of low sunlight, such as at night or during inclement weather. These systems are essential for maximizing the use of solar energy, ensuring consistent power supply, and reducing reliance on the utility grid.

Paired with solar photovoltaic (PV) panels, these systems enable energy users—ranging from households to industrial plants—to achieve greater energy independence, improved energy cost savings, and enhanced grid resilience.

Types of Energy Storage Systems for Solar Integration

1. Residential ESS Solutions

• Capacity Range: 5kWh to 80kWh

• Configurations: Stackable modules, wall-mounted units, or rack battery cabinets

• Suitable for: Homes, villas, and off-grid residences

2. Commercial & Industrial ESS

• Capacity Range: 100kWh to 500kWh+

• Designed for: Factories, commercial buildings, warehouses, and farms

• Functions: Peak shaving, backup power, TOU optimization

3. Utility-Scale Containerized ESS

• Capacity Range: 1MWh to 5MWh+

• Integrated with: PV plants, microgrids, EV charging hubs

• Modular design for scalability

4. All-in-One PV + ESS Systems

• Combines: Solar inverter, lithium battery, and EMS in a single cabinet

• Benefits: Fast installation and centralized energy control

Dagong ESS provides both air-cooled and liquid-cooled configurations across all product levels.

Key Features of Solar ESS Solutions

• PV Integration: Compatible with both off-grid and grid-tied solar inverters

• Smart Energy Management: Optimized charge/discharge via intelligent EMS

• Time-of-Use Arbitrage: Charge with solar, discharge during high tariff periods

• Emergency Backup: Ensures stable electricity during blackouts

• Modular Expansion: Scalable systems allow flexible upgrades

• International Certification: Products comply with CE, UN38.3, MSDS, 3C, and IEC standards

Applications of ESS in Solar Projects

• Remote residences and off-grid cabins

• Rooftop solar homes with backup storage

• Farms and greenhouses using solar power

• Commercial buildings with PV and battery integration

• Solar-powered EV charging stations

• Community microgrids and utility-scale PV farms

Price of Solar-Compatible Energy Storage Systems

The cost of a solar ESS depends on several factors, including:

• Storage capacity (from 100kWh to over 5MWh)

• Cooling technology (air vs. liquid)

• System integration requirements (PV, EMS, grid connection)

Air-cooled ESS cabinets (100–241kWh) are economical for mid-sized users. Liquid-cooled containers (215kWh–5MWh) are better suited for large-scale operations. Pricing follows standard international terms such as EXW, FOB, or CIF, based on the customer’s location and delivery preferences.

How Long Do Solar ESS Systems Last?

Dagong ESS uses premium lithium iron phosphate (LFP) batteries, delivering:

• Over 8,000 cycles at 70% State of Health (SOH)

• Service life of 15+ years with proper maintenance

• Stable performance when paired with EMS and thermal control systems
