Batteries are the backbone of hybrid power systems. They store excess solar energy produced during the day and discharge it when sunlight is unavailable or demand exceeds real-time solar output. In a solar-diesel hybrid system, batteries also minimize generator runtime by reducing the need for backup during minor load fluctuations.
Battery Roles in a Hybrid Setup
- Energy Storage: Store solar energy for use at night or during cloudy periods
- Peak Shaving: Supply power during high-demand moments, reducing generator or grid reliance
- Backup Support: Maintain critical load supply during power interruptions
Key Battery Parameters
Jubaili Bros designs each system with careful consideration of:
- Capacity (kWh): Total energy the battery can store
- Depth of Discharge (DoD): Maximum safe level of discharge—typically 80% for lithium-ion
- Cycle Life: Number of charge-discharge cycles the battery can perform reliably
- Round-Trip Efficiency: Energy retained after each full cycle
Battery Technologies We Support
- Lithium-Ion: High energy density, fast charging, long lifespan, ideal for performance-critical systems
- Lead-Acid (AGM/GEL): Cost-effective for small-to-medium installations, lower DoD and shorter lifespan
Smart Battery Management
Battery Management Systems (BMS) are critical for safety and performance. These systems monitor temperature, charge/discharge rates, and voltage per cell. They ensure batteries operate within optimal parameters and integrate seamlessly with hybrid inverters.
Environmental and Economic Benefits
Batteries enable reduced generator fuel consumption and allow for energy arbitrage in grid-connected scenarios (charging during low tariff hours and discharging during peak rates). With rising fuel costs, battery-backed systems provide excellent long-term savings and ROI.
