Battery Energy Storage Systems (BESS)
Store excess solar power generated during the day, power your premises through nighttime hours, and protect your home or business against unpredictable grid blackouts with certified lithium battery storage.
Engineered Storage for Every Application
Whether you need 5 kWh of overnight residential backup or 2 MWh of industrial peak shaving, CitadelSolar connects you with certified battery specialists.
Residential Home Battery Storage
Seamless wall-mounted or rack-mounted lithium batteries delivering whole-home or essential-circuit backup during utility grid blackouts.
- 10ms transfer switch time
- LiFePO4 high-safety chemistry
- 10-year / 6,000+ cycle warranties
Commercial & Industrial BESS
High-voltage containerized battery energy storage systems engineered for maximum demand shaving, energy arbitrage, and factory microgrids.
- Liquid-cooled thermal management
- Automated peak demand shaving
- SCADA & frequency regulation
Retrofit & Battery Upgrades
Upgrade your existing grid-tied solar array by adding AC-coupled or DC-coupled high-voltage batteries without replacing your current inverter.
- AC-coupled retrofit inverters
- Smart energy management
- Modular expansion
Time-of-Use (TOU) Tariff Arbitrage
Automatically charge your battery during off-peak hours at cheap utility rates, and discharge power during expensive peak billing windows.
- Dynamic spot-price tracking
- Automated grid charging
- Maximized return on investment
Why We Exclusively Recommend LiFePO4
Lithium Iron Phosphate (LFP) has emerged as the definitive global standard for stationary solar storage, outperforming legacy cobalt-based chemistries and lead-acid batteries across safety, cycle longevity, and environmental footprint.
Lithium Iron Phosphate (LiFePO4)
Industry benchmark for safety, thermal stability, zero risk of thermal runaway, and 6,000 to 10,000 cycle lifespan.
High-Voltage (HV) Architecture
400V to 800V DC operating ranges minimizing transmission losses, smaller cable runs, and delivering higher continuous discharge power.
Modular Rack Scalability
Start with an entry 5 kWh module and seamlessly add battery modules in parallel or series as your household or business energy demands grow.
