Systèmes BESS SOFAR CBS5000 & CBS8000 : l’atout pro face aux tarifs dynamiques

SOFAR BESS systems: a strategic response to dynamic pricing

With the widespread adoption of dynamic electricity pricing and increasing grid volatility, businesses need to rethink their energy management. SOFAR's Battery Energy Storage Systems (BESS), available from Wattuneed, offer a reliable, cost-effective and scalable solution for storing, managing and maximising energy.

SOFAR CBS5000: modularity for performance

CBS5000 systems combine BMU (Battery Module Unit) and BCU (Battery Control Unit) modules to create cabinets ranging from 20 to 240 kWh. Thanks to their stackable, wiring-free design, IP66 rating and integrated heating, these batteries guarantee quick installation and stable operation, even in extreme conditions:contentReference[oaicite:0]{index=0}:contentReference[oaicite:1]{index=1}:contentReference[oaicite:2]{index=2}.

Each 5.12 kWh BMU module is based on lithium iron phosphate (LiFePO₄) chemistry, renowned for its longevity and safety. The BCU actively manages the balance between modules and enables automatic power ramp-up.

Key benefits for professionals

• Modularity: expansion up to 240 kWh with 4 racks in parallel.
• Safety: multi-level architecture, IP66, active balancing.
• Simplified maintenance: stackable design, automatic diagnostics.
• Compatibility: CAN communication with SOFAR hybrid inverters.

SOFAR CBS8000: turnkey industrial storage

The CBS8000 is designed for tertiary sites, SMEs and collective infrastructures requiring increased power and autonomy. Each cabinet offers 64 to 96 kWh of storage and up to 48 kW of charge/discharge power, for a total of 384 kWh in parallel:contentReference[oaicite:3]{index=3}.

Ready to use, this system is pre-installed in the factory and equipped with cloud monitoring. Its dual fire protection and corrosion resistance (C4) make it an ideal solution for demanding environments.

"Since installing our CBS8000, we have offset peak tariffs in less than six months. The investment pays for itself through energy arbitrage." — Wattuneed partner company

Key features of the CBS8000

• Pre-wired and ready to install
• Modular power up to 384 kWh
• Remote monitoring and intelligent balancing
• Quiet and robust operation (≤65 dB)

SOFAR HYD-40-60K-T1 hybrid inverter: the perfect complement

The inverter plays a central role in getting the most out of a BESS. The SOFAR HYD-40-60K-T1 combines up to 120 kWp of photovoltaic power and 60 kW of storage. Its native compatibility with CBS5000 and CBS8000 batteries enables intelligent grid control and optimal use of off-peak hours:contentReference[oaicite:4]{index=4}.

• 98.2% efficiency
• IP66 protection and AFCI IA
• 100% unbalanced three-phase load support
• PV overcapacity up to 200%

Maximise storage value in the face of dynamic pricing

Businesses equipped with a BESS system can store solar energy during off-peak hours and release it when hourly rates rise. This mechanism, known as energy arbitrage, reduces electricity bills by up to 40% depending on consumption patterns. At the same time, it increases energy resilience in the event of a grid outage.

Combined with a dynamic contract, BESS allows you to:

• resell energy during peak periods;
• stabilise the internal grid for critical loads;
• and optimise the lifespan of the photovoltaic park.

"Energy storage systems are becoming a strategic lever for any company seeking to regain control of its costs and autonomy." — Wattuneed Expert

FAQ

What is a BESS system?

A BESS (Battery Energy Storage System) stores electricity and releases it according to the site's needs, improving energy flexibility.

Why is BESS cost-effective with dynamic pricing?

It allows stored energy to be consumed when electricity prices are high and charged when they are lower.

What is the difference between CBS5000 and CBS8000?

The CBS5000 is modular (20 to 240 kWh) for SMEs, while the CBS8000 is turnkey (64 to 384 kWh) for industrial sites.

Are SOFAR BESSs compatible with other brands of inverters?

Yes, via CAN communication, but the best integration is achieved with SOFAR HYD inverters.

What maintenance is required?

The systems are autonomous and monitored remotely; an annual check is sufficient to guarantee their performance.
