How Our C&I Energy Storage System Works

125kw 261kwh C&I ESS system working principle diagram PV PCS battery load energy flow chart

01 · PV Generation & AC/DC Conversion

Photovoltaic panels generate DC solar power. The bidirectional PCS completes AC-DC power conversion, and energy is stored in LiFePO4 battery banks.

02 · Peak-Shaving Discharge & Backup Power

During high-tariff peak periods or grid failure, the stored energy discharges to supply factory and commercial loads. This delivers peak-valley arbitrage, demand-charge reduction and uninterrupted backup power for your facility.

Typical Application Scenarios

Commercial industrial energy storage applied in manufacturing factory production site

Factory & Manufacturing Plant

Peak-valley arbitrage plus demand-charge control for production lines. The system shaves peak load, cuts maximum demand charges and keeps critical equipment running through grid disturbances.

LiFePO4 C&I ESS provide UPS backup power for data center critical IT equipment

Data Centre

Reliable UPS-grade backup power for critical IT infrastructure. Instant switchover protects servers and network equipment from outage-related downtime and data loss.

Frequently Asked Questions About C&I Energy Storage

C&I energy storage helps business users realise peak-valley arbitrage, reduce demand charges, provide emergency backup power and improve the self-consumption rate of on-site solar PV systems. It is widely used for factories, warehouses, commercial buildings and industrial parks.

Required capacity depends on your maximum load, local electricity tariff rules and target functions. Our engineers can offer a capacity suggestion after you provide your site load data.

Payback is mainly affected by the local electricity price difference, site load profile and system scale. In most Southeast Asia markets, the payback period ranges from 3-6 years.

Yes. Our C&I ESS can connect with existing PV installations to build solar-storage hybrid systems without replacing your current solar panels.

We provide remote technical guidance, an operation manual, spare parts support and local partner-assisted on-site commissioning service for overseas commercial & industrial energy-storage projects.
