Commercial & Industrial Energy Storage Solutions (C&I BESS)
DJENERGY delivers all-in-one air-cooled commercial & industrial energy storage solutions for PV + grid + diesel hybrid sites. Use BESS for peak shaving, TOU shifting, backup power and zero export compliance. Modular cabinets support parallel expansion and fast commissioning.
Commercial & Industrial BESS
Designed for peak shaving, TOU shifting, PV self-consumption and backup power for C&I sites.
- Peak shaving & TOU shifting to cut electricity bills
- Backup for critical loads (STS/ATS-ready)
- EMS-ready operation with remote monitoring options
- Factories, warehouses, and industrial parks
- Commercial buildings, malls, and data/telecom facilities
- Sites with high demand charges or TOU tariffs
- Scheduled charging/discharging (TOU arbitrage)
- Peak shaving / demand limiting
- Backup mode with seamless transfer (with STS/ATS)
- Works with existing PV inverters (AC-coupled)
- Supports common LV standards (400V 50Hz / selected 480V 60Hz)
- Commissioning checklist and documentation set available
Off-Grid Hybrid (PV + DG + BESS)
Stable power for remote sites—maximize PV usage and reduce diesel fuel consumption.
- PV-first dispatch with generator support when needed
- Fuel-saving operation with optimized charging strategy
- Reliable power for critical loads in weak-grid / no-grid sites
- Remote factories, mining, oil & gas camps
- Islands and rural communities
- Construction sites and temporary power
- PV priority + battery buffering
- Generator start/stop logic based on SOC and load
- Load management for critical vs non-critical circuits
- AC-coupled architecture supported (PV inverter + PCS)
- Can coordinate with diesel genset controller (start/stop, limits)
- Recommend site load profile and generator rating for sizing
Zero Export Control
Meter-based export limiting to keep export at 0 kW while maximizing self-consumption.
- Meter-based export limiting (0 kW export)
- Increase PV self-consumption and reduce curtailment
- Compatible with common grid compliance requirements
- Sites with “no feed-in” policies or limited export contracts
- Commercial facilities adding PV without grid upgrade
- Industrial users needing strict export compliance
- Real-time power control based on grid meter readings
- Export cap = 0 kW (or configurable limit if allowed)
- PV + BESS coordination to absorb surplus generation
- Requires CT/meter at point of common coupling (PCC)
- Works with AC-coupled PV; control logic managed by PCS/EMS
- Recommend single-line diagram review before installation
Microgrid Solution
Coordinate PV, storage, and generators with centralized control for stable and efficient operation.
- Multi-source coordination (PV + BESS + DG + grid optional)
- Improved power quality and load stability
- Scalable architecture for community / campus microgrids
- Campuses, industrial parks, and island grids
- Community power systems and utility-supported microgrids
- Critical infrastructure with high uptime requirements
- Priority dispatch rules (PV-first / cost-first / reliability-first)
- Frequency/voltage support (project-dependent)
- Black-start / system restoration logic (if required)
- Recommend a site-level EMS for multi-unit coordination
- Grid-forming capability depends on PCS configuration (project-based)
- Provide interface list for SCADA / BMS / meters as needed

FAQ
What size C&I BESS do I need for peak shaving?
Provide peak demand (kW), target reduction (kW), and duration (hours). We size power (kW) for demand control and energy (kWh) for runtime.
Can your system work with PV + grid + diesel together?
Yes. Our EMS supports PV priority, grid interaction, and diesel coordination for hybrid and weak-grid sites.
Do you support zero export / export limiting?
es. Meter/CT feedback enables 0 kW export or a configurable export cap through EMS/PCS real-time control.
Is AC-coupled PV supported?
Yes. AC-coupled PV integration is commonly used for retrofits and hybrid applications.
Can I expand later?
Yes. Systems support parallel expansion to increase kW/kWh as loads grow.
What information do you need for a quotation?
Grid voltage/frequency, PV size, load profile, target application (peak shaving/backup/zero export), and installation environment.
