System solutions, delivered by scenario
PV, storage, power and charging products can be sourced individually or assembled into a complete system. We provide selection lists, topology recommendations and interface coordination to reduce the number of parties an EPC or integrator has to manage.
C&I solar-plus-storage
High-efficiency modules on the factory roof feed string inverters into the site distribution board. Storage cabinets charge and discharge automatically against time-of-use tariffs and demand data — absorbing PV by day, discharging at night or during peaks — cutting energy cost and relieving transformer capacity.
- ✓Generation: DJ-PV110 / DJ-PV350 + N-type bifacial modules + smart combiner boxes
- ✓Storage: DJ-ESS261 liquid-cooled cabinets, paralleled for capacity
- ✓Dispatch: EMS scheduling from tariff curves, load forecasts and SOC
- ✓Optional: grid-connection panel, metering and remote O&M integration
Utility-scale BESS
20-ft liquid-cooled containers are the building block; multiple units are paralleled through PCS and step-up transformers into the grid. Suited to renewable co-location, standalone storage, frequency regulation and peak shifting. Each container integrates BMS, liquid cooling, combustible gas detection and zoned fire suppression.
- ✓5.015 MWh per container, 314 Ah LFP cells, 1331.2 Vdc nominal
- ✓Charge / discharge up to 2.5 MW per container, multi-container expansion
- ✓Liquid cooling with in-pack temperature control and multi-level alarms
- ✓Ethernet / CAN / Modbus interfaces for station-level SCADA
Urban supercharging & highway service areas
Power modules are centralised in a charging cabinet and allocated dynamically to each bay terminal by the power distribution unit. High-demand vehicles draw concentrated power; low-demand vehicles share the remainder — avoiding the capacity waste of fixed per-gun power. Adding storage further trims grid upgrade and demand charges.
- ✓DJ-SC800 all-liquid-cooled cabinet, 12 outputs standard, 150–1000 Vdc
- ✓600 A liquid-cooled single-gun, or liquid plus air-cooled dual-gun terminals
- ✓Backward compatible with legacy GB/T vehicles, backend platform ready
- ✓Optional storage cabinets for peak shaving, reducing transformer investment
Microgrid & off-grid supply
For remote sites, islands, temporary camps and overseas projects, PV, storage and grid or diesel generation combine into a multi-source system. On-grid and off-grid modes are both supported, and modular equipment simplifies container shipping and staged on-site expansion.
- ✓Seamless on-grid / off-grid transfer, uninterrupted supply to critical loads
- ✓Bidirectional PCS with microgrid controller balancing power and SOC
- ✓Modular configuration, capacity expanded in stages as the site grows
- ✓Remote monitoring, fault alarms and operational data export
A typical PV · storage · charging energy flow
Each block can be included or omitted per project; interfaces and protocols are aligned once, at design stage.
This is an indicative topology. Actual wiring, protection and metering follow the project primary / secondary design drawings.
Configuration quick reference
Core models and key considerations by scenario, for early-stage sizing.
| Application | Core models | Typical capacity / power | Key considerations |
|---|---|---|---|
| C&I solar + storage | DJ-PV110 + DJ-ESS261 + EMS | 100 kW–2 MW / from 261 kWh | TOU tariff, demand management, roof orientation |
| Utility-scale BESS | DJ-ESS5M + DJ-PCS215 | 5.015 MWh per container, multi-container | Grid dispatch, fire suppression & thermal control, cycle life |
| Urban liquid-cooled supercharging | DJ-SC800 + DJ-SC600 + DJ-PDU | 600 / 800 kW cabinets | Power allocation, grid capacity, vehicle compatibility |
| Microgrid & off-grid | DJ-PCS215 + DJ-ESS-H / ESS261 | Customised to load | On/off-grid transfer, transport, on-site expansion |
| Equipment / OEM | DJ-ACDC40 / 30 + DJ-DCDC | 30 / 40 kW module level | Interface protocol, cooling method, form factor |
