| Product List |
The 1stess battery-buffered DC EV charging system combines grid access, LFP battery storage access and solar PV input in a configurable platform for commercial EV charging projects. Designed for importers, EPC contractors, charging operators and project procurement teams, it supports load shifting and coordinated energy use under a unified EMS strategy. Its specified electrical isolation separates grid, battery, EV and renewable-energy interfaces; final protection design is reviewed for the selected configuration.
The IHS540K2 Power Cube supports up to 360kW total EV charging output across a maximum of four charging points with two dual-connector dispensers. Its 150–1000V DC charging range supports project evaluation for different vehicle voltage requirements. Power is allocated within the configured system; 360kW is not a per-connector rating.
Energy storage access supports up to two LFP battery groups, specified at 200kWh per group. The source specification lists up to 120kW charging from the AC grid to storage and up to 240kW battery-to-EV output with the specified module configurations. PV access supports up to two 30kW MPPT channels. These are separate path limits and must not be added together as a promised simultaneous output.
Choose EXP200-FDC, EXP300-FDC or EXP500-LDC dispensers according to current, connector and site requirements. Dispenser features include a capacitive touchscreen, RFID, emergency stop, DC metering and OCPP 1.6J, with LAN and LTE modem support. Higher-current connections, bidirectional grid feedback, V2G and AC-bus backup require the corresponding options and engineering confirmation.
Send your available grid capacity, vehicle charging requirements, battery capacity, PV capacity and target-market connector standard. 1stess can help define the configuration for fleet depots, commercial parking and charging-hub projects.
Coordinate battery charging and EV demand through the system configuration and EMS strategy. Evaluate load shifting against your site's tariff, grid capacity and operating profile. Actual savings and charging availability depend on the selected system and usage.
The supplied feature list specifies electrical isolation between grid, battery, EV and renewable-energy inputs. Include the isolation and protection design in the project engineering review; the source does not establish target-market certification or an independently verified safety result.
Specify grid-to-storage, grid-to-EV and battery-to-EV requirements separately. This helps engineering teams assess module allocation and charging demand before procurement.
The platform supports a maximum of two battery groups at 200kWh each and up to two 30kW PV MPPT inputs. Battery capacity is an access specification, not a claim that 400kWh is installed inside the pictured Power Cube.
Compare the EXP200-FDC, EXP300-FDC and EXP500-LDC current options, cabinet depth, connector selection and project operating needs. System output and selected connector ratings determine the final charging capability.
The Power Cube has a 7-inch TFT touchscreen, five LED indicators and emergency stop. Dispensers feature a capacitive touchscreen behind tempered protective glass, two RGB panel LEDs, RFID, DC energy metering and emergency stop.

The source names the platform IHS540K2 540kW Power Cube, while the EV charging specification lists a maximum of 360kW. The 360kW rating is a shared system maximum, subject to configuration.
The Power Cube specification supports up to four charging points using two dual-connector dispensers. Output is allocated within the configured system limits and vehicle requirements.
The source specifies access for up to two 200kWh battery groups. It does not establish that 400kWh is built into the pictured cabinet. Battery scope and physical layout must be confirmed for each project.
The specified PV interface supports up to two 30kW MPPT channels. PV design and actual energy contribution depend on the selected configuration and site conditions.
No. The source lists these as optional functions dependent on the corresponding bidirectional converter configuration. Confirm the required function, grid rules and control strategy during engineering.
