Description
Synchronized active and reactive power modulation across mega-plants.
SAJ eManager-C1 Pro is an industrial smart energy management controller managing up to 30 commercial inverters and storage stations, engineered for multi-megawatt plant telemetry, sub-second dynamic zero-export compliance, and automated industrial peak shaving.
Fleet-Wide 30-Inverter Coordination
Synchronizes telemetry and active/reactive power modulation across multi-megawatt commercial solar arrays.
Sub-Second Dynamic Zero-Export Control
Prevents unauthorized grid injection at sub-second intervals to comply with commercial utility connection rules.
Automated Peak Shaving & Energy Arbitrage
Schedules large battery charging during off-peak hours and discharges during peak industrial tariff windows.
Industrial Dual-Ethernet & 4x RS485 Ports
Multiple isolated communication channels ensure noise-immune industrial telemetry transmission across large switchyards.
More product details
Managing sprawling multi-inverter commercial installations requires fast, coordinated control loops to meet utility dispatch demands. The eManager-C1 Pro modulates power across 30 inverters synchronously.
- Multi-loop RS485 architecture coordinates dozens of inverters with sub-second response times.
- Real-time zero-export and custom power export caps enforced at the point of common coupling.
- Measures three-phase facility power via external 5 A split-core current transformers or digital smart meters.

Automated tariff arbitrage with industrial SCADA integration.
Managing large commercial storage containers requires smart dispatch algorithms to flatten factory demand charges. The eManager-C1 Pro automates multi-stage battery dispatch while bridging telemetry to central SCADA. Automated peak shaving logic discharges battery storage during expensive 15-minute peak demand windows. Dual Ethernet ports isolate factory automation networks from public internet telemetry channels. Modbus TCP protocol enables seamless integration into factory SCADA and building management systems.
Talks to web portals, apps, and local browsers
Plant operators access live telemetry via cloud web portals, mobile apps, or direct local web pages. Remote firmware updates execute over Ethernet, cellular links, or USB.
Fits tough environments from minus 25 to 60 °C
The 7.5 kg wall-mounted enclosure measures 300 x 400 x 170 mm. IP65 ingress protection seals sensitive electronics against dust and water jets.
Takes a 1 to 30 minute logging interval
Data collection interval is 1 to 30 minutes, 5 minutes standard. Firmware updates run over Ethernet, USB, or remote.
Technical data
Centralized plant power dispatch, dynamic zero-export, and multi-cabinet storage orchestration.
Commercial microgrid energy management controller managing up to 30 C&I inverters.
Engineered for large commercial solar plants, factory microgrids, and multi-cabinet storage systems, the eManager-C1 Pro coordinates up to 30 SAJ commercial inverters and battery stations (such as CH3, CM2, and CB3). It provides high-speed dynamic export control, reactive power compensation, and automated multi-tariff peak shaving without requiring custom PLC programming.
