Why this product

In short

Install-ready C&I storage in a standard 20-ft container: battery, PCS, cooling and fire suppression are integrated, pre-tested and pre-installed at the factory. String architecture (each battery cluster is managed independently), liquid cooling for the battery and air cooling for the inverter. This is the system behind our Pernik project and the basis of our offers for industrial sites above 1 MWh.

We supply, install and commission; every system gets free 24/365 monitoring and, with a Suntech battery of 261 kWh or more, the GrideX EMS with no licence fees.

Included for free

GrideX EMS: our open-source energy management system, free with every Suntech battery

Every client who buys a Suntech battery system from us receives, in addition and completely free, the GrideX Energy OS EMS – our own open-source energy management system (MIT licence, no licence fees). It schedules the battery against IBEX day-ahead prices, shaves peaks, forecasts production from the weather and keeps the battery inside its safety envelope.

  • Controls an unlimited number of external devices: inverters, batteries, EV chargers, loads (Modbus TCP/RTU, RS485, CAN, MQTT)
  • Works with Suntech, Deye, Sungrow, Huawei, Growatt, Fronius and more
  • 24/365 monitoring and SMS alerts via gridex.tech – free
  • Local edge gateway: decisions are made on site, even without internet
