Why this product

In short

The DC battery container with the highest energy density in the range: 5.015 MWh in a standard 20-ft enclosure with integrated packs, BMS, EMS, HVAC and fire suppression. Liquid cooling keeps cell temperature differences minimal, extending life and improving safety. For grid, generation and large industrial projects, paired with the PCS of your choice.

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
