St-ems supplies the wattsonic hybrid storage platform for residential and small commercial PV sites that combine rooftop solar with battery storage. The wattsonic system integrates PV input, battery, and grid connection into a single hybrid unit, and it exposes its data over Modbus as three logical register blocks — battery, grid, and PV — matching how an installer actually thinks about the installation.
ModbusCloud templates mirror this structure for St-ems. You read PV generation power, battery state of charge, battery charge and discharge power, and grid import and feed-in over Modbus without chasing addresses through a specification document. Live values flow into your portal, historical data supports yield and self-consumption reports, and you set alerts on SOC thresholds, feed-in drops, or inverter faults across all St-ems installations you manage.
All St-ems templates are free to browse. Import the battery, grid, or PV template into your ModbusCloud portal and read live data within minutes — no register mapping, no manufacturer PDFs.
