SunSpec is an open information model for solar inverters, energy storage, meters, and environmental sensors. Rather than a manufacturer, SunSpec defines a standardised set of Modbus register models (103 Three Phase Inverter, 111/112 Float Inverters, 120 Nameplate, 122 Measurements & Status, 123 Immediate Controls, 124 Storage, and more) that many hardware vendors implement. If your device carries the SunSpec label, these templates give you a drop-in configuration without digging through vendor-specific register maps.
ModbusCloud ships ready-made templates for the full SunSpec model family so you can read nameplate data, live AC and DC measurements, status flags, storage state, and basic settings over Modbus. Whether the device speaks Modbus TCP over Ethernet or RTU over RS485, pick the SunSpec model that matches the firmware and the register addresses, scaling factors, and data types are already mapped. That matters for fleets where installers meet mixed hardware but want one consistent dashboard.
All SunSpec templates are free to browse. Import the model that matches your device into your ModbusCloud portal and read live data within minutes — no register mapping, no combing through SunSpec specification PDFs.
What you can read out
- AC active power and energy totals
- DC voltage, current, and power
- Inverter operating state and event flags
- Battery state of charge and storage limits
- Nameplate ratings and device identification
Typical installations
- Mixed-vendor PV fleets standardised on SunSpec-compliant inverters and meters
- Commercial storage sites where operators need one register model across hardware
- Retrofit projects replacing legacy loggers with standards-based Modbus polling
Knowledge base articles about SunSpec
SunSpec Modbus: one register map for many inverters
SunSpec Modbus is the open register map SMA, Fronius, SolarEdge and Kostal share. The layout, int+SF vs float, the TCP port per brand and reading a mixed fleet.
Fronius Modbus: read a Symo GEN24 over Modbus TCP
Fronius Modbus explained: enable Modbus TCP on the Symo GEN24 on port 502, choose between int+SF and float, read the right SunSpec registers and scale them correctly. Practical guide for solar installers.
SMA Modbus: reading a Sunny Boy over Modbus TCP (installers)
SMA Modbus explained: enable the Modbus TCP server on port 502, choose between the SMA profile (unit ID 3) and SunSpec (unit ID 126), read the right registers, and handle the NaN values at night. Practical guide for installers.
