Data Generated by the System

SOLARWATT Inverters, Batteries and Chargers generates data related to their performance, usage, and environment.

a) Type and Nature of Data:

The system is capable of generating the following categories of data:

• Energy Data like solar energy production (kW, kWh), battery charge/discharge levels (kWh, %), state of charge (%), home energy consumption from grid/solar/battery (kW, kWh)... for a recent list, see following tables.
• Performance Data like battery cell temperature (°C), system uptime, voltage and current readings... for a recent list, see following tables.
• Operational Data like system status (e.g., charging, discharging, standby), operational mode settings (e.g., self-consumption, time-of-use), and event logs (e.g., grid outages)... for a recent list, see following tables.
• Diagnostic Data like error codes and system fault reports... for a recent list, see following tables.

a.1) EMS and Monitoring Cloud Data

Cloud data which has no direct local representation is generated using other data. For example: The Production Date (dateOfProduction) is derived from the device's serial number.
