Strong Energy Alfred 10 (battery)
Strong Energy
Overview
The Strong Energy Alfred 10 is an all-in-one residential and commercial battery storage system combining a 10 kW hybrid inverter with a lithium iron phosphate battery in capacities from 12 kWh to 24 kWh. This ModbusCloud template communicates over Modbus TCP and reads battery state of charge (register 8192), instantaneous power (register 8201), and cumulative energy throughput (register 8209). Five write registers (8448 to 8451, 8524) expose the battery operating mode, enabling charge and discharge control from your portal. Together these registers give installers and asset managers a complete picture of storage behaviour and direct control over operating modes without accessing the Alfred 10 locally.
Use cases
- Monitor battery state of charge continuously to detect abnormal self-discharge between charge cycles.
- Track cumulative energy throughput over time to assess battery ageing and plan preventive maintenance.
- Alert on sudden power sign reversals to catch unexpected discharge events during low-tariff periods.
- Verify that battery mode setpoints written via the portal are correctly accepted by the Alfred 10.
- Report daily charge and discharge cycles to building owners as part of a monthly energy performance summary.
