The Solis S5-GR1P8K is an 8kW single-phase grid-tied inverter from the S5 series, designed for residential solar PV systems. It is not a hybrid inverter and does not have battery communication ports for direct energy storage integration.
The Dyness Powerbox Pro is a 10.24kWh low-voltage battery designed for residential energy storage systems.
⚠️ Important Compatibility Note: The S5-GR1P8K is a grid-tied inverter, NOT a hybrid inverter. It cannot directly connect to or manage a battery. To use the Powerbox Pro battery for energy storage, you need a hybrid inverter (e.g., Solis S6-EH1P series). These two products are not directly compatible as a combined storage system.
