- Maximum PV input power: 9,500W
- Supports three-phase asynchronous induction motors up to 10HP (7.5kW)
- Automatic start and stop based on solar irradiation level
- Soft start function reduces water hammer and extends pump and system life
- Built-in full protection suite and self-diagnostics
- LED indicators and display screen for real-time system status
- RS485 remote monitoring port
- Environmentally friendly design with low maintenance requirements
Product Overview
The Aspire 7.5kW solar pump inverter uses closed-loop control with a DSP processor to drive three-phase asynchronous induction motors smoothly and efficiently directly from solar power. The built-in MPPT continuously tracks the maximum power point of the PV array, optimising pump performance throughout the day as irradiance changes.
The inverter starts and stops automatically based on available solar power, removing the need for manual intervention. Soft start limits the inrush current and mechanical shock at start-up, protecting both the motor and the pipework from the stress of sudden full-speed starts.

Installation and Safety Notes
This is a solar pump inverter driver for three-phase motors, not a home energy storage or battery inverter. PV string voltage must be designed to stay within the 250-780V MPPT window under all operating conditions. Professional installation is required for correct wiring, protection, and commissioning. Do not connect to a battery bank.
