The Aspire 7.5kW is a solar pump inverter built for three-phase asynchronous induction motors up to 10HP. It runs straight from a PV array with no battery needed, using an integrated MPPT covering a 250-780V DC input range and a maximum PV input of 9,500W. RS485 monitoring, a display screen, and a full protection suite are built in.

Key features of this solar pump inverter

• Battery-free operation, draws power directly from solar panels
• MPPT input range, 250V to 780V DC
• Max PV input power, 9,500W
• Motor compatibility, three-phase asynchronous induction motors up to 10HP (7.5kW)
• Automatic start/stop, responds to solar irradiation levels without manual input
• Soft start, reduces water hammer and inrush current at start-up

Product overview

A DSP-based closed-loop control drives the motor smoothly as irradiance changes through the day. The MPPT tracks the array's maximum power point continuously, so pump output adjusts with available sunlight rather than dropping out. Soft start limits mechanical shock on the pipework and motor at start-up, and the unit runs its own self-diagnostics alongside LED status indicators and an onboard display.

Applications

Suited to agricultural irrigation, livestock watering, borehole and groundwater extraction, and rural water supply or sanitation projects. It fits any three-phase pump application where mains power is unavailable or not practical to install.

Installation notes

This is a pump inverter for three-phase motors, not a battery or home energy storage inverter. The PV string voltage must stay within the 250-780V MPPT window under all operating conditions, and installation should be carried out by a qualified professional. Do not connect it to a battery bank.
