The Aspire NERO is a dedicated 11kW solar water pump inverter driver with an integrated MPPT controller. It runs a three-phase pump motor directly from solar panels without any battery storage, and is built for irrigation, boreholes, farms and remote sites where dependable daylight-hours pumping matters. An auxiliary AC input lets you bring in grid or generator power when solar irradiation isn't enough on its own.

Key features of this 3 phase solar inverter

• Battery-free operation, runs directly from solar panels, no battery storage required
• Integrated MPPT, continuously tracks the maximum available solar power
• Motor output, three-phase, for water pumps and irrigation systems
• Max DC input voltage, 800V
• Max PV array power, 17,600W
• Soft start, reduces water hammer and mechanical stress on the pump
• Monitoring, RS485 port for remote monitoring, with LCD and LED indicators showing real-time data
• Auxiliary AC input, accepts grid or generator supply when sunlight is limited

How it works

The integrated MPPT pulls the maximum available power from the PV array at whatever irradiance level is present, feeding it straight to the three-phase motor drive. It can start pumping from a fraction of full solar power, so it keeps working in early morning and late afternoon light when a simpler on/off system would sit idle. If irradiation drops too low to sustain the pump, the auxiliary AC input takes over from a grid connection or diesel generator. Soft start ramps the motor speed up gradually, easing mechanical shock on the pump and pipework.

Applications

• Agricultural irrigation and livestock watering
• Borehole and groundwater extraction on farms and remote sites
• Industrial and municipal water supply pumping
• Three-phase pump installations where mains power is unavailable or costly

Installation notes

This unit drives three-phase pump motors and is not a home energy storage or battery inverter. The PV string voltage needs to stay within the inverter's operating window across the expected temperature and irradiance range on site. Professional installation is required for wiring, protection and commissioning, and it must not be connected to a battery bank.
