Frequently Asked Questions
Frequently Asked Questions
Q
What is MPPT technology and why is it important for solar water pumping systems?
What is MPPT technology and why is it important for solar water pumping systems?
MPPT (Maximum Power Point Tracking) is a self-developed technology that continuously optimises the power drawn from photovoltaic panels. It maximises energy extraction under varying light conditions, ensuring the pump operates normally even on cloudy days or in low-light environments, significantly improving overall system efficiency.
Q
Does the solar pump inverter require batteries to operate?
Does the solar pump inverter require batteries to operate?
No. The system is designed to operate without batteries. It draws power directly from solar panels via the DC input, which reduces system complexity, lowers maintenance costs, and simplifies the overall installation.
Q
What protection features does the inverter provide for the pump?
What protection features does the inverter provide for the pump?
The inverter includes comprehensive protection functions such as anti-dry burning, over-current, under-voltage, short-circuit, and motor blocking protections. These safeguards ensure the long-term safe operation of both the pump and the inverter under various conditions.
Q
What power range is available and which types of pumps are compatible?
What power range is available and which types of pumps are compatible?
The inverter is available in models ranging from 1.5KW to 22KW. It is compatible with all standard three-phase AC water pumps, making it suitable for a wide range of agricultural, industrial, and residential water pumping applications.
