Frequently Asked Questions
Q
What is MPPT and why is it important for solar water pump inverters?
What is MPPT and why is it important for solar water pump inverters?
MPPT (Maximum Power Point Tracking) is a technology that continuously adjusts the electrical operating point of the solar panels to extract the maximum available power under varying light conditions. For solar water pump inverters, this means the pump can operate efficiently even on cloudy days or during low-light periods, significantly improving overall system performance and water output.
Q
Does the solar water pump inverter require batteries to operate?
Does the solar water pump inverter require batteries to operate?
No. The SPI series solar water pump inverter is designed to work without batteries. The system draws power directly from the photovoltaic panels, which reduces system complexity, lowers upfront costs, and minimises long-term maintenance requirements.
Q
What types of water pumps are compatible with this inverter?
What types of water pumps are compatible with this inverter?
The SPI series inverter is compatible with all standard three-phase AC water pumps. It supports motor output power ranging from 1.5KW up to 22KW, making it suitable for a wide range of agricultural irrigation, water supply, and industrial pumping applications.
Q
What protection features does the SPI solar pump inverter include?
What protection features does the SPI solar pump inverter include?
The inverter is equipped with comprehensive protection functions including anti-dry burning protection, over-current protection, under-voltage protection, short-circuit protection, and motor blocking protection. These safeguards ensure the long-term safe and reliable operation of both the pump and the inverter itself.
Q
Can the inverter be used in remote or high-altitude locations?
Can the inverter be used in remote or high-altitude locations?
Yes. The SPI inverter is rated for operation at altitudes up to 3000 metres without any derating. For installations above 3000m, derated operation is required. With an operating temperature range of -25℃ to +60℃, an IP65 protection rating, and natural cooling design, it is well-suited for remote, off-grid, and harsh outdoor environments.
Q
Is customisation available for special application requirements?
Is customisation available for special application requirements?
Yes. The SPI series can be customised to meet customers’ specific requirements, including special voltage ranges, communication protocols, enclosure configurations, or control logic. Please contact our technical team to discuss your application needs and we will provide a tailored solution.
