❓ Frequently Asked Questions (FAQ)
Q
What is the MPPT algorithm used in this solar pump inverter and what are its advantages?
This inverter uses the VI Maximum Power Point Tracking (MPPT) algorithm, which offers fast response speed and stable operation. Unlike traditional MPPT methods, it effectively solves poor tracking performance, unstable running, and potential water hammer damage caused by rapid changes in sunlight intensity.
Q
Does the solar pump inverter require batteries for energy storage?
No. This system is designed based on an eco-friendly and economical concept — it uses water storage instead of battery storage. There is no battery device required, and the pump is driven directly, which greatly reduces construction and maintenance costs while improving overall system reliability.
Q
What protection functions does the solar pump inverter provide?
The inverter offers comprehensive protection including: PV input under-voltage and over-voltage protection, input reverse polarity protection, DC over-current protection, output overload protection, short circuit protection, dry well protection, overflow protection, dry running protection, and blocking protection — ensuring safe and reliable operation under all conditions.
Q
What is the available power range for the solar pump inverter models?
The solar pump inverter series covers a wide power range from 1500W (SPI-1500W) up to 150KW (SPI-150KW), making it suitable for small domestic water supply systems as well as large-scale agricultural irrigation and industrial water pumping applications.
Q
Can the solar pump inverter be monitored remotely?
Yes. The inverter is optionally equipped with an RS485 data communication interface, which enables remote monitoring and data management. This feature supports integration with SCADA systems or other monitoring platforms for convenient real-time oversight.
Q
What is the difference between IP65 and IP20 protection ratings in the product lineup?
Models from SPI-1500W to SPI-30KW are rated IP65, meaning they are fully dust-tight and protected against water jets — suitable for outdoor installation environments. Models from SPI-37KW to SPI-150KW carry an IP20 rating, which provides protection against solid objects over 12mm but is intended for installation in protected indoor or enclosure environments.
