Overview

With a humidity tolerance of up to 95% RH and an adjustable output frequency (0~50/60Hz), this solar pump controller includes a built-in air-cooling system to ensure stable operation in temperatures ranging from -10°C to 40°C. The water pump inverter is particularly suited for applications such as drought relief in agriculture and seawater desalination, leveraging green technology to enhance water resource management.

Features

High-Efficiency MPPT Control: This pump inverter utilizes advanced MPPT technology to track the optimal operating point of solar panels in real-time, optimizing both voltage and current for system efficiency of up to 98%.
Smart Sleep Mode: Automatically adjusts its operation based on sunlight intensity. The water pump inverter enters sleep mode during low sunlight to save energy and quickly resumes operation when sunlight increases, maximizing solar resource utilization.
Water Level Adaptive Control: Integrated with water level sensing, the VFD solar inverter automatically stops when the water level is high to prevent overflow and restarts when the water level is low to avoid dry running, enabling unattended automated management.
Intelligent User Interface: The solar pumping inverter features an intuitive control panel with support for water level detection and smart control, ensuring user-friendly and safe operation while preventing equipment damage.
Fault Self-Protection: Built-in multiple protection mechanisms immediately activate self-protection in case of faults, ensuring stable system operation and enhancing overall system reliability.
AC Bypass Backup: Includes an integrated AC bypass function. During insufficient or no sunlight periods, the solar pump controller automatically switches to an AC power supply, ensuring uninterrupted water pumping.

FAQ

How to maintain and service a solar pump inverter?

As a key component of a solar power system, the performance and stability of the inverter directly impacts the system's efficiency and lifespan. Therefore, regular maintenance is crucial. Below are detailed instructions for maintaining and servicing the inverter:

Cleaning the Enclosure and Cooling Fan: Clean the inverter’s enclosure regularly (e.g., quarterly or semi-annually) using a soft, dry cloth or a slightly damp cloth. Avoid using corrosive cleaners. Check if the cooling fan is clogged with dust and clean it using a blower or vacuum if necessary to ensure proper operation and heat dissipation.
Checking Cable Connections: Inspect the cable connections between the solar pump inverter, solar panels, battery bank, and load for looseness or damage. Tighten any loose connections and replace damaged cables promptly to prevent short circuits or poor contact.
Monitoring the Display or Indicator Lights: Regularly check the inverter’s display or indicator lights to assess the operational status, including voltage, current, and power parameters. If abnormal readings or warning lights appear, shut down the system and troubleshoot before restarting.
Inspecting Internal Components: For experienced users or professionals, periodically open the inverter’s enclosure (after powering off) and inspect internal components such as capacitors, resistors, and transistors for signs of aging or damage. Replace any faulty components to maintain stable inverter performance.
Considering Environmental Conditions: Ensure the inverter is installed in a well-ventilated, dry, and non-corrosive environment, avoiding direct sunlight and rain exposure. If the installation environment is harsh, take corrective actions such as adding a sunshade or improving ventilation.
Keeping Maintenance Records: Maintain a record of all maintenance activities, noting the date, tasks performed, issues found, and corrective actions taken. Analyzing these records can help identify potential problems early and provide a basis for future maintenance.
