The OWP-BL43-440T electric coolant pump integrates a closed impeller design, achieving high operational efficiency while restricting noise to ≤60dB, perfect for the quiet operation demands of solar energy installations. Built with permanent magnet brushless technology, it offers a compact size and low power consumption, optimizing space usage and energy savings in PV inverter systems. The pump’s shaft assembly employs ultra-long-life friction pair materials, combined with a centrifugal & shielded structure, ensuring a service life exceeding 20000 hours for consistent long-term performance. PWM duty cycle speed regulation provides precise flow control, allowing seamless adaptation to the dynamic heat generation of PV inverters. It is equipped with comprehensive protection features, including reverse connection protection, overvoltage protection, overcurrent protection, dry running protection, and overtemperature protection, effectively safeguarding the pump and the entire liquid cooling system from potential malfunctions. With an IP68 rating, the pump delivers exceptional waterproof and dustproof capabilities, thriving in the harsh outdoor conditions typical of solar farms.
The OWP-BL43-440T electric coolant pump is specially designed to meet the critical liquid cooling needs of PV inverters in the solar energy industry. PV inverters are essential components that convert direct current (DC) generated by solar panels into alternating current (AC) for practical use, and they produce significant heat during high-power conversion processes—excessive heat can reduce inverter efficiency, accelerate component aging, and lead to unexpected downtime, directly affecting the overall energy output of solar systems. This 400W rated coolant pump delivers a rated flow rate of 3000L/H at 20M head and a maximum flow rate of 5000L/H with a 23M max lift, ensuring robust coolant circulation to efficiently dissipate heat from power modules, capacitors, and other heat-generating components in PV inverters. Its compatibility with 50-60% glycol + water mixtures, dielectric oil, and electronic fluorinated solutions aligns with the cooling medium requirements of most PV inverter liquid cooling systems, enabling straightforward integration. The wide medium temperature range (-40℃ to 85℃) allows reliable operation in extreme outdoor environments, from frigid winters to scorching summers in solar farms. The 25mm outlet diameter ensures sufficient coolant delivery, while PWM speed regulation enables real-time flow adjustment to match the inverter’s heat output during varying solar irradiance conditions. The high/low-level fault feedback signal provides instant operational status monitoring, facilitating timely maintenance and minimizing solar energy production losses. With IP68 protection and robust safety features, the OWP-BL43-440T guarantees stable, durable performance, making it the ideal cooling solution to enhance the efficiency, reliability, and service life of PV inverters in the solar PV industry.
