Description
BR500-P Solar Pump Inverter Overview
The ZK500-P series powers three-phase or single-phase AC pumps using solar DC input. Built on the reliable ZK500 VFD platform, it features MPPT, rapid speed adjustment in low sunlight, and flexible pump compatibility—supporting both DC/AC input and 1/3-phase output.
Ideal for water-scarce regions, it enables sustainable household water supply, irrigation, and agriculture, replacing diesel generators with clean energy. hygienic standard, no-dead corner, easy to clean, easy operation & maintenance.
Features BR500-P Solar Pump Inverter
-
Efficient intelligent control to improve energy utilization
– The MPPT efficiency is as high as 99.8%, and the power factor of inverters below 15KW is not less than 0.96, maximizing solar energy conversion and reducing energy consumption costs.
– Automatically adapt to PMSM/synchronous motors, no manual parameter adjustment required, saving time and effort.
-
Multiple safety protections, stable and durable
– Dry-running, over-current, phase loss, minimum power input and other protections extend the life of pumps and equipment.
– Independent air duct design + triple-proof paint + enhanced lightning protection, adapting to harsh environments such as humidity and dust.
-
Flexible compatibility, remote intelligent management
– Dual-mode power supply, supporting AC/DC dual power input to cope with complex power usage scenarios.
– Remote monitoring, real-time parameter adjustment, fault alarm, and reduced operation and maintenance costs.
-
High-precision performance optimization
– PQ flow curve calculation accurately matches the pump flow demand to avoid energy waste.
– Imported IGBT modules (Infineon/Fuji) ensure long-term stable operation.
