Description
Product Overview
The multi-function power meter is designed to meet the power monitoring requirements of power systems, industrial and mining enterprises, public utilities, and intelligent buildings. It can measure all common electrical parameters with high precision, such as three-phase voltage, three-phase current, active power, reactive power, frequency, power factor, and four-quadrant electric energy. It adopts high-visibility LEDs to display the parameters measured by the meter and the operation information of the power grid system. The meter panel is equipped with four programming keys, allowing users to conveniently switch displays and program meter parameters on-site, which delivers strong flexibility.
1. Three phase AC solar pump off-grid inverter is designed to converter DC (direct current) from Solar panel into AC (alternative current) to drive the pump.
2. Inbuild MPPT + VFD (Variable Frequency Drive) to improve AC pump’s efficiency and protect AC pump
3. Large HMI graphic display interface for monitoring, setting . 4 keys for easy operation
4. Dry running protection and self-restart function
5. Waterproof and dustproof level up to IP65
6. Reliable for terrible environment, operate temperature -20°C ~ +60°C
