SI23-D5 VEICHI Solar Pump Inverter:
Maximum Power Point Tracking function:
Built-in with the MPPT (maximum power point tracking) function, so the photovoltaic pumping system can produce better power outputs to improve the working efficiency of pumps.
Ingenuity brings brilliant control algorithm:
- Drive a variety of loads: supports PMSM, AM, electric spindle, AC pump, etc.
- Motor self-tune: international leading self-tune algorithm with high accuracy and consistency.
- High-speed low-magnetic control: high-bandwidth current vector and 12 times low-magnetic high-precision output.
Reliable performance and comprehensive and timely protection.
Solar pump protection functions:
Dry protection, low frequency protection, minimum power protection, sleep protection, overwater protection, pump overcurrent protection, etc.
Basic protection functions:
Overvoltage, undervoltage, inverter overcurrent, module fault, inverter overload, motor overload, current detection zero-drift fault, current detection fault, E2RCM fault, grounding short-circuit fault, input phase loss, output phase loss , inverter overheating, communication fault, motor parameter self-learning fault, etc.
Line-to-ground short-circuit detection: achieve full protections from the solar pump inverter to the motor.
