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.

High efficiency with excellent debugging tool.

  •  Host computer debugging software: VCACSost Ver1.3 is easy to operate and configure parameters and provides customers with unprecedented flexibility.
  •  Firmware upgrade: built-in software directly upgrades online that greatly reduces maintenance and replacement costs.
