About FRN0011C2S-4SL1 Fuji Mini Solar 3.7KW 5HP 440V

The

FRN0011C2S-4SL1

is a specialized version of the FRENIC-Mini (C2) series, specifically designed as a Solar Water Pump Controller. Unlike standard industrial VFDs, it is optimized to run 3.7 kW (5 HP) water pumps using power directly from solar photovoltaic (PV) panels.

Fuji Electrics new compact inverter FRENIC-Mini (C2) Series provides excellent performance for both single-phase and three-phase applications and is available in multiple configurations to support 1/8 HP up to 20 HP AC drives / variable frequency drives (VFD) / v/ Hz vector drives. With an expanded range of rated voltages, the new FRENIC-Mini (C2) strikes an optimal balance between price and performance.

Weight: ~5.5 lbs (2.5 kg).
Power Rating: 3.7 kW / 5 HP.
Input Voltage: Designed for a high DC input voltage (typically up to 800 VDC for solar) or 3-phase 380V480V AC.
Output Current: 9.0A to 10.5A.

Core "Solar Drive" Functions

MPPT (Maximum Power Point Tracking): This is the drive's most critical function. It automatically adjusts the pump speed based on available sunlight to extract the maximum possible power from the solar panels.
Dry Run Protection: Detects if the water source has run dry, stopping the pump to prevent damage to the motor and seals.
Automatic Start/Stop: Operates autonomously based on solar intensitystarting the pump at sunrise and stopping it at sunset without manual intervention.
Dynamic Torque Vector Control: Provides high starting torque (150% at 1 Hz) to help the pump overcome initial resistance, which is especially useful in deep-well applications.

The FRN0011C2S-4SL1 is a specialized Solar Pump Inverter from the FRENIC-Mini series. Its primary function is to convert DC power from solar panels into 3-phase AC power to run a water pump efficiently without needing a battery or grid power.

Core Solar Functions

Maximum Power Point Tracking (MPPT): This is its most important feature. It continuously tracks the sunlight intensity and adjusts the motor speed to ensure the pump always extracts the maximum available power from the solar PV panels.
Automatic Start/Stop: The drive operates autonomously. It wakes up and starts the pump when it detects enough sunlight in the morning and safely shuts down when the sun sets or if clouds block the light.
Dry Run Protection: It monitors the motor's load. If the well or tank runs out of water, the drive detects the drop in torque and stops the pump to prevent the motor from overheating or burning out.
Wide DC Input Range: Specifically built to handle the high-voltage DC (up to 800V DC) typically generated by solar arrays, while also being capable of accepting standard 3-phase AC power if available.

Pump & Motor Management

Dynamic Torque Vector Control: Provides a high starting torque (150% at 1 Hz). This is crucial for deep-well pumps that need a strong "push" to overcome water head pressure and friction when they first start spinning.
Tank Level Control: Can be connected to float switches or sensors to automatically stop pumping once a storage tank is full and restart when the level drops.
Over-voltage & Surge Protection: Includes built-in protection against the voltage spikes that can occur in DC solar systems during rapid weather changes.
