Overview
Reviews

The KEWO PV1000 37KW 75A is a high-capacity, heavy-duty industrial solar pump inverter (Variable Frequency Drive). It is built to power massive industrial water pumps and large-scale center-pivot irrigation networks rated up to 50 Horsepower (50 HP).

Technical Specifications

Power Output: 37 Kilowatts (37KW) / 50 HP.
Current Output: 75 Amperes (75A) continuous rating, delivering the immense startup torque needed to lift high volumes of water from deep underground boreholes.
Input Voltage (DC/PV): Wide operational window from 250V to 800V DC. The ideal continuous running MPPT voltage under heavy load is 540V to 720V DC.
Output Voltage (AC): Standard industrial 3-Phase 380V / 400V / 415V AC.

Solar Array Configuration Guide

Sustaining a 50 HP motor requires a massive solar footprint. Sizing the PV array properly prevents system dropouts during low-light hours or extreme summer heat:

Total Solar Array Capacity: It is highly recommended to oversize the PV array to between 48 kW and 52 kW (1.3 to 1.4 times the inverter rating).
String Wiring Layout: If utilizing standard 550W panels (with an Open Circuit Voltage \(V_{oc}\) of roughly 50V per panel):
- You will need 88 to 96 panels in total.
- Correct Layout: Divide them into four parallel strings (4 Strings × 22 or 24 panels in series). This configuration multiplies the incoming current four times to meet the heavy amp requirement while keeping the series string voltage safely within the 800V DC ceiling.
