Overview
Reviews

The KEWO PV1000 45KW 90A is one of the largest models in this product family, classified as a super heavy-duty industrial solar pump inverter (Variable Frequency Drive). It is purpose-built to operate massive water motors, central water stations, and ultra-deep boreholes requiring up to 60 Horsepower (60 HP).

Technical Specifications

Power Output: 45 Kilowatts (45KW) / 60 HP.
Current Output: 90 Amperes (90A) continuous rating, delivering extraordinary starting torque to lift heavy hydraulic loads under high-head conditions.
Input Voltage (DC/PV): Wide working range from 250V to 800V DC. The ideal continuous running MPPT voltage under full load is 540V to 720V DC.
Output Voltage (AC): Heavy industrial 3-Phase 380V / 400V / 415V AC.

Solar Array Configuration Guide

Sustaining a 60 HP motor requires an expansive, carefully engineered solar field to deliver a stable DC supply that can generate 90A AC without cutting out:

Total Solar Array Capacity: It is highly recommended to size the total PV field between 58 kW and 63 kW (1.3 to 1.4 times the drive capacity) to account for cloud tracking and high-temperature power drops.
String Wiring Layout: If utilizing modern 550W panels (with an Open Circuit Voltage \(V_{oc}\) of roughly 50V per panel):
- You will need 106 to 114 panels in total.
- Correct Layout: Divide them into five parallel strings (5 Strings × 21 or 22 panels in series). This parallel combination multiplies your current input 5 times to safely meet the 90A threshold while keeping string voltages beneath the 800V DC upper limit.
