The KEWO PV1000 75KW 150A is a colossal, ultra-high-capacity industrial solar pump inverter (Variable Frequency Drive). It is engineered to command massive water motors, regional lifting stations, and high-yield large-borehole aquifers requiring up to 100 Horsepower (100 HP).

Technical Specifications

• Power Output: 75 Kilowatts (75KW) / 100 HP.
• Current Output: 150 Amperes (150A) continuous rating, engineered to generate massive starting torque to spin up exceptionally heavy hydraulic machinery under immediate backpressure.
• Input Voltage (DC/PV): Operates within a wide envelope of 250V to 800V DC. The ideal continuous running MPPT voltage under heavy load is 540V to 720V DC.
• Output Voltage (AC): Heavy industrial 3-Phase 380V / 400V / 415V AC.

Solar Array Configuration Guide

Sustaining a 100 HP motor demands an extensive, multi-string solar field setup to deliver a robust DC supply that satisfies the 150A requirement:

1. Total Solar Array Capacity: It is recommended to size the total PV field between 97.5 kW and 105 kW (1.3 to 1.4 times the drive capacity) to account for morning ramp-up, afternoon heat degradation, and line resistance losses.
2. String Wiring Layout: If utilizing modern 550W panels (with an Open Circuit Voltage \(V_{oc}\) of roughly 50V per panel):
   • You will need 176 to 190 panels in total.
   • Correct Layout: Divide them into eight parallel strings (8 Strings × 22 to 23 panels in series). This multi-parallel combination scales up your current input eight-fold to confidently meet the 150A requirement while capping string voltages safely beneath the 800V DC upper limit.
