The KEWO PV1000 55KW 110A is a top-tier, ultra-high-capacity industrial solar pump inverter (Variable Frequency Drive). It is designed to command massive agricultural water motors, regional lifting stations, and ultra-deep large-borehole aquifers requiring up to 75 Horsepower (75 HP).

Technical Specifications

• Power Output: 55 Kilowatts (55KW) / 75 HP.
• Current Output: 110 Amperes (110A) 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 75 HP motor demands an extensive, multi-string solar field setup to deliver a robust DC supply that satisfies the 110A requirement:

1. Total Solar Array Capacity: It is recommended to size the total PV field between 71.5 kW and 77 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 130 to 140 panels in total.
   • Correct Layout: Divide them into six parallel strings (6 Strings × 21 to 23 panels in series). This multi-parallel combination scales up your current input six-fold to confidently meet the 110A requirement while capping string voltages safely beneath the 800V DC upper limit.
