The KEWO PV1000 132KW 250A is a colossal, utility-scale industrial solar pump inverter (Variable Frequency Drive). It is engineered for national infrastructure layouts, deep-well community water networks, and massive center-pivot agricultural developments requiring up to 180 Horsepower (180 HP).

Technical Specifications

• Power Output: 132 Kilowatts (132KW) / 180 HP.
• Current Output: 250 Amperes (250A) continuous rating, offering immense startup current and steady torque for high-volume inductive motors under intense hydraulic backpressure.
• Input Voltage (DC/PV): Wide operational envelope from 250V to 800V DC. The ideal continuous running MPPT voltage under heavy load is 540V to 750V DC.
• Output Voltage (AC): Standard industrial 3-Phase 380V / 400V / 415V AC.

Solar Array Configuration Guide

Sustaining a 180 HP motor demands an extensive solar field covering a massive footprint to generate a stable DC supply that satisfies the 250A requirement:

1. Total Solar Array Capacity: It is highly recommended to oversize the PV array to between 171 kW and 185 kW (1.3 to 1.4 times the drive capacity) to counteract midday heat degradation and cable 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 312 to 336 panels in total.
   • Correct Layout: Divide them into 14 parallel strings (14 Strings × 22 to 24 panels in series). This massive parallel combination multiplies incoming current input 14 times to safely meet the 250A demand while capping string voltages within the safe 800V DC upper limit.
