Overview
Reviews

The KEWO PV1000 18.5KW 38A is a heavy-duty industrial-grade solar pump inverter (Variable Frequency Drive). It is designed to run large-scale water pumps or pivot irrigation systems rated up to 25 Horsepower (25 HP).

Technical Specifications

Power Output: 18.5 Kilowatts (18.5KW) / 25 HP.
Current Output: 38 Amperes (38A) continuous rating, engineered to handle heavy starting currents and prevent overloading trips.
Input Voltage (DC/PV): Accepts 250V to 800V DC. The ideal running MPPT voltage under load is between 540V and 700V DC.
Output Voltage (AC): Standard industrial 3-Phase 380V / 400V / 415V AC.

Solar Array Configuration Guide

A 25 HP load requires a robust solar array layout to ensure continuous water flow even on hazy or partially cloudy days:

Total Solar Array Capacity: It is recommended to size your PV array between 24 kW and 26 kW (roughly 1.3 to 1.4 times the drive capacity).
String Wiring Layout: If you use standard 550W panels (with an Open Circuit Voltage \(V_{oc}\) of roughly 50V per panel):
- You will need 44 to 48 panels in total.
- Correct Layout: Divide them into two parallel strings (2 Strings × 22 or 24 panels in series). This ensures that the voltage safely stays beneath the 800V limit while maximizing total current for heavy lifting.
