Keysight N8937APV Photovoltaic Array Simulator

Overview

The Keysight N8937APV Photovoltaic Array Simulator is a 15 kW programmable DC power source designed to simulate the output characteristics of real-world photovoltaic arrays. It enables comprehensive testing and validation of solar inverter maximum power point tracking (MPPT) algorithms under controlled environmental conditions.

Instead of relying on expensive and time-consuming under-the-sun testing, the N8937APV allows developers to quickly simulate complex I-V curve characteristics by adjusting temperature, irradiance, cell technology, age, and other environmental parameters. This facilitates accelerated algorithm development and manufacturing line validation for solar inverter systems.
