Xantrex Technology PV100S-208 manual DC Interface Enclosure, Transformer Enclosure

Introduction

DC Interface Enclosure

The DC Interface Enclosure is NEMA-3R rated. The DC interface serves as the connection interface between the PV array and the PV100S. This enclosure is where the DC Disconnect Switch and DC contactor reside.

CAUTION: Equipment Damage

The fuses within the PV100S are intended for protecting the PV100S control circuitry only. They are not intended to provide protection for the PV array or external cabling.

Transformer Enclosure

The Transformer Enclosure is NEMA-3R rated. The main isolation transformer inside electrically isolates the PV100S from the utility power. Voltage-sensing circuit wiring and soft-start circuit pass through the Transformer Enclosure from the AC Interface Enclosure to the Main Inverter Enclosure.

AC Interface Enclosure

The AC Interface Enclosure is NEMA-3R rated. The AC interface serves as the connection between the utility and the isolation transformer. This enclosure is where the AC line fuses and AC disconnect switch reside. Also included in the AC Interface Enclosure are the main AC contactor and transformer soft-start circuit.
