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.
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.
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.
