PVI 1800/PVI 2500
Installation and Operation Manual

Multiple Units:
Multiple PVI 1800 or PVI 2500 units can be used at the same location/facility assuming all codes are
followed including NEC, local building codes and area utility guidelines. If multiple units are used, each
inverter should have its own dedicated circuit breaker, and a PV string must only be wired to one inverter
(although multiple PV strings can be used on each inverter up to unit ratings and power levels).
AC Circuit Breakers:
A dedicated AC circuit breaker in the home or building circuit panel is required for the PV inverter. For
both the PVI 1800 and PVI 2500, a 15 Amp, 208/240V AC rated 2–circuit breaker is required.
AC and DC Disconnects:
It is recommended that the PV system AC and DC disconnects be located beside the inverter if possible
but must conform to local code for your installation. This placement will make the best use of the “pre-
wired” inverter feature and save installation time, material and effort as well as making a simple, reliable
system. If local code requirements call for the AC and/or DC disconnect(s) to be mounted in another
location, you can consider relocating the inverter also to the required location or add a small junction box
or termination box to connect the PVI wires to building wiring going to disconnect location(s). Fig. 7
shows a typical installation with the AC and DC disconnects located on either side of the inverter.
