3. Planning

3.1 General Requirements

Installation of this equipment should only be performed by qualied technicians.

Installers must meet all local and state code requirements for licensing and training for

the installation of Electrical Power Systems with AC and DC voltages to 600 volts.

The inverter must be anchored to a concrete pad. The mounting pad must meet local

seismic requirements. See

Appendix C - Mechanical Drawings

for concrete pad

mounting specications.

Planning

Planning for a system requires complete understanding of the processes involved to

successfully install the inverters and meet all required local, state and national codes.

3.2 Handling

Inverters weigh up to 5,200 pounds with their pallet and packaging. If the inverter is

improperly handled serious damage can occur and the warranty may be voided. Only

use lifting equipment, a forklift or pallet jack, that is rated for the weight of the inverter.

Only use the specied lifting points. Leave the inverter on its shipping pallet with the

protective plastic wrap in place until it is time to install.

3.3 Location and Clearances

Location

Select a suitable location to install the inverter. The inverter must be installed on a at,

solid surface, such as a concrete pad. The inverter should be located as close to the array

as possible to minimize the DC wire length.

Inverters are capable of emitting high frequency switching noise and should be located

away from noise sensitive areas that are populated by people or animals.

Clearances

Left and Right Sides – PV Powered recommends providing a minimum of 12 inches of

clearance on one side of the inverter and 36 inches on the other side (working clearances

must also comply with NEC 110.26 or applicable Canadian Electrical Code) to allow

access to the external mounting anges. The installer may select which side has a 36

inch clearance. The 36 inches will provide future access to the magnetics section for

retorquing bolts and thermal scans of connections. However, the 36 inches on the side

is not a NEC setback requirement. 12 inches on each side is an acceptable installation

practice.

Rear – A rear clearance of two (2) inches is required behind the inverter to allow room

for full opening of the air intake hood.
