For the USA: National Electrical Code, ANSI NFPA 70
For Canada: Canadian Electrical Code, Part 1
• For UL 1741 compliant Installations:
The system shall not be aggregated above 30kW on a point of common
connection.
The inverters must always be installed on a branch circuit with a 2P + 1P
external transient voltage surge arrestor. The external device must meet
IEC 61643-1 class II requirements.
• For AS 4777 compliant installations:
The inverters must always be installed on a branch circuit with a 2P + 1P
external transient voltage surge arrestor. The external device must meet
IEC 61643-1 class II requirements.
• All Canadian installations must comply and be in accordance with the Canadian
Electrical Code, Part 1. Input and output circuits of the inverters must be isolated
from the enclosure.
• For VDE 4105 compliance, installations are limited in size to 3.68kVA.
• In jurisdictions that require it, a location-specific disconnect (such as an ENS box)
must be part of the installation.
• For compliance with NEC code, please note:
1.6 Installation safety instructions
• The Enecsys micro inverters are provided with fixed trip limits for both voltage and
frequency.
• The External Earth connection screw shall be torqued to 6Nm +/- 10%.
• The system grounding is the responsibility of the installer.
WARNING:
Whenever the PV module is exposed to light, it supplies a DC voltage. Follow
all safety instructions and warnings provided by the module manufacturer’s
documentation.
WARNING: Power fed from more than one source.
WARNING: The micro inverters, gateway and repeaters contain no user
serviceable parts and must be returned to the supplier in the case of
damage. Micro inverters with damage to integrated power supply cords
should not be installed or serviced: they must be returned to the supplier.
WARNING:
The Enecsys micro inverter, gateway, and monitoring components work in
conjunction to report faults. For NEC compliance, do not install the PV
system without the micro inverter, gateway, and monitoring components in
place.
