Refer to the span tables in “Appendix A: Span Tables” on page 57 to determine the recommended measurements as they pertain to your location. Snow Loading To determine the ground snow load at the installation site, consult with your local building and safety department for the specific requirements for your location. AC Modules should not be installed in snowdrift areas of the roof. Basic Wind Speed Determine the wind speed at your installation site and consult your local building and safety department for guidelines. Roof Zones Locate the area on the roof where you will be installing the solar array. The roof is divided into three zones: the interior, edges, and corners. Interior The innermost area surrounded by the edges, also referred to as the field. Edges The edges are defined as 10% of the least horizontal dimension or a minimum of 3′ (0.9 m) from the edge of the roof and represent areas of higher wind load. Corners The corners are defined as the intersection of two edge zones on the leading edge of the roof. Wind loads are highest in the corner zones and lowest in the interior zone. AC Modules should not be mounted in the corner...

sunMAX Lesson 7.9 – Solar Gateway Provisioning

Lesson 7 – Execute the Installation 7.9 – Solar Gateway Provisioning Solar Gateway Hardware The purpose of the Solar Gateway is to communicate with and gather data from all Microinverters in the solar array and forward information to Ubiquiti’s sunMAX Cloud Management system via the customer home network. LEDs The hardware LEDs provide insight into solar operation. The Power LED will light steady green when the device is connected to a power source. The LED may flash during general system activity. The Network Activity LED will light steady green when the network and cloud are connected. It will light red if a network connection cannot be established. The Inverter Activity LED will light steady green if all Microinverters are detected. It will light yellow if one or more of the Microinverters are missing and light red if errors are detected on any of the Microinverters.   Connectors Because the Solar Gateway plugs a single Microinverter and Trunk cable, it features two external connectors: The Input connector runs from the Solar Gateway to a Microinverter. The Output connector runs from the AC trunk cable to the Solar Gateway.   To install the Solar gateway: Tilt the device forward and hook it underneath the upper edge of the solar module railing. Rotate the gateway down until it stops and rests along the side of the solar module. Use the AC Disconnect...

sunMAX Lesson 7.8 – Equipment & System Grounding

Lesson 7 – Execute the Installation 7.8 – Equipment & System Grounding WARNING: Wiring work should be performed according to the provisions of the National Electrical Code. Grounding work and wiring connections throughout the installation should be performed by a qualified electrician. Grounding & sunMAX Residential purpose The purpose of grounding is to provide a path for electrical current to return to earth, reducing the risk of damage to equipment or shock to humans under conditions known as a fault. To offset the high voltage potential difference during a fault, a conductive path leading back to a grounding rod placed 6 or more feet underground can help maintain potential balance between earth (0V) and the grounded path. types Equipment Grounding is a type of Grounding that calls for the electrical bonding of all non-current carrying components in the PV system, such as panel frames and connectors. Comparatively, System Grounding is the means by which a Current-carrying Conductor is grounded to earth by means of bonding to the Equipment Grounding system. The sunMAX mounting system provides a built-in integrated grounding system to bond the array together. When panel connectors are installed they provide up to a 4 way bond with adjacent modules and/or trim skirts. By bonding modules into one continuous system only a single wire equipment grounding conductor (EGC) is required for up to 16 contiguous modules. The grounding...
