It contains information to help you plan wire routes, AC and DC connections, and find a suitable location for installation. It also discusses requirements for grounding the Sun Tie XR and your PV array. This chapter then provides procedures to install the Sun Tie XR, including mounting, making DC and AC connections, and grounding the inverter and the PV array.
Installation Installation Planning Overview Before you begin to install the Sun Tie XR you need to consider the following: • tools required • hardware and materials required • mounting location • routes for AC and DC wiring • AC and DC connection wire size requirements • grounding requirements • PV array requirements Tools required ❐ ❐ ❐ ❐ ❐ ❐ ❐ Phillips screwdrivers slot-head screwdrivers open-end wrenches socket wrench and fittings 3/32" hex bit multimeter frequency counter (optional) ❐ ❐ ❐ ❐ ❐ ❐ lev
Installation Planning Locating the Sun Tie XR The Sun Tie XR should be installed in locations that meet the following requirements: Vertical The UL listing for the Sun Tie XR requires it to be mounted vertically. Dry When the Sun Tie is mounted outdoors, attach the optional Rain Shield (STRS) to prevent water entering the unit. Temperature The unit meets specifications from 32 to 113 °F (0 to 45 °C) but will operate within the temperature extremes of most climates—from -38 to 113 °F (-39 to 45 °C).
Installation All wiring and installation methods should conform to applicable electrical and building codes. Pre-plan the wire and conduit runs. Knockouts for conduit holes are located on the bottom of the unit. See Figure 2-9. The DC terminal blocks in the Sun Tie XR accept up to a #6 AWG wire. The AC circuit disconnects accept cable sizes up to #6 AWG. For maximum safety, run AC and DC wires/cables in separate conduits.
Installation Planning AC circuit breaker requirements The main service panel must dedicate a 15 amp minimum, double pole breaker (120/240 volts AC) to operate the Sun Tie XR. Planning DC Connections DC connections include all the wires and connectors between your PV array and the Sun Tie XR’s combiner board. Figure 2-1 and Figure 2-2 show the combiner board and connection points. Figure 2-14 and Figure 2-15 show simplified diagrams of the entire installation.

Installation Planning DC grounding The negative PV conductor must be bonded to the grounding system at only one point in the system. See Figure 2-3 for the location of the Sun Tie XR ground bar. The size for the conductor is usually based on the size of the largest conductor in the DC system. Negative/ground bonding is accomplished by factory-wired PVGFP breakers.
Installation Note: The MPPT algorithm does not work with wind power or batteries. CAUTION Although the nominal voltage range suggests that you can use strings of five modules in series, this is not safe for the unit, as the PV array may exceed the inverter’s maximum input (120 VDC). WARNING: SHOCK HAZARD Whenever a PV array is exposed to sunlight, a shock hazard exists at the output cables or exposed terminals.
Installation Installation Overview Installation steps There are four main steps in the installation of the Sun Tie XR: 1. Mounting the unit 2. Making the DC connections from the PV array to the Sun Tie XR 3. Making the AC connections from the service utility panel to the Sun Tie XR 4. Grounding the PV array This section also discusses two installation options: connecting inverters in parallel and connecting the Remote Monitor.
Installation To mount the Sun Tie XR: 1. Locate the area where the Sun Tie XR is to be installed. Installing it as close to the utility service panel as possible is recommended.

Installation Connecting DC Wiring Fuse requirements Combiner board location Wiring procedure The combiner board in the Sun Tie XR accepts up to six individual PV array circuits (positive and negative wires). Each circuit on the combiner board contains a fuse to protect against over-current. Always replace this fuse with one of the same type and rating (GBB, 20 amp maximum, ceramic type, 0.25" x 1.25"). The combiner board is rated for 100 amps maximum input.
Installation 4. Connect the negative (–) wire from the PV array to the PV MINUS 1 (leftmost) terminal. Check that the wire is in the proper location and tighten the screw. 5. Repeat this procedure for each PV array circuit, connecting the #2 PV positive wire to the terminal labeled PV PLUS 2, and so on. The PV arrays do not have to connect in the order marked on the board (this is just for reference). All PV array positives on the combiner board are joined together AFTER the fuse. 6.
Installation WARNING: SHOCK HAZARD Before wiring the Sun Tie XR, ensure the main 120/240 volt breaker in the main utility breaker box is switched off. Switch this breaker on only after all wiring is completed as instructed in the procedures. To wire the main utility panel to the Sun Tie XR: 1. Run conduit from the main utility breaker panel to the lower section of the Sun Tie XR. Run the two HOT wires (L1 and L2) and ground through the conduit and into the Sun Tie XR’s lower section.

Startup Procedure Replace screws in the circuit breakers replace breaker cover grounding screw Figure 3-5 Circuit breaker cover and screws Replace screws (one on each side) Lock hole Figure 3-6 Outer cover and screws 975-0053-01-01 3–9
Operation Replace screws (two on each side) Rain Shield Figure 3-7 Rain Shield and screws Factors Affecting Sun Tie XR Performance This section describes several factors that will affect the amount of power that a properly installed and operating Sun Tie XR can produce.
Factors Affecting Sun Tie XR Performance Temperature and reduced output PV array temperature affects the output of the entire system. As the temperature on the array surface heats up, its energy output goes down. Roof-mounted arrays also collect the heat generated by the roof surface (or trapped under the array) and will produce less output than polemounted arrays, which allow greater air circulation behind the panels.
