    MicroGT 500 inverter system and the PV array. • Be aware that the body of the MicroGT 500 inverter is the heat sink and can reach high temperatures. To reduce risk of burns, do not touch the body of the MicroGT 500.

  • Page 6: Introduction

    Introduction Introduction Congratulations on your purchase of a MicroGT 500 inverter. This microinverter is used in utility-interactive grid-tied applications, and the microinverter system is comprised of two key elements: • MicroGT 500 inverter • MagWeb GT unit* Figure 1 is an example of a basic system installation diagram using multiple MicroGT 500 microinverters (and the optional MagWeb GT).

    6.5” (16.5 cm) Figure 2, MicroGT 500 Dimensions A PV system using MicroGT 500 inverters is simple to install (Figure 3). Each MicroGT 500 easily mounts on the PV racking, directly beneath the PV module(s). Low voltage DC wires connect from the PV module directly to the MicroGT 500, eliminating the risk of high DC voltage.

    • Torque wrench Note: MicroGT 500 inverters are designed to only operate when they can sense power coming from the grid. Even if they are plugged into the PV array, they will not turn themselves on until they can read power from the grid.

  • Page 9: Step 1: Installing The Ac Junction Box

    Installation Step 1: Installing the AC Junction Box First, install and wire an AC branch circuit junction box (Figure 4). 1. Install an appropriate junction box at a suitable location on the PV racking system (typically at the end of a branch of modules). 2.

    Installation Step 2: Attaching the MicroGTs to the PV Frame/Rack 1. Mark the location of each MicroGT 500 inverter on the PV rack— keep in mind the location of the AC branch circuit junction box, or any other obstructions. 2. Mount and attach a MicroGT inverter at each of the identifi ed locations using hardware recommended by the PV module racking vendor (Figure 5).

    Installation Step 6: Completing Installation of the MicroGT 500s Each MicroGT 500 microinverter has two removable serial number labels on the front side (Figure 10). Use these serial number labels to create your system’s microinverter array installation map. Note: The unique serial number for each MicroGT is also the ‘Inverter ID’...

  • Page 14: Operation

    AC and DC wires are pinched or damaged. Be sure all the junction boxes are properly closed. Basic MicroGT PV System Operation (w/ MagWeb GT) To operate a battery-less MicroGT 500 inverter PV system: 1. Turn on the AC circuit breaker on each MicroGT inverter branch circuit.

  • Page 15: Troubleshooting

    Solid Red – microinverter has detected a ground fault (see below). GFDI Error: A solid red LED indicates the MicroGT 500 has detected a DC voltage Ground Fault Detector Interrupter (GFDI) error in the PV system. Unless the GFDI error has been cleared, the LED will remain red and the MagWeb GT will keep reporting the fault.
