Grid-Tie Interface

For grid-tie systems with battery backup, the GTI works with Trace SW series II Inverters. It allows the Inverter to balance PV input, battery charging and utility input or sell mode. The system will sell electricity to the utility and keep a battery bank charged in case of blackout. Note the Trace SW series inverters are being discontinued and the new SW Plus series will eventually have it's own GTI.

Excerpt from the manual:

The GTI is an integrated assembly used with the Trace SW Series II inverter/charger with Revision 4.2 Software. This new device provides active anti-islanding protection and reduces current Total Harmonic Distortion below the test requirements as described in UL-1741-2000.

The GTI is an accessory, which is connected between the grid and the SW series II inverter to optimize the "SELL" feature. While there is a small inductor in the GTI, this device is not a "filter"; rather it contains an additional control microprocessor which connects to the SW series II with a communications cable.

When the GTI is connected and the Inverter "SELL" mode is selected, the microprocessor of the GTI takes control of the SW series II and operates the inverter "SELL" feature. The GTI affords a dedicated microprocessor and new, sophisticated control algorithms that are able to optimize the sell function.

The SW Series II / GTI meets all power requirements of UL1741, including harmonic distortion, power factor and anti-islanding requirements. In addition, it has increased the SW series II's efficiency in SELL mode to within 1% of the impressive off-grid efficiency of the SW.

All new SW series II units (shipped since December of 2001) are equipped to allow the GTI to be installed in the field. The SW series II inverter is Certified to UL1741 for off-grid and backup power applications. The SW can be connected to the grid as a battery charger; however, it is NOT approved to use the SELL feature (net meter) without the GTI accessory. The GTI carries all necessary approvals and markings to allow a safety inspector to approve the installation for net metering.
