Xantrex Technology SW Communications Adapter Advanced Monitoring Software, Installation Concerns

2.0 INSTALLATION

Advanced Monitoring Software

The SWCA was developed to change the SW inverter raw data output to an RS232 protocol output. The SWCA code only manipulates the inverter’s display or remote (SWRC) keypad strokes. The included DOS software emulates these keystrokes.

There are companies that have used these keystroke’s bits of information (coming out of the SWCA) to develop advanced monitoring software. This software can provide monitoring and data logging capability. Additional information on these programs can be found at www.righthandeng.com or www.mauisolarsoftware.com.

NOTE: Xantrex Technology Inc. assumes no responsibility for the use or function of these advanced monitoring software programs.

INSTALLATION CONCERNS

Multiple SWCAs

If using multiple SWCAs and multiple inverters, the green wire must be isolated from each other as shown in Figure 2-2 on page 6.

NOTE: This could be a red wire - depending on the cable installation from the SWCA).

Positive Ground or PV Ground Fault Protection Installations

When using the SWCA in inverter installations that have DC ground fault protection (PVGFP) or where the inverter is connected in a “positive ground” configuration, it is recommended that an opto-isolator be connected somewhere between the SWCA and the computer com port. Opto-isolators can be obtained through www.blackbox.com (part SP400A-R3 and PS576 - 9Vdc power supply).
