17 PV Inverters in Stand-alone Grid Systems<br />
You will find further information on "selecting and using PV inverters in stand-alone grid and back-up<br />
systems" in the download area at www.SMA.de/en.<br />
To operate the a PV inverter in a <strong>Sun</strong>ny Island system, you must set the PV inverter parameter to standalone<br />
grid operation.<br />
Depending on the device type, you can set the PV inverter to "stand-alone grid operation" using<br />
<strong>Sun</strong>ny Boy Control, <strong>Sun</strong>ny WebBox, <strong>Sun</strong>ny Data Control or <strong>Sun</strong>ny Explorer.<br />
Changing grid-relevant parameters<br />
To change grid-relevant parameters on the PV inverter (<strong>Sun</strong>ny Boy, <strong>Sun</strong>ny Mini Central or<br />
<strong>Sun</strong>ny Tripower) you need a personal access authorization, the SMA Grid Guard<br />
password. Call the SMA Serviceline to obtain your personal SMA Grid Guard password.<br />
DANGER!<br />
Feedback may occur if the power distribution grid fails. Death or serious burns<br />
when working on the power distribution grid.<br />
If you set the PV inverter to stand-alone grid operation, it does not fulfill any country-specific<br />
standards and regulations. Therefore, in the event of outage of the power distribution grid,<br />
there is a danger of back feed.<br />
• Never operate the PV inverter directly on the power distribution grid when set to<br />
stand-alone grid operation.<br />
17.1 Setting Stand-alone Grid Operation<br />
If the PV inverter is not set ex works, you must set the PV inverter to stand-alone grid operation at the<br />
installation location.<br />
You have several possibilities to set the PV inverter to stand-alone grid operation:<br />
• Setting via rotary switch (only within the first 10 operating hours)<br />
• Setting via <strong>Sun</strong>ny Boy Control, <strong>Sun</strong>ny WebBox<br />
• Setting via <strong>Sun</strong>ny Data Control<br />
You can only carry out the setting via the rotary switch on the PV inverter within the first 10 operating<br />
hours. Thereafter you must carry out the setting via <strong>Sun</strong>ny Boy Control or <strong>Sun</strong>ny Data Control.<br />
