The SMUD paper on testing from the MicroPlanet site says the following, but I couldn't find other reference to the PV inverter in a quick read:<br><br>"In 2004 SMUD ran a series of tests on MicroPlanet Ltd.s High Voltage Regulator (HVR) at its<br>
photovoltaic test laboratory at Rancho Seco. Using a dedicated transformer, a load bank, a welder and a<br>photovoltaic inverter, the HVR was tested for resistive loads, reactive loads, and inverter compatibility.<br>The results of the tests indicated that the HVR was capable of boosting and bucking (reducing) the<br>
voltage in accordance with manufacturer claims, as well as improving power factor."<br><br><br><div class="gmail_quote"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

All,<br>
<br>
If you are looking for voltage regulators that can be placed on a home or<br>
business, check out <a href="http://www.microplanet.com" target="_blank">www.microplanet.com</a>. They are selling these around the<br>
world for energy efficiency purposes. Bring high voltage down makes<br>
equipment run more efficiently and keeps the PV system from tripping. I'm<br>
not sure if they have tested these with PV backfeeding them. I'll check with<br>
my contact.<br>
