Residential FAQ’s
Q. How can I purchase a PV Powered inverter?
A. Our products are sold through dealers and distributors. Please reference our Authrorized Distributors page and contact the company of your choosing to inquire about pricing and availability.
Q. Are your inverters UL certified?
A. Yes, all of our inverters are certified to UL1741 standards, and our integrated disconnect is certified to UL98 standards.
Q. Where are your inverters certified for use?
A. Our residential products are certified for use in the United States and Canada.
Q. Can your inverters be used in off grid applications?
A. No, our inverters are designed for use in grid tied applications and cannot be altered or reconfigured in any way for off grid use.
Q. Can your inverters work with another DC source besides PV, such as wind or hydro?
A. Our inverters are designed and warranted for PV use only. Our inverters have been used in applications other then PV but this is done at the installer’s risk and does void the warranty.
Q. Can your inverters be used with a generator to continue power generation in the event of a power outage?
A. No, our inverters are not designed to be used with a generator. If a generator is to be used on the same installation, the inverter must be installed on the utility side of a transfer switch, thus isolating it from the generator in the event of a power outage. For more information regarding this issue, please read this article from the magazine SolarPro.
Q. How does the inverter respond to a power outage?
A. All inverters certified to UL1741 standards incorporate an anti-islanding algorithm to shut the inverter off in the event of a power outage. Once grid power is restored to the inverter, it will continue normal operation after a 5 minute startup sequence is completed.
