Brian, Brad and Paul discuss the ins and outs of adding a small wind turbine to your off-grid PV installation. We also take on questions from Brad’s recent webinar on the topic.
Questions discussed in this episode:
Is there an effective blade coating for preventing ice buildup?
Assuming no ground obstructions (e.g., Arctic tundra), what is the minimum tower height to get away from the drag and turbulence?
Can you offer an opinion on mechanical furling versus electrical braking?
Do we have any experience with Pika wind and/or other higher voltage wind turbines to charge higher voltage batteries?
Can you advise a good source for NEC codes regarding wind turbines?
What’s your experience with AC-coupled systems? Specifically marrying solar with an SMA inverter, batteries, SMA Sunny Island with backup generator on-site too. Is adding a small turbine to this mix easily done or more trouble than its worth?
How do you stabilize the wild AC Voltage and frequency?
Do turbines always have to have a battery?
