[RE-wrenches] Small scale Maximisers/Optimisers.....

[Allan Sindelar]

Glenn, I don’t believe that UL listing is optional. I don’t believe it’s even available, nor even desirable, for a small component such as this. For an item that’s made in small quantities to serve a niche market, and low voltage DC at that, I can’t imagine what advantage UL listing would offer, especially if now a $150 product cost $250 to cover the cost of the listing process. 
Just sayin’...

They tend to keep the pump operating when a cloud goes over or in low-light conditions.    I think they are available for the 9325 but its probably over-kill for the Flojets.
