Re: [RE-wrenches] Surge Protection- PV

[Allan Sindelar]

Will, Many old-timers have long known that Delta lightning arrestors don't actually work to address most surges. They were first used in a product package by Ananda Power Technologies (APT), who made the first listed powercenters, and thus became the de facto standard for including basic surge protection in a system. We used them for years in our off grid systems, as an inexpensive way to address the issue when nothing else in the same low price range was available. Now that Midnite makes a better replacement at not much higher cost, the Deltas are pretty much history for our applications.
