<div>I ground things well, bond them together and I install "LA's at the array and at the e panel. Then I make the sign of the cross and pray for the best.</div>
<div> </div>
<div>Also a good idea to change them out every few years,,,, we really don't know how hard they work, till they fail.</div>

<br>I'm Here's an ad, point number 5 mentions that the surge protectors installed in the array combiner box "protects solar modules and blocking diodes..."<br><br><a href="http://www.citel.us/dc_surge_protection_overview2.html" target="_blank">http://www.citel.us/dc_surge_protection_overview2.html</a><br>
<br>I'm trying to gather a firm opinion on whether they are a complete waste of $$$ and time or not. Good grounding seems I would guess is the best protection.<br><br>-August<br>_______________________________________________<br>
