<div dir="ltr">We were a test site for HiQ inverters at our warehouse in Redway ca. long way from the ocean, but plenty of rain. We had to replace the "Balancers" three times due to water damage before we switched to a string inverter. even at free HiQ wasn't worth the hassle. <div>Maybe they have fixed the issues but I would not put them in any sort of challenging env.</div><div>Daniel</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr">Daniel Tittmann <div>CTO</div><div>Greenwired</div><div><a href="http://www.greenwired.com" target="_blank">www.greenwired.com</a></div><div><a href="mailto:daniel@greenwired.com" target="_blank">daniel@greenwired.com</a></div><div>707-923-2001 (office)</div><div>707-206-5088 (Cell)</div></div></div></div>

I think Enphase has gone with a ground wire in the cabling nowadays.
