I just finished a lengthy inverter shopping, researching, reading reviews, etc...and ended up choosing a 3k
Go Power! While my build was still in planning stages, I was certain I'd go with Magnum who's quality and reputation seems as solid as it gets. However, my solar grew into a 1000 watt beast that will stand a fair shot at running off-grid AC when complete...and I found myself shopping in the 3000 watt pure sine inverters. And that essentially put Magnum outside what I was willing to spend.
After all the research, what really tipped it to GoPower was that anywhere reviews were posted and someone had a problem or negative experience, the GoPower support team always posted a reply seeking to help. Most proactive support teams I've seen, regardless of product.
Unfortunately it's not in use yet so I can't give you a review, just thought I'd share my shopping experience...
