ON GRID INVERTER

Because of a mismeasurement, I ended up with a couple extra 400w panels when I purchased my larger array. I am using the extra panels to make a lean-to on my garage. Rather than spend hundreds on wiring to tie it in with the rest of the system, I purchased this. It comes with a couple super handy tools for connecting and disconnecting panels, a sales brochure for other products, a single sheet "installation manual", and a very nice 6 foot or so AC cable. They aren't installed in their final location, but I rigged up a test setup to make sure it works. So far the 800w worth of panels and this inverter have failed to reach 600w of output. The module seems to clip off around 580w and it will not output anything for 20 minutes or so. Then it will slowly start climbing, stay stable for a little while, then shut down again. That part is unfortunate, but after leaving the review, their customer service reached out to me and after some troubleshooting back and forth they determined I may have a faulty unit. They reimbursed me and did not request the product back. I can't give it 5 stars because of the faulty unit, but the customer service alone should make anyone feel secure getting one of these.
