Get QuotesAPsystems was founded in Silicon Valley in 2010 and is now a global leader in advanced solar microinverter technology. In fact, with hundreds of thousands of units installed in more than 80 countries, APsystems ranked no. 2 in global market share among independent microinverter suppliers (source: GTM Research). APsystems’ business unit for the Americas region is based in
Seattle, Washington.
Out of 34 inverters, I've had 6 fail outright so far. Getting AP to replace them is a nightmare. I currently have 1 inverter that has been dead for 2.5-months. I had a certified installer come out to diagnose the inverter as dead but AP required that it still be sent in for testing. they have had it 1.5-months now and still no resolution. They don't answer emails, they don't follow up on calls. They simply do not care about their product performance or customer satisfaction.
I would never buy their products in the future. Low quality overall!
My system is based on YS500A units and is about 6 years old and has suffered 25% inverter failures already. Getting APSystems to replace these was like pulling teeth from a gorilla on steroids. They simply never returned emails, and getting them on the phone was impossible.
The company is not self-installer friendly, by any means, and makes no attempt at hiding its disdain for this market. I simply cannot recommend them if you self-install. The jury is out on their quality for others. A 25% percent failure rate only 25% into a warranty is, well, bordering on horrible performance... A second installation is Enphase based, who were very easy to work with. Why fight to be a customer? That doesn't make sense... A company should be fighting for your business, not the other way around.
As APSystems products die, which I'm guessing they will, I'll be swapping them out for Enphase and not look back.
[UPDATE]
Now APSystems has revoked my 25 year warranty even though I have, in writing, a previous email where they said it was in force. Nice! And, another inverter failed. I ended up taking the failed ones apart and guess what? No giant surprise but the solder joints were not good on the electrolytic capacitors. So now we have a clear manufacturing defect and a company that won't honor its own warranty! I lowered my approval of APSystems to 1 star. I'd do 0 if I could. What a load of !@%$%@#
So, what do you do in a situation like this? Well, Enphase as been the polar opposite of APSystems. So, I'm yanking out half my AP inverters and replacing them with Enphase. I'll use those inverters (minus the one that has died) as my spares when the remaining half inevitably fail. Statistically, I'm on course to have all of my APSystems inverters fail within the next 5 years.
There is a simple way to describe my feelings about the company.... Solar has been one of the best things I have done. APSystems inverters have, single handedly, been one of the worst. Their ROI has been eliminated and the pain in the rear factor hasn't been worth it. I wish I never heard of the company before. I'm sticking with Enphase now and flushing my APSystems products.
While I appreciate the quality website and monitoring capabilities provided by APSystems, we have had two instances of inverter failures, and support is difficult to reach. The first time, our installer had replacements on hand. The second time, he did not. APSystems attempted to send a replacement, but they sent it to the wrong country. Neither the installer nor I received response from APSystems to multiple requests to send the replacement inverter to the proper address. Finally, was able to reach someone, and hopefully the inverter will arrive.
