We recently installed APSystems for the first time after our distributor recommended them for their slightly lower price and supposedly easier installation. Well, after 2 weeks of troubleshooting and trying to get it working we still have nothing, and our customer is livid. The system was turning on again after only 2 minutes after the safety switch was flipped, which is federally required to be 5 minutes. The 17 inverters we have also never all work at the same time. Its super intermittent, and the electric company won't approve it until its working all the way. APS has given us every excuse in the book. Bad signals from them to the inverters to "activate" them, bad programming in the inverter settings, bad wiring on our end, outdated firmware, wired incorrectly on our end. Every one of those was proven to not be the case, at least on our end. We had our electricians check the systems a half-dozen times to make sure it was all hooked up properly. They actually told us a couple of times we would have to leave the system on for at least 24 hours for them to test and troubleshoot it remotely, which the electric company doesn't allow before its been inspected and a digital meter has been put in. Every time we left it on for any period to test it it was just running the home owner's meter backwards and costing us money (we covered all of their down time).
Their tech support has no idea what they're doing or talking about and just kept giving us the run around. They only have 3 or 4 techs, and they're only available between 8 and 5 Pacific time. They also don't have a typical hold queue. If they're not available, which happens at least 50% of the time, you leave a voicemail and they MIGHT call you back a day or two later. They use VONAGE (not joking) for their phone service, which was spotty and had issues. They have an extremely unprofessional service and setup. And their "Engineering" department is on the other side of the world and can't do any troubleshooting during the day for US customers.
I have DOZENS of pictures and screenshots showing our testing and troubleshooting process so that everything was well documented. We are now having to remove the entire system and start over with a different brand, which is costing us over $6000 in wasted labor and materials. We are starting a fight for them to cover our losses that they caused, but I'm betting they won't take responsibility for their issues.
We will NEVER be using APSystems again. They are a huge joke. Even if they gave us a free system we wouldn't touch it. Not worth it.
I purchased a 12KW system with APS microinverters and have had nothing but problems. I must monitor the system weekly to see what inverters are not working correctly. They have suggested numerous things that I have done all with no resolve. I did purchase the system through a very reputable local company and have gone through them for all correspondence with APS. I am rating value and quality at 1 star because if they work intermittently the quality must be inferior and they have no value to me. Service, well I've been dealing with this over a year now. As far as responsiveness, I will rate them at 2 stars just because I don't know how promptly the local company informs them of my problems. Nevertheless, APS is obviously not monitoring my system or they would see these issues. Also APS has not reached out to me, the home owner, one time through all of this. APS, if you see this you can reference ECU 203000024844.
I’ve been using their products for a few years now and have been happy with the results. Chris and the tech team are a great resource and Ive found them to be very responsive. I had an issue with 2 inverters some time ago and had them replaced with no hassle. They have a pretty specific policy you have to follow to get replacements but I get that in this day and age.
I just wanted to confirm that APsystems does honor warranties. As long as the units are not altered in anyway and have been field tested. If you follow the warranty procedures they quickly send replacements out once received.
YC600A is a great product. More cost effective solution with good reliability in the field. Standard warranty 10yrs upgrade-able to 25yrs
Had a failure on system and they refuse to send replacement. Some staffing changes took place and they took care of their obligations under warranty. Raised my review from 1 star to 4 due to their correction. Thanks!
