  • "Immediate Faulty Inverters"

    Reviewed Jun 10, 2022

    When we first installed your micros in 2019 we immediately had one faulty microinverter. We reported the micro to you all and you sent us an RMA. A few months after we installed the RMA 6 more micro inverters went out. I reported the issue to your technical service department and they indicated it was either and AC or DC issue. We went on the roof, took measurements and submitted photos as proof that is was not a wiring or breaker issue. We did this on THREE separate occasions because AP Systems wanted to be sure it wasn't an RMA issue. Please understand it takes time and resources to deploy and team, uninstall panels then reinstall panels.

    Finally, last month (March 2022) AP Systems sent six new RMA micros. We installed the micros and system is working properly. Upon the most recent install it was the FOURTH time we had to get on the roof and deinstall and reinstall the panels. Not to mention the customer has had less than half of their system working for over a year.

    My question is do we get reimbursed by AP Systems for all of the unnecessary work that we had to perform due to receiving faulty micros? Does the customer get any type of reimbursement for having to pay a higher utility bill than expected, stretching out their assumed payback period because I installed faulty microinverters?

    I’ve reached out to everyone with no response. So I had to leave a public comment. I really hate doing this.

    As an installer, we STOPPED installing this garbage. I am surprised the AP Systems still in business. Price point was the Entry for us but soon we realized that between their product and their customers support to get replacements was costing us more money.

    "Horrible customer service; marginal product overall"

    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!
