Recently started using and so far so good!

We just started using AP Systems as a more affordable alterative to Enphase. So far so good! Easy to install, easy to commission. The user interface of the app isn't quite as nice, but it provides the desired information.

3 phase made easy

208V 3 phase (delta OR wye) microinverters accept 4 modules each, making installation quick and easy, monitoring set up easily, too. Everything worked perfectly on start up.

Great installer support

We have been an installation partner of AP Systems for a few years now, and have nothing but great experience with their product and their service. There has been a few hiccups with the equipment but whenever there are issues, they are quick to respond and give us support which is massive as a installation company.

Simple and Easy

I have been installing for over 10 years. I haven’t found a more simple solution then AP.l, and it’s at a great price point as well. What’s even better is the time it takes to commission. At the end of the day that’s the last thing the crew wants to do is sit and wait. I’ve trained them to be able to commission in about 15 min or less. I love the new DS3 series and I hear good things about new products. Excited for the battery options as well.

Top quality low cost, great support

Love the support, high capture rate vs enphase. Lower cost, easy rma's, love the monitoring ease and quality app. Highly recommend over enphase or solaredge for sure. About the same reliability as enphase but better value, and capture more production vs iq8+.
