APsystems Support

APsystems offers many resources to support installers with their APsystems installations. See our recommended process below as well as our available resources, such as videos, product documentation and FAQ on our website. If you have any questions or need immediate support, please fill out the form on the right to contact our support team directly.

Be aware of APsystems’ policy on self-installation. DIY installation is not recommended and homeowners should contact a licensed solar installation professional to install APsystems equipment. See the policy for more details.



Before you install APsystems microinverters, we highly recommend that you check out some available resources to learn how to install APsystems products, and learn tips and and best practices to streamline your installation. Check out our Training section to access these helpful resources.


In order to set up your residential homeowner and commercial site-owner customers with a system-monitoring account, you will need to contact APsystems using our registration form available on our Registration page.

Upon registration, you will receive EMA account information to monitor and adjust the settings of your installations. (Note: the installer registration process can take up to 24 hours.) APsystems does not register homeowners or DIY installers for EMA accounts.

Once you have completed Training and Registration, move on to Step 3: Installation.


On the job site:

  • Install APsystems microinverters and ECU following the video and installation manual instructions found in our training section and online document library.
  • Verify successful installation using the ECU App

At the office:

  • Create site owner account online in the EMA, connect it to installed ECU
  • Finalize the array configuration in the EMA, if needed
  • Provide the homeowner with their EMA account log-in
