900W APsystems EZ1 Plug-In Microinverter

Already have solar panels, or want to build your own setup? The APsystems EZ1 is the piece that turns panel power into electricity your home can use.

Connect up to two panels, plug the EZ1 into a suitable outlet, and your home uses your solar power first, so you buy less from the grid while the sun is shining.

• Use panels you already own, or build your own plug-in solar setup
• Connect up to two panels, one per input
• Plugs into a standard outlet with its attached 16.4 ft (5 m) cord
• Watch your solar production in the free AP EasyPower app

What's included

• APsystems EZ1 plug-in microinverter (12-year warranty)
• 16.4 ft (5 m) power cord with a standard US plug (2-year warranty)

Solar panels and racking are sold separately. No battery is included, so the EZ1 works while the sun is shining rather than storing power for later.

How it works

Solar panels connect to the EZ1 with standard solar (MC4) cables. The microinverter converts their power into household electricity and feeds it into your home through a standard outlet. Your home uses that solar power first, so you draw less from the grid.

Which panels work with it

The EZ1 takes up to two panels, one per input, with standard MC4 connectors. Each panel's voltage and current need to fit the inverter's input limits, and a panel's voltage rises in cold weather, so check its ratings and not just its wattage. Our 880W ground kit guide walks through a proven pairing with two 440W panels, and we are happy to help check a specific panel before you buy.

Before you install

You will need a dedicated circuit with a properly grounded, GFCI-protected outlet, and any circuit or outlet work is a job for a qualified electrician. Check the rules where you live: state, local government, your utility, and your landlord or HOA if you have one, before you buy or install. This is grid-connected equipment that works alongside your utility service, not backup power during an outage. The EZ1 is made for ground and balcony setups and is not suitable for rooftop systems.

Certifications and warranty

The EZ1 is certified to UL 1741 and UL 3700 (CSA). APsystems covers the EZ1 with a 12-year manufacturer warranty, and the included power cord with a 2-year warranty.
