Get to know the APsystems EZ1 plug-in microinverter and APmeter, from unboxing and setup to real-time energy monitoring in the AP EasyPower app!
The EZ1 converts solar power into usable electricity for your home, while the APmeter monitors energy flow. Together, they enable app-based monitoring and zero-export control to help prevent excess solar power from feeding back into the grid.
In this video, we walk through:
☀️ EZ1 and APmeter features
📦 Unboxing and included accessories
🔌 Installation and connection basics
📱 Device setup in the AP EasyPower app
⚡ Export limits and real-time energy monitoring
Whether you're exploring plug-in solar or getting ready for your own installation, this walkthrough shows how everything works together!

MATT MAKES SOLAR EZ: PRO TAKE
Could a plug-in solar setup really pay for itself in under two years in California?
Matt runs the numbers using a two-panel EZ1 system, estimated equipment costs of about $700, California sun hours, real-world production conditions and an average electricity rate of roughly $0.34 per kWh.
His estimate: around $370 in annual electricity savings, with a simple payback of under two years.
Actual production and savings will vary depending on panel placement, shade, local electricity rates and how much of the solar power you use in your home—but Matt’s quick breakdown gives you a good place to start.

Plug-in solar is moving from a niche concept to a growing part of the U.S. solar market.
In a new feature from Solar Power World, APsystems USA Country Director Doug Hewitt discusses the momentum behind balcony solar, the growing demand for DIY energy solutions and how products like the APsystems EZ1 are making solar more accessible to homeowners and renters alike.
“The market is telling us that people are actually really interested in this,” Hewitt said. “It’s giving everybody a chance to go solar. I think it’ll be huge.”
As more states open the door to plug-in solar, we’re excited to help make generating your own energy simpler, more flexible and more accessible.

Before APsystems microinverters power your system, they pass multiple rounds of rigorous testing.
🌦️ Cold. Heat. Water. Salt spray.
Laboratory testing verified stable operation of APsystems microinverters across temperatures from −40°F to 149°F (−40°C to 65°C). IP67 water protection remained effective after one hour of immersion at a depth of approximately 3.3 feet (1 meter), while corrosion resistance testing further verified performance in demanding salt-spray environments.
For installers, partners, and project customers, long-term confidence begins with evidence. Here, that evidence comes test by test, across the conditions that shape real-world performance.

Plug-In Solar Gets the Green Light in California!
Congrats, California! With SB 868, the Plug and Play Solar Act, now signed into law, California becomes the 10th state to legalize plug-in solar.
It’s a big step forward for plug-in solar and products like the APsystems EZ1 Plug-In Microinverter. Pair the EZ1 with the APmeter for smart zero-export control where needed.
The new law opens the door for more homeowners and renters to generate their own clean energy. Taking effect January 1, 2027, it sets safety requirements and allows qualifying plug-in solar systems to operate without a traditional utility interconnection agreement.

DIY Doug’s garage. Teddy Talks. Plug-in solar. And, thankfully, absolutely no electrocution.
In this quick EZ1 lesson, Teddy breaks down one of the biggest questions around plug-in solar: is it actually safe?
The short answer: yes.
Teddy walks through how the EZ1 connects, what its UL listings mean, and how quickly the system shuts down when unplugged or during a grid outage.
No sparks. No shocks. No garage fire. Just plug-in solar doing what it’s supposed to do.

Picking panels for an EZ1 setup? Don’t go by wattage alone. A panel can look like a match on paper but still fall outside the microinverter’s operating range.
Our free guide walks you through four numbers to check on the panel label or datasheet: Vmp, Voc, Imp and Isc. It also explains how compatible lower-wattage panels, including flexible panels, can be paired to connect up to four panels to one EZ1.
Take a look before choosing your panels: https://usa.apsystems.com/document/apsystems-pv-module-selection-guidelines-for-ez1-lv/
