You often hear that heat “kills” a panel’s output. The reality is more nuanced, and that’s exactly where APsystems architecture makes the difference.

Yes, a hot panel does produce a little less. It’s physics, and it applies to every installation. But the real issue isn’t one module dipping, it’s what that dip does to the rest of the system.

With a string inverter, panels are wired in a chain: the weakest module drags the whole series down. A heat spike, a bit of shade, some dirt on a single panel, and the entire row drops with it. Domino effect.

With APsystems, each microinverter manages its module independently. Each panel operates on its own. If one underperforms due to high heat, its microinverter switches to “degraded” mode, lowering conversion power to prevent damage, while the other panels keep producing at full capacity. No strings, no domino effect.

The result: stable, optimized output all summer long, even when the thermometer goes wild.

Redsun Solar LLC recently completed a unique project combining solar installations for a three-phase commercial building and an adjacent residential property owned by the same family.

“We wanted to use one platform to monitor, so naturally, APsystems microinverters were the first choice.”

The commercial system uses QT2 three-phase microinverters, while the residential property uses DS3 microinverters, giving Redsun Solar the flexibility to meet the needs of both installations within one APsystems platform.

The result was a simple installation, the right power for each application, and a finished layout the customers were extremely happy with.

 

PlugInSolarUS recently published an in-depth brand review of APsystems and the EZ1, exploring how more than 15 years of microinverter innovation helped shape our approach to plug-in solar.

Titled “APsystems — The Multi-Module Microinverter Pioneer Enters Plug-In Solar,” the article traces APsystems’ history as an early leader in multi-module microinverter technology and examines how that same design philosophy has been applied to the EZ1.

The review highlights several features that make the EZ1 stand out:

• One microinverter connects to two solar panels, reducing hardware and simplifying setup.
• Two independent MPPT channels allow each panel to operate separately, helping maintain production when one panel experiences shade or different conditions.
• Built-in Wi-Fi and Bluetooth provide direct monitoring through the AP EasyPower app without requiring a separate gateway.
• Up to 900W of AC output helps homeowners and renters offset everyday household electricity use.
• CSA certification to UL 3700 and built-in anti-islanding protection support a safe, purpose-built approach to plug-in solar.

The article also explores the optional APmeter zero-export solution, which monitors household electricity use and adjusts EZ1 output to help prevent excess solar energy from being sent back to the grid. As the review notes, local utility rules, permitting requirements, and electrical codes still vary and should always be verified before installation.

Above all, the article recognizes that the EZ1 is backed by APsystems’ established global experience—not created as a stand-alone entry into a new market. It brings our proven multi-module architecture, safety focus, and smart energy technology to a more accessible form of solar.
