The APsystems EZ1-LV Microinverter is the 3rd generation of dual microinverters engineered specifically for balcony, garden, garage, and carport DIY solar applications. Featuring 2 independent MPPT input channels with high input current capability (18A x 2), the EZ1-LV seamlessly adapts to today's larger solar modules (315Wp to 660Wp+) to deliver up to 900VA of continuous 120V AC power.
Key Features & Highlights
- Dual Independent MPPT Channels: Each solar panel connects to its own independent MPPT input, ensuring shading or dust on one panel does not reduce the power yield of the second panel.
- Built-in Wi-Fi & Bluetooth Connectivity: Connect directly with your smartphone via Bluetooth for instant local data viewing, or link to a router through Wi-Fi to send performance data to cloud servers.
- Convenient Plug-in Grid Connection: Connect the microinverter to a standard 120V wall outlet using the optional APsystems 5-meter AC power cord (18AWG wire, 120V US standard plug).
- Rugged Outdoor Reliability: Type 6 environmental enclosure with natural convection cooling (no internal cooling fans) and integrated safety protection relays.
- AP EasyPower App Integration: Easily view real-time system performance and monitor up to 4 units directly through the AP EasyPower mobile app.

📌 Important System Notes & Regulatory Compliance
- Local Compliance & Interconnection: Installation and operation must comply with local utility interconnection requirements, power company regulations, and National Electrical Code (NEC) standards in your area. Depending on local AHJ guidelines, grid-tie connection may require utility notification, a smart meter upgrade, or a dedicated circuit.
- Supplemental Power Solution: The EZ1-LV system is best suited for low-power, supplemental daytime solar power harvesting to offset household baseload, rather than replacing full-home electrical demand.
- Grid-Tied Operation Only: Engineered strictly for grid-tied operation. The EZ1-LV microinverter will automatically shut down during power grid outages for safety (anti-islanding protection) and cannot function off-grid without an external battery/hybrid inverter system.
- Application Scope Notice: Specifically designed and rated for balcony, garden, garage, patio, or carport DIY scenarios. The EZ1-LV is not suitable or intended for traditional rooftop solar applications.
