Atmoce MC100-Wye-8in1 Combiner Box
Atmoce MC100-Wye-8in1 is an industrial-grade M-CombinerX combiner box specifically engineered for Commercial and Industrial (C&I) solar applications. It serves as a centralized management and safety hub designed to aggregate power output from module-level power electronics (MLPE), such as microinverters, before feeding energy into a three-phase power grid.
Key Specifications & Configuration
- Grid Connection Type: Deployed for Three-phase Wye grid connection topologies.
- Input Infrastructure: Equipped with 8-in-1 inputs, meaning it can efficiently aggregate multiple branches of microinverters into a singular panel layout.
- Physical Weight: Built as a robust heavy-duty unit weighing approximately 42 kg.
Application & Purpose
The MC100-Wye-8in1 acts as the critical bridge connecting microinverters, battery storage ecosystems, and localized site loads directly to the main distribution panel.
- Scale: It is typically deployed alongside multiple high-capacity commercial microinverters (such as the Atmoce MI-1250-2M or MI-625 series) on sub-50 kWp to mid-scale C&I projects.
- Integrated Management: It pairs natively with an internal smart energy controller (the M-Gateway MG100). This integrates physical circuit protection (breakers, RCDs) while establishing telemetry via PLC, Wi-Fi, Ethernet, or CAN bus.
- Monitoring: Power production data gathered by the combiner box syncs automatically with the Atmoce-Cloud platform and the Atmozen app for real-time string monitoring and site troubleshooting.
Safety Features
Because it functions primarily within strict safety-critical or high-requirement corporate facilities, it leans into Atmoce's core low-DC-voltage topology:
- Rapid Shutdown Integration: Helps provide module-level mitigation and immediate shutdown capability.
- Environmental Protection: Standard builds across this hardware generation carry an IP65 ingress rating, optimizing them for indoor or harsh outdoor environments.
