Atmoce MU100S Backup
Atmoce MU100-S (also written as MU100S) is a monophasic (single-phase) solar backup box and combiner unit designed for residential microinverter setups. It functions as an intelligent interface between a home’s solar microinverters, battery storage, local distribution panel, and the utility grid, allowing the system to safely transition to off-grid backup power during a black-out.
Key Technical Specifications
-
- Grid Compatibility: Configured for single-phase 220V, 230V, or 240V AC grids operating at 50/60 Hz.
- Voltage Range: Supports a phase-to-neutral operating voltage range of 184V to 276V (or up to 176V depending on regional settings).
- Current Handling: Features a maximum capacity of 80A across its main paths, including the combiner/load current, grid connection current, and bypass/distribution panel current.
- Enclosure & Environmental Protection: Rated IP65 for outdoor installation, utilizing natural convection cooling (noise levels <25 dB). It is built to operate in ambient temperatures ranging from -30°C to 50°C.
- Weight: 3.6 kg.
- Connectivity: Employs Power Line Communication (PLC) to talk to the solar gateway/microinverters, alongside integrated CAN bus and digital output interfaces.
System Integration & Functionality
The MU100-S acts as the structural protective core of an Atmoce AC-coupled ecosystem. Within a full residential layout, it bridges several components:
- Microinverters: Aggregates decentralized AC power produced directly on the roof.
- Energy Storage: Links with Atmoce MC100L PV & Battery storage controllers.
- Bypass & Safety: Houses required safety infrastructure, including Surge Protection Devices (SPD), Residual Current Devices (RCD), and circuit breakers.
- Auxiliary Generator: Supports integration with an optional external generator through an Automatic Transfer Switch (ATS) for extended off-grid durability.
