Atmoce integrates snow removal tech in microinverters

Netherlands-headquartered inverter and battery manufacturer Atmoce has developed a snow-removal function for its microinverter ecosystem.

“The Smart Snow Removal function transforms the microinverter network into a coordinated winter management system,” the company’s Technical Sales Manager for the DACH region, Daniel Kuskoy, told pv magazine at The smarter E Europe event in Munich last week. “The system uses controlled low-power operation of PV modules to gently warm surfaces and accelerate snow melt, enabling earlier resumption of generation after snowfall.”

The feature is compatible with Atmoce’s MI-series microinverters.

According to the company, Smart Snow Removal can be enabled ahead of severe winter weather, placing the system into a low-power standby mode for a defined period. Even under full snow cover, the system remains ready to activate without relying on irradiance to “wake” the array.

The function is managed via the Atmozen app, which allows remote configuration, activation, monitoring and optimisation of snow-removal cycles. “The aim is not continuous heating, but targeted operation balancing energy use and recovery speed,” Kuskoy said.

Three operating modes are available: Quick Snow Removal for rapid full-array recovery after heavy snowfall; Partial Snow Removal, which activates selected modules or strings to reduce energy use under uneven snow cover; and Scheduled Snow Removal, which runs based on forecasts or predefined time windows, including off-peak tariff periods.

Before activation, users can configure system parameters including the feature validity period, PV module short-circuit current verification, and a maximum power threshold. These settings are intended to ensure compatibility with different module types and household electrical constraints, particularly where other high-load devices such as heat pumps or EV chargers are operating.

During operation, the Atmozen app provides module-level visibility of snow-removal status, progress tracking across the array, and the option to manually interrupt operation at any time. After each event, the system logs performance data such as energy consumption, runtime, activation cycles and historical trends. The company says this can support both homeowner insight and installer-level diagnostics.

Atmoce emphasizes that correct electrical parameter configuration is required during setup, and conservative power limits are recommended during commissioning. “The system allows user interruption at any time, keeping control with the homeowner or installer,” Kuskoy said.

Beyond snow removal, the concept is positioned as part of broader residential energy management, enabling operation during low-tariff periods, power limitation, or selective module heating.

The system has been tested in cooperation with module manufacturer Longi, with the companies reporting no observed adverse impact on module performance or warranty under test conditions. Further validation with additional manufacturers is ongoing.
