en.Wedoany.com Reported - Dutch inverter and energy storage system manufacturer Atmoce has developed a smart snow removal function for its MI series microinverter systems. This function generates heat by controlling photovoltaic modules to operate at low power, accelerating the melting of snow covering the module surface, thereby enabling earlier power generation recovery after snowfall.
Daniel Kuskoy, Technical Sales Manager for the DACH region (Germany, Austria, and Switzerland) at the company, stated that the smart snow removal function transforms the microinverter network into a coordinated winter management system. The system can be activated before severe winter weather arrives, putting the modules into a low-power standby mode. Even when modules are completely covered by snow, the system can remain in standby mode without relying on solar irradiance and "wake up" the photovoltaic array.
This function is remotely configured, activated, monitored, and optimized for snow removal cycles via the Atmozen application. The goal is not to continuously heat the modules, but to perform targeted operations that balance energy consumption with recovery speed. The system offers three operating modes: Fast Snow Removal for rapid full power generation recovery after heavy snowfall; Partial Snow Removal to activate only specific modules or strings when snow accumulation is uneven, reducing energy consumption; and Timed Snow Removal for scheduled execution based on weather forecasts or preset time periods.
Before activation, users can configure multiple system parameters, including the function validity period, photovoltaic module short-circuit current verification, and maximum power threshold. These settings are designed to ensure compatibility with different module types and household power limitations, especially when high-power devices such as heat pumps or electric vehicle chargers are operating simultaneously. During operation, the application provides module-level snow removal status information and the overall system melting progress, and supports manual interruption at any time. After each cycle, the system records data such as energy consumption, operating time, activation count, and operation history.
Atmoce emphasizes that correct electrical parameter configuration is required at startup and recommends setting conservative power limits during the installation phase. The company also views this technology as part of a broader residential energy management strategy, supporting operation during low electricity price periods, power limiting, or selective module heating. The system has been tested in collaboration with module manufacturer Longi, and both companies stated that no adverse effects on module performance or warranty were observed under test conditions. Atmoce indicated that it is continuing verification work with other photovoltaic module manufacturers.
