Mikro inverterler karşılaştırması

A micro-inverter sits right next to the panels, uses MPP tracking to find the best operating point at any given moment and feeds in synchronised with the grid. It also monitors the grid and shuts down in the event of a power cut, so no voltage reaches a disconnected grid. In Germany, a certificate of conformity to VDE-AR-N 4105 is standard for this.

For balcony power plants, the output is limited to 800 watts. Devices with a higher rated output, such as 2,000 watts, must be throttled accordingly for use as a plug-in solar device – check whether this is set at the factory or done via the app.

These are the main points to compare:

If you previously had a 600 W inverter, you've been allowed to upgrade to 800 watts since Solar Package I. On some models this is done via firmware, otherwise by replacing the device. Record any changes to the system in the Market Master Data Register. Only work on the inverter when it's de-energised: first disconnect it from the grid, then unplug the panel connections.

Most micro-inverters send their data to an app via the manufacturer's cloud. That's convenient, but it means your generation data passes through third-party servers. Some devices can be read locally via Bluetooth or are supported by smart home systems. If that matters to you, check before buying whether a local interface is available. Alternatively, a smart metering plug measures feed-in independently of the inverter. Also check whether the manufacturer provides firmware updates and how long the warranty runs – longer warranty periods are common for micro-inverters.
