Micro Inverter 500W WiFi App BKW500

The ideal micro inverter for balcony power plants with high-performance PV modules with a maximum output power of 500W at 230V mains voltage.

One photovoltaic module with an output of up to 500Wp can be connected per BKW500 Micro Inverter. You can use up to 9 units together per earthed socket or for feeding in, but the total power must not exceed 3.6 kW. With a 3-phase feed-in, you can use 9 units each with a maximum of 3.6 kW per phase.

MPPT technology (Max Power Point Tracking) makes optimal use of the power of your photovoltaic panels.

With the KKT KOLBE Control WiFi app, you are not only always well informed about the performance and status of your system, the app is also compatible with all Smart Life devices. Scenes can be created via the app in which, for example, a smart socket is switched from a certain output power.

Important: If models BKW1000 and BKW500 are connected in series, model BKW1000 must always be installed last before the feed, otherwise there may be a loss of power.

Mounting material is not included in the scope of delivery

Depending on availability, the model offered or an identical model with a different designation may be supplied.
