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. If you wish to operate the system with a Wieland plug and feed socket, you have the option of purchasing these separately from a retailer and having the plug converted by a qualified electrician.

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.

The mains and system protection (NA protection) ensures immediate shutdown of the inverter in the event of a fault (e.g. mains disconnection or mains isolation).

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.

The product meets the requirements of VDE-AR-N 4105, among others.
