Micro inverter 850 W WiFi app BKW850

The ideal micro inverter for balcony power plants with high-performance PV modules with a maximum output power of 800 W at 230V mains voltage.

Two photovoltaic modules with a total output of up to 850 W can be connected per BKW850 Micro Inverter. You can use up to 10 units together per earthed socket or for feeding in, but the total power must not exceed 3.6 kW. For a 3-phase feed-in, you can use 10 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) ensures that the power of your photovoltaic panels is used optimally.

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.
