1x Balkonkraftwerk SETBKW450139523

The ideal micro inverter for balcony power plants with high-performance PV modules with a maximum output power of 400 W at 230 V mains voltage.

One photovoltaic module with an output of up to 450 Wp can be connected per BKW450 Micro Inverter. The total output must not exceed 3.6 kW per earthed socket. With a 3-phase feed-in, you can use 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).

Depending on the installation, extension cables may be necessary between the inverter and the PV module. These can be purchased separately from us.

KKT KOLBE High Performance Solar Module SP395-03BI

This bifacial premium PV module with 395 Wp output and a module efficiency of 21.68% offers a better energy yield than modules with lower efficiency even in low light conditions.

The back of the module is translucent and made of tempered glass, so both sides of the module can generate electricity. This is particularly advantageous when installed as a photovoltaic fence, carport or terrace roofing or noise barrier, etc.

Thanks to the high performance and efficiency, you save up to 170,- EUR electricity costs per panel per year.*

The 120 monocrystalline half cells, with innovative multi-busbar technology, reliably increase output.

High load capacity and minimal losses due to shading.

The solar module's low temperature coefficient of -0.24% guarantees optimal power output even on hot days.

The excellent anti-PID performance due to optimised production processes and strict quality control prevents power losses in humid weather.

Due to the "Hot-Spot-Protect" quality assurance process, all cells of the module are guaranteed hot-spot free.

The PV panel is 175.5 cm long, 103.8 cm wide and 3 cm high. The tempered glass front and rear panels with anti-reflective coating and the robust anodised aluminium frame ensure the best stability, even in strong winds (up to 2400 Pa) and heavy snow loads (up to 5400 Pa). The module can be securely mounted using standard mounting systems. The mounting system is not included in the scope of delivery.

Modules can be easily connected to each other with the MC4 connector system.

Delivery is by forwarding agent free kerbside (the modules are not carried into the home) The forwarding agent will contact you via email to arrange a delivery date with you.

How do I compare prices for balcony power plants?

The purchase price of balcony power plants is calculated in watts.

Example balcony power plant from KKT KOLBE:

Purchase price: 899.99 €
Output: 850 Wp
Calculation: 899.99 € / 850 Wp ~ 1.06 €/Wp

Competitor balcony power plant:

Purchase price: 1049.99 €
Output: 770 Wp
Calculation path: 1049.99 € / 770 Wp ~ 1.36 €/Wp

Pay attention to the price per watt peak (€/Wp), competitors are often 30 - 50 % more expensive.

*The annual savings per panel were calculated on the basis of an output of up to 435 kWh per year and an energy price of 40 cents/kWh with optimal module orientation. With higher or rising electricity prices, the savings per photovoltaic module increase.

**For the exact amount of subsidies and possible conditions, please contact your local government or advice centres.
