What is a Kostal solar inverter?
KOSTAL solar inverters are the heart of every PV system and therefore the interface between the solar modules and the power grid, and are characterised by their particularly high efficiency and reliability.
How can energy be stored with a Kotal hybrid inverter?
Energy can be stored in various ways with KOSTAL hybrid inverters. Choosing a hybrid inverter is particularly worthwhile when building a new solar system or replacing an existing PV inverter. In existing PV systems, the storage option can be easily retrofitted thanks to the KOSTAL battery inverter.
Why do I need an inverter & a Kostal smart energy meter?
Connection to the PLENTICORE plus inverter and the KOSTAL Smart Energy Meter enables maximum flexibility and intelligence. To achieve a maximum degree of self-sufficiency, the connection of one (or more) batteries to the inverter is essential. If more energy is produced than required, the inverter stores the excess energy in the battery.
What is a Kotal solar inverter?
KOSTAL solar inverters are called string inverters. This means that several solar modules (generators) are connected in series and form a string. The direct current (DC) energy generated by the solar modules is then converted into alternating current (AC) by the inverter and can be consumed in the household's own grid or fed into the public grid.
Which inverter is best for your solar system?
Be it a solar, hybrid or battery inverter, KOSTAL inverters are the perfect application solution for every requirement and for every size of system. Distinguished on numerous occasions for its efficiency. KOSTAL inverters can be used flexibly and are suitable for any PV system.
Why should you buy a Kotal inverter?
Almost all KOSTAL inverters are equipped with several MPP trackers for the best possible and smartest energy production, regardless of roof direction. They are also equipped with intelligent technology. For optimum performance throughout the house. Can also be integrated into the Smart Home.
