The VARTA.wall is an intelligent battery storage system that has been specially developed for the requirements of modern PV systems. Seamless integration has been made possible through the collaboration with KOSTAL, so that the storage system communicates perfectly with the inverter. This ensures smooth operation and optimal use of solar power. Customers can be sure that both systems work together harmoniously and always find the best solution for their own energy needs. The result is an increased self-consumption rate and thus a significant reduction in energy costs. Thanks to the compatibility of the PLENTICORE G3 with the VARTA.wall, users benefit from a flexible and future-proof solution that remains stable even in the face of rising energy prices and changes in the energy industry.
PLENTICORE G3 features: advanced technology for modern energy management systems
The KOSTAL PLENTICORE G3 inverter is a true masterpiece of engineering and scores highly with numerous functions developed specifically for use in photovoltaic systems. The PLENTICORE G3's outstanding features include:
1. Three MPP trackers: The inverter has three independent MPP (Maximum Power Point) trackers, which ensure that the PV system always delivers maximum power, even with different roof orientations or shading.
2. Power extension: The inverter is available for different power ranges, making it attractive for both smaller and larger PV systems. This means that the PLENTICORE G3 can be optimally adapted to individual requirements. It is available as model S with 4 kW and can be expanded up to 5.5 kW or 7 kW. For model M, the range is between 8.5 and 12.5 kW and for model L, 15 to 20 kW.
3. DC surge protection: PLENTICORE is fully equipped for all modern requirements of a solar energy system. This also applies to all the safety features of our inverters, which are 'Made in Germany'. This is also ensured by the integrable DC surge protection (type 2) in PLENTICORE. This can simply be optionally inserted into PLENTICORE as a plug-in module. The DC surge protection provides the necessary protection against induced surge voltages that can enter from the solar module side.
4. KOSTAL BackUp Switch for battery-backup power function: The third generation of PLENTICORE also has a battery-backup power function. In conjunction with the KOSTAL BackUp Switch and a connected battery storage unit, the power supply is secured in the event of a power failure – independently of the grid. And this is how it works: the KOSTAL BackUp-Switch is installed as a manual switch on the DIN rail in the sub-distribution board at the grid connection point. The minimal installation effort makes assembly and handling extremely easy. In the event of a power failure, the KOSTAL BackUp-Switch is manually switched to backup power and electricity is generated from your own solar energy system and the connected battery storage.
5. Connectivity: Thanks to the integrated communication interfaces such as WLAN and Ethernet, the PLENTICORE G3 can be easily integrated into smart home systems. This enables convenient control and monitoring of energy consumption via an app or web portal.
VARTA.wall features: The flexible battery storage system for your photovoltaic system
The VARTA.wall is a state-of-the-art battery storage system developed for use in private and commercial photovoltaic systems. Thanks to our close collaboration with KOSTAL, the VARTA.wall offers maximum compatibility with KOSTAL inverters and boasts the following features:
1. High storage capacity: VARTA.wall is available in a range of capacities, so that the right size can be selected for every energy requirement – VARTA.wall offers the necessary flexibility.
2. Modular design: VARTA.wall can be easily expanded when energy requirements change. This makes it a future-proof solution that grows with your needs.
3. Intelligent energy management: The storage system works seamlessly with the PLENTICORE G3, storing surplus solar power for times when the sun is not shining. This maximises self-consumption and minimises dependence on the public grid.
4. High efficiency: VARTA.wall is one of the most efficient battery storage systems on the market. This means that the majority of the stored electricity can actually be used.
5. Space-saving design: The compact design of the VARTA.wall enables flexible installation, even where space is limited. Thanks to these features, the VARTA.wall in combination with a KOSTAL inverter is an ideal solution for anyone who wants to maximise their self-consumption and increase their energy self-sufficiency. It is only 10 cm deep.
Sector coupling: more than just storing electricity
One significant advantage of the KOSTAL and VARTA combination is the option of sector coupling. This term refers to the intelligent linking of electricity, heat and mobility. With a KOSTAL inverter and a VARTA battery storage system, the solar power generated can be used not only for your own household consumption, but also for charging an electric car or for hot water heating. Sector coupling takes the use of self-generated energy to a whole new level. For example, surplus solar power can be fed into the heating system or used to charge an electric car. This significantly increases self-sufficiency and makes homeowners less dependent on fossil fuels.
Made in Germany: quality and reliability
Both KOSTAL and VARTA are synonymous with the highest quality "Made in Germany". The products of both companies are developed and produced according to strict German quality standards. This guarantees not only a long service life but also a high level of reliability. Customers can rely on the systems to function reliably and reduce energy costs for many years. In addition, KOSTAL and VARTA offer extensive guarantees on their products. This underlines the confidence that both companies have in their technologies.
Self-sufficiency: independence through self-consumption
A primary goal of many homeowners investing in a photovoltaic system with storage is to increase self-sufficiency. The combination of KOSTAL PLENTICORE G3 and VARTA.wall offers an optimal solution here. By storing the solar power you generate, you can maximise your self-consumption and significantly reduce your reliance on the grid. With battery storage like VARTA.wall, you can store surplus solar power and use it at a later time, for example in the evening or on cloudy days. This means that less electricity has to be drawn from the public grid, reducing energy costs and increasing self-sufficiency.
A high level of self-sufficiency also means greater independence from rising electricity prices. Homeowners who produce and store their own electricity are significantly less affected by the fluctuations of the energy market. This makes investing in a PV system with a battery storage unit a worthwhile and future-proof decision.
The cooperation between KOSTAL and VARTA, as well as the seamless integration of PLENTICORE G3 and VARTA.wall, offers a pioneering solution for those who are committed to renewable energy and want to maximise their energy independence. The combination of German engineering, high efficiency and advanced technology ensures that you benefit from lower energy costs and greater self-sufficiency in the long term.
