☀️ Are you really getting the maximum out of your PV system? ☀️

Many people only look at the performance of the solar modules. But how much electricity actually reaches your household depends on the entire system! The SPI seal (System Performance Index) from HTW Berlin shows you the real efficiency in annual operation.

📉 The problem: Poorly coordinated systems eat up your returns through high standby consumption and conversion losses.

📈 The advantage: A top system easily saves you €1,665 and more over the years compared to standard devices!

🏆 Best example: The KOSTAL PLENTICORE – test winner 2026 (10 kW class). Flexibly expandable for heat pumps or e-cars and maximally efficient.

When buying, don't just look at the price, look for the SPI seal!

Fewer site visits, faster service! 🚀 The new KOSTAL Remote Access for the PLENTICORE G3 is here.

Troubleshooting, setting updates, or real-time diagnostics? Installers no longer need to get into the car for this. With the new remote access, it can be done directly from the office via the KOSTAL Solar Portal – secure, fast, and efficient. 💻✨

The highlights at a glance:

🛠️ Full access: Operate the familiar user interface of the PLENTICORE G3 remotely (all parameters, data, and error messages at a glance).

⏱️ Time savings: Drastically reduced service times and fewer on-site appointments in daily business.

🔒 Maximum security: The system operator retains full control! Activation is done directly on the device – either permanently or time-limited (e.g., for 24 hours).

What is required?
👉 PLENTICORE G3 (software from version 03.06.06###)
👉 Activated remote access & stable internet connection
👉 Matching installer role in the KOSTAL Solar Terminal / Portal

A win-win for everyone: Faster support for system operators, more efficient work for installers. 🤝

💡 Note: For security reasons, software updates cannot be uploaded via this connection.

Security is no accident, it’s a concept. 🔒⚡

Inverters are the heart of every PV system – making them a prime target for cyberattacks. KOSTAL is setting new standards to protect installers and operators alike.

Our multi-layered security concept at a glance:

🔑 Double Authentication: Access only via an individual service password PLUS a unique Master Key found on the type plate.

🛡️ Closed by Default: All ports are factory-sealed. Only necessary functions are opened after authorization.

🔐 Encryption: HTTPS standards and signed software updates protect against manipulation.

🚫 Brute-Force Protection: Automatic lockout after repeated failed login attempts.

Maximum efficiency requires maximum trust. With KOSTAL, your data and your infrastructure are secure.

⚡️ Are you getting the most out of your PV system?

Is your solar system running, but your electricity costs could be even lower?

Many systems installed between 2010 and 2018 are wasting valuable potential.

The reason: an outdated inverter that cannot communicate "smartly."Stop the waste – choose repowering with KOSTAL!

🚀 Why upgrade to the PLENTICORE G3?A modern inverter is far more than just hardware – it is the brain of your home.

By replacing your old device, you create the foundation for a Home Energy Management System (HEMS):
Intelligent Control: Use solar power exactly when it's available – for your wallbox, heat pump, or battery storage.
Full Transparency: Keep an eye on production and consumption at all times with the KOSTAL Solar App.
Future-Proof: Ready for dynamic electricity tariffs and compatible with various storage systems.
Maximum Savings: Less grid consumption, more self-consumption – fully automated in the background.
Remote Efficiency: With the latest portal version, installers can even perform setup and analysis via secure remote access, saving you time and service costs.

🎶 The conductor for your energy orchestraA HEMS networks your devices and makes smart decisions:
the EV charges when the sun shines, and the battery fills up when electricity prices are low.
Without a modern "heart" from KOSTAL, this potential remains untapped.Start your networked energy future now!

👉 Have your repowering potential checked and make your home fit for the energy transition.

🏆 Test winner 2026: KOSTAL sweeps the HTW Electricity Storage Inspection!

Efficiency is no coincidence, but the result of intelligent technology. In the current industry benchmark of HTW Berlin, our PLENTICORE G3 (in combination with the BYD Battery-Box) took 1st place in the 10-kW class (AC)! 🥇

A higher SPI value means:
- more self-consumption
- less grid power consumption
- lower electricity costs

The highlights at a glance:
🚀 Efficiency Class A: With a peak value of 93.5%.
🔋 Best conversion values: Highest efficiency from PV to battery (PV2BAT). 💤 Minimal thirst: Only 6 W standby consumption – a true top value in the market.

Whether AC or DC, 1-phase or 3-phase: For the 9th time in a row, KOSTAL proves that our systems belong to the absolute elite across all power classes.
Transparency creates trust. Rely on tested quality and become independent!
