✅ Unmatched Safety with CATL LFP Battery Solutions:
Safety is paramount, especially when dealing with stored energy. The KSTAR BluE 3-phase energy storage system is designed with CATL LFP (Lithium Iron Phosphate) battery solutions. CATL is a world-renowned battery, celebrated for its robust and stable LFP chemistry. This system incorporates triple protection at the module, pack, and system levels, offering you unparalleled safety and reliability. Your home and family are protected.
✅ High-Power 3-Phase Output (10kW Nominal, 11kVA Max.)
This inverter delivers a robust 10kW nominal AC output power with a max AC apparent power of 11kVA, perfectly suited for larger Cypriot homes with higher electrical loads, including air conditioning units, pool pumps, and modern appliances. Its 3-phase capability ensures balanced and stable power delivery throughout your property.
✅ Exceptional PV Oversizing Capacity (Up to 200%): This is a game-changer for maximizing your solar harvest. The KSTAR BluE E10KT supports 200% oversized PV power. This means you can connect up to 20kW of solar panels to a 10kW inverter. Why is this important in Cyprus? It allows your system to generate more power during shoulder hours (early morning, late afternoon) or on cloudy days, effectively extending your peak production time and ensuring you capture more of Cyprus’s abundant sunshine, even when the inverter isn’t operating at full capacity.
✅ Seamless On & Off-Grid Parallel Operation: The KSTAR BluE 3-phase energy storage system provides versatile operation. It works perfectly when connected to the grid, but also offers on & off-grid parallel system capabilities. This means in the event of a power cut (common in some areas of Cyprus), your home seamlessly switches to battery backup, ensuring your essential loads remain powered without interruption.
✅ Modular Design & Plug-and-Play Installation
Simplicity is built-in. The system features a modular design allowing for easy expansion of battery capacity by adding more BluE-PACK 5.1 modules up to 40kwh storage. Its plug-and-play functionality streamlines the installation process, reducing time and complexity.
✅ Intelligent Monitoring via Mobile APP
Stay in control of your energy anytime, anywhere. The KSTAR BluE ESS offers comprehensive mobile APP monitoring, allowing you to track your solar production, battery status, energy consumption, and grid interaction in real-time from your smartphone. This transparency empowers you to make smarter energy choices.
✅ High Efficiency Ratings
The KSTAR BluE E10KT boasts an impressive Up to 97.6% peak PV efficiency and 97% overall inverter efficiency. High efficiency means more of your harvested solar energy is converted into usable electricity for your home, maximizing your returns.

Combines the best of both worlds for optimal flexibility and future expansion.
A hybrid-coupled system integrates elements of both DC and AC coupling. In this setup, you might have some solar panels connected directly to the KSTAR BluE Residential ESS’s DC input (like a DC-coupled system), while also having an existing or additional PV inverter connected to the AC side (like an AC-coupled system). This configuration offers maximum flexibility, allowing for diverse solar array designs and potentially optimizing energy flow based on your specific needs or future additions. It’s particularly useful for maximizing energy harvest from different panel orientations or expanding an existing system with new PV arrays.
The KSTAR BluE Residential ESS All in One 3-Phase Energy Storage System represents more than just an energy storage solution – it’s your investment in energy independence, financial savings, and environmental responsibility. With Cyprus government incentives making this technology more accessible than ever, there’s never been a better time to upgrade your home’s energy infrastructure.
