MARSTEK MARS I SE – 6kW / 10kWh All-in-One Home Battery System
The MARSTEK MARS I SE is a powerful all-in-one residential energy storage system designed for maximum self-consumption, energy independence and backup security. This system combines a 6 kW hybrid inverter, 10 kWh LFP battery, smart energy management and emergency power supply in one compact unit.
High-Performance Hybrid Inverter
The integrated 6 kW hybrid inverter efficiently converts solar, grid or battery power into usable AC electricity. This ensures optimal energy usage and significantly reduces electricity costs.
With dual MPPT inputs, the system supports up to 12 kW of solar input, maximizing solar yield even with multiple roof orientations or partial shading.
Expandable up to 60 kWh
The MARSTEK MARS I SE starts with 10 kWh storage capacity and can be expanded up to 60 kWh using external battery packs.
Ideal for:
-
growing energy demand
-
expanding solar installations
-
full home electrification
-
small commercial applications
Each battery operates independently for optimal performance and long-term reliability.
Scalable Power up to 24 kW
Up to four units can be connected in parallel, providing a total output of 24 kW. This makes the system suitable for large homes or high-load environments.
Emergency Power Supply (EPS)
With an automatic switchover time of <10 ms, the MARS I SE ensures uninterrupted power during grid outages. Essential appliances remain operational without interruption.
The system is also generator compatible, offering additional backup security.
Smart Energy Management & Anti Feed-In
When combined with a smart meter, the system prevents unwanted feed-in to the grid. All generated energy is used internally or stored in the battery, maximizing self-consumption and financial return.
Ultra-Silent Operation
With a noise level below 30 dB, the system operates silently and is perfectly suited for indoor installation.
Intelligent Monitoring & App Control
Monitor and control your energy usage in real time via the smart app:
-
