Introducing Steltec, a dynamic company specializing in energy storage solutions. With a strong focus on innovation and sustainability, Steltec has developed an impressive product range. We've had the opportunity to meet them at InterSolar Europe in Munich and have a look at their newest storage systems.

Prior to the fair, Steltec had already introduced the Focus L1 and Focus H1 systems, featuring modular designs for low voltage and high voltage applications. We will briefly recap the benefits of these systems and make a comparative analysis against other brands in the market. Additionally, we will explore Steltec's latest products, highlighting their functionality and easy of installation. Everything you need to know as an installer will be addressed so you can make the best choice for your clients' needs.

The new arrivals further improve the Low Voltage range with new mounting and configuration choices:

The 3U Series: Basic L1

A floor-mounted system includes handle bars and a stacking system with each battery module. No hassle with extra options or additional components. Each battery module has everything you need to start a new system or expand an existing one.


The LV Series: Flex L1

As the name implies, the Flex L1 offers more versatility in placement and expansion when compared to the Focus L1 wall mounted systems. The Flex L1 is mounted on a wall bracket and doesn't have a supporting base on the floor. This allows for better placements depending on the clients' home situations.


Basic L1 and Flex L1 scalability

See the table below for a quick overview of the Flex L1 and Basic L1 modules and scalability

System Dimensions (mm) Weight (kg) Scalability
Flex L1 520 x 141.5 x 470 48.0 15 parallel
Basic L1 440 x 550 x 130 46.0 15 parallel


All-In-One series: E-home 

A popular method is to incorporate the battery system and hybrid inverter. The all-in-one solution is easily configured using the original Focus L1 battery modules and Steltec's own HB5000 inverter, enabling 5kW EPS functionality and up to 15.66kWh storage capacity.
