More information about SAJ
Whether you want to install a residential system or are looking for a powerful system for a commercial application, we can provide you with plug-and-play energy storage systems that are quick to deploy and take the pressure off installers. Frax delivers complete solutions and support, enabling you to work efficiently and your customer to benefit immediately from a future-proof energy solution.
Why choose SAJ?
With SAJ, you are choosing a brand that delivers practical, scalable, and future-oriented energy solutions. The systems are developed with reliability and ease of use in mind, allowing you, the installer, to work faster and providing your end customer with a stable solution for their daily energy needs. Because SAJ solutions are often designed as all-in-one systems, you can achieve a complete installation that is ready for smart energy management with fewer separate components.
SAJ systems are also interesting if you want flexibility in configuration and expansion. For example, you can work with battery modules of 5 kWh each and use multiple batteries per inverter, depending on the type of system and the desired capacity. Features such as UPS capabilities and the option to integrate an EV charger also make SAJ solutions attractive for situations where continuity, comfort, and future-proofing are important.
Energy solutions from SAJ
SAJ is a manufacturer of innovative solutions for energy storage and energy management, with a strong focus on hybrid systems that combine inverters, battery storage, and smart control. The Frax range includes SAJ all-in-one hybrid systems for both single-phase and three-phase installations. These energy solutions are designed to store energy, distribute it intelligently, and optimize its use within a home or commercial building, without unnecessary complexity during installation and commissioning.
For residential applications, SAJ offers AS3 and HS3 all-in-one solutions, for example, with a choice of single-phase and three-phase variants. These systems combine a hybrid inverter with expandable battery modules, allowing you to scale up flexibly when energy consumption increases or when you need more storage capacity. For larger applications, there is also the CHS2, a complete cabinet solution for outdoor installation with integrated components for intelligent energy management and high usable battery capacity.
SAJ inverter
SAJ inverters are at the heart of many energy solutions in the Frax range. In SAJ's all-in-one systems, the inverter and battery storage are cleverly coordinated to provide you with an efficient and user-friendly package that suits your installation. Depending on your situation, you can choose a single-phase or three-phase inverter, with power ratings to suit different energy needs.
SAJ products for better energy management
Good energy management is all about control: you want to use generated energy more intelligently, limit peaks in consumption, and gain more control over costs and performance. SAJ products such as hybrid inverters and complete energy storage systems help you store energy when there is a surplus and make it available later when you consume more than you generate. This increases your self-consumption and makes your installation more efficient and stable.
For larger installations, SAJ can also offer a robust platform for intelligent energy management, such as the CHS2 cabinet solution, which is designed as a fully pre-programmed system. This allows for faster implementation and immediate performance control without the need for manual configuration. In practice, this means that you can better align your energy consumption with generation, storage, and consumption profiles, so that you are less dependent on the grid and your installation functions optimally within the available capacity.
