Sessy is scalable
Sessy monitors the output of your solar panels, the contribution of your battery, and your household consumption. This allows Sessy to precisely determine when to charge the battery with excess green energy or when to direct energy to your home. This ensures maximum savings and returns.
Thanks to the intelligent control of the integrated inverter, it is possible to expand the system to up to 6 Sessy units on a 3 x 25A main connection, with 2 units on each phase. Unlike other systems, Sessy can be upgraded at any time, allowing the system to grow with your future energy needs.
Sessy can be connected to ...
Solar Inverter
Whether you have an inverter in the attic, the shed, or micro-inverters on the roof, connecting the Sessy home battery is straightforward. This is the recommended installation method. Sessy directly monitors your solar panel production and uses this data for smart management.
Dedicated Circuit
No space at your current solar inverter, or don’t have solar panels at all? No problem! You can install the Sessy home battery on a dedicated circuit. If a circuit is not yet available, we can handle the installation for you.
Dynamic Contract with Hourly Rates
Do you have a dynamic contract with hourly rates? Sessy’s intelligent system automatically calculates based on these hourly rates to determine the optimal times to charge and discharge your battery. This process is fully automated for maximum savings, even if you don’t have solar panels!
Additionally, Sessy can further optimize energy costs by using energy during off-peak hours and storing it when prices are low. This system not only helps reduce expenses but also contributes to more efficient energy use in your home. With Sessy’s flexibility, you are always prepared for fluctuating energy prices and needs.
