German-based ‘sonnen’ are one of the fastest growing technology companies and a global market leader for battery storage units. OTI Power is proud to be a sonnen Certified Installer. We can upgrade your existing solar power with the installation of their latest product – sonnenBatterie eco.
A sonnenBatterie eco integrated with solar panels allows your home to produce and store 100% of the energy it uses – depending on climate and sun exposure –enabling your home to be energy self-sufficient. With the sonnenBatterie you will always have the latest technology built in one system. Through smart Z-wave and relay control, load management can achieve an even higher level of autonomy as it makes sure, that self consumption increases when your solar production exceeds a certain level.
The sonnenBatterie will store the surplus energy generated by your PV system in times when you don’t have any need for it. The stored energy from the daytime is then at your disposal in the evening and during the night. But the sonnenBatterie is much more than just a battery, it’s an intelligent storage system that automatically adjusts the energy use so that most of your self-generated solar energy stays in your household.
