3 Phase Hybrid All-in-one ESS

When the sun is shining, your PV-system usually produces more energy than what can be consumed in your home during the day. If you do not use a power storage unit, the excess electricity is fed into the public grid. At night you need to purchase electricity from your supplier. With an Wattsonic Li-HV storage system, however, you optimise the yield of your solar system for your private consumption. You also gain control of your electricity consumption and save energy, which you can use elsewhere in your home. Besides that, Wattsonic Li-HV storage system can also work as an UPS system for emergency power back-up in the areas suffering terrible frequent grid fail.

Typical Applications
