SMILE-B3 at home

SMILE-B3 is a popular choice for the retrofit situation. As an AC coupled system, SMILE B3 plugs into your switchboard just like other home appliances. It converts the AC energy to DC while charging and vice versa when discharging. Retrofit is a term we used in energy storage sector, refers to the situation of installing an energy storage system into the house where the solar panels already existed. The contrary term for retrofit is “new install”, which means the solar panels and the energy storage system will be installed into the house all at once. With original 2.9kWh storage capacity, SMILE B3 is an all-in-one system. And you could expand its capacity by simply stacking more battery modules to make best use of the solar power.
