The hybrid storage inverter is a device that combines an inverter, which converts direct current (DC) electricity to alternating current (AC) electricity, with a battery storage system. This allows for the storage of excess solar energy generated during the day, to be used during times when the solar panels are not generating enough power, such as at night or on cloudy days. The hybrid storage inverter is often used in solar power systems for homes and businesses, as it allows for greater energy independence and can help to reduce electricity costs.
As a company with 15+ years of experience in the solar field, we have an individual R&D team and manufacturing capability. With 2 manufacturing bases, 20,000m² + production area，600+ employees, auto production lines and an international standard factory management system in Shenzhen city, we are able to control the production process, delivery date and most import quality control. Suntao is dedicated to supplying excellent products and solutions.
To date, Suntao has completed countless projects and our footprints are all over the world. From solution design to product supply, we have assisted global customers in completing off-grid/on-grid/hybrid types of residential, C&I and large-scale ground-mounted projects.
