Energy storage system is an important part in the power production process, which can effectively use the power equipment and reduce the power supply cost. All energy storage technologies are of great strategic significance to the construction of smart grid. Energy storage system is more important energy storage inverter, energy storage inverter is the mains alternating current, converted into DC to battery (battery) charging and storage, when the mains power failure and then the battery storage DC into mains 220 volts AC for household appliances to use.
Pure Sine off-grid or on grid solar power systems have its certain limitations in in practical use, while Hybrid solar Inverter has the advantages of both. And now hybrid solar inverter is very hot selling in hte market. Now let us take a look at several working modes of the hybrid inverter.
Selling First: This Mode allows hybrid inverter to sell back any excess power produced by the solar panels to the grid. If time of use is active, the battery energy also can be sold into grid. The PV energy will be used to power the load and charge the battery and then excess energy will flow to grid. Power source priority for the load is as follows: 1. Solar Panels. 2.Grid 3. Batteries (until programable % discharge is reached).
Zero Export To Load: Hybrid inverter will only provide power to the backup load connected. The hybrid inverter will neither provide power to the home load nor sell power to grid. The built-in CT will detect power flowing back to the grid and will reduce the power of the inverter only to supply the local load and charge the battery.
Zero Export To CT: Hybrid inverter will not only provide power to the backup load connected but also give power to the home load connected. If PV power and battery power is insufficient, it will take grid energy as supplement. The hybrid inverter will not sell power to grid. In this mode, a CT is needed. The installation method of the CT please refer to chapter 3.6 CT Connection. The external CT will detect power flowing back to the grid and will reduce the power of the inverter only to supply the local load, charge battery and home load.
