system with the help of this new product to realize photovoltaic self-use and residual power storage, and arbitrage by com- bining energy storage peak and valley to maximize economic benefits and effectively mitigate the load impact on the distri - bution grid. Four series of new products of ‘Photovoltaic Storage’ cover: large series of 80-136kW, 10-20kW three-generation inverter, 5-20kW three-phase grid-connected inverter and HYD inverter , and high-voltage and low-voltage batteries. 1). 80-136kW large series inverter: with the maximum efficien - cy of 99% suited for large-scale industrial and commercial and ground power stations. It has IP66 protection grade, 12-chan - nel MPPT design, advanced AC / DC dual power redundancy design, built-in high-precision intelligent string detection and other functions, which can better adapt to wind, sand, rain, snow and other complex and harsh environment. 2). Third-generation 10-20kW inverter: The inverter has high cost performance. It’s features include lightweight design, simple and fashionable - suitable for home environment and is easy to install; interior of the inverter adopts heat dissipation technology, and selects new generation of international brand components having longer service life; efficient; multiple pro - tection is adopted inside to guarantee service life of the invert- er and increase time limit of users’ stable income. 3). 5-20kW three-phase HYD 5-20KW inverter: It is mainly used in large household energy storage system and small and me- dium-sized industrial and commercial energy storage. This machine integrates PV and energy storage, and can realize multiple working modes of off grid and grid connection. 4). Low voltage and high voltage series batteries: It’s features include convenient installation, strong compatibility, long cy- cle life and rich communication. This strong return provides a broader space for domestic users in the choice of energy stor- age batteries. ENERGY STORAGE 43 energetica INDIA- July-Aug_2020
