Yeah, as long as the solar battery hybrid inverter or battery inverter is integrated with an backup function or compatible with an optional automatic switching gear(STS/BTS).
The multiple system paralleling function of residential PVESS is still under development and should be ready within 3 to 6 months. The commercial battery storage system is empowering with multiple paralleling as an extra PMS module and is added to the system solutions.
The main application scenarios or operating stategy for the energy storage will be:
a. maximizing PV self-use; b. peak shaving; c. peak power enhancement; d. backup; e. demand response etc. For large scale solution, renewable integration, frequency regualations, peak shifting are also available.
