Overview
In regions with relatively high electricity prices, in order to comprehensively enhance the self-generation and self-consumption rate of photovoltaic systems and effectively reduce power purchase expenses, Goodwe ES or EM series energy storage inverters can be selected to build an intelligent photovoltaic energy storage system, making power management flexible, efficient and convenient. Meanwhile, this solution is also highly applicable to regions with limited power supply and those that aim to achieve peak-valley power regulation.
Function Introduction
• Increase self-generation and self-consumption rate: During the day, the electricity generated by photovoltaic modules can be provided to local loads or connected to the power grid through energy storage photovoltaic inverters, and can also be used to charge energy storage devices. At night, the electricity in the energy storage devices can be released as needed to meet the electricity demand. The maximum self-generation and self-consumption rate of electricity can be effectively increased to 95%.
Peak-valley regulation: By setting the time for charging and discharging the battery (charging the battery during periods of lower electricity prices and releasing battery energy for local load use during periods of higher electricity prices), the energy storage photovoltaic inverter can flexibly control the storage and release of electricity.
• Power supply for critical loads: When the power grid is cut off, the system can seamlessly switch to standby mode within milliseconds to continuously supply power to refrigerators, routers, lights, computers or other small devices.
