Power Topology Considerations for Solar String Inverters and Energy Storage Systems (Rev. A) As PV solar installations continue to grow rapidly over the last decade, the need for solar inverters with high efficiency, improved power density and higher power handling capabilities continue to increase.
Photovoltaic and energy storage inverters are not only the "best partners", but they also differ in practical applications such as functions, utilization rate, and income.
Today this is state of the art that these systems have a power conversion system (PCS) for battery storage integrated. This application note outlines the most relevant power topology considerations for designing power stages commonly used in Solar Inverters and Energy Storage Systems (ESS). Figure 2-1.
With the additional possibility of energy storage via batteries, hybrid string inverters provide a good outlet to maximize the power utilization of the string input, and also provide an alternate pathway to supply the grid during night or low irradiation scenarios.
Unipolar offers high common-mode voltage and for a transformer-less system such as the string inverter, this can lead to high leakage current. However, the unipolar is run at half the switching frequency and has doubled frequency at the output for a comparable EMI filter design.
