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.
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.
In this topology, the integration of inverter and PV module is carried out in a single electrical device. It is a “plug and play” device and does not require expertise for its installation. The mismatch losses of the PV modules are eliminated in this topology . It has a modular design and can be easily expanded.
In addition, various inverter topologies i.e. power de-coupling, single stage inverter, multiple stage inverter, transformer and transformerless inverters, multilevel inverters, and soft switching inverters are investigated. It is also discussed that the DC-link capacitor of the inverter is a limiting factor.
Our standardized solar power and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
