Regardless of the energy storage demand, the power requirement of a project’s load profile is the most important factor when deciding whether inverter stacking or a high voltage inverter option makes sense for a project. When considering a standard 48V battery-based inverter, stacking is limited to smaller outputs.
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.
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.
That 60 kW is usually more than enough power to cover residential and even some small commercial systems. For systems larger than 60 kW, making the leap to a high voltage inverter is most often the best choice in order to achieve higher power output and cover larger loads, such as those seen in most commercial and industrial projects.
When deciding whether to stack 48V inverters or choose a higher voltage inverter, be sure to also consider the AC power demands of the project. 48V inverters are ideal for residential projects that consist of 120/240V AC loads, and high voltage inverters are best suited for commercial and industrial projects with 3-Phase 480V AC Power requirements.
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.
