Inverters are rated in terms of apparent power kVA. They may also have a real, or active, power rating in kW that is equal to or less than the kVA rating. It’s important to distinguish whether a numerical rating refers to kW or kVA, as we shall see in a later article. [pdf]

Having PCS functionality has two key benefits. First, PCS enables SunPower to install more powerful SunVault® systems without installing a new, larger main service panel. This avoids additional equipment cost to the project and the requirement to extend permit and interconnection approval. .
When PCS is enabled for utility compliance, the SunVault PCS system will operate in "Import-Only" mode. While your solar system will continue to export excess power to the grid. .
When a PCS system is used to protect the Main Service Panel(MSP), it will monitor the total loads in the home and limit the PV and the Storage if the power draw on the MSP exceeds its rating. This will appear as a loss of. A power plant controller (PPC) is an automation platform designed to manage and optimize the operation of a solar farm. PPCs utilize advanced control software to efficiently operate the plant and maintain grid stability while adhering to regulatory requirements. [pdf]
