Solar System Control Module
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 associated with service. When PCS is enabled for utility compliance, the SunVault PCS system will operate in "Import-Only" mode. While your solar system will continue. 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.
