What is a DC Coupled BESS? A DC Coupled Battery Energy Storage System (BESS) is an energy storage architecture where both the battery system and solar photovoltaic (PV) panels are connected on the same DC bus, before the inverter.
This document examines DC-Coupled and AC-Coupled PV and energy storage solutions and provides best practices for their deployment. In a PV system with AC-Coupled storage, the PV array and the battery storage system each have their own inverter, with the two tied together on the AC side.
The PVS-500 DC-Coupled energy storage system is ideal for new projects that include PV that are looking to maximize energy yield, minimize interconnection costs, and take advantage of the federal Investment Tax Credit (ITC). control how much reactive power is generated or absorbed by the inverters and can be used to help regulate system voltage.
The main advantage of the DC-Coupled energy storage solution is the ability to PV clip recapture with a higher DC/AC ratio. Another major benefit is the smaller size of the inverter per PV Watt.
DC power goes to the DC/DC converter. Part of the energy is used directly by loads (via inverter). Excess energy charges the battery via the same DC bus. Only one DC to AC conversion occurs when sending power to the grid or loads. Stored energy in the battery is sent through the inverter to supply the AC load or the grid.
Diverting power from the inverter to the DC/DC comes at an efficiency cost. The battery roundtrip efficiency is approximately 93% plus twice the DC/DC conversion loss of 98.2% equals 98.2% x 93.0% x 98.2 %, and then times the 98.0% inverter efficiency to get the power out to the grid = 87.9%.
