When upgrading the grid-tied system to an energy storage system the only part that changes is the AC Coupled battery inverter add-on. The existing solar PV system doesn’t need to change at all. The AC coupled battery inverter is installed alongside batteries which is then connected directly to your panel or mains.
New installations for PV systems that include an energy storage option will most likely make use of a PV inverter that has an integrated power stage to couple the energy storage to the DC bus. This approach reduces the amount of power conversions between electricity generation, storage, and water consumption, as shown in Figure 1 b).
The energy storage system of most interest to solar PV producers is the battery energy storage system, or BESS. While only 2–3% of energy storage systems in the U.S. are BESS (most are still hydro pumps), there is an increasing move to integrate BESS with renewables. What is a BESS and what are its key characteristics?
This means that the average power consumption is between 350 and 800 watts. During the evening and overnight, when most of the battery discharging takes place, this is significantly lower, meaning that the inverter must be highly efficient, especially in the power output range from 250 to 750 watts.
For the discussion in this article, a nominal power rating in the range of 11 kW is assumed, which is expected to be in the power range of most residential PV systems. As a system of this power range is interfacing to the grid with a three-phase connection, the DC link voltage is around 800V, mandating the use of 1200V semiconductors.
This can be achieved with a local energy storage system (ESS) and, in principle, two approaches can be followed for adding an ESS to a PV system. AC-coupled energy storage systems can be added to existing PV installations that already have an existing PV inverter without an integrated storage option.
