New SolarEdge inverters allow for larger systems without main panel upgrades

The new SolarEdge inverters will be integrated with power control system (PCS) technology, enabling the installation of PV systems that are more than 50% larger without requiring costly and time-consuming main panel upgrades (MPU).

With the new embedded PCS technology, the SolarEdge inverters can now monitor, balance and control the currents on the main panel busbar, resulting in the ability to install larger PV systems than allowed today by the 2020 National Electrical Code 120% rule (705.12). This means that a typical home with a 200-A main panel may be able to install up to three 11.4-kW SolarEdge inverters without going through a main panel upgrade, depending on the local utility permit.

The SolarEdge DC-coupled architecture enables up to 200% DC oversizing and storage of excess PV in the SolarEdge Home DC-coupled battery.

The PCS technology will be embedded in the new SolarEdge Home Hub and Wave inverters requiring only the current transformers (CTs) to be installed on the main panel, with no additional external connector boxes, further simplifying installation and commissioning.

“Customers are seeking to install larger PV systems on their rooftops and financial considerations play a crucial role in their decision-making,” said Zvi Lando, CEO of SolarEdge. “With the new SolarEdge inverters, installers will be able to offer their customers bigger PV systems while avoiding main panel upgrades, significantly improving the economics of PV and battery storage across the U.S.”

The new embedded PCS technology will be demonstrated at the SolarEdge booth at RE+ (Booth 3311) and is expected to be available for order by the end of the year.
