SolarEdge Technologies released the latest version of the SolarEdge Home Hub and Wave inverters in the U.S. These new SolarEdge inverters will be integrated with power control system (PCS) technology, which will allow for the installation of PV systems that exceed the National Electrical Code 120% rule while avoiding main panel upgrades (per the local utility permit).
The embedded PCS technology allows the inverters to monitor, balance, and control the currents on the main panel busbar. So, a typical home with a 200 A main panel would be able to install up to three 11.4 kW SolarEdge inverters without going through a main panel upgrade, according to SolarEdge.
“Customers are seeking to install larger PV systems on their rooftops and financial considerations play a crucial role in their decision making,” says 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 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.
The new embedded PCS technology is expected to be available for order by the end of the year.
The SolarEdge dc-coupled architecture also enables up to 200% dc oversizing and storage of excess PV in the SolarEdge Home dc-coupled battery. SolarEdge also says software upgrades should allow for faster commissioning.
