Israeli smart energy firm SolarEdge Technologies, has unveiled the latest version of its Home Hub and Wave inverters.

The 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.

With the embedded PCS technology, the inverters can monitor, balance and control the currents on the main panel busbar, resulting in the ability to install larger PV systems than allowed today in the USA by the National Electrical Code 120% rule. This means a typical home with a 200A main panel would be able to install up to three 11.4kW SolarEdge inverters without going through a main panel upgrade.

Furthermore, 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 SolarEdge Home Hub and Wave inverters requiring only the current transformers to be installed on the main panel, with no additional external connector boxes, simplifying installation and commissioning.

Other improvements in the inverter include software for faster commissioning, and automotive-grade critical components to improve inverter reliability.

“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, chief executive officer 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 USA.”

SolarEdge developed an intelligent inverter that changed the way power is harvested and managed in photovoltaic systems. The DC optimised inverter seeks to increase power generation while lowering the cost of energy produced by the PV system.

The embedded PCS technology will be demonstrated on the SolarEdge (solaredge.com) stand at next month’s RE+ conference (www.re-plus.com) in Las Vegas and is expected to be available for order by the end of the year.
