Concept by US, a Florida, USA-based start-up, claims to have launched the world’s first truly plug-and-play system for residential solar energy storage.

Two weeks ago the four-year-old firm unveiled an integrated storage unit called the Powerstation 247, which comes with up to three hybrid inverters, solar maximum power point trackers, a charge controller and lithium-ion batteries.

All the equipment is made by Concept by US except for the batteries, which are lithium iron phosphate products supplied by CALB USA and chosen for their safety properties.

To install the Powerstation, an installer just needs to plug the leads from a customer’s solar panels in one end and attach it to the household distribution board at the other, said Sara Kissing, vice president and chief operating officer.

Most of the two to three-hour installation time is taken up by the battery management system software’s automated setup process, she said.

Energy storage start-up JuiceBox aims to upset residential players such as Tesla and Sonnen with what it claims is an easier-to-install product.

JuiceBox Energy’s 5.5kW, 8.6kWh lithium-ion storage system might not have the sleek lines of competing products such as Telsa’s Powerwall or Sonnen’s sonnenBatterie, but is gaining followers on ease of installation.

“We’ve got to a point where you really just press a button, after you connect the wires, and it writes all the parameters into the inverter,” said Neil Maguire, chief executive of Milpitas, California-based JuiceBox.

This means solar resellers can install the system with minimal training, Maguire said. “They know they can quote on a job and get their guys in and out in one day,” he said. “We’ve trained over 100 installers now.”

JuiceBox has been seeing rapidly rising demand for its products around the US since it launched last autumn, despite the fact that residential energy storage is still not seen as being economically viable across most of America.
