Energy Hub Inverter and Backup

Interface FAQs

Q: What is Prism technology?

A: It is the software that allows for an ever-growing range of products to

be easily connected to the Energy Hub inverter. Spectrum of capabilities

includes EV charging, battery storage, consumption

monitoring/production metering, and smart energy devices, now and in

the future.

Q: Which batteries does Energy Hub support?

A: Currently the LG Chem RESU10H works with Energy Hub; a SolarEdge

battery is expected to be introduced in the near future.

Q: What are the advantages of using Energy Hub inverter over other

inverter models?

A: With a record-setting 99% weighted CEC efficiency, Energy Hub

combines the functionality of our existing home inverters in one: ready

for battery, preconfigured for Smart EV Charger, and includes built-in

consumption and production meters. And it’s future-ready: add-on

possibilities will grow as SolarEdge releases more smart energy devices.

It allows for 200% DC oversizing compared to 155% with the legacy HD-

Wave inverters.

Q: What is max backup panel amperage for Energy Hub inverter with

Backup Interface?

A: Up to 200A.

Q: What EV Chargers does Energy Hub support?

A: Energy Hub easily connects to the SolarEdge Smart EV Charger—

the only home EV charger that can charge from up to 100% solar

energy.

Energy Hub Inverter and Backup Interface FAQs Q: What is Prism technology? A: It is the software that allows for an ever-growing range of products to be easily connected to the Energy Hub inverter. Spectrum of capabilities includes EV charging, battery storage, consumption monitoring/production metering, and smart energy devices, now and in the future.

Q: Does Energy Hub support multiple Smart EV Chargers? A: Not yet – more than one would work on separate breakers, but only one behind the inverter. Q: Does the Energy Hub Inverter have a charge controller that charges/discharges the batteries when the grid is up or down? A: Yes, there is a battery management system inside the battery, and an integrated energy management system in the Energy Hub.

Q: Can the batteries be set to charge at the top of the bell curve? A: Yes, this is 'charge from clipped energy', and is a mode we support. Q: With a 200% DC/AC ratio, if the inverter is exporting max to the grid during clipping can it serve both the battery load and EV charger? A: Yes, for instance 7.6kW could flow to the grid from PV, and simultaneously 5kW can flow from PV to the battery.

Q: Is the Smart EV Charger connected on the DC or AC side of the inverter? A: It is an AC Level-2 EV Charger. Q: Can LG Chem batteries and the new Smart EV Charger both connect to one Energy Hub inverter? A: Yes. Up to two LG Chem batteries and one Smart EV Charger can connect behind one Energy Hub inverter. Q: What smart devices can be controlled through the mySolarEdge app? A: PV, battery, Smart EV Charger and Smart Energy Hot Water for now.

Q: Does the Energy Hub inverter have an RJ45 port to hardwire internet? A: Yes. There is an Ethernet connection if you prefer to hardwire. Q: Can the Smart EV Charger be installed on a non-solar site behind a dedicated 40A breaker? A: Yes. Our standalone Smart EV Charger can be installed without solar as well. However, when installed with solar the customer gets the added benefits of charging on up to 100% solar energy and the solar-boost mode feature.

Q: Since Energy Hub comes with integrated production and consumption meters are CTs required? A: External CTs are required only for partial home backup. For whole home backup, you can use the CTs already installed inside the Backup Interface. Q: How far from the utility meter can the inverter be installed? A: This is driven by code and AHJ (Authority Having Jurisdiction) – SolarEdge does not have a technical limit. Q: Is the inverter UL 1741SA certified? A: Yes.

Q: Is the Backup Interface limited by the 120% rule? A: It depends on local codes, but generally yes - this is NEC. Importantly, our solution enables PV, EV and battery to be installed behind the same breaker, so the likelihood of a main breaker derate or a main panel upgrade is significantly lowered. The clever use of relocating all of the breakers into a backup panel, and interconnecting the BUI via a load side tap means the 120% rule doesn’t apply.

Q: What are the communications options with Energy Hub inverter? A: Cellular (built-in), Ethernet or the wireless gateway. We can also interconnect inverters over RS485. Q: What is the surge capability per Energy Hub inverter? A: In backup, with the LG Chem RESU10H, it is 7kW. Q: How does the inverter island itself from the grid? Does it have an extra piece of equipment like a transfer switch? A: The Backup Interface functions to separate the home from the grid.
