Energy Hub with Prism Technology F.A.Q.s

SolarEdge Technologies | www.solaredge.com
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.
Q: Will the exterior disconnect button shut down backup loads for First
Responders, i.e. shut down all power to all circuits in the house?
A: Yes. It will turn off all power, AC and DC, PV and battery, to ensure
maximum safety.
Q: What is the Energy Hub combined system efficiency (inverter and
power optimizer)?
A: It offers record-breaking efficiency of 98 - 99% as a PV system.
Q: Can you explain the difference between the inverter efficiency
(99%) and the overall efficiency (90.8%)?
A: Energy Hub brings HD-Wave and battery backup together to deliver
the highest efficiency battery energy storage in the market. 90.8% is the
measure of an Energy Hub PV + battery system and includes round-trip
efficiency of the battery, while 99% is the measure of inverter efficiency
alone.
Q: Can we use a bi-directional meter from auto-makers to support
V2H (Vehicle to Home) charging?
A: Not yet. We are waiting for auto manufacturers to support this and it
looks like it is coming soon. This may just be a firmware upgrade—stay
tuned for updates.
