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

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: Can I use this solution to provide home backup and/or self-
consumption for a 120/208Vac service?
A: Not at this time – it is designed for 120/240 Vac.
Q: Is the Backup Interface compatible with the legacy HD-Wave
inverters?
A: It is, but the legacy HD-Wave inverters will not work with batteries. For
that, you need an Energy Hub inverter.
Q: Does the Backup Interface have Canadian Certification?
A: Yes. It is CSA 22.2 certified. Even our Smart EV Charger has Canadian
certification.
Q: What are the upgrade possibilities on the legacy HD-Wave
inverters?
A: Any HD-Wave inverter can be upgraded to EV charging: a solar-boost
kit is available. Consumption Monitoring can also be enabled by
installing CTs. You can also install smart energy devices like Smart Energy
Hot Water, smart switches and relays. For battery, you need an Energy
Hub.
Q: Can I install the Energy Hub inverter now and add the Smart EV
Charger and Batteries with Backup Interface later?
A: Absolutely. When we say: “We power the future,” we mean it. Upgrade
anytime, no matter how far down the line.
