Can I add a Powerwall to my existing solar system?
Yes, Powerwall can be integrated with your existing solar system. Powerwall is compatible with solar inverters from SMA, SolarEdge, Fronius, Enphase micro inverter, Delta and ABB. We continue to explore compatibility with other inverter companies.
During a power outage, can my solar recharge Powerwall?
Yes, Powerwall is able to keep a home solar system running during a power outage to recharge during extended outages. When more solar is being produced than can be used or stored, Powerwall is able to turn off the solar system and turn it back on when the energy can be used again.
How large a PV system can I connect with one Powerwall?
To ensure reliable operation during grid outages, at least 1 Powerwall is required for each 7.6kW AC of solar included in the backup circuit.
Can Powerwall go off-grid?
“Off-grid” can have different meanings:
If you are looking to be less reliant on your utility, Powerwall in the Self-Powered mode provides energy independence by using less grid power. This feature is available today.
When there is a utility power outage, Powerwall and your solar power system can provide backup power to your home. This feature is available today.
If you are in a remote area without access to utility power, Powerwall and solar can offer an off-grid solution. For our remote off-grid offering, please place a deposit here and someone will contact you to discuss further.
