Tesla Powerwall 3 and Powerwall 3 Expansion systems for whole-home backup, solar storage and energy resilience. Regent5 coordinates battery sizing, service equipment, backup boundaries, solar integration, load management and commissioning around the property’s actual electrical demands.
Regent5 coordinates Powerwall with the home’s service, solar, critical loads and automation so backup power works as part of the overall electrical design.
13.5 kWh battery modules with integrated inverter and high continuous power for modern whole-home backup designs.
Additional 13.5 kWh storage modules used to extend runtime without adding another full inverter assembly.
Power, energy and motor-start analysis for HVAC, pumps, kitchens, EV charging, lighting, networking and other residential loads.
New solar and existing-PV coordination using the Powerwall 3 integrated solar inverter or compatible retrofit architectures.
Selection and coordination of supported Tesla backup devices around the utility service, meter and panel configuration.
Breaker, bus, service and backup-boundary coordination for complex homes and future electrical upgrades.
Backup strategy for refrigeration, lighting, security, networking, automation, medical or other essential household systems.
Backup reserve, monitoring, operating modes and homeowner handoff configured around the intended energy strategy.
Verification of backup transition, solar behavior, battery charging, communications and selected household loads.
Planning for future Powerwall capacity, solar additions, EV charging, panel changes and evolving home-energy loads.
Each Powerwall 3 stores 13.5 kWh of energy. Runtime depends on the home’s actual load, solar production, backup reserve and whether additional Powerwall or Expansion capacity is installed.
Tesla lists Powerwall 3 at up to 11.5 kW continuous power. Whether one unit can support a particular home depends on simultaneous loads and motor-start requirements.
Powerwall 3 Expansion is an additional 13.5 kWh battery module without its own inverter. It connects to Powerwall 3 to increase energy storage and backup duration.
Tesla supports up to three Powerwall 3 Expansion units with a compatible Powerwall 3, adding up to 40.5 kWh of battery capacity to that unit.
Yes, many homes can be configured for whole-home backup, but high-demand residences require a proper load study. Multiple batteries or load-priority strategies may be appropriate for larger electrical systems.
Yes. Powerwall 3 includes an integrated solar inverter with multiple solar inputs, allowing direct solar integration in suitable system designs.
Yes. Tesla states that Powerwall 3 can be added to existing solar systems and is compatible with major inverter brands. The exact retrofit design depends on the existing PV equipment and electrical architecture.
Depending on the project, Tesla supports backup architectures using equipment such as Gateway 3, Backup Gateway 2 or Backup Switch. The correct device depends on the service and system design.
Powerwall 3 has substantial motor-start capability, but actual compatibility depends on equipment size, starting current and other simultaneous loads. We evaluate these loads during system design.
Yes. The Tesla app provides monitoring and control of the home energy system, including backup reserve and operating behavior. Available functions depend on the installed system and software.
Yes. Early coordination helps establish service capacity, panel architecture, battery location, solar routing, EV charging and backup-load strategy before the electrical system is finalized.
Regent5 can evaluate the surrounding electrical system, loads, panel configuration, solar integration and backup goals, then recommend appropriate service, electrical upgrades or expansion work where practical.
