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.
Where we work.
Regent5 designs, installs and supports Tesla Powerwall 3 whole-home backup and solar storage across the San Francisco Bay Area and Northern California. Select engagements extend to Santa Barbara, the Los Angeles area, and Orange County. Projects include custom homes and estates, from load sizing and utility coordination through commissioning and long-term service.
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.
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. Powerwall 3 has substantial motor-start capability, but actual compatibility depends on equipment size, starting current and other simultaneous loads, which are evaluated during system design.
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.
It varies by home, driven by how many Powerwall 3 and Expansion units the loads require, the backup equipment the service calls for, whether solar is new or existing, panel architecture, battery location and the motor loads the system must start. A number without drawings or a site visit would mislead, so Regent5 scopes each installation at its Showroom & Design Center in San Carlos or during a consultation.
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.
