Regent5 treats battery storage as part of the home’s electrical infrastructure, coordinating generation, storage, load priorities and automation around real outage scenarios.
15 kWh LFP battery modules sized around whole-home loads, desired outage duration and future expansion.
Central coordination of grid, batteries, solar, generators and home loads with seamless backup transition.
Electrical load analysis for HVAC, pumps, kitchens, EV charging, lighting, AV, security and critical infrastructure.
Priority-based control of selected high-demand circuits to extend battery runtime during grid outages.
AC-coupled aPower 2 retrofit strategies plus aPower S direct-solar integration for complex roof planes, future PV expansion and new-build energy systems.
Standby generator integration for long-duration resilience, battery recharging and reduced generator runtime.
Main-service, subpanel, breaker, metering and backup-boundary planning for complex residential electrical systems.
Time-of-use configuration and reserve targets aligned with utility rates, outage risk and homeowner priorities.
System commissioning, monitoring setup, operating modes, smart-load controls and homeowner handoff.
Planning for additional batteries, solar, EV loads, generators and future electrical changes as the property evolves.
Where we work.
Regent5 designs, installs and supports FranklinWH aPower and aGate whole-home backup 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 studies and outage priorities through utility coordination, commissioning and long-term service.
aPower 2 is FranklinWH’s current AC-coupled home battery. Each unit provides 15 kWh of usable storage with up to 10 kW continuous battery output and is designed for whole-home backup, solar energy storage and energy management. It works with major solar inverter platforms, making it well suited to many existing-solar retrofits, and FranklinWH also offers aPower S for projects that benefit from direct solar connection.
The aGate is the central energy controller. It manages power flow between the grid, solar, batteries, generators and home loads and manages the transition between normal utility operation and backup operation.
It can provide whole-home backup for some homes, but proper design requires a load study. Large residences with multiple HVAC systems, pumps, electric cooking, EV charging or other high-demand loads may need multiple batteries or managed loads. FranklinWH states that a single aPower 2 can start a 5-ton air conditioner. The current aPower 2 platform can scale to as many as 15 batteries per aGate, providing up to 225 kWh of storage.
Regent5 can evaluate the electrical installation, battery capacity, backup loads, solar and generator integration, communications and operating settings, then recommend service or expansion work where appropriate.
It depends on the design, driven by the number of aPower 2 batteries, the aGate and any Smart Circuits, generator integration, whether solar is existing or new, service equipment and panels, battery location and conduit, and the backup-load priorities. A number without drawings or a site visit would mislead, so Regent5 scopes each system at its Showroom & Design Center in San Carlos or during a consultation.
Yes. FranklinWH supports generator integration through the aGate ecosystem. During extended outages a properly designed generator can support household loads and recharge battery storage.
