For Bay Area luxury residences and large estates, a residential microgrid coordinates utility service with on-site solar, battery storage, standby generation, UPS systems, intelligent load shedding, and controlled electrical loads so prioritized parts of the property can remain operational during a grid outage. Regent5 engineers the load analysis, source sizing, transfer and islanding strategy, distribution, protection, controls, and operating priorities as one estate-level system—coordinated with architects, builders, mechanical teams, security, networking, pumps, EV charging, and additional structures.
Explore energy management solutionsRegent5 designs and installs large residential solar systems as part of broader estate electrical and resilience planning in San Francisco and across the Peninsula. Array layout, roof and site conditions, service capacity, battery strategy, backup generation, distribution, controls, future EV and mechanical loads, and architectural visibility are considered together. For custom homes in Atherton, Woodside, Palo Alto, Hillsborough, Los Altos Hills, and similar communities, solar can be coordinated with the architecture and utility infrastructure instead of treated as a separate rooftop product.
Talk through a solar design for your propertyRegent5 designs and integrates estate-scale battery storage and residential UPS systems around the property's actual load profile, desired runtime, service capacity, solar production, generator strategy, equipment location and long-term service plan. Depending on the project, platforms can include Tesla Powerwall, FranklinWH, Savant Power and other engineered energy-storage and load-management solutions. The goal is not simply more battery capacity; it is a resilient electrical architecture that can prioritize refrigeration, security, networking, gates, pumps, lighting, selected HVAC and other critical estate loads while managing larger discretionary loads intelligently.
Explore intelligent energy managementStandby generators provide an endurance layer for extended outages and can be coordinated with battery storage and compatible microgrid controls. The design accounts for generator capacity, fuel, transfer equipment, load priorities, ventilation, sound, service access, site planning and architectural screening. On larger Peninsula estates—including Palo Alto, Atherton, Woodside, Hillsborough and Los Altos Hills—generator placement and utility infrastructure are planned early with the architect and builder so resilience equipment remains serviceable without becoming a visual feature of the home.
Our electrical and engineering workA resilient power system needs an operating strategy, not a collection of disconnected products. Compatible platforms such as Savant Power can provide circuit-level monitoring and load management, while battery, solar, generator, EV charging, and electrical distribution are engineered around the property's available power and priorities. Regent5 coordinates these relationships with automation, security, networking, lighting, and mechanical systems where supported by the selected equipment, creating a unified energy-management approach for both normal operation and PG&E outages.
Whole home automation platformsLuxury residential microgrid engineering begins with the electrical infrastructure: service capacity, load calculations, transfer equipment, panels and subpanels, utility interconnection, protection, inspections, and future electrification. As a California C-10 electrical contractor, Regent5 coordinates these requirements with solar, batteries, standby generators, UPS, smart electrical panels, load shedding, EV charging, single-phase or three-phase distribution, and multiple voltage requirements. This is especially important for complex Bay Area custom homes where energy codes, PG&E coordination, architectural constraints, and long-term serviceability must be solved together.
Panel upgrades and PG&E coordinationThe measure of a microgrid is a night nobody remembers: the power failed at two in the morning, the house switched itself, the refrigeration and the security and the medical equipment never blinked, and the family read about the outage at breakfast. That standard is reached in the design phase, in load calculations and switching logic and fuel planning, long before hardware arrives.

That depends on the outage goals, available generation and storage, and which loads truly need to stay online. Many estates benefit from protecting critical systems such as refrigeration, networking, security, gates, selected lighting, pumps and selected HVAC while managing or shedding larger discretionary loads.
Runtime depends on usable battery capacity, the loads being served, solar production during the outage and how aggressively the system manages discretionary loads. Regent5 models the property’s actual priorities rather than quoting a generic number of backup hours.
Not necessarily. Battery systems can be designed around grid charging and backup operation, while solar can add on-site generation and help extend outage runtime when conditions allow. The right architecture depends on the property, utility rules, equipment and resilience goals.
Often that combination is worth evaluating. Batteries can provide fast, quiet backup and load management, while a generator can support longer outages when fuel is available. The systems should be engineered together so transfer equipment, charging, critical loads and operating priorities do not conflict.
A residential microgrid coordinates multiple energy resources and loads so the property can manage power intelligently and, when designed for it, continue operating selected systems during a grid outage. The architecture can combine utility power, batteries, solar, generators, load management and the home’s electrical distribution.
Sizing starts with the loads that must remain available, desired runtime, peak power requirements, service capacity, solar production and generator strategy. A large battery bank is not automatically better if the critical-load plan and electrical distribution are not designed around it.
Yes, selected large loads can be supported when the battery, generator, transfer equipment and distribution are sized for them. The design should prioritize what must operate during an outage and manage loads that would otherwise consume backup capacity too quickly.
EV charging can be a major controllable load. Regent5 can coordinate charger circuits and load-management priorities so vehicles can charge when capacity is available without unnecessarily consuming critical backup energy during an outage.
Yes whenever both are in the project scope. Service sizing, switchgear, critical-load distribution, battery or generator interfaces, EV charging and future electrification affect one another. Coordinating them together can avoid rebuilding the electrical architecture later.
Requirements depend on the system and jurisdiction. Regent5 coordinates the customer-side electrical design, permitting interfaces and applicable utility process for its project scope, while utility approvals and interconnection decisions remain with the serving utility and local authorities.
Often yes. Regent5 first evaluates the existing service, panels, available space, major loads, transfer equipment and control requirements. The upgrade can then be phased around the existing infrastructure instead of assuming the entire electrical system must be replaced.
Regent5 can design and implement the customer-side electrical and control scope for an integrated resilience project, including distribution, load management, battery or generator interfaces and coordination with solar or other project vendors where applicable, followed by testing, commissioning and long-term service.
