We select equipment for your application. Permanent off-grid approval, generator compatibility and available controls vary by product and configuration.

Start with the right kind of independence

No utility connection?
Or a utility you need backup for?

True off-grid living and extended outage protection need different designs. We start with your property, your essential loads and the level of independence you want.

01 / Permanent off-grid

Your own power.
Every day of the year.

For homes, cabins and rural properties operating without a utility connection. Solar, storage, controls and any required generator support must work as a complete year-round system.

  • ↗Winter production and seasonal demand
  • ↗Battery reserve and recovery after low charge
  • ↗Approved equipment and a long-term service plan

02 / Extended outage backup

Keep your connection.
Build your own resilience.

For utility-connected homes that need a plan for storms, repairs and Public Safety Power Shutoffs. Choose essential-load protection or a broader home backup design.

  • ↗Automatic grid isolation where supported
  • ↗Solar recharging and battery reserve planning
  • ↗Compatible generator coordination for longer events

Standard grid-connected solar alone generally shuts down during an outage. Backup capability requires the right equipment and configuration.

One coordinated energy system

Produce it. Store it.
Know how to use it.

Resilience comes from how the parts work together, and a design that accounts for the hours when sunshine is limited.

01

Solar generation

Plan for roof or ground-mount space, shading, winter sun, snow where relevant and the energy needed to recharge storage.

02

Battery storage

Match usable energy to run time, and inverter power to the loads that need to operate or start together.

03

Generator support

Evaluate fuel, duty rating, maintenance and approved integration. Battery charging from a generator is available only in supported systems.

04

Monitoring & controls

See production, consumption and battery status. Use supported settings and load controls to make informed power decisions.

Plan for the difficult stretch. Several cloudy days, a high-demand evening or a low battery should be part of the design conversation, not a surprise after installation.

Included with every CSS off-grid system

See your power.
Take control of your use.

Understanding what your home consumes gives you a better way to manage the energy you have.

We include system monitoring and walk you through the homeowner interface. Learn what your solar is producing, what the home is using and how much energy remains in storage.

Where supported, adjust reserve settings and manage selected loads. Scheduling laundry, water heating or EV charging around available solar can help preserve stored energy for later.

Your energy, at a glance

What you're producing

Solar output and production history.

What you're consuming

Household demand and usage patterns.

What you have in reserve

Battery state of charge and supported settings.

What needs your attention

Available system alerts and operating status.

Features vary by platform. Remote access needs connectivity; internet service, subscriptions and any ongoing service plan are reviewed in your proposal.

Understand your energy budget

Less demand.
More time from the same battery.

Try a simple example. Change average household use to see why knowing your consumption matters just as much as choosing your battery.

ILLUSTRATIVE TIME TO RESERVE
24hours

Battery energy above the selected reserve, divided by average load.

30 kWh × 80% ÷ 1.00 kW = 24 hours

kWh = energy availableHow much electricity is stored or used.

kW = power demandHow quickly equipment uses that energy.

Educational illustration, not a system size or outage-duration guarantee. Starts with a full battery; excludes solar and generator charging, conversion losses, temperature effects and battery aging. Average load does not capture motor-starting or simultaneous peak demand. Actual equipment has its own operating limits and reserve behavior.

Designed for real rural life

The details that make
the difference.

A home on acreage has different needs from a standard suburban installation. We look beyond the battery count.

01 / Water

Your well is an essential load.

Well and booster pumps need sufficient starting power. We review motor demand, water-system controls and the role of pressure or storage tanks.

02 / Comfort

Choose what needs to run.

Refrigeration, lighting, communications and selected heating or cooling come first. EV charging, electric resistance heat and other large loads need deliberate planning.

03 / Seasons

Design beyond a sunny day.

Short winter days, tree shade, snow and heavy smoke can reduce solar output. Storage and a supported recovery strategy must fit the site and season.

04 / Connectivity

Keep visibility in the plan.

Include the router and communications equipment in backed-up loads. Review cellular or other connection options and what remains available without internet.

05 / The property

Make room for safe access.

Equipment location, temperature limits, fire and building requirements, trenching and service access affect the installation. Off-grid does not mean permit-free.

06 / Long-term care

Plan for the years ahead.

Allow for maintenance, generator fuel, battery aging and future loads. We review the operating plan and expansion options before finalizing the scope.

Rural California, thoughtfully powered

From your priorities to your power plan

Designed around your home.
Explained before we build.

Your system should come with a clear understanding of what it can support, how it recovers and how you manage it.

01 / Listen

Set your priorities

Review the property, utility status, outage concerns, equipment and target backup duration.

02 / Design

Model the energy needs

Use bills or a load inventory, seasonal solar conditions and starting loads to develop the system.

03 / Coordinate

Build the complete scope

Confirm equipment compatibility, site approvals, electrical work and any generator or fuel coordination.

04 / Hand over

Commission & explain

Verify operating modes, set up monitoring and walk you through daily use, reserves and support.

Know before you build

Better questions.
A stronger power plan.

Practical answers for homes that need more than a standard solar installation.

Yes. We can evaluate that goal using your essential loads, battery capacity, seasonal solar recharge and compatible generator options. There is no universal number of backup days. Weather, starting charge, consumption and fuel availability all affect how long the system can support your home.

Potentially, with the right design. Whole-home backup does not mean unlimited simultaneous appliance use. We review well-pump and compressor starting loads, electric heating, cooking and EV charging, then determine whether extra capacity or load management is appropriate.

Some manufacturer-approved off-grid configurations require one; others depend on the design and reliability goals. A compatible generator can provide another power source during a low-sun stretch. We confirm approved duty rating, fuel supply, altitude effects and maintenance requirements for the intended use.

No. Compatibility is specific to the equipment and configuration. For example, Tesla’s published Powerwall generator arrangement does not charge Powerwall from the generator. Other approved systems can support generator charging. We verify the actual combination before recommending a design.

Loss of internet and loss of local power control are different issues. Many systems continue operating locally, while remote app access and notifications may stop. We review your platform’s behavior, local access, connectivity requirements and backup power for the router.

Often, but compatibility and existing equipment must be assessed. We review the solar inverter, electrical service, battery and controller options, and any utility requirements. Not every retrofit supports permanent off-grid use or every generator.

Yes. CSS off-grid systems include system monitoring and homeowner setup. You can review your energy information and use the controls supported by your installed platform. Whole-home consumption monitoring does not automatically provide appliance-by-appliance data; circuit-level visibility or control may need additional hardware. Ongoing monitoring service plans are discussed separately.

Start with your location, whether utility service exists, 12 months of bills if available and a list of equipment you want powered. Include well pumps, heating and cooling, EV charging and future additions. For a new off-grid home, plans and an appliance schedule help establish the load estimate.

Let's plan power for the way you live.
