Battery Backup In The Northwest

Keep the lights on through the Northwest power outages, use more of your generated solar energy at night, and get your home ready for full electrification with battery backup.  

What can my battery backup power?

Paired with solar, your battery can recharge during the day. That means clean, quiet backup instead of a noisy generator—and more freedom from the grid.

For most homes, there are two approaches:

Back Up The Essentials

Fridge, Wi-Fi, key lights and outlets, maybe a well or sump pump.

Whole Home

Almost everything except big “energy hogs” like hot tubs, pool pumps, or certain electric heat loads.

Energy Resilience

A home battery keeps essential systems running automatically during outages.

Stay Powered When the Grid Goes Down

Seamless Switchover

Your battery kicks in instantly, so lights, refrigeration, and key systems stay on.

Storm-Ready Charging

Systems can pre-charge ahead of severe weather for maximum backup.

Quiet, Clean Power

No noise, no fumes, no fuel—just reliable energy when you need it.

Load Shifting

Our values guide everything we do.

Energy on Demand

Store power during the day, use it at night.

Rate Optimization

Discharge during peak pricing, recharge when rates are low.

Maximize ROI

Get more value from every kilowatt-hour your system produces.

Power Your Electrified Home

Get ready for an all-electric future

Battery storage makes it easy to run heat pumps, EV chargers, and more—with reliable backup when you need it.

Flexible Backup

Power essential circuits or your entire home.

Smart Control

Scalable System

Start small and expand as your needs grow.

FranklinWH aPower 2 + aGate

A flexible home battery backup system, the FranklinWH aPower 2 + aGate stores enough energy to keep your critical circuits—lights, Wi-Fi, fridge, and well pump—powered through outages. Working together with the aGate smart panel to tie your solar, battery, grid power, and even an optional generator.

Flexible whole-home backup that grows with you

Whole-home backup with fewer batteries
Designed so a single aPower 2 can support most or all of your home’s essential loads, with the option to add more batteries if you want deeper, multi-day backup.

An industry-leading 15-year warranty means the system is engineered for everyday use, not just the rare outage, so you can lean on it for years of bill savings and backup power.

aPower 2 and aGate can work with most existing solar systems and can also tie in a generator, EV charging, and the grid to create one coordinated home energy system.

Weather-resistant housing and built-in thermal management mean the battery is built to keep working through heat, cold, rain, and wind—exactly what we see in the Northwest.

The FranklinWH app and controls can automatically prioritize stored energy during peak-price hours and tap into programs like net billing or virtual power plants where available, helping you earn more from every kilowatt-hour.

Using stable LFP battery chemistry and ultra-quiet operation, the system is designed to stay safe, stay out of the way, and simply work in the background of your daily life.

Tesla Powerwall 3

Turn your daytime solar into reliable backup power with The Tesla Powerwall 3 systems that maximize your solar energy. Storing more energy for use at night, during storms, or when rates spike. With an integrated inverter, smart software, and a compact wall- or ground-mounted design, it quietly shifts your home onto stored power behind the scenes.

Flexible whole-home backup that grows with you

Keeps your home running when the grid goes down

Automatically takes over during an outage and can be sized to back up just your essentials or, with enough capacity, most or all of your home.

Stores the extra solar your panels make during the day and uses it at night or when the grid is down, boosting your energy independence.

Built-in solar inverter means your solar and battery work together as a single, efficient system, with room to expand later if your needs grow.

The Tesla app shows, in real time, where your power is coming from and lets you choose how the system behaves—while Storm Watch can auto-charge the battery ahead of severe weather and send alerts to your phone.

Time-based controls can shift more of your home onto stored energy during expensive peak-rate hours, helping lower utility bills while you use more clean power you generate yourself.

Outdoor-rated, flood- and dust-resistant, and backed by a 10-year warranty, so it’s designed to live outside and keep working for years in Northwest conditions.
