Home Battery Backup Systems

End Black Outs and Reduce Power Costs with a Home Battery Backup System.

Look around your home. Your landline phone, fireplace and pilot lights (on stoves and hot water heaters) are likely gone. Our reliance on electrical power has increased significantly over the past 20 years. So when there is a power failure, we have no communications, no heat and no hot water. Our electricity-intensive society needs backup power more than ever.

Over the past few years, many of our SF Bay Area customers have experienced multiple blackouts, ranging from a few hours to a few days (or more). And these outages are happening in populated suburban areas – not just up in the remote hills. PG&E’s wildfire safety plan (called “Public Safety Power Shutoff”) will dramatically expand the scope of planned grid outages, which are intended to preempt the risk of its grid sparking more deadly wildfires. And living in California it is only a matter of time until the next earthquake hits.

Fortunately, battery and inverter technology has improved significantly over the past few years. A home battery backup system is more reliable and less expensive than conventional natural gas backup power systems – and they provide the additional benefits of reduced electricity costs, especially for customers on time-of-use rates.

In a nutshell, with these new solar battery backup and storage solutions, you can reduce your electric bill to zero – and have a reliable source of backup power regardless of the condition of local gas pipelines and the electric grid.

Battery Backup Benefits

Protect Against Blackouts

With increased grid demand, lack of infrastructure upgrades, wildfires, public safety power shutoffs, and utility company bankruptcies, the risk of depending on today’s electrical grid affects all of us. Get peace of mind with a Battery Backup System for your home.

Protect Yourself From Rate Changes and Save Thousands in Electricity Costs

Electrical rates from utility companies are constantly increasing and their time-of-use rates always seem to be lowest when your solar power system is generating power, and highest when they are not. A solar-powered home battery backup system from Cinnamon Energy Systems allows you to store the excess energy you produce, and use it when you need it most –keeping your utility bills as low as possible.

How Battery Backup Systems Work

A home battery backup system consists of a battery and controller run by intelligent software to optimize the charge and distribution of stored power.

The system connects directly to your home’s electrical system to optimize daily energy use and to provide backup power during a grid failure. It does this by taking in power from your solar panels and then strategically deploying it to essential electrical circuits within your house. Essential circuits typically include lights, appliances and outlets so you have peace of mind in the event of a power outage.

Batteries for home backup systems use the same advanced lithium-ion battery cells that power electric cars. The battery charge controller manages the peak efficiency of the charge within the battery to provide you with backup power.

1. Utility Service

Your utility provider connects your home or business to the electrical grid.

2. Main Breaker Panel

Power from the grid enters your home through a set of wires connected to your main breaker panel where it divides electricity into subsidiary circuits that feed the electrical outlets within your home or business.

3. Battery and Control System

Batteries store solar energy generated during the day and then consumed in the evening when rates are higher. Many systems also provide backup power to your home from the battery (at night) and (during the day) when there is a power failure.

4. Solar Inverter

A solar inverter takes the direct current (DC) from the solar panels and changes it into alternating current 120V/240V (AC), the power that you natively consume in your home.

5. Solar Power System

Solar Panels generate energy during the day. This energy can be stored in the battery, used directly in your home, or sold back to your utility under a net billing tariff plan.

6. Essential Loads Sub-Panel

An essential loads sub-panel is installed, which connects power from the Battery System to the important rooms and appliances in your home so you have power to critical loads when a blackout occurs.
