Lights: 1 Kwh Per Day
| CFL/LED equivalent to 25 W incandescent | 0.008 kWh per hour |
| CFL/LED equivalent to 150 W incandescent | 0.038 kWh per hour |
Compared to larger appliances, lights require very little electricity, especially if you have compact fluorescent or LED bulbs. Even at the high end, a 38W LED bulb or 150 W incandescent bulb uses just 0.038 kWh per hour.
So if you budget 1 kWh of battery storage per day to lighting, you could run 26 bulbs for 1 hour each more than enough to provide light for trips to the bathroom, closet, and getting ready for bed.
Remaining battery budget: 6 kWh
Can I Install A Battery Backup If I Already Have Solar
Yes, in most circumstances, you can. A battery backup system can retrofit most existing home solar systems. In this case, a homeowner will usually have a few different brands that make up their solar electric system. Contact us, and we will be able to tell you if your current solar configuration supports adding a battery backup.
Fuel Supply For Your Backup Power
The source of energy for your home backup power system is another consideration when youre comparing your options.
Generators are usually powered by diesel, liquid propane, or natural gas. Your generator can continue to run as long as you have the fuel to supply your generator, and some generators can even be connected to an existing natural gas line. If you dont have access to a natural gas line, you should expect to refill your generator as needed.

- Please work with a qualified electrician or contractor to ensure your storage is installed safely and legally. See this guide for more information.
Size/power Load For Backup Power Options
When youre comparing your backup power options, think about what you need to keep running when the grid goes down.
If you just want to keep the lights on in a power outage, most batteries will do the job. Many homeowners who choose batteries for backup power are comfortable knowing that critical loads like power outlets, lights, and small appliances will be powered in the event of a power outage.
However, not all batteries are capable of quickly discharging enough electricity to get energy-intensive equipment up and running. If your home relies on a sump pump, well pump, or other equipment that uses a lot of power to start up, youll need to install a battery that is specifically intended for backup power.
If you install a conventional generator, you wont have to worry about critical loads. As long as you choose a generator that is sized properly by your installer, you should be able to keep your home or business running without issue, assuming you have adequate fuel onsite.

If you live somewhere with extreme weather or regular power outages, it’s a good idea to have a backup power source for your home — particularly during hurricane season. There are various types of backup power systems on the market, but each serves the same primary purpose: keeping your lights and appliances on when the power goes out.
In the past, fuel-powered standby generators have dominated the backup power supply market, but reports of risk of carbon monoxide poisoning have led many to search for alternatives. Battery backups have emerged as a more eco-friendly and potentially safer option to conventional generators.
Despite performing the same function, battery backups and generators are different devices. Each one has a particular set of advantages and disadvantages, which we’ll cover in the following comparison guide. Keep reading to find out about the main differences between battery backups and generators and decide which option is right for you.

Ial Home Backup: How It Works
Partial home backup only powers essential household appliances. Bigger appliances will automatically turn off during an outage, because only the essential loads subpanel receives power from the backup system.
A partial backup system can be sized based on the essential appliances you need to power. That means the system size can be much smaller.
When it comes to wiring, the circuit breakers for your essential appliances need to be relocated into a subpanel, which is powered by the backup system during an outage.
Is Battery Storage Right For You
Battery storage can provide you additional control over powering your home, allowing you to keep essential devices powered during outages. Due to PG& Es need to mitigate wildfire risk through Public Safety Power Shutoff events, customers may experience outages more frequently.

What Is A Whole Home Battery Backup
Whole home battery backup means having access to all of your home’s circuits so that you can decide which appliances to power in a grid outage. Those decisions can be based on many factors including lifestyle needs, time of year, solar production, battery size, and battery charge state.
Sounds simple, but energy transmission is a complex process and is highly regulated for safety. When power enters a home via the main electrical panel, it passes through circuits which manage the current flowing to our appliances, phones, computers, and anything else we use that consumes energy. Introducing a battery into the mix, that is capable of picking up where the grid leaves off so that everything from your freezer to your Wi-Fi continues to run smoothly, is no small feat.
In this whiteboard video, we illustrate a couple of backup scenarios for the average home which consumes about 30kWh per day. When actually quantifying how much power you really need during an outage, it becomes clear for most homeowners that whole home battery backup may not be necessary. An alternative strategy, made possible by Lumin’s technology that allows for flexible energy management, is to configure a system with partial backup. In this scenario, homeowners have more choice when it comes to making backup decisions. Battery backup for home appliances, for example, is a good place to begin an audit of your energy needs.
