The ClearPOWER P2 Home Backup Battery System Explained

A sudden power outage in today’s fast-paced world can be more than just a nuisance. It can affect your livelihood. Your kids might start to panic, you won’t be able to charge your phone, or the food in your fridge might go bad. Also, no Wi-Fi. So, how do you keep your home running smoothly without power? Unless you have some alternative power supply, you’ll be sitting in the dark for hours. Luckily, there is a solution — portable home backup batteries. They are affordable, practical, and will keep the lights on until you get back on the power grid. One such product is the ClearPOWER P2 home backup battery system.

What is the ClearPOWER P2 home backup battery?

ClearPOWER P2 is a battery system that can power your home for a few hours after a power outage. It has two parts — the battery and the docking station. The battery works by integrating into your circuit breaker panel. You can connect at most three circuits and loop them through the battery. That means you would have to determine in advance what parts of your home you want the battery to power. In most cases, you’ll want to power only essential appliances until your home gets back on the grid.

The average power outage in the US lasts for about 112 minutes. So, a backup battery with a few hours of juice will be more than enough. But, that will depend on the number of appliances you connect to the battery.

What appliances can you connect to the battery?

To get the most out of the ClearPOWER P2 battery, there are a couple of things you should consider. First, you should power only the appliances that you need the most. The essentials can be the lights, refrigerator, your computer, TV, or Wi-Fi router.

But know that various appliances consume different amounts of electrical power. For example, at an average of 200 watts per hour, this battery can power your fridge for about seven hours. Similarly, at an average of 100 watts per hour, your TV will have power for about 15 hours.

On the other hand, there are appliances that you should think twice about powering with this battery. For example, you shouldn’t connect water heaters, dryers, or air conditioners. If you must, be sure to check if the appliance exceeds the capacity of the battery. In general, a single appliance shouldn’t exceed 15 amps. So, choose the three circuits you want to loop through the battery wisely.

Installation process

ClearPOWER P2 is a portable battery system that’s easy to use and install. It’s an all-in-one energy solution in case the power goes out. But, you will need to hire a licensed electrician to install it for you. Even though this is a true “plug-and-play” type of battery solution, remember that you’re still dealing with live electrical wires which can be dangerous if you don’t know what you are doing.

The installation manual calls for two critical steps for the battery to function properly. First, you have to identify the three critical circuits that you want to have powered in case of an outage. For example, if you want your fridge to have power, you would need to figure out which circuit controls the outlet the fridge is plugged into.

Once you’ve done that, you will have to cut the power to the circuit panel breakers. After that, you can start the installation process. You connect the docking station to the circuit breakers, not the battery itself. The docking station is designed to support three 15-amp circuits.

Obviously, this was a simplified illustration of how easy it is to install the ClearPOWER P2 battery system. In reality, the process is more complex and requires skills and professional tools to complete safely. So, once again, you shouldn’t attempt to install the battery system yourself if you are not a licensed electrician.

Automatic Power Outage Detection

The ClearPOWER P2 battery system comes with a feature that automatically detects when the power goes out. In that situation, the Auto Transfer Switch will sense that there is no power coming from the grid and instantly route electrical power to the three circuits you have chosen.

So, you’ll never be caught off guard and your essential appliances will have power until you get back on the grid. In reality, you don’t even need to be at home at the time of the power outage. The battery will kick in straight away. People who have smart homes could benefit from the automatic activation feature the most. If you connect your Internet router to the backup battery, you’ll be able to manage your smart home remotely without power.


Since ClearPOWER P2 is a battery, it needs a power supply to charge itself. The automated charging process will take care of that for you. There are two ways to charge the battery. First, you can set it to charge via the grid. The battery will automatically pull in power from the circuits while in charging mode. Second, you can connect the battery to your solar panels and let it charge that way. Since the charging process is automatic, you can rest assured that your ClearPOWER P2 battery system will always be fully charged when a power outage occurs. Just keep in mind that you’ll need to make regular maintenance checks to ensure that the battery continues to function properly.
