        What is Powerwall?

        Powerwall is a state of the art Tesla battery system for residential and light commercial applications that enables the storage of energy such as solar power. Commonly, Powerwall can be used to store solar energy during the day for use at night time. It can also provide backup power in case of a grid outage. Depending on where you live and the electricity rates in your area, Powerwall can potentially save you money by shifting energy consumption from high to low rate periods. Lastly, it can also help you take control of your energy and achieve self-sufficiency from the grid.

        BSLBATT Powerwall Technical Specs

        BSLBATT Powerwall’s is the replacement of tesla is one of the highest density residential and light commercial AC battery economical storage solutions on the market. Backed by the BSLBATT name, the Powerwall is a 13.5kWh capacity rechargeable lithium-ion battery that boasts 7kW peak and 5kW continuous power. Each Powerwall holds 12.2 kWh of usable capacity and maintains a 10% reserve so that when the power goes out, the battery has enough power to turn your solar on to get the battery recharged when the sun comes up the next day. This is enough to run a few lights, keep your freezer from defrosting, and power a few select appliances; can you say Game of Thrones binge when the power is out?!

        At roughly 650 mm tall, 480 mm wide, and 190 mm deep, the BSLBATT Powerwall’s compact profile combined with floor and wall mount options that can be installed inside or outdoors means you don’t have to sacrifice a ton of space for more storage.

        What does a BSLBATT Powerwall Battery do?

        Just like any other battery storage option, a BSLBATT Powerwall captures and holds the energy to be used by your home or business when needed later. What makes the Powerwall different from other battery storage options currently on the market is its capacity to support larger loads which means you have the freedom to power up more of what you need.

        By how much will BSLBATT Powerwall reduce my electricity bill?

        The savings that can be generated by using a BSLBATT Solar system with Powerwall depend on your location, the electricity rate in that area, whether you have solar, how you consume energy throughout the day and several other factors. Generally, however, Powerwall will benefit those who are not often home during the day as they can store energy during the day and use it during the evening.

        A BSLBATT Powerwall can be used to increase self-consumption of solar production, save money with time-of-use load shifting, store and provide back-up power, and can help you to reach off-grid goals with the ease of customizing how your stored energy will be used right from the app. 

        How does a Powerwall Battery Work?

        In basic terms, sunlight is captured by your solar panels then converted into energy that you can use for your home. As that energy flows into your house, it is used by your appliances and any excess energy is stored in the Powerwall. Once the Powerwall is fully charged, additional electricity your system generates on top of that is sent back to the grid. When the sun goes down and your solar panels are not producing energy, your Powerwall will provide electricity to power your home.

        Can you set Powerwall charging priorities?

        There are various consumption modes that set priorities for charging and consuming that you can program your Powerwall to from the app.

        Backup Only -- All the energy in your Powerwall is saved for those rainy days when you need emergency back-up power

        Self Powered  --  Power your home with energy stored from your solar system after the sun sets

        Balanced Time-Based Control -- Power your home when the sun goes down, and avoid expensive on-peak electricity rates by using electricity stored from your solar system

        Cost-Saving Time-Based Control -- Maximize your savings by using stored, low-cost, off-peak energy during expensive, on-peak hours

        Why should I choose a BSLBATT Powerwall battery?

        Powerwall is wall-mounted, attractive and comes with a warranty for up to 10 years. BSLBATT has chosen to supply Powerwall as part of our high-quality solar systems as we know it is one of the safest, best performing, and cost-effective products on the market. It is also extremely easy to maintain requiring no intervention once installed. Take control of your energy today.

        Do I need PV/Solar to operate Powerwall?

        No. Powerwall can be charged using AC power from the grid or a generator. BSLBATT also offers the BSLBATT Solar Charge Pack, which includes a home battery, inverter system, and solar PV which can be used for load shifting or backup power.

        Where can I install my Powerwall?

        BSLBATT Powerwall is suitable for both indoor and outdoor installation. Floor or wall-mounted options are available. Generally, Powerwall would be installed within the family garage area.

        What's the difference between single-phase and three-phase electricity?

        Electricity is either connected at 230 or 240 volts (single-phase, which accounts for the majority of domestic situations), or 400 and 415 Volts (three-phase). The latter is better suited for powerful appliances. A single-phase connection is common in small to medium-sized houses that use an average amount of electricity. Three-phase connections are more common in larger houses that utilize a lot of electricity, or in rural areas.

        How does single-phase and three-phase apply to home solar systems?

        You are able to purchase either a single-phase or three-phase inverter. Solar power systems installed on a three-phase property can have either a three-phase or a single-phase inverter – a single-phase inverter will deliver power to one phase (one circuit) only, while a three-phase inverter will deliver power equally to all three phases (three circuits).

        When is three-phase more appropriate?

        1. Big electric motors (usually more than 2 kilowatts) need three-phase power. This includes ducted air conditioning or large workshop equipment.

        2. Large domestic installations sometimes have three-phase because it distributes the total load in a way that ensures that the current in each phase is lower.

        How many Powerwalls do I need?

        We’re seriously not trying to dodge this question, but it really is different on a site-to-site basis and from a personal preference. For most systems, we install 2 or 3 power walls. The total number is a personal choice depending on how much power you want or need to store and what types of devices you hope to switch on during a grid outage. Each of our systems is fully customized to maximize the homeowner’s financial benefit and to reach their goals. To get a full picture of how many power walls you might need, we would need to have an in-depth conversation about your objectives and review your average consumption history.

        How long does a BSLBATT Powerwall battery last on one charge?

        It depends on what you use. Let’s just say you won’t be blasting your AC if the power goes off at night. A more realistic assumption for one Powerwall would be to run ten 100 watt light bulbs for 12 hours (without recharging the battery).

        How long does it take to charge a Powerwall with solar?

        This is another question that’s hard to quantify.  How long it takes to charge a Powerwall with solar really depends on the weather, brightness, shading, outside temperature. In perfect conditions with no loads and 7.6kW of solar power, a Powerwall could charge in 2 hours.

        Does a Powerwall automatically switch on when the grid fails?

        Your Powerwall will operate in a grid failure and your home will automatically switch over to the batteries. If the sun is shining when the grid goes down, your solar system will continue to charge your batteries and stop sending any energy back to the grid. We are required by code to install a “gateway” unit that relays power from your system to the Powerwall and isolates all the power in the house from the grid. This ensures the safety of lineworkers and is an automatic process when the grid goes out.

        Can I use a BSLBATT Powerwall to go off-grid?

        The short answer is potentially, but the big misunderstanding is what off-grid really means and how much it would cost. In a true off-grid scenario, your home would not be connected to a utility company’s electric grid. In North Carolina, it can be difficult to elect to disconnect from the grid once the property is already connected. You can terminate your service, but you would need a large enough solar system and an extensive amount of batteries to maintain the average family’s lifestyle. What size solar + battery set would come with a six-figure price tag. Along with the cost, you need to consider what your alternative energy source would be if you are unable to recharge your batteries from solar.

        Keep in mind, even if you are still connected to the grid, a solar + battery solution will significantly reduce your reliance on your utility (while also providing energy savings) without the added complication and cost of engineering a fully disconnected off-grid solution. At the end of the day, it’s possible to reach net-zero electricity use — or even be net-positive — without physically disconnecting from the grid, and it’s a lot easier on your wallet.

        On the flip side, in a new construction scenario in an undeveloped area, going solar with battery backup can amount to huge savings compared to what it might cost to have the utility run power to the site…depending on its location. If you’re already off-grid, a Powerwall is also a better solution than a lead-acid battery because of its capacity and longevity.


        How much does a BSLBATT Powerwall cost?

        Each Powerwall can run from $5000 to $12,500 depending on how many you purchase and if you purchase with solar. Don’t forget, now is the best time to go solar with battery storage since 2019 is the last year to capitalize on the full 30% Federal Tax Credit before it starts to fade away in 2020 and disappears in 2022. This incentive is also only eligible for batteries if they are connected to a solar system.
