![]() Here are the SunVault’s technical details: When the SunVault debuted in 2021, SunPower envisioned it as a rival to the Powerwall, with many of the same features and a comparable power profile. The Hub+ acts as the “brains” of the system, with the battery usually mounted next to it on the wall. This system comes in two parts, the SunVault Battery and the Hub+. These add-ons take up space, limiting your ability to work them into a workable design scheme while leaving you fewer options for concealment. Also, the Powerwall requires multiple electric boxes and additional parts to meet local electrical codes. Depending on when you order one from Tesla, it could take months before your Powerwall arrives. Its lower price has created a waitlist for the Powerwall. ![]() Also, the Powerwall is one of the least expensive solar battery options on the market. Multiple Powerwalls can be stacked together to boost storage capacity and power more appliances throughout your home or business. It sports a sleek design and mounts nicely to the wall. The Powerwall has become the biggest name in solar batteries since launching in 2015. Power: 7kW peak / 5kW continuous seamless backup transition pure sine wave output.Energy Capacity: 13.5 kWh, can be combined together with up to 10 Powerwalls.Here are the Powerwall’s technical details: There’s no exposed vents that expel heat or visible wires making it a safer solution for households with kids or pets. It utilizes a lithium-ion battery that runs much quieter and cleaner than a conventional gasoline back-up generator. Tesla has designed this AC battery system for residential and light commercial use. Also, both feature simple-to-use apps that allow you monitor your home energy system in real time and make changes to the way they dispense power throughout the day. The two batteries are designed to use primarily for emergency backup. Both are AC-coupled, which makes both easier to install into an existing solar panel system. These two different batteries share a lot in common. Let’s take a look at each battery and see how they stack up to each other. This allows your solar panels or battery to operate as a code-compliant off-grid electrical system until the utility company can turn your power back on.Īnother big selling point for solar batteries is the 30% federal solar tax credit, which you can apply towards the final price. AC-coupled batteries like the Powerwall and SunVault automatically disconnect your system from the grid when the power cuts out and use the solar panel system or battery bank to power your critical loads. This is a safety mechanism that will allow the utility company’s workers to repair the lines during an outage without fear of being electrocuted. Because your solar panel system is wired into your electric company’s grid, they will stop producing energy if the power goes out for any reason. It’s important to note that in most installations without a battery your home will not be able to utilize the electricity generated from your solar panels when the grid goes down. They also can power your home when the power grid goes down. That stored energy can power your home when your solar panels aren’t generating energy, including nights and cloudy days. To put it simply, they store excess electricity generated by solar panels. Which battery makes the most sense for your situation? In this article, we’ll rundown the differences between both batteries, including pricing, capabilities, availability and styling.įirst let’s start with the basics of solar batteries. ![]() ![]() Here at Good Energy Solutions, we mainly install two different brands of solar batteries, the Tesla Powerwall and SunPower’s SunVault. One of the most common questions we are asked is “Should I install a battery with my solar panel system?” With rising concerns over power grid outages during extreme weather events, energy storage has become a more important piece of the solar puzzle. ![]()
