Every solar battery also comes with a product warranty, which is usually 10 years. Not that you’ll ever use your battery in that way – instead, you’re likely to use about 50% and then charge it back up to 100%, which would count as half a cycle. Every battery comes with a guaranteed number of ‘cycles’, with one ‘cycle’ being one complete discharge and one complete recharge. When you’ve installed your solar battery, you’ll want it to last for the longest time possible. However, you can still find some great options that’ll shrink your break-even point below the typical 26.3 years for a solar-plus-storage setup. Getting a solar battery isn’t cheap, with even the smallest units costing more than £1,500. When shopping for a solar battery, you should always look out for the battery’s usable capacity and factor that into how much electricity your home needs. Only a handful of solar batteries have 100% usable capacity - most range between 90% and 95%. The usable capacity of a storage battery is not how much electricity it can store, but how much of a battery’s total capacity you can actually use.Ī battery’s capacity can be misleading, as you shouldn’t typically use a battery’s entire capacity, otherwise you run the risk of damaging it. We analysed the core attributes of all these batteries, then decided to focus on the seven most important factors: The usable capacity, value for money, warranty, range of features, size, operating temperature, and how well a battery worked during a power cut. Our team of four researchers spent 28 hours investigating the storage battery market to find the 27 best batteries currently available. How did we choose the best solar batteries? Want to know how solar batteries are installed? Go to our step by step guide. You’ll also get a beautifully designed app you can use to read how much power you’ve stored, how much electricity you’re currently consuming, and whether you’re using solar power or the grid to charge your battery. It’s designed to break connection with the grid immediately in these situations, so there’s no danger of power feeding back into the grid and putting engineers at potential risk. The Encharge works seamlessly in power outages too, with automatic grid-failure detection, which immediately turns on the battery during power cuts. It does this with its smart switch feature, which automatically switches between solar, grid, battery, or generator power, depending on what you need. The Encharge functions as an all-in-one solution for a home’s entire energy system, meaning it manages more than just solar panels. The Enphase Encharge 10T is at the cutting-edge of solar batteries, offering a plethora of features that places it firmly on top for impressive technology.
