![]() Since electricity usage is power multiplied by time, if you use more power, then you'll run out of stored electricity faster. Be sure to look for the usable capacity of a battery, as that number represents the amount of stored electricity that you can actually access in a battery. As a result, a battery's storage capacity tells you how long your battery can power parts of your home. While power is expressed in kW, battery size is expressed in kilowatt-hours (kWh), which is power multiplied by time. Battery size/usable storage capacityĪ battery's capacity (or size) is the amount of electricity it is able to store and supply to your home in the battery bank. This is important if you have an appliance like a sump pump that requires a large amount of power to turn on but then runs at lower power. Importantly, solar batteries often have two different power ratings–a continuous power rating and a 5-minute or instantaneous power rating–meaning they can provide more power in short bursts. Most of the batteries available on the market today have a continuous power output of around 5 kW. For instance, a typical compact fluorescent lightbulb will use 12 Watts (or 0.012 kW) of power, while a 3-ton AC unit will draw 20 Amps, which is equivalent to 4.8 kW. Power is expressed either in kilowatts (thousands of Watts) or in Amps, and different appliances use different amounts of power. In other words, a battery's power rating tells you both how many appliances your battery can power at once and which appliances those are. The power rating of a battery refers to the kilowatts (kW) of power that the battery can provide at once. If you want a battery with the absolute highest safety rating possible (don't worry, they're all safe!), look to LFP solar batteries If you want a battery with the longest lifetime that you can cycle the most amount of times, look for lithium iron phosphate (LFP) batteries ![]() If you are space constrained and want to get the most amount of storage out of the least amount of space, look for lithium-ion nickel manganese cobalt (NMC) solar batteries If you want to get the most out of every kilowatt-hour of electricity you put into your battery, look for batteries with a higher round trip efficiency If you want to run your home with your solar battery for a longer amount of time, look for types of batteries with a higher usable capacity If you want to be able to power a more energy-intensive appliance (like a sump pump), look for a battery with a high instantaneous power rating If you want to power more of your home at once, look for a solar battery with a high power rating ![]() Here are a few of the most common decision criteria, as well as which battery specs matter most if these criteria match your situation: There are a number of different potential decision criteria and comparison points to make when evaluating your stored energy options. ![]()
