Understanding Battery Capacity, Power, and Lifespan for Solar Applications
When you're shopping for a battery, you'll see terms like "capacity," "power," and "lifespan" thrown around. Let's break them down:
- Capacity (kWh): This is how much energy the battery can store. A higher capacity means you can power more appliances for longer.
- Power (kW): This is how much power the battery can deliver at any given moment. A higher power rating means you can run more high-demand appliances simultaneously.
- Lifespan (cycles or years): This is how long the battery is expected to last before it starts losing its ability to hold a charge. Most batteries are warrantied for a certain number of cycles (a full charge and discharge) or a certain number of years.
Think about your energy needs and choose a battery that has the right capacity, power, and lifespan for your situation.
