BATTERIES

 Selecting the right home battery energy storage system depends on your energy needs, budget, and future plans. Lithium-ion batteries are great if you want a compact and highly efficient solution, while lead-acid batteries are ideal if you’re looking for an affordable backup option. 

 Battery capacity refers to the maximum amount of electricity a unit can store when fully charged. 

Think of this as the size of a water tank (total volume of energy stored). 

 This measures how much electricity the battery can deliver at once. It determines how many appliances you can run simultaneously.  If your portable power station can’t supply enough starting watts, your appliance won’t turn on.

 Think of this as the width of the pipe (how fast water flows in or out). 

  Peak power in batteries is the maximum electrical power a system can deliver for a very short, specific duration (seconds or few minutes), significantly exceeding its continuous, sustainable output. It is critical for managing high-demand spikes, such as starting electric motors, or compressors.

If you have a 1500 W dishwasher and 3000 W air conditioner. You need about 4.5 kilowatts (kW) of electricity from a storage system for the hour you run your dishwasher, and 3 kW of electricity the rest of the time.  If you have a battery with 9 KWh of Capacity, the system will run for 

9KWh/4.5KW = 2 hours.

• Ensure they are balanced to the same state of charge (SOC). 
• For a simple setup with just two batteries, connect them in parallel using a diagonal connection. 
• When connecting more than two batteries in parallel, using a battery busbar is always the best way.
• All batteries used are of the same type and the same age.
