Before you choose a battery for your battery back up take a look at our comparison of battery technologies for your home and business
Choosing the right battery is a crucial step in designing a safe and reliable primary or back-up power source for your home or small business. Previously, I wrote about the different types of batteries available on the market for power systems. Now we are going to discuss how you can determine the type of battery and the size of system that will best suit your needs. Below are a few guidelines that will help you decide:
- Determine what you want to back up and for how long (how many hours or days of autonomy you require). This will help ensure you get the right size of system for your needs. For example, backing up a refrigerator, a few electronics, and specific lights in your home for 10 hours requires significantly less power than if you want to store enough energy to power your entire home for two days.
- How much maintenance can you commit to? Lead Acid batteries need to be taken care of regularly. We compare this to having another pet because there is a strict and time-consuming protocol to follow in order to properly care for Lead Acid batteries. They will also need to be replaced more often than Lithium Ion or Sodium Ion batteries.
- What is your price point? It is rarely advertised (and therefore often overlooked) that in most larger systems the batteries are ONLY ONE PART of the system. You still need to install a load center, charge controller, inverter, and an automatic transfer switch (ATS) in addition to your solar panels. These other expenses can be triple the amount of the cost of the batteries.
- Cycle Life is also a critical consideration. This determines the number of discharge/charge cycles the battery can provide before it degrades in efficiency and eventually needs to be replaced.
Of course, when you invest in battery system, you want to make sure it is installed properly from the very start. Choose a certified installer who has first-hand experience installing batteries and back-up systems.
