Best Backup Batteries for Home and Off-Grid Living

Solar energy systems are ideal for Kiwis who want to make the most of their off-grid lifestyle. Of course, to optimise your solar energy usage, you need to equip your system with the right components - such as backup batteries. 


What Are Backup Solar Batteries? How They Work And Why You Need Them


Solar batteries work just like normal batteries - they store energy that you can tap into later. They’re an absolute must-have for solar energy systems because, chances are, you’re not going to use every bit of energy that your solar panels absorb during the day. Rather than letting that green energy go to waste, you can use it at a later time.


  • During The Day: Your solar systems’ panels will generate electricity as they usually do. If there’s excess energy that you don’t need at the moment, that power will be stored in your solar backup batteries.

  • At Night Or During Power Outages: If you cannot use power from your solar panels, you can tap into your storage to keep your home lit.

  • During Peak Hours: Some systems let you use battery power if your solar panels aren’t generating enough energy, even if the sun is out. 


Batteries mean your solar system will be more efficient, cost-effective and reliable.


  • Enhanced Energy Independence. Use your own green energy generated by your solar system, rather than relying on the grid. The energy grid may be unreliable for rural locations. 

  • Reduced Electricity Bills. When you use less energy from the grid, you’ll pay less in energy bills. You’ll gradually make back the money you invested in your solar system. 

  • Improved Sustainability. Reduce your impact and meet your environmental goals by investing in clean, green, renewable energy. Utilise all of the energy you generate, not just the energy you use in the moment. 

  • Access To Backup Power. We all know how frustrating power outages can be. Solar backup batteries are an extra energy source, keeping your lights on even when the grid is unreliable. Power outages can occur due to harsh weather, grid failures or maintenance, but you don’t have to deal with them if you have solar batteries.

  • Peace Of Mind. You most likely have essential appliances in your home that you’d like to keep on, like a freezer that safely stores food. In a power outage, your food safety could be compromised, potentially leading to spoilage and food waste. A backup system provides you with peace of mind. Even if the grid fails, your appliances will remain functional. 

  • Enhanced Value. The presence of solar batteries can increase the value of your solar system and your property as a whole. Plus, they can save money by not letting energy go to waste. 


Top Qualities To Consider When Purchasing Backup Batteries


Just like when you’re choosing your solar system, it’s vital that you look at the right qualities when picking out your solar batteries. It’s best to work with your solar technicians when making your decision, as they can guide you through your options. 


Storage Capacity And Usage Needs. You should choose batteries that suit your home’s energy needs. Work with your solar technicians to assess your storage needs so you can pick appropriate battery capacities.


Qualities like the size of your home, the number of people in your family and your usual energy demands will help determine the kind of batteries you should choose. 


Compatibility With Your Solar System. You must choose batteries that can work with your solar system. Look at the specific kind of system you have with your solar technician, and then narrow down your battery options to products that can work well with your system. 


Longevity. Talk to your solar power expert about the projected lifespan of your selected batteries, and ask about any warranties. 


Installation Costs. Ask your solar electrician about how they will install the batteries. How much will the installation cost? How long will the process take? What kind of changes will be made to your system? 


Maintenance Requirements. How will you maintain your solar backup batteries? You must take care of every part of your solar system so that it stays efficient and lasts for a long time. Along with maintenance tasks that you can do yourself, ask them about professional inspection, repair or maintenance services that they may offer. 


Control Features. How will you be able to monitor and control your batteries? What kind of capabilities do the batteries have? Ask about smart device monitoring to check your current energy stores and alter your system's use.
