Back-up Vs. Non Back-up
Learn about the differences of back-up and non back-up batteries
Back-up Vs. Non-Back-up Storage Options
When it comes to selecting the right battery storage option for your home, there are two main choices to consider: back-up batteries and non-back-up batteries.
Back-up Batteries
Back-up batteries, as the name suggests, provide power to the home even if the grid power goes out. These batteries are designed to store excess energy produced by solar panels during the day and make it available during times of low or no sunlight, such as at night or during power outages.
The advantage of backup batteries is that they offer a reliable source of electricity during blackouts. This can be particularly beneficial for homeowners who live in areas with frequent power outages or those who prioritize having an uninterrupted power supply for critical appliances or medical equipment.
Back Up Battery Options:
Non-Back-up Batteries
On the other hand, a non-back-up battery is a storage option that will not supply power to the home during grid outages. These batteries are primarily used to store excess energy generated by solar panels and discharge it back to the grid at times when buyback rates with your local utility are the highest.
Non-back-up batteries are typically more cost-effective compared to back-up batteries since they do not require the additional capacity to supply power during outages. They are suitable for homeowners who are primarily interested in reducing their electricity bills by maximizing the self-consumption of solar energy.
Non-Back Up Battery Options:
Partial Home Back-up vs Whole Home Back-up
When selecting a backup battery option, the number of batteries compared to your normal energy usage will determine if your home has partial energy backup or whole home energy backup capabilities.
Partial home backup means your battery storage system will only support a limited number of electrical loads or appliances in the event of a power outage.
Whole home backup means that your battery storage system is capable of supplying power to the entire home during grid outages. Keep in mind that even with whole home backup, if you use an excessive amount of electricity, you can still run the risk of draining your battery before it has the opportunity to charge again. For this reason, we discourage the use of high electrical demand activities such as running the air conditioner or charging an electric vehicle when the power is out.

Choosing the Right Option
When deciding between back-up and non-back-up solar storage options, you should consider your specific needs and priorities:
- If an uninterrupted power supply during outages is important, investing in a backup battery system is recommended.
- If the goal is primarily to reduce electricity costs and maximize self-consumption, a non-back-up battery system can be a more economical choice.
- Factors such as the frequency of power outages, availability of alternative power sources, and budget should also be taken into account.
Ultimately, both options offer advantages and contribute to a sustainable and resilient energy system.
