Home Energy Storage: A Guide for New Users

What is a Home Energy Storage System

A home energy storage system is essentially a device that captures electricity for later utilization. It functions as a giant "power bank” for your home and is commonly paired with solar panels. The solar panels generate electricity during the day. Extra power gets stored. During overcast periods or overnight, the stored electricity can power your home. 

LiFePo4 batteries are commonly used in home energy storage systems. They are safe and have a long lifespan. Small batteries can store 300Wh, which can charge phones and small devices. Other batteries can store up to 10kWh or 30kWh.

Why Home Energy Storage is Worth Considering

Batteries are lifesavers during outages. In the event of a blackout, stored energy can power lights, run refrigerators, and charge phones. That level of comfort can be priceless.

Secondly, it reduces electricity expenses. When you store solar energy during the day and use it at night, you lessen your dependency during peak hours when grid electricity is costlier. Through this strategy, the cumulative savings are substantial.  

Additionally, it benefits the environment. Stored solar power reduces the reliance on fossil fuels and thus, carbon emissions. Many systems operate quietly. Therefore, there is no disruption during daily activities at home, and portable models are convenient for outdoor events like camping or backyard gatherings.  

What to Look for When Choosing a Home Energy Storage System  

Evaluate the power needs for your household first. Consider what devices you have to power, like only lights and phones, or air conditioners and washing machines as well. That determines how much capacity you need in Wh or kWh. A small home might make do with 5kWh, while a larger one could need 10kWh or more.  

Battery type matters a lot. A good option is LiFePo4 batteries since they are long-lasting. Many can endure more than 6000 charge-discharge cycles. So, they do not need to be replaced for many years.

For this specific system, safety is a must. Assess whether the system incorporates an efficient BMS (Battery Management System). This technology safeguards the battery against overcharging, over-discharging, short circuiting, and overheating/ overcooling. Also, certifications like CE, UL, and ROHS are a plus, as they show the product complies with safety regulations. 

Does the system have the ability to expand? Can you add more battery packs when your power requirements increase? Many systems have this feature which is a plus for a growing family or increasing power consumption needs. Also, the ability to modify the systems is a plus—a handful of providers are willing to tailor the systems to the customer's particular space or behavioral needs. 

Warranty shouldn’t be neglected. Quality systems tend to offer a 10-year warranty, which shows the manufacturer stands behind their product. 

Tips for Using Home Energy Storage

Keep an eye on the system’s temperature. Batteries perform at their best when they are kept at moderate and stable temperatures. Very cold or hot temperatures can impact battery performance, and therefore placing the system in a well ventilated room, away from sunlight as well as cold drafts would be ideal.

Proper charging and discharging of the battery. Avoid letting the battery completely drain or charging it all the way to 100%. Doing this will wear out the battery faster. While most systems have built-in protections, charging and discharging the battery within 20%-80% daily will prolong the battery's lifespan.Add

Maximize the use of free power by using solar. If solar panels are already in place, ensure that the system is configured to trap as much solar energy as possible during the day, this will help maximize the use of clean, free power.

Incase multiple systems are needed, like one for home and one for outdoor use, reach out to the supplier and ask for bulk order discounts. Many suppliers have discounts for bulk orders which can greatly help in cutting costs.
