How To Choose A Residential Battery Energy Storage System

As energy costs climb and power outages become more common, many American homeowners are turning to residential battery energy storage systems (RESS) to lower bills and keep the lights on.

Whether you're dealing with rolling blackouts, storm-related outages, or simply want to take control of your energy expenses, these systems can completely change how you power your home.

In this guide, we'll break down how to choose a reliable energy storage system and explain why the MeterHome collection stands out as a smart solution.

Why Homeowners Are Investing in Residential Energy Storage

American homeowners are opting for residential energy storage systems for several reasons:

• High energy bills: In 2023, the average US household spent around $1,600 annually on electricity, although prices vary by state. Residential energy storage systems allow homeowners to store solar energy and use it during peak hours, significantly lowering energy costs.

• Frequent power outages: Research shows that power outages have increased by 20% since 2019, with the East and West coasts, Great Lakes, and Gulf regions facing the highest risk of weather-induced blackouts. A battery storage system ensures your household appliances keep running when the grid is offline.

• Energy independence/sustainability: By generating and storing their own surplus energy, homeowners rely less on the grid and fossil fuels. Investing in a home energy storage system also lowers their carbon footprint and contributes positively to broader environmental goals.

• Wasted solar resource: For homes with solar panels, excess energy/electricity generated during the day is often wasted or sold to utility companies via net metering programs. With storage, you can use the stored renewable energy, maximizing your solar investment's return on investment (ROI).

Now that you see why these systems are gaining popularity, let’s go over the steps to choose one that fits your home.

7 Considerations When Choosing a Residential Battery Energy Storage System

Here are seven key factors to consider when choosing a home energy storage system in the US:

1. Assess your energy needs

Choosing the right residential energy storage system begins with understanding your household's energy consumption, which is measured in kilowatt hours (kWh). To do this, check your utility bills to determine your average daily energy usage patterns. Most homeowners consume around 25-30 kWh daily, or roughly 899 kWh per month.

From there, you can decide if you want to go fully off-grid or need backup power (partial power) during outages. This helps determine the ideal battery capacity and power output system suited to your needs.

• Battery capacity: This is the total amount of energy a battery can store, generally ranging from 5-20 kWh for residential systems. A 10 kWh home battery storage system can power most essential household appliances (fridge, lights, Wi-Fi, etc.) for 10-12 hours during an outage.

• Power output: This determines the number of appliances you can run simultaneously and is measured in kilowatts (kW). A 5 kW power output is typically sufficient for most household needs, but using large appliances, such as HVAC systems, may require a higher output system.

Whole-home backup power usually requires a larger energy storage capacity (15-20 kWh) and higher power output. In contrast, partial backup systems (5-10 kWh) are often enough to keep essentials like lights, Wi-Fi, and fridges running.

If you live in an area prone to frequent/prolonged power outages, consider pairing your battery system with home standby generators for worry-free backup.

2. Understand battery technology

Not all battery systems are equal. Knowing the differences can help you pick the right residential energy storage solution for your home, budget, and goals.

• Lithium iron phosphate (LiFePO₄) batteries: Currently, the most popular choice for home energy storage systems. They're eco-friendly, safe, long-lasting (up to 8,000 cycles), and perform consistently for years.

• Lithium-ion batteries: These compact, high-energy batteries are still widely used due to their power density and efficiency. However, these more traditional options have a shorter lifespan than LiFePO₄ options.

• Lead-acid batteries: The budget-friendly but "old school" option. They're cheaper upfront, but heavier, less efficient, and need more upkeep. While they don't last as long as lithium-ion batteries, they can work for homeowners who want the lowest initial cost.

MeterHome's 14.3 kWh LiFePO₄ residential battery energy storage system gives you safe, reliable, and state-of-the-art home power, helping you lower energy costs while supporting a cleaner, greener future for your family.

3. Consider grid type and scalability

When choosing a residential energy storage system, you’ll need to decide how it connects to the grid:

• On-grid systems: These tie into your home’s solar panels and the national grid, enabling net metering and backup support from the utility. They help lower your carbon footprint while ensuring a steady power supply.

• Off-grid systems: These run independently, making them ideal for remote locations or areas with frequent grid outages.

It’s also worth considering scalability. Some systems allow you to add more battery units later, giving you flexibility as your household’s energy needs grow.

MeterHome’s Whole Home Battery Backup System with solar integration offers the best of both worlds. Designed as a hybrid solution, it works on-grid, off-grid, or anywhere in between. It stores clean, renewable energy from your solar panels, utility grid, or even a generator, delivering reliable power exactly when you need it most. Add up to 8 battery enclosures and 9 inverters for 114.4 kW peak power.

4. Evaluate battery system lifespan and warranty

Battery longevity ranks among the most important purchase considerations. Several factors affect this, including battery cell quality, whether the system includes a smart Battery Management System (BMS) to prevent damage, and how frequently the battery charges and discharges, called Depth of Discharge (DoD).

• Lifespan: Every battery has a limit to how many times it can be charged and used (called cycles). Lithium-ion batteries typically let you use around 80-90% of their capacity, while LiFePO₄ batteries can safely use up to 95-100%. Using more than the recommended limit (DoD) shortens the life of the battery. For example, if you have a 10 kWh battery and only use 8 kWh (80%) each time, it will last much longer than draining it completely every day.

• Warranty: Look for at least a 10-year warranty, and make sure you know exactly what’s covered; not just the years, but the performance level guaranteed.

MeterHome’s hybrid energy storage systems are built for long-term reliability, backed by a 10-year warranty and $1 million in liability insurance for the first three years. Our batteries can run for more than 8,000 cycles and are designed to hold 70% of their original capacity after 10 years. That means even a decade down the line, you’ll still have dependable backup power for your home.

5. Installation considerations

When installing a residential energy storage system, location and environmental conditions matter significantly. The battery system needs a temperature-controlled spot away from direct sunlight, such as garage walls, utility rooms, or basements.

MeterHome's energy storage systems are designed for reliable indoor use and include:

• IP44 protection rating: Protection against dust and splashes of water.

• Humidity resistance: Can handle levels up to 95%.

• Temperature range: Withstands charging temperatures of 32-95°F.
