10 Things You Need to Know Before Getting Home Battery Storage Installed

As energy prices rise and concerns about sustainability grow, more homeowners are turning to battery storage as a smart way to take control of their energy use. Whether you’ve already invested in solar panels or you’re looking to make the most of off-peak tariffs, a home battery system can be a powerful tool to reduce your energy bills and increase energy independence.
At MAC Renewables, we’ve installed hundreds of these systems across the Midlands. But before you dive in, there are a few key things you should know. Here’s our top 10 list—based on real-life installations, hands-on experience, and plenty of hard-earned lessons.
1. Know Your “Why”
Are you looking to store excess solar energy, reduce reliance on the grid, use cheaper off-peak energy, or gain backup power in case of an outage? Your motivation will help define the right system for your home.
2. Solar or No Solar?
Already have solar panels? We’ll need to know how big your system is and how much excess energy you typically export. That’s the energy you could be storing for nighttime use. No solar? No problem. You can still benefit by charging your battery using cheaper overnight tariffs.
3. Get Your Smart Meter Ready
Smart meters are essential for unlocking the full benefits of a battery storage system. Without one, it’s difficult to track, control, and optimize your energy use effectively.
4. Wall Space is Prime Real Estate
Battery systems, especially wall-mounted ones, need room. A neat 2m wide by 2.5m high space can be ideal for installation and future maintenance. Good ventilation and clearance from flammable materials are also important.
5. Compatibility with EV Chargers
If you own or plan to buy an electric vehicle, make sure your battery and charger are compatible. A mismatch can lead to your EV draining your home battery unintentionally.
6. AC or DC Coupling?
Most retrofit installations use AC-coupled batteries, but if you’re adding solar and batteries together, a DC-coupled system could be more efficient. We’ll help you choose the right configuration based on your goals.
7. Backup Power Options
Some systems, like the Tesla Powerwall, offer whole-house backup power. Others, such as MyEnergi Libbi, offer essential circuit backup only. If you’re in an area prone to outages, that backup capability might be a game-changer.
8. Internet Connectivity is Essential
Whether it’s Wi-Fi or hard-wired Ethernet, battery systems rely on a stable internet connection for monitoring, software updates, and participating in smart grid schemes.
9. Smart Tariffs & Grid Interaction
With tariffs like Octopus Flux and platforms like GiveEnergy’s “GiveBack” scheme, you can earn money by discharging to the grid during peak times. It’s a smart way to reduce your bills—and support the energy network during demand surges.
10. Planning for the Future
Whether it’s an EV charger, heat pump, or future extension, we always recommend installing a consumer unit with room to grow. We’ve seen too many homes with a tangle of mismatched units added over time. Future-proof your home from day one.
Real Installations, Real Insights
We’ve fitted a range of systems—from SolaX with full backup to GiveEnergy All-in-One systems in detached garages, and Libbi modular setups that integrate beautifully with existing MyEnergi ecosystems. Each system has its strengths, and our job is to match the right one to your home, lifestyle, and energy goals.
Thinking of putting your battery in the loft? Think again—weight, fire safety, and accessibility all make it a less-than-ideal location. We’ll guide you through smarter alternatives that are safe, practical, and scalable.
Next Steps
Before we quote, we’ll ask for a few key details:
- Your electricity usage (smart meter data helps!)
- Existing solar setup (if any)
- Preferred battery location (with photos)
- Main fuse size and consumer unit details
To make this process easier, call us our team of experts to guide you through the process and book a site survey.
