Battery Storage Systems

Power When You Need It Most.
Battery storage systems give you control over when and how you use your energy. By storing excess solar power or low-cost grid energy, you can keep your home or business running during outages, reduce peak utility costs, and increase energy independence. Elex Solutions designs and installs advanced battery systems that integrate seamlessly with your solar setup for reliable, around-the-clock power.

Take Control of Your Energy Future

At Elex Solutions Inc., we design and install advanced Battery Energy Storage Systems (BESS) that empower you to manage your power independently. Whether you need to protect your property from unexpected outages, reduce peak utility costs, or optimize your existing solar setup, our expert team delivers tailored storage solutions.

Energy storage is no longer optional—it is the backbone of a modern, resilient energy system. Our installations are engineered for long-term performance, safety, and seamless integration.

Our Battery Installation Services

We provide end-to-end solutions for both residential and commercial sectors.

  1. System Design & Engineering tailored to your needs and goals

We assess your specific energy load profile (usage patterns) to size a battery that meets your backup duration and budget goals.

  1. Residential & Commercial ESS Installations
  • Residential: Sleek, wall-mounted or floor-standing units for whole-home or partial-home backup.
  • Commercial: Scalable, modular energy storage cabinets for industrial applications and load management.
  1. Retrofit & Solar Integration

Already have solar panels? You don’t need a new roof. We specialize in AC-coupled battery retrofits that seamlessly integrate storage without altering your current solar setup.

Why Invest in a Battery Energy Storage System?

Modern energy requires modern solutions. Here is how an ESS adds value to your property:

Backup Power When You Need It Most: Protect your home or operations during grid failures. A properly sized ESS acts as a generator replacement, keeping lights, Wi-Fi, refrigeration, and critical systems running instantly and silently.

Maximize Your Solar Investment: Don’t send your free solar energy back to the grid for pennies. Store excess daytime solar energy and use it at night or during peak utility hours to drastically reduce your electricity bill.

Reduce Peak Demand Charges: For commercial clients, demand spikes are often the most expensive part of the energy bill. Our systems utilize peak shaving to automatically discharge batteries during high-demand periods, lowering your costs.

Achieve Grid Independence: With smart controls and automation, you are less dependent on utility fluctuations.

Enhance Sustainability: Energy storage improves system efficiency by completing the microgrid structure at your home or business. It also reduces waste and increases the specific percentage of renewable energy you consume daily.

Our Preferred Equipment Providers
for Maximum Efficiency

We partner with leading manufacturers to offer top-of-the-line solar panels, inverters, and battery storage systems. The products we use are known for their durability, efficiency, and long-term reliability.

Elex Energy Storage System

Tesla Powerwall

The All-In-One Powerhouse
As a Certified Tesla Installer, we recommend the Powerwall for homeowners looking for maximum power density and sleek aesthetics.

  • Massive Capacity: With 13.5 kWh of usable energy per unit, a single Powerwall can back up most homes overnight.
  • High Power Output: The Powerwall 3 features an integrated solar inverter and can sustain high loads, allowing you to easily start up heavy appliances like air conditioners or well pumps during an outage.
  • Storm Watch: The intelligent software automatically detects incoming severe weather and charges your battery to 100% in preparation for potential grid failure.

Enphase IQ Battery

The Safest, Most Flexible Choice
For clients who value modularity and safety above all else, the Enphase IQ Battery (formerly Encharge) is the gold standard.

  • Modular Design: Available in 5 kWh increments, this system allows you to start small and expand later. You don’t have to buy more battery than you need.
  • No Single Point of Failure: Unlike traditional batteries, Enphase uses distributed architecture. Multiple microinverters inside the battery ensure that if one component has an issue, the rest of the system keeps running without interruption.
  • Safety First: Built with Lithium Iron Phosphate (LFP) chemistry, these batteries are cobalt-free and fire-resistant, making them one of the safest options for residential use.

SignStor by SigEnergy

The 5-in-1 Smart Energy Ecosystem

For homeowners who want the most advanced, future-proof technology available, we install the award-winning SigenStor.

  • True All-in-One Design: SigenStor replaces the clutter of separate boxes. It combines the Solar Inverter, Battery Inverter, Battery Pack, Energy Management System, and an optional DC Fast Charger for your Electric Vehicle—all in one sleek tower.
  • AI-Driven Optimization: Built with industry-first AI capabilities (GPT-4 enabled), the system automatically learns your usage habits and tracks weather forecasts to make smarter decisions about when to store, use, or sell your power.
  • Ultimate Scalability: Whether you need a small 5 kWh backup or a massive 48 kWh whole-home commercial-grade system, the modular battery blocks simply “click” together, allowing you to expand instantly as your family grows.

 

Which one is right for you? During our site assessment, we will help you find the perfect match according to your specific situation, such as your electrical panel, solar setup, and budget.

Fontana Construction is impressed with our first collaboration with Elex, and looking forward to the next several and beyond.

Alvin Leung

We had first asked them to help install a Tesla Wall Connector a couple years back they did such a phenomenal job from the initial planning, execution, and delivery. Elex Solutions has provided amazing service from start to finish. We were so pleased with the service and price that recently we had them come back to help upgrade our solar system to perform even better. They are the go to electrical company! Thank you!

Frequently Asked Questions (BESS)

How long will my battery last during an outage?
This depends on the battery capacity (kWh) and your electrical load. Most homeowners can power essential loads (lights, fridge, internet) for 8–24 hours on a single charge. If paired with solar, the battery can recharge during the day, potentially providing power indefinitely.
Do I need solar panels to install a battery?
No. Batteries can operate independently by charging from the grid. This is useful for backup power and avoiding Time-of-Use rates. However, pairing with solar provides the best financial return and energy security.
Is a battery system safe for indoor installation?
Yes. Modern LiFePO4 systems are extremely safe, featuring built-in thermal management and fire-resistant chemistry. They are designed to be installed in garages, basements, or utility rooms.
Can I expand my battery system later?
Yes. Most of the systems we install are modular. You can start with one battery module and add more as your energy needs increase (e.g., purchasing an Electric Vehicle).
Are there incentives available?
Yes. The Investment Tax Credit (ITC) and various local rebates often apply to energy storage. We will help you identify available incentives in your area.
