Our Trusted Partners

At OSJ Electric, the quality of an electrical installation depends on the quality of the equipment behind it. We work with a select group of industry-leading manufacturers whose products meet the standards our Lafayette, California customers expect. Every brand we partner with has earned its place through proven reliability, strong warranties, and technology that holds up over the long term. When you hire us for an EV charger, a panel upgrade, or a solar project, you get equipment we trust and installation done right the first time.

Tesla

Tesla is best known for its Powerwall home battery and Wall Connector EV charger. The Powerwall stores energy from the grid or from a solar system and delivers backup power when the utility goes down. The Wall Connector is a fast, wall-mounted Level 2 charger built for daily home charging. We install and configure both, and we set up Tesla systems to work together so your solar, battery, and vehicle charging run as one connected setup.

Emporia

Emporia builds smart home energy products that make electricity use easier to see and control. Their Level 2 EV charger delivers fast charging at a lower price point, with load management that keeps your panel from being overloaded. The Emporia Vue energy monitor tracks usage circuit by circuit, so you know exactly where your power goes. We install Emporia chargers and monitors for homeowners who want smart features without a premium price.

SolarEdge

SolarEdge is a leader in solar inverter technology. Their systems use power optimizers on each panel, which means shade or a single underperforming panel does not drag down the whole array. SolarEdge also offers home batteries and EV charging that tie into the same platform. We design and install SolarEdge systems built to produce more energy over their lifetime and to give you clear monitoring of every panel.

Enphase

Enphase pioneered microinverter technology, which places a small inverter on every panel rather than running the entire system through one central unit. That design improves safety, boosts production, and keeps the system running even if one panel has an issue. Enphase also makes the IQ Battery for storage and EV chargers for daily use. We install Enphase solar, battery, and charging systems for homeowners who want panel-level performance and reliability.

General Motors

General Motors has moved well beyond vehicles into home energy through its GM Energy line. These products include home EV chargers and bidirectional charging that can send power from a compatible GM electric vehicle back into your home during an outage. We install and set up GM Energy equipment so your vehicle and home work together, turning your EV into a backup power source when you need it.

Span

Span makes a smart electrical panel that replaces the traditional breaker box. The Span Panel gives you app-based control over every circuit, real-time energy monitoring, and smart backup management that decides which circuits stay powered during an outage. It pairs naturally with solar and battery systems. For panel upgrades, Span is one of the most capable options available, and we install it for homeowners who want full visibility and control over their electrical system.

EcoFlow

EcoFlow builds portable and whole-home backup power solutions. Their systems range from portable power stations for smaller needs to whole-home battery setups that keep your household running through extended outages. Many EcoFlow products pair with solar for off-grid and backup charging. We install EcoFlow backup systems for customers who want dependable power protection without a complex permanent installation.

Why Our Partnerships Matter to You

A partnership is only worth mentioning if it benefits the person paying for the work. Here is what ours mean for you.


  • Certified installation that protects your warranty. Manufacturers back their products fully only when the work is done to their standards. We install to those standards, which keeps your warranty intact and your equipment covered for the long term.


  • Systems that actually work together. Solar, batteries, EV charging, and smart panels perform best when they are chosen to be compatible from the start. Because we work across all these brands, we design your setup as one connected system rather than a set of parts that happen to share a house.


  • The right product for your project, not a one-size-fits-all answer. No single brand is best for every job. Working with a range of manufacturers lets us match the equipment to your home, your budget, and your goals instead of forcing a fixed catalog on every customer.


  • Access to current technology. The home energy space moves fast. Our partnerships keep us current on the latest chargers, inverters, batteries, and smart panels, so you get proven equipment rather than yesterday's models.


  • One point of contact for the whole job. You deal directly with us from the first conversation through the finished install. We handle the equipment, the setup, and the questions, so you get consistent, one-on-one communication from start to finish.


With 20 years of experience serving Lafayette, California and the surrounding area within a 20-mile radius, we bring the right equipment and the right people to every project. If you are planning an EV charger, a panel upgrade, a solar installation, or a backup power system, we would be glad to walk you through the options and recommend the partner products that fit your home.
