"Gentleman who owns Solarize was professional and courteous. He communicated well with the manufacturer and convinced them that a replacement inverter was needed based on the data he saw and the manufacturer had seen. It's what we were hoping for."

"The problem turned out to be a burned out small electric door switch. I believe the price was way too expensive for the service performed and the price of the door switch. What more can I say? It got done."

Electrical questions, answered by experts

In the United States, home outlets support a standard 15 amps, but you can upgrade per outlet if necessary. Most single-family residential homes have a maximum overall amp rating, usually 100 to 200 amps. Very old houses may have less than 100 amps, but that’s rare. Large homes often come with amp services above 200 amps to support modern lifestyles.

You can make a pigtail with either thermoplastic high-heat-resistant nylon-coated (THHN) wire or non-metallic (NM) cable, often referred to as “Romex.” Each pigtail requires a neutral wire, a ground wire, and a live wire. The gauge of your pigtail wires must match the gauge of those on the device. 

In most cases, line wires are located at the bottom of a panel or device, while load wires are located at the top. Line wires are generally black, while load wires are typically red or black. To tell for sure, you can use a multimeter or volt pen to test the wire. A live or line wire will always carry a charge, while a load wire will only carry a charge when it’s in use.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

Hiring a professional electrician to wire a house costs anywhere from $1,500 to $10,000 or more depending on the size and complexity of the project. Most professional electricians charge $50 to $100 per hour. While the extra expense is significant, it’s worth it to ensure the safety of your home’s electrical system.
