"Frank and his team did a fantastic job upgrading our electrical panel and wiring for our generator. He even came out to help us during off hours when we needed help with starting the generator! He is quick to get back and does above and beyond. I highly recommend and will use his company again and again!"

"I cannot stress enough how impressed I am with their commitment to customers. After the installation of an outlet for an EV charger and an upgrade to my panel, I had a minor issue. Within an hour of me reaching out to inform them of the issue, I received a call with an offer from Endrite to come by later in the day to take a look. The repair was done at my convenience with no additional charge. They were thorough and went beyond what was probably needed to ensure the problem did not re occur."

"Greg the owner of Papa Grieves is an amazing, incredibly honest and dependable pool expert. He came to my house on Friday to repair my propane heater. The heater needed 2 parts and Greg only had 1 of the required parts on his truck. He called me, explained what needed to be done and that he would come back on Saturday to finish the job. Greg said that although the heater had a great deal of rust, he could fix it so that it would work for the remainder of the season. He did NOT try to see me a new heater, but I asked him what a new heater would cost. The price he quoted me was 20% less than what my current pool company, that did not return my call about my heater not working gave me at the beginning of the season. I asked him if he could install the new heater on Saturday, because I was having a big party on Sunday and he said the heater was in stock and that he could do the job the next day. Saturday morning the rain was coming down in buckets and I did not expect Greg to show up. But to my shock and amazement, at 10 AM the Papa Grieves Pool truck pulled into my driveway. In the pouring rain Greg and his assistant Raul removed the old heater and installed the new one. They performed all of this work without asking for a deposit or credit card for security. The heater works great. PARTY SAVED!!!!! That you Papa Grieves!!!!!"

Generator Install questions, answered by experts

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
