Q: Can you use biofuel in a whole-house generator?

• <div><p>In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.</p></div>

Q: Can a portable generator power an entire home?

• <div><p>A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a <a href="https://www.angi.com/articles/installing-whole-house-generator.htm">whole-home generator</a> instead. </p></div>

Q: What is the life expectancy of a whole house generator?

• <div><p>With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.</p></div>

Q: Can I use a generator to charge a back-up battery?

• <div><p>Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.</p></div>

Q: How do I know what size of whole house generator to choose?

• <div><p>Generators are usually sized by running watts and starting watts. Ideally, you&rsquo;ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. <a href="https://www.angi.com/articles/electrical-load-calculation.htm">Calculate your home&rsquo;s electrical load</a> based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.</p></div>

"Great experience from start to finish! I would be happy to recommend his services to family and friends. Throughout the process he was punctual and communicative, I was always well informed what was happening. During installation of the panel he discovered a bad meter box that needed to be replaced, it was unavoidable. He was able to complete both repairs in a timely manor. Due to what work was performed a state inspection was required. it passed with no issues. For me, the whole experiences was great, I never felt pressured into any repairs that were out of the scope of what I was asking for. 5 stars from this guy!"
