20 years as a licensed electrician before going solar myself in 2019. Made every mistake in the book. Now I help homeowners size systems correctly and avoid costly mistakes — no installer referral fees, no skin in the game.

How long will a 20 kWh battery power a house?

I’ve been a licensed electrician for 20 years, and the short answer is this: a 20 kWh battery will usually power a house for about 10 to 20 hours, but the real number depends almost entirely on what you keep running. If you run only the essentials, it can stretch close to a full day […]

What is the tax credit for home battery storage?

I’ve told a lot of homeowners the same thing lately: if you are asking about the federal tax credit for home battery storage in 2026, the useful answer is that the old 30% credit mattered only if your battery was fully installed by December 31, 2025, and for a brand-new install now, you should assume

How do home batteries work?

I have wired enough backup systems to tell you this upfront: home batteries are useful, but they are not magic, and I would only buy one if your outage risk, utility rate structure, or backup priorities justify the price. If you are trying to decide whether a battery belongs in your house, focus on what

How much does a whole-house battery backup system cost?

I?ve priced a lot of backup setups, and for most homes a real whole-house battery system lands somewhere between $12,000 and $35,000 installed, with larger or more capable systems pushing past that fast. My blunt take is this: the battery itself is only part of the bill, and the expensive mistake is buying too little

How much load do you need from my battery backup system?

I tell homeowners this all the time: my first job with a battery backup system is not chasing the biggest number on the brochure, it is figuring out what loads you actually need the system to carry when the grid drops. If you only need the essentials, a smaller battery setup can make good financial

How did we choose these home battery backup systems?

I have picked apart enough battery backup setups to tell you this upfront: I do not choose them by brand hype or app screenshots, I choose them by what they will actually keep running when the grid drops and whether the cost makes sense for a real house. A flashy battery with weak surge output,

What is the Largest Power Bank on Planes?

I’d keep this simple: the largest power bank I would even consider bringing on a plane is one that stays at or under 100 watt-hours, because that is the line where airline-friendly turns into hassle fast. In real life, that means a normal laptop-class power bank is usually fine in your carry-on, but a true

Where Should I Pack My Power Bank When Flying?

I pack my own power bank in my carry-on every time, and I would not put it in a checked bag unless I wanted to risk a problem at security or at the gate. If you are flying with a phone charger, a laptop battery pack, or a small backup battery for travel, what matters

Can You Charge Your Phone on a Plane?

I’d keep this simple: yes, you can usually charge your phone on a plane, but I would never count on the seat USB port as my only plan, and I definitely would not buy a big portable power station thinking it will solve air-travel charging. If you are trying to decide what to carry for

Can I charge my electric vehicle for free?

I get this question a lot as an electrician and a solar owner: yes, you can sometimes charge an electric vehicle for free, but usually only in specific situations. In the real world, ?free? EV charging usually means workplace charging, promotional public charging, or using solar power that you?ve already paid to install on your

What is the cheapest way to charge an electric car?

I tell homeowners this all the time: the cheapest way to charge an electric car is usually at home overnight on the lowest utility rate you can get, and if you already have solar, the next-best play is charging in the middle of a sunny day instead of chasing expensive gear you may not need.
