Home batteries, backup power & generators

“I want backup power at home, but I don't know what to buy.”

Battery, generator or both? Understand your options before investing thousands.

Storms and outages make backup power tempting – and easy to oversell. We help you figure out what you actually need to keep running, for how long, and at what cost.

Common situations

Hurricane season is coming and you want to be prepared.
You were offered several batteries but don't know if you need them all.
You're torn between a standby generator and a battery system.
Proven in practice

Hands-on experience with a complete home system with 7 Tesla Powerwall 2 batteries and live energy monitoring.

What we check and explain

What must keep running

Whole home or essential loads only – fridge, Wi-Fi, lights, A/C, well pump?

Capacity vs. power

kWh (how long) and kW (how much at once) – the two numbers most people mix up.

Battery vs. generator

Fuel, noise, maintenance, runtime in long outages and total cost of ownership.

Charging from solar

How batteries refill during a multi-day outage, and what happens on cloudy days.

Warranty and lifetime

Years, cycles and energy throughput – and what “guaranteed capacity” really means.

Red flags

  • More batteries than your usage and goals justify.
  • Vague promises like “runs your whole house for days”.
  • Whole-home backup sold when essential loads would do.
  • Financing that hides the real total cost.

Questions to ask the seller

  1. Which circuits will be backed up, and for how long at my typical usage?
  2. What is the usable capacity (kWh) and continuous power (kW)?
  3. Can the system start my A/C or well pump?
  4. What maintenance is needed and what does it cost?
  5. What is the total cost including installation, permits and financing?
