Introduction

Backup power generation has become increasingly critical for homes that rely heavily on sensitive electronics, medical equipment, refrigerated medications, and other essential appliances.

Power outages can disrupt lives and put health and safety at risk. As technology becomes even more integral to how we live and work, portable backup generators have evolved to provide more power, longer run times, and enhanced features - and they continue to improve rapidly.

In 2023, there are more options than ever before to ensure your critical loads stay powered when the grid goes down. For those wanting the latest and greatest in home backup power for 2023 and beyond, this guide explores the options, highlights key factors to consider, and recommends some of the best portable generators to keep your sensitive home electronics, appliances, health equipment and other essential items running even during extended outages. Reliable home backup power is now within easy reach.

What is a home backup generator?

A home backup generator is a device that provides alternative electrical power to a home during a power outage. It helps ensure critical loads remain powered even when the main electrical grid is down. Know more from our blog.

Key benefits of home backup generators

Provides emergency power for critical circuits - Keeps essential items running like lights, appliances, medical equipment, sump pumps, refrigerators, etc.
Peace of mind - Ensures you have power even during major outages for things that significantly impact daily life or health/safety.
Protects sensitive electronics - Prevents damage or loss of sensitive equipment, tools or appliances that could suffer power surges or spikes.
Allows you to shelter in place - Gives you the option to stay home rather than evacuating during some outages if power is only expected to be out for a short time.
May be required for medical needs - Some people rely on equipment like CPAP machines, oxygen concentrators, refrigerated medications or other life-sustaining power sources during an outage. A home backup generator provides this backup power.

How does home backup generator work?

Home backup generators operate in essentially the same three stages as standard power supply chains, but have some key differences:

Solar generation - Uses photovoltaic solar panels to generate direct current (DC) electricity from sunlight during the day. At night or in poor weather, solar generation stops and the system relies on stored battery power.
Energy storage - Large lithium-ion batteries store the DC power generated from the solar panels during the day to use at night or during an outage. The more battery capacity, the longer the run time.
Inversion and power output - An inverter converts the stored DC power to alternating current (AC) that is used to power loads or supplement grid power at typical home voltage levels (120/240 volts).

Important considerations when buying home backup generators

Power output (wattage) - Determine how many watts of power you need to power your essential loads. More wattage means more power but at a higher cost and size/weight. Typical ranges are 500W to 3000W for home use and smaller generators.
Battery capacity (watt-hours) - The battery size will determine how long your system can power loads when not charging. Larger capacities like 800-3000Wh provide 12+ hours of run time but cost more and weigh more. Find the right balance for your needs.
Solar panel capacity (watts) - The solar panels recharge the batteries during use. Larger solar panel arrays will recharge the batteries faster but again cost more. Panel sizes range from 150 to 600W typically for home backup generators.
Number of AC outlets - Consider how many outlets you will need to power all of your essential loads simultaneously. Most have 3 to 6 outlets but some larger systems provide 20 outlets or more.
Voltage options - Many home backup generators output 120V and 240V power. Choose the voltage that matches the power inputs for your specific equipment. Dual voltage systems provide more flexibility.
Maximum surge power - The surge wattage or "peak power" refers to the maximum amount of power that can be briefly drawn from the system before the voltage starts to drop. Higher surge power means compressors, motors and other high-draw loads can start without issue. Important for appliances like refrigerators, sump pumps, etc.
Types of power - Only some home backup generators provide modified sine wave power, which is compatible with sensitive electronics. True sine wave inverters provide higher-quality power but at a higher cost. Choose the wave type that suits your specific loads.
Additional features - Consider things like max AC input for charging abilities, inbuilt Solar Charge Controllers, USB ports, cargo straps for secure transport, cooling fans, cargo cover, etc. depending on your needs.
Cost - Home backup generators range from $500 up to $3000 or more for higher power systems with larger battery capacities. Determine your maximum budget to find alternatives that suit your needs and funds.
Weight and size - More powerful systems, larger batteries and larger solar panels will result in heavier and larger units. Ensure you have means to transport and set up whatever system you choose. Compactness is one benefit of portability.
