When catastrophe strikes and power grids go down, being prepared as a homeowner is essential. This is especially true during rolling blackouts, a phenomenon that has become more prevalent in recent years.

Unplanned power outages can last for hours, days or even weeks, disrupting critical services and uncomfortable living conditions if you're not ready. Having a backup power source at home provides security, stability and peace of mind during emergencies by ensuring continuous access to essential utilities. A home backup system is life-saving preparation that every home should have.

Whether through generators, solar panels with battery storage, battery systems alone, or a combination of multiple solutions, a home backup power secures electricity for lighting, heating, cooling, refrigeration, appliances, medical devices, communications and more even when the main power grid fails. Proper backup power coverage gives you confidence that the comfort and safety of your home and family will remain during unforeseen disasters or crises.

Home Power Backup

Types of home power backup systems

There are several options for home power backup systems. The most common types are portable generators, solar+battery systems, and smaller battery-based solutions. Generators provide power by running internal combustion engines that generate electricity on-demand during an outage. Solar+battery systems use solar panels to convert sunlight into stored battery power that is ready even when the grid is down. Battery systems offer emergency backup power for limited periods but require less maintenance.

Each type of system has its benefits.

  • Generators provide the most power for extended periods but require fuel, maintenance, and can be noisy.
  • Solar+battery systems are eco-friendly, long-lasting, and low-cost over time but have higher upfront costs and Battery capacities.
  • Battery systems are affordable and portable but typically only supply backup power for a few hours.

For comprehensive coverage, some homes install dual systems using both solar+batteries and a generator.

When an outage strikes, an automatic transfer switch helps automatically switch your home's circuits over to the backup power source. This allows for seamless operation of critical loads like refrigerators, lights, medical devices, and electronics during an emergency. The ideal solution depends on your specific needs, technical skills, and budget. With the various options available today, you can choose a backup power system that provides the reliability and sustainability you require.

What appliances and devices should I prioritize for backup power during emergencies?

Some key appliances and devices you should prioritize powering during emergencies include:

  • Lighting: Backup lighting provides safety, security and the ability to operate in your home during a blackout. Focus on emergency lighting, flashlights, headlamps, lanterns, etc.
  • Refrigeration: A backup power source will keep food fresh and prevent spoilage. Power your refrigerator, freezer, and any food storage areas.
  • Water system: Backup electricity ensures access to running water for hygiene, sanitation, cleaning, cooking and more. Power well pumps, pressure systems, holding tanks, plumbing fixtures, etc.
  • Space heating: Backup heat prevents damage from freezing pipes, maintains livable temperatures, and provides safety. Power furnaces, space heaters, wood stoves, pellet stoves, etc.
  • Medical equipment: Power any life-sustaining medical devices, oxygen equipment, refrigerated medicines, heating pads, suction machines or other gear as needed.
  • Cooktop: At least one backup cooktop or generator will allow you to prepare food, boil water, cook meals, get warm, etc. Connect a gas, propane or camp stove.
  • Communications: Backup power helps charge mobile phones, portable batteries, battery-powered radios, TVs, computers, modems, routers, smart speakers, etc. Access to communication is critical during a crisis.
  • Tools: A backup source provides power for emergency tools like generators, flashlights, radios, first aid kits, emergency blankets, batteries, a battery-powered radio, demolition equipment, fire extinguishers, etc. Proper tools gain importance if there are widespread outages or damage.
  • Alarm systems: backup sets ensure continued monitoring of security, medical, environmental or fire alarms. Connect or install an uninterrupted power supply (UPS) to protect alarm control panels, security systems and any monitoring equipment.
  • Entertainment: For long-term outages, some means of entertainment such as books, board games, puzzles, cards, streaming devices to access content, portable TVs, radios, portable phone chargers, recreational equipment, solar lanterns, etc. can improve morale.
  • Security systems: Cameras, lighting, alarms, locks, and monitoring rely on electricity. Backup power secures continued system function to monitor for intrusions, damages or emergencies even when the grid is down. Connect security system control panels to backup electricity whenever possible.

Choosing the right home power backup system

To choose a home power backup system that suits your needs, start by determining how much power you require and how much you can afford to spend. Estimate the wattage or amperage of essential circuits to run during an outage like lights, appliances, medical equipment, electronics, etc. Set a maximum budget for the total cost of purchase, installation, and long-term maintenance.

Compare the pros and cons of different backup system types like generators, solar panels with battery storage, battery systems alone, or dual systems. Generators may provide the most power but at greater cost, noise, fumes, and maintenance. Solar and battery systems are eco-friendly and low-cost in the long run but higher upfront investments. Choose between portability, whole-house coverage, or partial backup based on your priorities.

Once you evaluate and narrow down your options, do further research on specific brands, models, and products that could meet your needs. Compare features like capacity, runtime, output power, charge rate, portability, protection, safety, warranty, and review and rating information from other customers. Find the sweet spot of power, performance, ease of use, and affordability for the right balance of all your key factors.

Check if any government rebates, grants or smart energy programs can help lower the overall cost. Consider professional installation for more complex systems to ensure it is set up properly and safely meets all electrical codes. Be sure you understand how to properly operate and maintain whatever backup solution you choose if DIY installation or use is planned.

Buying a home backup power system is an important decision, so take your time evaluating options and finding the solution that provides you the security and peace of mind you need affordably while also matching the specific requirements and values that are most important to you. With the right system in place, you'll have greater confidence in any emergency. The effort you put into choosing a high-quality, comprehensive backup solution for your whole-house or partial critical backup power needs will be worth it for years to come.

Installation and maintenance of home power backup systems

The installation and setup process will vary depending on the type of home power backup system you choose. But Growatt solar products can be easily installed. Portable generators typically require little installation but you need to ensure proper ventilation, grounding, and safety when in operation.

Solar panel systems require installation of the panels, mounting hardware, inverter, and battery bank for energy storage. Battery systems necessitate installation of batteries, an inverter or charge controller, ventilation, and connecting the system to your main electrical panel.

Installation and maintenance of home power backup systems

After installation, consistent maintenance is important to keep your backup power system in good working condition and maximizing efficiency and lifespan. Tasks include but are not limited to:

  • Regularly exercising and recharging batteries according to manufacturer recommendations. This helps prevent the loss of battery capacity over time.
  • Inspecting and replacing air filters in generators and other engine-powered equipment. Clogged filters reduce efficiency and can damage components.
  • Checking fluid levels in generators and other engine-powered equipment and refilling as needed. Low or improper fluid levels can damage the system.
  • Inspecting solar panels and mounting hardware periodically and after severe weather events for any damage. Loose or corroded connections reduce performance.
  • Testing the entire system, including automatic transfer switches, under load at least once a year or as recommended. This ensures all components are working properly together before an actual power outage.
  • Having equipment serviced by a certified technician as recommended by the manufacturer. Many manufacturers require annual or semi-annual service for warranty coverage.
  • Storing equipment properly when not in use. Portable equipment should be kept in a garage or shed, out of weather and temperature extremes.
  • Don't forget the solar panel kits!

How can a home power backup system help me save money in the long run?

Are you wondering how a home power backup system can benefit you and save you money in the long run? A home power backup system can help save money in several ways:
