4 Best Solar Generators for Power Blackouts in 2023


When a power blackout hits, what do you do? Go about your daily routine as usual? Of course not. 

Power outages force us to be proactive. There’s no telling when the power will come back on, so we have to make intelligent choices. This includes opening the refrigerator ONLY when needed to keep your food from spoiling. 

Another wise decision is to keep your personal electronic devices charged. You don’t have power for an undetermined amount of time, so you should keep your devices alive for as long as possible by only using them for emergencies. 

The best way to tackle a power blackout is to prepare for one. Outages all across Canada happen with increasing frequency, regardless of where you live. Homeowners need to be well-equipped for emergency power outages.

One of the best ways to do so is to invest in a high-end solar generator. These helpful devices keep necessary appliances running and reduce panic when the lights go out. 

Which solar generator should you invest in, and how do you choose? 

Here are the 4 top picks for power blackouts in 2022, followed by tips to guide your decision. 

4 Best Solar Generators for Power Blackouts

The EcoFlow DELTA collection was designed specifically with home backup and off-grid living solutions in mind. With reliability at the forefront of its design, you can expect powerful generators to keep your home running when the power goes out. 

Which one is best for your home? The right choice depends on several factors, like running watts, watt-hours, recharge time, and battery life. We’ll go into depth on these later in this article.

We’ve vetted each of the following generators with the above in mind to help you narrow down the shopping decision. Here are our four best solar generators for power blackouts. 

1. DELTA Mini

About the EcoFlow Smart Home Panel

We mentioned that homeowners can integrate the DELTA Pro with home circuits. This is possible thanks to the EcoFlow DELTA Pro ecosystem, which integrates up to two DELTA Pro generators with ten home circuits. Users will receive uninterrupted power during power outage emergencies, smart energy management, and lower energy bills.

To use, you’ll need to pair the EcoFlow Smart Home Panel with the DELTA Pro solar generator. Then, when the lights go out, the generator will switch on in seconds. To be exact, 20 milliseconds! It’s so fast that you won’t even know a power outage has hit. 

How it works is that this smart system immediately senses when a blackout strikes and then reroutes its energy to the DELTA Pro generator(s). When the power is restored, it will connect back to home utility lines before turning itself off to conserve energy. Many homeowners use this to lower energy bills and deploy the DELTA Pro ecosystem as a robust backup for power outages.

The EcoFlow DELTA Pro ecosystem is packed with power and stores this energy day and night. Not only will this lower your home’s energy bill, but it will also reduce your reliance on the grid. The nice thing about EcoFlow solar generators is you can use them while they harness the power of the sun and recharge simultaneously. 

Then, using the EcoFlow app, you can monitor the system, update preferences, receive a breakdown of your energy habits, and much more.

How to Choose a Suitable Solar Generator for Power Blackouts

With so many great picks, you’re probably wondering which solar generator is right for you. You need to ensure you get a solar generator that offers the power you need. 

Here are the criteria you need to consider before making a final decision.

Running Watts

Running watts, also known as rated watts, indicates the electricity the solar generator is capable of producing continuously. Think about the number of appliances you’ll need to power when an outage occurs. What’s the wattage requirement for each of these appliances? Add this up and ensure the solar generator’s running wattage is greater than this.


Next up is watt-hours (Wh), which measure the generator’s capacity. The watt-hours help ensure the power station can power the necessary appliances for the desired length of time. 

For example, the DELTA Mini has a capacity of 882 Wh. The capacity is equivalent to powering a 120W refrigerator for 5.4 hours. The DELTA Pro, on the other hand, has a capacity of 3600 Wh, which can power a 120W refrigerator for 24 hours.

Watt-hours tell you how much continuous power the solar generator can provide for 60 minutes with a full battery charge. It will also help you estimate the amount of energy the power station can deliver before it needs a recharge. For example, an 882 Wh generator like the DELTA Mini can power a 10-watt light for around 80 hours (DC) or 30 (AC) before the battery is exhausted.

Recharge Time

When it’s time to recharge the battery, how long will it take until power is restored? The recharge time gives users an idea of how long the solar generator will take to reach a full charge. The nice thing about EcoFlow solar generators is you can pair them with the EcoFlow app to monitor energy levels. It will let you know how much battery life is left until a recharge is needed.

Regarding recharging times, you need a power station that will charge quickly through solar panels or wall outlets. Keep in mind that cloudy weather will impact the charging speed when it comes to solar charging. Direct sunlight is best for the most rapid results. 

Battery Type

There are two main types of battery types that solar generators use: lead-acid or lithium-ion (Li-ion). 

Lead batteries are usually less expensive, but Li-ion batteries typically last longer. They also tend to be lighter — a top priority for portable applications.

EcoFlow solar generators use lithium-ion batteries, which offer the following benefits: 

  • Safe-to-use
  • Lightweight
  • Offers constant power
  • Charges quickly
  • Temperature tolerant
