Renogy Phoenix Portable Solar Generator, All-in-one kit

View Product on Amazon

For extreme emergency situations. Has two 20w monocrystalline solar panels built into a compact briefcase-like portable device. It can be charged with either solar, an AC wall socket or a car port. It comes with a 16Ah Li-ion battery. Charges at approximately 0 and 45C. It has a maximum continous outage of 150 watts, so if you have a device less than that, you should be able to power it with this phoenix. One user noticed that you get an additional 1% charge every ten minutes, so its quite slow to charge.

Since this is an emergency generator for extreme situations, you’ll find that most user reviews are from those who bought them for earth quake contigencies, it’s adviced that you take it out of storage and charge it under the sun at least twice a year, so that it’s ready for use when you need it.

Features To Consider Before Buying Solar Generators

1. How Much Power Will You Consume?

You’ll either be using your solar powered generator as a home backup or for remote camping and travelling adventures. The average home in the US uses about 1100 watts per hour. So you’ll want to get backup solar generators that can at least power critical appliances during blackouts. You’ll need something within the 800 to 1100 watts range. Camp adventures require way less power, so you don’t need to spend too much on a generator that will be under used.

Note that even though some solar generators can promise more than 1100 watts per hour, it’s your responsibility to know how long your appliances will be powered before the battery runs out. Actually, the battery capacity will depend both on how much power you consume per day, and whether the battery can be charged while it’s being used.

2. Energy sources

Generally, the smaller the solar generator, the less installation needed to get it to a fully functional mode. However, some solar generators come with expandable panels. If you’ll be going somewhere remote, or don’t experience power outages often, it’s much better to use a portable generator.

That said, some generators combine solar powered systems with electric powered inverters or even gas or diesel powered systems. Because even though no one person has a claim to the sun, it can be difficult to recharge solar generators during heavy winters, when power outages are common and sunlight can go days without showing up.

3. Time Before Next Recharge

Given a set of panels, how long will it take a solar generator to fully recharge? Solar generators with expandable panels option will typically charge faster. You’ll also need to know if you can charge the battery while it is being used.

4. Type Of Solar Panel

The material used, poly crystalline, thin film, or mono crystalline, will determine the energy conversion rate (how fast it goes from being sunlight to power).

Mono crystalline panels are the best, as they have the highest conversion rates (above 20%) while poly crystalline panels come in at a close second.


Beware of hidden charging and battery limits. All generators, that is their electrical circuitry, are constructed differently. So the amount of power that can be delivered continuosly and at peak demand will be limited by its internal components (quality of circuit breakers, fuses, inverter) and the plug’s amperage limit. So make sure you read any, and all special instructions before buying.

Having seen the most relevant features to take into consideration, you should be just about ready to buy.

Wrapping It UP

Alright, there you have it. You’ve seen some of the best solar generators in the market. And even though these generators aren’t as powerful as their gas-powered counter-parts, they do serve the backup and off-grid purpose typical generators offer.

This is aside from the added benefit of using renewable resources, so less carbon footprint, not to mention it generates less noise and it’s way cheaper than gas-powered generators. As long as power outage is expected be short-lived, solar generators are the best direction to go.
