The Generark Solar Generator is a fantastic option for households looking for a cost-effective, eco-friendly, and portable generator that still packs a punch and can hold a lot of emergency power for use in a lengthy power outage, or during trips away from mains electricity.

This product contains both the Generark HomePower ONE and SolarPower ONE (the battery unit and the compatible all-weather solar panels). The two units can be used together for the ultimate solar-powered generator.

It’s designed to be used in just about any household and is therefore compatible with a wide range of essential devices, as well as being super user-friendly. Let’s see what features this generator has to offer!


Seeing as the Generark Solar Generator comes with two individual units – the power station, and the additional solar panel – it’s helpful to go through the key features of each unit separately, although they come as a whole kit and are totally compatible.

The Generark HomePower ONE generator is the unit that provides emergency backup power. Once fully charged, this unit can last for up to seven days powering crucial household devices on one single charge: that’s right, up to a whole week!

This includes smartphones, laptops, fridge freezers, lights, and other home appliances. It’s worth noting that it has a capacity of 1,002 kWh, which means very high wattage devices won’t work with this generator.

You can find the full list of devices the Generark HomePower One is compatible with on Generark’s website.

For full compatibility, this unit includes 3 AC outlets that use a pure sine wave, which results in an even power voltage supply (so there are no sudden electricity spikes). It also has 4 USB ports, including one surge power socket for super-quick device charging if needed.

A really handy affordance of this generator is the ability to charge multiple devices at once. In households, arguments over who gets to charge their devices are incredibly common.

This feature helps to keep the kids amicable, and what’s more, you can use kitchen appliances whilst your devices charge. Great for a tension-free home (or even camping trip)!

Close Up of the HomePower One

Although this unit can be fully powered by the provided solar panel, a key feature is the option to also charge it via AC power in your house or to charge it through your car. This can be useful when the sun isn’t shining, or during a storm. It uses vehicle-grade battery cells, which means that it’s fully compatible with power from your car.

Once your backup generator is fully charged, it will hold its battery for up to one year! So, if you have an annual charge-up, you can rest assured that you’ll be equipped with enough power to deal with power outages throughout the year. You can also re-charge this unit while you’re using it, so you never have to go without power.

When it comes to safety considerations, the Generark Solar Generator has some pretty nifty safety systems built into its power unit. There’s an in-built industry-leading battery management system, which includes overcharge protection, short circuit protection, over-discharge protection, over-current protection, voltage protection, and temperature control.

Other nifty features of the Generark Solar Generator include a handy LCD display which lets you know how much power outage is being used (in wattage), as well as the remaining battery capacity. Generark also has a useful usage time estimator on its website. It’s also pretty portable, as it has a comfy, padded foldable handle which is useful for carrying it around.

The other part of the Generark Solar Generator Kit is the SolarPower ONE solar panel. Although you can buy the two parts separately, this solar panel is a great addition to the Generark Solar Generator as it enables a free, eco-friendly, and readily available power supply for your generator.

This unit is powered by monocrystalline solar cells, which, in simple terms, means that it offers a 50% greater energy conversion than traditional solar panels, which is great. The panel can also be used to quickly charge a small electronic device such as a mobile phone directly from the panels, as it emits 100W of direct voltage.

This panel can bring the Generark Solar battery unit up to full charge in 8-hours, providing it is placed in direct sunlight. The panel is also really portable and comes with a kick-stand, which allows it to be angled for optimal sun absorption, and can be set up in less than 30 seconds (trust us, we tested it)!

It will have you set up with backup power for your crucial devices within minutes, should your power fail, and it is really easy to charge up too. When you need to use it, here’s what you need to do:

  1. Before using the generator on a trip, or when your power fails, you need to make sure it’s fully charged. Preparation is key! Should you have any severe weather warnings, it’s a good time to ensure the battery is full.
  2. To charge the unit, you have three options: to use the solar attachment provided, plug it into your mains power, or charge it through your car.
  3. We would recommend, wherever possible, using the solar attachment: it’s eco-friendly and totally free! To use the panels, carry them along with the generator to a sunny, non-shady outdoor space. Use the kickstand to stand the panels on the ground. Then, attach the generator to the panels with the provided cord.
  4. Leave them there for around 8 hours to get a full charge: it might take slightly longer on a less sunny day!
  5. Once your generator is fully charged, you can take it back into the house and start using it (or place it in storage until it’s needed).
  6. To use the generator with your electronic devices, simply plug them directly into the unit via the AC outlets or USB ports. They’ll have power instantly!
  7. The LED screen will let you know how much wattage is currently being used (the max is 1000wH), and how much charge your backup power generator has left.

What Does a Solar Generator Do?

A solar generator is a battery power station that works alongside solar paneling in order to provide essential power back-up to a home when the mains electricity is out or to charge devices whilst on the go and away from AC electric supply.

In scientific terms, solar generators work to convert heat and energy conducted from the sun into DC electricity. This type of electricity passes through the charge controller (a key component of a solar generator) and converted to chemical energy for storage in the battery. When you want to use that power for your home appliance, the inverter will turn it into usable AC power.

The key difference between a solar generator and an ordinary generator is that they are usually portable systems that use large panels to conduct energy from the sun, rather than charging the unit from the mains electricity. The generator uses solar panels and photovoltaic energy to harness the heat from the sun and turn it into usable emergency power.

It can be useful to see a step-by-step breakdown of how a solar generator provides power:

  1. The solar panels convert sunlight into DC (direct current) energy
  2. This is then passed through the charge controller: this component regulates the voltage of the energy, so it can be stored in the battery for later use
  3. When you plug a device into the generator, the inverter will convert the DC energy stored in the battery into alternating current energy (AC), which is what most household appliances and devices use and run on. This is what makes the generator compatible with everything in your household!

For these reasons, solar generators are lifesavers during black-out situations, as they’re not reliant on mains power for charging, and can provide power to almost all household devices (including medical devices) easily and efficiently. They’re also super cheap to run, eco-friendly, and last a long time, which is a win-win.

Are Solar Generators Worth My Money?

Backup generators offer a fantastic emergency power backup for the house, as well as the option of having portable power for outdoor situations such as road trips or camping holidays.

Significantly, however, solar generators provide a way of harnessing free, eco-friendly energy from the sun to power your unit, which is why they’re so great.

Solar paneling has a long lifespan or around 25-30 years, so you can save a lot of money on energy over time. They’re not cheap, but they are a great investment for those who want the peace of mind of a backup power unit or regularly need portable power and want to harness eco-friendly, sustainable, and cheap energy.

What Is The Most Powerful Solar Generator?

One of the most powerful solar generators on the market is the Generark Solar Generator. This model is the ultimate machine for those who want to be prepared for disasters: it has a very high energy capacity of 1,000 Wh and has almost double the battery storage of other similarly priced units.

When considering technical specifications, this generator is one of the biggest and most powerful.

What Is The Best Solar Generator For My Home?

The best solar generator for your home will depend on what you plan on using it for most often.

For example, if you want a solar generator to provide power whilst out and about, you might want to opt for a smaller, more portable option such as the Renogy Phoenix 200, which is very lightweight and compact so is great for active situations. It can only charge low-power devices, however, such as phones and laptops, so isn’t good as a home generator.

However, if you’re looking for a great overall generator, which could be used to power your home and retains some portability, we really would recommend the Generark Solar Generator. It’s portable AND powerful, so offers a great middle-ground for most households.

When Would I Need A Backup Battery Power Station?

The main reason why most households keep a backup battery power station is in case of power blackouts, caused by things such as freak weather so that you always have access to emergency electricity for your home.

You may also want to take a backup generator with you on trips where you won’t be near mains electricity for long periods of time, such as on camping, boating, or campervan trips. Portable solar generators can be really useful in these situations.
