Who It’s For

For someone who wants to be completely energy independent, there’s no better option than the EcoFlow DELTA Pro paired with our 400W solar panels. You’ll never have to worry about hooking up your power tools to a standard electrical outlet again — you’ll get all the power you need for your power tools (and more) from the energy you generate through the sun’s rays.

Add-Ons

For professionals or contractors who use high-capacity power tools day in and day out on the job, you may benefit from several add-ons for your solar generator and panel system. Delta Smart Generators and Smart Batteries can help keep your energy supply running for the long haul.

Delta Smart Generators 

The Smart Generator integrates with your DELTA Pro or Max model. It’s the perfect added backup for blackouts or off-grid situations where sunlight is unavailable. It runs on gasoline like typical generators and can quickly and seamlessly power devices like power tools if your solar energy runs out. 

Delta Smart Batteries

Choose Smart Batteries for your Delta MAX or Delta PRO solar generator. They can effectively double the generator’s total capacity to last longer and power more tools simultaneously. 

If you’ll be working long days on construction sites, having a smart battery compatible with your DELTA solar generator can keep you working without on-grid power sources.

The beauty of these add-ons is the interoperability with the EcoFlow solar ecosystem. You can combine these solar batteries and the Smart Generator to double, triple, or quadruple your power. 

What to Look for When Buying Solar Generators for Power Tools

Solar generators are an ideal way to get extra power when you need it. They convert sunlight into electricity, which you can then use to power your devices or appliances — in this case, your power tools. And unlike traditional generators, solar generators don’t require any fossil fuel. All you need is the sun!

So, how do you choose the right solar generator for your needs? There are a few things you’ll want to consider: capacity, life cycles, output and input, size, and weight. Let’s take a closer look at each of these factors:

Capacity

The capacity of a solar generator measured in watt-hours (Wh) is the amount of power the generator can store. If you have a lot of devices to power, or if you need to power them for a long time, you’ll want a generator with a higher capacity. 

A lower capacity isn’t necessarily a bad thing, though. If you’re only using a fraction of the capacity of your solar generator, you’re not getting the total value of your investment. In this case, a generator with a smaller capacity could be much better suited to your requirements.

Of the three options above, the River Pro has the lowest capacity. The DELTA has the mid-range capacity, and the DELTA Pro has the highest capacity EcoFlow offers.

Life Cycles

The life cycle of a solar generator is the number of times you can charge and discharge it before its storage capacity begins to deteriorate. A higher life cycle means that your generator will last longer. 

In general, the higher the capacity of your generator, the longer its life cycle will be. However, this isn’t always the case—some generators with a lower capacity may have a longer life cycle than those with a higher capacity. It’s always a good idea to check the specs.

Output and Input

The output of a solar generator is the amount of power it can provide at one time. The input is the amount of power the generator needs to recharge. 

You’ll generally want a generator with high output and low input. That way, you can recharge your devices quickly and efficiently.

As you’ll see with the DELTA collection, the input and output capacities increase as you go up in the model classes.

Size

The size of a solar generator will partially dictate how easy it is to store and transport. Say you’re planning on using your generator while on site for a contracting job that doesn’t have outlets readily available, for example. You’ll want a solar generator that’s small and portable enough to move around with you as needed.

The River and DELTA generators are all compact and lightweight, making them easy to transport. The DELTA Pro even has a built-in handle and wheels for added convenience.

All the EcoFlow solar generators are compact by design. Many traditional fossil-fuel generators are bulky and take up unnecessary space, not to mention the noise and toxic exhaust. But EcoFlow solar generators save space and help avoid clutter.

Weight

The weight of your solar generator will also play a role in how easy it is to transport. If you plan to take your generator with you when you travel to power your tools, you’ll want one that’s lightweight and easy to carry – especially if you need to go up and down stairs.

However, if you just need the power to go with you from point A to point B and then remain stationary while you use it, a heavier, more powerful generator option might be worth your while. 

Wrapping Up

When choosing the right solar generator for your needs, there are a few things you’ll want to keep in mind. Capacity, life cycles, output and input, size, and weight are all critical factors to consider. Keep these in mind as you review the various models in our River and DELTA series, and you’ll be sure to find the perfect generator for your power tool needs.
