Solar Generator Options for Power Tools

It’s no secret that most portable generators run on liquid fuel. It’s just how things have been done for years. The problem is, this is not only expensive and inefficient but it’s also damaging to the environment.

Diesel generators have been around longer but most of the newer solar generators outclass the standard diesel. It’s just that people are scared of the “new” technology. Solar generators are less mechanic and consumer nothing in order to produce energy. These use solar energy and convert it to electrical current, which means that as long as there is light there are solar rays coming through to charge the generator, even when it’s cloudy.

Solar generators are much quieter and operate quietly. Which can be a blessing on sites where noise is an issue. It’s also more efficient as it never requires buying fuel and you don’t have to worry about fumes. So it can be used anywhere.

What to look for

Generators can get pretty expensive but it’s often a question of getting what you pay for. You may not need all of that power. Start by looking at the wattage you’ll need for your tools.

The average hand held power tool runs between 300 to 1200. While larger tools can run up to 2000 watts if you are running a 1hp air compressor. If you’re running pumps this number might be higher still.

One method is to add up the wattage of everything you want to power at one time. But this may give you a larger number that will only occasionally be used.

Most electrical items have a starting wattage and a running wattage. The starting wattage is higher. So as long as you’re not starting all the tools at the same time you can actually have them running using a much lower wattage. This is continuous power need vs occasional power need. And as long as you exercise good management with which tools are starting and running you can get away with a smaller generator.

GoalZero is one of the biggest names in solar power. There are options for this generator starting at 150WH (up to this 1250WH)and you can also boost the charging time by buying an extra boulder solar panel for the unit.

This is entirely silent. It’s like it’s not even there, and other than your own cords there are no extra cables to worry about in the work area. The unit has an included rolling cart to make moving it easier. Which at 100lb is a considerable weight. It has a 12V DC current and is only 16x15x12. So it’s really compact at a size smaller than the average mini fridge.

There’s also an AC inverter with three outlets and three USB outlets. So you can also charge a phone or other device at the same time. With two solar panels and 40 hours of charge the generator will run a full sized refrigerator for up to 24 hours.

This may be a better option for someone who needs fewer tools running concurrently. But if anyone wants to work all night or all day using only the generator. It can also be charged via a car adapter or plugged in to an AC outlet and charged. It has two AC outlets and 2 USB adapters.

  • Powerful: This 1231 watt-hour lithium-ion battery is designed to power and charge larger scale electronics, from smartphones & tablets to refrigerators & Televisions
  • The generator 1200 is 60% lighter than comparable portable generators, designed to be easy to carry at only 42 lbs
  • Versatile: the generator 1200 comes with one 12V output, one 19V DC output, two 5V USB ports and an integrated 110V a/C standard outlet to charge a variety of devices
  • Dual charging: multiple outputs can be used at the same time to charge numerous devices simultaneously
  • Minimal noise: compared to gas generators, the generator 1200 makes minimal noise during operation, making it ideal for indoors use, camping, hunting, boating and more

At 42lb it’s a little lighter than the humless and far lighter than the Yeti 1250. It operates absolutely silently and has an LCD to let you know how much charge it has. You’ll have to purchase the solar panels separately though.

Ascent Solar Generator Y1200 can also be charged via AC current and has a maximum capacity of 1231. Which is almost as good as the Yeti 1250. This Generator is actually almost identically sized though, even while being lighter. There are three standard outlets and two USB outlets.

Be Prepared Solar 2500 Watt 200AH Solar Generator & (2) 100 Watt Solar Panels

2500 Watt 200AH Solar Generator & (2) 100 Watt Solar Panels

2500 Watt 200AH Solar Generator & (2) 100 Watt Solar Panels
  • Use For Back Up Power, Camping, Tailgating, Emergencies
  • 2500 Watt/5000peak inverter- (2)100 Watt Solar Panel & (2)100 amp hour battery
  • Includes USB + 12V/24V socket + Voltmeter
  • Includes BatteryMINDer Charger For AC Outlet Charging!
  • Qualifies for the 30% Federal Tax Credit

With a massive 5000 Watt peak this is enough to power a lot of devices at once. The two solar panels (100W) are also enough to give a quick charge. Especially when you take into account the fact that the Yeti 400 is only working on a 20 Watt. The large case is wheeled so it’s pretty portable even though it’s quite big and bulky.

This is a good no frills generator and it has two outlets and that’s it. The solar panels do come with a 30 foot cable. However so it means that you can run the panels outside even while using the unit inside. Choose this unit if you need a lot of power at once. You don’t really need USB or the option to charge by AC or an indicator of power level.
