This is the complete off-grid solar kit you've been looking for. HBK-PRO will power just about anything you need in an off-grid situation. With a 6,000W split phase (120/240V) all-in-one inverter, the HBK-PRO solar kit is powerful enough to run everything from lights, fridges, TV’s, fans, small workshops, well-pumps, office space and more.

Easily expandable in the future, you can add more batteries and more solar panels as you need. This is an all-in-one plug-and-play solar kit that has the ability to hook up to solar panels, wind, fuel/backup generator and/or utility power - So whether you're looking to run your RV, off-grid home/cabin or for an emergency backup solar system at your home, the HBK-PRO solar kit comes with everything you need to get up and running with solar power in just hours.

You might have already noticed this, but most off-grid solar kits available today only include a 120V output inverter which is NOT able to run things like a 240V well-pump, dryer, some air conditioners and more...When you buy this solar kit, which includes built-in 120/240V power output and a 200+ pound lithium battery bank on wheels (backed by a 10-year warranty + designed and assembled here in the USA) you'll be in a much better position when it comes to long-term versatility and reliability.

If you’re looking for a complete off-grid solar kit that's simple to setup, easy to use and comes with high quality, long lasting parts, look no further. HBK-PRO checks all of the boxes and will have you up and running with off-grid power quickly and easily.

Our kits include solar-specific equipment to get you started, but keep in mind that you'll need to purchase additional items like installation tools, grounding rods/wire, and any AC components you might need. We highly recommend bringing in a certified solar installer or master electrician to help with the installation process to ensure a safe and reliable system that meets all relevant codes and standards. Solar Panel Disclaimer: If you purchase a solar kit without solar panels, you will be responsible for ensuring the compatibility and configuration of your solar panel array. Our solar kits include professionally designed solar panel arrays that work within the parameters of each inverter. There are minimum and maximum input voltages with each inverter that you will need to be aware of so that you do not damage your inverter and/or void your warranty. is not responsible for any damages or issues that occur when you do not purchase the solar panels with your kit.

What Type of Solar Panels Are Included?

We only include Tier-1 / Grade A solar panels in our solar kits. They are always monocrystalline and come with at least a 25-year power output warranty. We only source and supply solar panels from reputable brands that have been in business for many years. For more information on your solar panels, click to watch our video.

What Kind of Batteries Are Included?

We almost only include lithium iron phosphate batteries in our solar kits. This is because they are the longest lasting and safest battery option available today. We only source and supply batteries from reputable brands that ideally have US based operations and support teams. We stand behind the batteries we sell and because of that, your lithium batteries will always be covered by a long-term, comprehensive warranty. For more information on your battery bank, click to watch our video.

Does This Kit Come With Setup Instructions?

In addition to guaranteed lifetime customer support, we also provide you with a custom wiring diagram and commissioning guide for setting up your solar kit. Whether you are planning to hire a professional or install it yourself, this information will set you up for success when it comes to getting your solar power system up and running properly. In addition, you’ll also unlock lifetime access to The Solar Hub, where you’ll find instructional videos, articles, troubleshooting guides and tips, so that you can level up your solar knowledge and get the most out of this kit.

What warranty is included with this solar kit?

When you buy this solar kit, you are covered by the full manufacturer warranties on each component. Plus, you’ll receive our lifetime customer and technical support.

Can I expand this system in the future?

Yes, you can easily add more solar panels and batteries to all of our solar kits.

What type of solar panels are included?

You'll always receive monocrystalline solar panels from one of the leading brands in the solar industry. Backed by a minimum 25-Year power output warranty. We do our best to source all of our solar panels from North America, Mexico or Vietnam. Most popular brands we carry are Aptos, Phono, Mission and SolarEver.

How long will my battery bank last?

You'll be covered by a 5 or 10 year warranty depending on if you have an AGM (5 years) or Lithium (10-Years) battery bank. To calculate daily run times, divide the total battery bank watt hours by your average load in watts to get rough hours of run time.

Can I install the system myself?

We've created the kits for absolute simplicity. That said, we highly recommend getting the help of a professional installer / certified electrician. You should plan on potential costs associated with this as well.

Can this kit handle a well-pump and/or other 240V appliances?

Yes! This kit comes with an all in one 6,000W pure sine inverter with built-in split phase capabilitiies. This means it can handle things like well pumps, dryers and 240V air conditioning units.

Can I use a generator or the grid to charge my battery bank if needed?

Absolutely. Your inverter comes ready to go with an AC input where you can hook up a stand by generator for charging the batteries on cloudy days or at night if needed. You can also use the grid as the AC input source if it's available. e with a direct AC charger.

Can I sell power back to the grid with this system?

No you cannot. However, most people who buy these kits are looking to gain power and grid independence and opt for storing or using any excess power they may have!

How big is all of this? How much space do I need?

The solar panels will be the biggest in terms of taking up space. Other than that, everything should fit in the back of a truck or in the corner of your home / garage. Panels are the only things you can leave outside, everything else should be stored somewhere dry and temperature controlled.

Where is this equipment made?

We do our best to source as much product from North America as possible. Our solar panels are USA, Mexico or Vietnam and most of our batteries and inverters are designed and assembled in the USA.

Do tDo the batteries need to be inside or outside? Does it matter?

Lithium batteries like to be around the same temperature as humans. They also like a temperature controlled environment. So putting them in a garage that is 40F' in the morning and 110F' in the afternoon is NOT ideal. They'd prefer to be in a basement that sits somewhere around 60F-90F on a consistent basis. That said, lithium batteries can be used when below 32F' but not charged unless they are above 32F'

Do I need to buy anything else?

You'll have all of the essential parts you need to get up and running...However, you will want to plan on a trip to the hardware store to buy any necessary installation tools, ground rods/wire as well as UniStrut if needed for mounting the solar panels. Outside of this, you'll be getting all of the most important components in your kit!

Impressive kit

I am planning to mount the panels on a garage yet to be built. I settled on the HBK-PRO and ordered it early, so I don't have it set up yet. Cleared area in basement, mounted inverter.

After 36 yrs as professional electrical engineering in power a couple of them were PV. The introductory videos from shopsolar were excellent but I've worked off of schematics so long, I'm handicapped without them. I usually read the owner's manual before I unbox the equipment. Found a tiny one in box and pdf on line under a different number but I didn't find which terminal was battery + and -. Those who don't read would be done by now. I take that criticism all the time but I burn up less equipment.

The equipment is light years ahead of what I used to see. Can't wait to see it running.

Off grid system, working great

We installed this system on our ranch, 100% off grid, we are learning this solar living, we added at big battery, works great in the spring, summer and fall months. Winter takes some doing due to inversions and cloud covers, had a system installed so that we can charge by generator which takes a 1/2 day or so. Had great support from the sales and technical teams, will buy again
