Disclaimer: Each solar kit includes solar-specific equipment to get you started, but please keep in mind that you may 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. Also, if you purchase a solar kit without solar panels, you will be responsible for ensuring the compatibility and configuration of your solar panel array. Each solar kit includes professionally designed schematics 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. WARNING! Connect the battery terminal wires to the charge controller FIRST, then connect the solar panel(s) to the charge controller. NEVER connect solar panel(s) to charge controller before the battery.

Just got it

Just got everything online from our kit. Only took an hour or two to get fully installed and running. So far it has been a phenomenal system. The instructions took a little deciphering purely cause I'm a little hesitant of electricity after I rode 995V and was extremely paranoid about hooking something up wrong. Shop solar as by far been the best place I have found to order systems and share it to everyone.

Test 1-2 testing 1-2

Im still very new and trying to learn the ins and outs of solar.

I just did a small test, the well pump ran for a cycle approx 30 to 45 seconds and was using 49% on my inverter led display. My AO smith 900 hybrid water heater runs at 18% and the fridge ran at 12% and im not sure if the deep freeze was running during any of these tests. I did not run them all at once. I can turn off the well breaker on and off as needed while turning off the water heater.

I'm going to take a weekend kill the main power and see how long we can go off grid running just the basics.

I plan on changing over to lithium battery's and adding a couple solar panels in the near future. It Seems capable of doing what I need it to do. WATER AND FRIDGE. Thank you Shop solar

Lots of Planning! Working Great!

My 4,000W 120/240V System is finally up and running. It works great so far. Planning for location and space to build is important. This took me several weeks to finish. The batteries (100#+) and inverter are VERY heavy so be prepared for your shipment with a dolly. With my install complete my home shop is 100% off-grid. I'm running a fan, seven LED 8' lights, a radio, chargers, occasional air compressor, and more, and it's only using about 10% of the power. I am super pleased with ShopSolarKits' sales, delivery, notifications, training, and diagrams. I did this completely by myself as a first-time solar buyer. For my install I added a subpanel with 120 and 240 output, and a plastic wall box to house excess wires coming in from the roof panels.

Good purchase

The kit came in 9 boxes within a week. Quality looks good. I'm experimenting with how much off grid power can supply my needs and it's not quite as much as hoped. Still not totally comfortable with understanding all options available with various settings.

Rookie solar system

I think it is doing just fine. I wasn’t sure right at first, but I believe it is doing what it is supposed to and I like it a lot. Also the service after the sale has been great. I’ve called a couple time with stupid questions and have been treated promptly, professionally and well. Thanks guys!

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.

How much power can this solar kit generate per month?

If we assume there's roughly 6 good sun hours in most states per day, the solar panels will produce around 2.4kW of power every single day of the week, for a total of approximately 70KW per month!

Can I expand this system in the future?

Yes, you can add more solar panels, charge controllers and batteries to this kit. But consider the specifications based on the system voltage. If otherwise unsure, you can consult our solar technicians.

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 support a well-pump and/or other 240V appliances?

Absolutely! The kit includes a 4,000W pure sine inverter/charger setup with built-in split phase capabilities. However, before using large motor loads, please ensure that you refer to your equipment's specifications first to verify the start-up and working amperage.

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.

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

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!

How long will it take for me to get my kit after ordering?

If you're in the lower 48 states we do our best to get you your order within 9-12 business days. Recently with the incredible demand for products, our delivery times to customer's door are averaging around 10-15 business days. You will receive your tracking numbers as soon as they are available.

How much does shipping cost?

Shipping is calculated at checkout. Because we specialize in shipping straight to our customers, you'll get the lowest possible shipping rates when you buy from us. If you have any questions about shipping, you can give us a call at 877-242-2792

Will I be able to track my order and deliveries?

You will receive your tracking numbers via email and/or text message as soon as they are available. So please make sure you use a good Email address when ordering or a phone number that can receive text messages for your your tracking information. Also, please expect to receive multiple deliveries and packages as we ship from multiple warehouses to keep costs down.

What's Your Return Policy?

We try and keep returns simple and easy. We do not charge restocking or return fees. That said, if you decide to return it because you no longer want it, you'll just pay return shipping. If something arrives damaged, we'll cover all of the costs to get you a properly working product.

What happens if stuff arrives damaged?

We stand behind what we sell and we'll take care of the costs of getting you a new working product. Just reach out to us if this happens and we will get you all taken care of.

Does the kit come with a wiring diagram/setup guide?

Yes, you'll get our custom setup diagram and instruction PDF document along with all of the manufactuer guides and user manuals. We've also created the SolarHub which you get lifetime access to when you order from us.

Where do you ship from?

We have 3 main distribution points (CA, TX, NY) along with multiple suppliers across the USA. We ship from multiple different warehouses in order to try and keep costs as low as possible for our customers.

Do you offer financing?

Yes we do! We have 2 financing options which you can learn more about if you keep scrolling down this page.

What sort of after-sale customer support do you offer?

You can reach us Monday to Friday via phone, live chat or email. You'll also get free, lifetime access to the industry leading "Solar Hub" - Where you'll find all of our diagrams, installation manuals, troubleshooting guides and more!

Can I qualify for the 30% federal tax credit if I order this kit?

Yes, if you order this solar kit and install it before the end of the year, you may be eligible to claim 30% of its cost as a credit on your federal tax return. This is made possible by the Solar Investment Tax Credit (ITC), which is part of the Inflation Reduction Act.
