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.

Everything working as advertised

Ordered kit late last year and have everything up and working properly. Very happy with the way everything was delivered and the service we've got each time we've called in to get help. Will add more pictures soon.

Good Kit needs some fine tuning

This is an all inclusive review of this Kit that I personally installed and own with slight tweaks read the whole thing for the truth.

First of all so we're clear when I purchased this kit it originally had Mammoth 9.6 KW batteries times two. Mammoth batteries are made by the Big Battery Company there are a lot of batteries on this site that offer Big Battery brand under different names, they are made in America! As you can see they upgraded the battery in this kit. My batteries will charge to 100% then during discharge instantly say 80%, and we barely scrape by overnight usually around 20% or less and sometimes 0% two totally dead batteries. Keep in mind at 19.2 KW combined, my system only requires less than 15 KW under normal usage. These batteries aren't great. In fact I'm running just three box fans, a refrigerator and a 1.5 ton mini split with a 19 Seer rating. It is apparently too much.

The kit did come with the Rich Solar inverters. However I was talked out of them by the tech team and introduced to EG4 inverter brand. Please keep in mind that EG4, Rich Solar, Sunpower, Sungold Power and others are all rebranded and the same company all made in China. Yet you will pay more for all of them almost double! Without the advantage that the EG4 has by offering 8,000 watt capacity and 500 VOC. What that means to you is you can run up to 20, 400 watt solar panels through one single inverter. However if you want to run 240 volts which most people need to. You have to buy two…

I Thought it was Too Good to be True

The process of putting together a solar system seems very intimidating at first but ShopSolarKits made it super easy. From the customer service to the quality products, I couldn't be more thankful!!

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 (up to 16kw so more than double) as well as up to 8 x powerwalls. You can even stack another inverter if you need more output. Every area of this kit is expandable.

What solar panels are included with this kit?

You'll receive 390W 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 10-year warranty. The battery is Lithium LFP meaning it's rated for up to 6,000 lifecycles (15+ years of daily use). 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 this 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 is capable of running 120V and 240V appliances. This includes 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.

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

No you cannot. However, most people who buy this kit 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 come on a pallet and can be left inside or outside. The batteries are the biggest and heaviest deliveries at around 4 ft tall and 2 ft wide. The inverter is about 3 ft by 1.5 ft and weighs 75 lbs. All together you'll need a good corner of a garage or a spare bedroom worth of space for storing all of the equipment before installing it.

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?

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 everything you need to get up and running with our kits. That said, you will want to plan on a trip to the hardware store to buy any necessary installation tools, ground rods and 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 5-15 business days. Recently with the incredible demand for products, our delivery times to customer's door are averaging around 9-12 business days. You will receive your tracking numbers as soon as they are available.

How much does shipping cost?

Shipping is calculated at checkout. You'll get lowest possible shipping rates when you buy from You can also reach out to us here and inquire about shipping, or just give us a call 877-242-2792.

Will I be able to track my order and deliveries?

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.
