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.

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 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 400W+ 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?

No. This kit has 120V output only. Add another inverter to achieve 220/240V output.

What sort of solar panel racking is included?

We include pre-drilled frames on the solar panels along with standard z-brackets to make mounting the panels to the structure of your choosing as easy as possible. Most of our customers make their own racking systems using locally sourced UniStrut or add one of our ground racks to your order.

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

Absolutely. The Sol Ark 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?

Technically the Sol Ark inverter allows you to sell power back to the grid. 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. 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?

Also, please expect to receive multiple deliveries and packages as we ship from multiple warehouses to keep costs down.

EG4 Battery rack is awesome.

I purchased this rack to replace my regular 19 inch rack. This is much more heavy duty. It looks much better also.

Great Batteries. Great Shipping

I had ordered most of my System from Signature Solar, all went well until the Shipping. It was a Complete Disaster. So when I wanted to increase my Battery Pack I went with Shop Solar. Everything went Perfect, especially the Shipping, it was even better than I had asked for. Wish I'd went Shop Solar from the beginning..

Great service! Product information could use help

I have 2 - EG4 6000W inverters along with 3 - 5.1KW EG4 batteries and 12 - 400W solar panels. I purchased this as a kit from SSK. The kit came with ALMOST everything I needed. I purchased one panel, then added a second panel a few months later. I suggested that, when providing the inverter that a USB to Serial adapter be included for firmware updates. The second panel I ordered came with the adapter. They actually listened to my suggestion and implemented it. Can't ask for much more than that.

Easy to Install some improvements needed

These inverters are all in one you can do up to 8,000 Watts 500 VOC which means you could easily run 20 400 watt solar panels from one inverter! The downside on the PV input power from the solar panels is a tiny set screw that holds the wires in. Rebranded inverters come with a simple Plug and Play setup there are many versions from the same manufacturer. Names like Rich solar, SunPower and Sungold Power to name a few this is the most inexpensive rebranded name of them all so it's the best one minus the connectors as I mentioned above. Also it would be nice if there was a built-in software user bypass other than the battery bypass. So if you're running these in a series you could simply bypass the voltage output so that the other inverters can run independently if you have a problem or it quits working, unfortunately this is not the case. These were sold to me as off-grid so you have to consider there's going to be dust more than a normal neighborhood . This brings me to the inverter filters hold on each side at the top for the intake air flow. The filters are a cheap sponge like plastic material you can wash them out and let them dry I find myself cleaning them weekly. Dust still gets inside of the machines this is huge as you don't want dust in the electronics. The app for this inverter is offered under two different names. Even after talking to customer support they came back to the same conclusion the app is garbage. It lets you know the basics like what is charging and…
