Sol-Ark 15K for whole-house backup

This inverter been working flawlessly along with the EG4 Lifepower4 battery rack for over a month now, and I typically run the house on battery for 8 hours a day (from 4pm to 12am), as I have been testing out the "Time-of-Use" features on the Sol-Ark for automatic switch over to make the move to time-of-use rate plans. The software in this inverter is amazing, and very flexible. It flips over from grid to battery and back again with no noticeable change at all, and if you lose grid power, the failover time is almost instant (around 4ms) with just a slight flicker of the lights. It will run my 1600 Sq. Ft. home with a 200A main service for around 30 to 40 hours before the battery bank gets to 20% SOC, and my house is fully electric except for the heater. Currently I only have it for battery backup, but will be expanding to install solar soon, the entire install was a DIY project for me and it was easy to pull off with ShopSolarKits help. Thank you to ShopSolarKits for the great service and prompt , trouble-free shipping!

This looks amazing!

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?

Yes. This kit is capable of running 120V, 208V 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. 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.

Where should the batteries be installed—inside or outside? Does location matter?

Lithium batteries perform best in temperature-controlled environments, similar to conditions comfortable for humans. For example, placing them in a garage that fluctuates from 40°F in the morning to 110°F in the afternoon is not ideal. A consistent temperature between 60°F and 90°F, such as in a basement, is preferable.

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 ShopSolarKits.com. 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?

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 3-page setup diagram and instruction manual 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 centers (CA, TX, NY) along with suppliers across the US. 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. We recommend consulting a tax professional to make sure you’re eligible to receive the federal solar tax credit.

What is your return policy?

Returns are free in the first 30 days with no restocking or processing fees, although the customer may be responsible for paying return shipping. See our complete return policy on our Shipping, Delivery, and Returns page linked in the footer of this website.

What’s covered by your return policy?
