We've Thought of Everything, So You Don't Have To.

This is the complete off-grid solar power kit you've been looking for! CSK-PLUS will power just about anything you need in an off-grid situation. With a 4,000W split phase (120/240V) inverter, your CSK-PLUS solar kit is powerful enough to run lights, fridges, small workshop, well-pump and more!

Easily expandable in the future, you can add more batteries and more solar panels as you need.

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, air conditioner and more...

When you buy this solar kit, which includes built-in 120/240V power output, you'll be in a much better position when it comes to long-term versatility and reliability. This is the smallest off grid solar kit that CAN handle 240V output for powering things like a well-pump.

NOTE: Input needs to be rated at 240Vac.

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. ShopSolarKits.com 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?

Your solar kit will include Tier-1 / Grade A solar panels. 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.

Buy With Confidence. All of Your Questions Answered:

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 batteries. Every area of this kit is expandable.
What solar panels are included with this kit?

You'll receive 200 watt 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.
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. 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. NOTE: Input needs to be rated at 240Vac.
Can I sell power back to the grid with this system?

No. This kit is not designed to sell power back to the grid. However, you can use grid power to recharge your batteries.
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'. For specs see below:
Charge Temp Range (°C): 0°C (32°F) / 55°C (131°F) Discharge Temp Range (°C): -30°C (-22°F) / 55°C (131°F) Optimal Discharge Temp Range: 15°C (59°F) / 35°C (95°F)
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.

Powerful & Simple.

The CSK-PLUS comes standard with 2 x 200ah AGM batteries giving you 200ah of useable battery capacity. This equates to rough 2.3kWh of useable battery bank on top of the 400 watts of solar panels that will be generating an additional 1kw of power per hour while the sun is shining.

If we assume there's roughly 6 good sun hours in most states, the solar panels will produce around 2.4kw of power each day (or 72kw/month).

We really only need 15-18 hours of battery bank storage in order to get us through the night and to when the sun comes back up the next day, so anything over and above this would be considered backup for cloudy days.

The CSK-PLUS kit is perfect for well-pump backup, small off-grid cabins, home backup, or for basic RV system / mobile business applications. Easily expandable, you can add more batteries and more solar panels in the future!

Average Expected Run Times

Your kit comes with just about everything you need making installation and setup very easy. If you're looking for a simple off-grid solar kit, this 12V system is the perfect option. The 400 Watts of solar panels can easily be added to and the 4,000 watt 120/240V inverter will power just about anything you throw at it!

Appliance	Run Time
Refrigerator (100 watts)	24+ hours
Smartphones (5-7 watts)	400+ hours
Tablets (25-40 watts)	80+ hours
Laptops (50 watts)	48+ hours
Electric Blanket (Queen Size, 75 watts)	32 hours
50" LED LCD TV* (65 watts)	37 hours
Microwave (1,000 watts)	2+ hours
Basecamp LED Light (6 watts)	400 hours
CPAP Machine (30 watts)	80+ hours
Well Pump (120V or 240V)	Standard Useage (multiple minutes at a time)

Can I use grid power to charge the batteries and/or tie this system in with my on the grid home though?

The short answer is yes. Our off grid kits come with inverter/chargers, meaning you can suck power out of the batteries as well as throw juice back into the batteries via a generator OR any form of AC shore power (aka your grid tied home). When it comes to backing up your home or tieing it in to your existing electrical system, you'll need to work with an electrician to get some form of transfer switch that will allow you to go back and forth between your homes grid tie power and your off grid battery backup.
