4000W Complete Off-Grid Solar Kit – 120/240V Output / 12VDC [Choose Battery Bank] + 600 Watts Solar | Off-Grid, Mobile, Backup [CSK-PLUS]. This is the complete off-grid solar power kit you’ve been looking for! This solar kit will power just about anything you need in an off-grid situation. With a 4,000W split phase (120/240V) inverter, your solar kit is powerful enough to run lights, fridges, small workshops, well-pump, and more!
4000W Complete Off-Grid Solar Kit
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.

Powerful & Simple
The CSK-PLUS comes standard with 2 x 200ah AGM batteries giving you 200ah of useable battery capacity. This equates to a 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 are 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 watts 120/240V inverter will power just about anything you throw at it!

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 to your existing electrical system, you’ll need to work with an electrician to get some form of a transfer switch that will allow you to go back and forth between your home’s grid tie power and your off-grid battery backup.
