SRK-PRO comes with 4 x 5.12kwH server rack batteries along with the battery racking system, giving you over 20kwh+ of battery capacity!

Complete Off-Grid Solar Kit 12K

Complete Off-Grid Solar Kit 12K can power just about anything you need in an off-grid situation. With over 9,000 Watts of continuous split phase (120/240V output) inverter setup, your SRK solar kit is powerful enough to run lights, fridges, cabins, workshops, homes, 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 120V and 240V power output, you’ll be in a much better position when it comes to long-term versatility and reliability.

What Can This Off-Grid Solar Kit Actually Power?

Solar kits come standard with 4 x 5.12kwh high quality, lithium server rack batteries (maintenance and fume free). This equates to a rough 20.4kWh of useable battery bank on top of the 8,760+ watts of solar panels that will be generating 8,760 watts 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 52,000W of power each day (or 1,566kw/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.

This is the perfect solar kit for a full off-grid living setup, home backup, or for larger RV system / mobile business applications.

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 tying into 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 and tie power and your off-grid battery backup.

2. Battery Bank Jakiper Server Rack Batteries

The Jakiper 48V Server Rack Battery contains the latest LiFePO4 lithium cells, which means it combines exceptional performance with a long-lasting lifespan. One of the things that set this deep-cycle battery apart is the fact that it offers truly outstanding value. Typically, you would expect to pay far more for a battery of this quality.

With a storage capacity of 5,120Wh, a single Jakiper 48V Server Rack Battery can store a tremendous amount of solar power. While one battery can certainly store enough power to be a practical backup battery bank for blackouts and temporary power outages, it is its unique, rack-mountable design that really makes it an appealing option for larger-scale solar applications.
