"Bring Your Own Panels" solar ready kits include everything you need to get hooked up with a useable, stand-alone battery based power system. Your kit includes a reliable, split phase (120/240V) output inverter along with all the parts and pieces needed to hook it up to your lithium iron phosphate battery bank, which is covered by a 10-Year Warranty. 

Wether you already have solar panels, or would like to source them yourself locally, our BYOP solar kits come ready to easily connect to almost any type of solar panel array. This kit does NOT include solar panels, however you can connect up to 13KW of solar panels to this system.

How Do I Recharge the Battery Bank Without Solar Panels?

Great question! You can charge your batteries through the inverter/charger three main ways: 

1. Source some solar panels and/or wind turbine (DC power) and connect them to the system.

2. Using grid power if available by plugging your system right into the grid so that if your battery gets low, you can charge it back up from the grid (just like charging a cell phone battery).

3. You can connect and use a fuel powered generator to recharge your battery bank.

Whether you are a homeowner that wants to be prepared for power outages and natural disasters, or you just want to reduce your monthly electricity bill by offsetting the costs with clean, reliable solar electricity, the Sol-Ark is the perfect solution!

Stop wasting money on inefficient, overpriced inverters. Invest in one of the most versatile and effective solar power management systems out there today. When you consider its wide array of features, industry-leading warranty, and the incredible value you get, it is no wonder that the Sol-Ark 12K is quickly becoming one of the most popular pre-wired hybrid inverters on the market today!

Why the Sol-Ark 12K?

  • Outstanding Efficiency
  • Industry Leading Power
  • Unrivaled Versatility
  • User-Friendly Simplicity
  • Affordability and Support

  • Outstanding Efficiency

    The Sol-Ark 12K offers next-generation efficiency, meaning it is the most efficient battery + solar power system available today! In other words, you will be able to use more of the electricity your solar panels generate than you ever could with any other hybrid inverter!

    Industry Leading Power

    The Sol-Ark 12K allows you to use solar power just like you would use electricity pulled from the grid, meaning you can use it to directly power 120V, 240V, and 208V appliances! No more worrying about compatibility issues. No matter what type of electronic devices and appliances you own, the Sol-Ark 12K can handle the job! 

    Un-rivaled Versatility

    The Sol-Ark 12K gives you the ability to draw power directly from your solar panel array, from your battery system, or from the grid. In other words, it is one of the most versatile power management systems on the market today. In fact, you can even feed excess solar electricity back into the grid for cash rebates and discounts on your monthly utility bills!

    The fact you can use the Sol-Ark 12K with or without a battery bank also offers another layer of versatility. 

    User-Friendly Simplicity

    The Sol-Ark 12k is controlled with a full-color touch screen display. Monitoring and programming the unit is incredibly simple and Sol-Ark offers live customer support 7 days a week!

    It is also much easier to install and expand than anything else on the market, so you will not have to spend thousands of dollars incorporating the Sol-Ark 12K into your current electrical system. 

    Affordability and Support

    While the Sol-Ark 12K is one of the most advanced units on the market today, it is available at a budget-friendly price. When you choose Sol-Ark, you are paying for innovation, performance, and durability, rather than brand name.

    For perspective, the Tesla Powerwall 2 operates just like a Sol-Ark 12K, but it costs thousands of dollars more and it is not backed by an outstanding 10-year warranty!

    What Can You Use the Sol-Ark 12K for?

  • Grid-Tied Mode – You can feed excess solar power back into the grid, which can result in cash rebates or reduce the cost of your monthly utility bills.
  •  

  • Meter Zero Mode – Use solar power to meet all of your home’s electricity needs! If your solar array is capable of generating enough power, you can use it to meet all of your electricity requirements. This means no utility bills!
  •  

  • Time-of-Use Mode - Use a combination of solar and battery-stored power to minimize grid power usage when the rates are at their most expensive. This saves you money by lowering the amount you have to pay to the utility companies!
  •  

  • Smart Load Mode - Use a programmable output to decide when your solar power will be fed directly into your home’s electrical system, or stored in your batteries.
  •  

  • Off-Grid Applications – Store all of the power your solar panels generate in your battery bank, so you can run your entire home off of the grid!
  •  

  • AC-Coupling – Add the Sol-Ark 12K to your existing grid-tied system to expand and improve its capabilities.
  •  

    Battery Backup Management – Strictly use the Sol-Ark 12K to run your emergency preparedness battery system. Let the unit monitor and charge your battery bank, so you have power when you need it the most!

        Using 2 to power my house

        I would prefer a third, but these two do everything I want. Only about 20 cycles in, but going strong. Easy to install and the bms is all internal and very simple. It does require attention, as they don't drain equally.

        Shopsolarkits set me up with a customized WHK3. We doubled the panels, doubled the inverters and doubled the batteries! The only parts I’m waiting on is stuff I didn’t purchase thru SSK! Love the fast response time to questions after the sale.

        Great for tiny house

        Great for our tiny house! We have had two 5.3 kw Big battery packs powering our tiny house trailer for about six months. We have a gas hot water heater and stove so so our main power draws besides miscellaneous items plugged in are the Apartment sized fridge, a chest freezer, tv, and air conditioning. We weren’t sure if we would be able to run the AC but as long as we turn it off with still about two hours of daylight on our panels are batteries end fully charged. It has been a hot summer with days around 95 to 105° so this has been a welcome surprise. If we have used our batteries too low for the night, a quick half hour running of the generator tops them off. They were easy to install and are neat and compact.

        The Sol-Ark 12K is the ideal hybrid inverter for anyone that is looking for dependable access to off-grid or on-grid solar power, no matter what life throws at them. Whether you are a homeowner that wants to be prepared for power outages and natural disasters, or you just want to reduce your monthly electricity bill by offsetting the costs with clean, reliable solar electricity, the Sol-Ark is the perfect solution!

        Stop wasting money on inefficient, overpriced inverters. Invest in one of the most versatile and effective solar power management systems out there today. When you consider its wide array of features, industry-leading warranty, and the incredible value you get, it is no wonder that the Sol-Ark 12K is quickly becoming one of the most popular pre-wired hybrid inverters on the market today!

        Why the Sol-Ark 12K?

      • Outstanding Efficiency
      • Industry Leading Power
      • Unrivaled Versatility
      • User-Friendly Simplicity
      • Affordability and Support

      • Outstanding Efficiency

        The Sol-Ark 12K offers next-generation efficiency, meaning it is the most efficient battery + solar power system available today! In other words, you will be able to use more of the electricity your solar panels generate than you ever could with any other hybrid inverter!

        Industry Leading Power

        The Sol-Ark 12K allows you to use solar power just like you would use electricity pulled from the grid, meaning you can use it to directly power 120V, 240V, and 208V appliances! No more worrying about compatibility issues. No matter what type of electronic devices and appliances you own, the Sol-Ark 12K can handle the job! 

        Un-rivaled Versatility

        The Sol-Ark 12K gives you the ability to draw power directly from your solar panel array, from your battery system, or from the grid. In other words, it is one of the most versatile power management systems on the market today. In fact, you can even feed excess solar electricity back into the grid for cash rebates and discounts on your monthly utility bills!

        The fact you can use the Sol-Ark 12K with or without a battery bank also offers another layer of versatility. 

        User-Friendly Simplicity

        The Sol-Ark 12k is controlled with a full-color touch screen display. Monitoring and programming the unit is incredibly simple and Sol-Ark offers live customer support 7 days a week!

        It is also much easier to install and expand than anything else on the market, so you will not have to spend thousands of dollars incorporating the Sol-Ark 12K into your current electrical system. 

        Affordability and Support

        While the Sol-Ark 12K is one of the most advanced units on the market today, it is available at a budget-friendly price. When you choose Sol-Ark, you are paying for innovation, performance, and durability, rather than brand name.

        For perspective, the Tesla Powerwall 2 operates just like a Sol-Ark 12K, but it costs thousands of dollars more and it is not backed by an outstanding 10-year warranty!

        What Can You Use the Sol-Ark 12K for?

      • Grid-Tied Mode – You can feed excess solar power back into the grid, which can result in cash rebates or reduce the cost of your monthly utility bills.
      •  

      • Meter Zero Mode – Use solar power to meet all of your home’s electricity needs! If your solar array is capable of generating enough power, you can use it to meet all of your electricity requirements. This means no utility bills!
      •  

      • Time-of-Use Mode - Use a combination of solar and battery-stored power to minimize grid power usage when the rates are at their most expensive. This saves you money by lowering the amount you have to pay to the utility companies!
      •  

      • Smart Load Mode - Use a programmable output to decide when your solar power will be fed directly into your home’s electrical system, or stored in your batteries.
      •  

      • Off-Grid Applications – Store all of the power your solar panels generate in your battery bank, so you can run your entire home off of the grid!
      •  

      • AC-Coupling – Add the Sol-Ark 12K to your existing grid-tied system to expand and improve its capabilities.
      •  

        Battery Backup Management – Strictly use the Sol-Ark 12K to run your emergency preparedness battery system. Let the unit monitor and charge your battery bank, so you have power when you need it the most!

            Using 2 to power my house

            I would prefer a third, but these two do everything I want. Only about 20 cycles in, but going strong. Easy to install and the bms is all internal and very simple. It does require attention, as they don't drain equally.

            Perfect!

            Shopsolarkits set me up with a customized WHK3. We doubled the panels, doubled the inverters and doubled the batteries! The only parts I’m waiting on is stuff I didn’t purchase thru SSK! Love the fast response time to questions after the sale.

            Great for tiny house

            Great for our tiny house! We have had two 5.3 kw Big battery packs powering our tiny house trailer for about six months. We have a gas hot water heater and stove so so our main power draws besides miscellaneous items plugged in are the Apartment sized fridge, a chest freezer, tv, and air conditioning. We weren’t sure if we would be able to run the AC but as long as we turn it off with still about two hours of daylight on our panels are batteries end fully charged. It has been a hot summer with days around 95 to 105° so this has been a welcome surprise. If we have used our batteries too low for the night, a quick half hour running of the generator tops them off. They were easy to install and are neat and compact.
