Sol-Ark- 8k All-In-One Hybrid Inverter

The Sol-Ark 8k is your best choice solar inverter! It’s an all-in-one, pre-wired inverter that is flexible, efficient, and affordable. Everything you need comes in one box, keeping your cost LOW and installation SIMPLE.


There has been a lot of excitement in the solar industry since the Sol-Ark 8k hit the market! Through this inverter, the Sol-Ark company has proven themselves to be innovative leaders when it comes to solar inverters. So what’s all the hype about? The Sol-Ark 8k is a an all-one, pre-wired inverter system that is flexible, efficient, AND affordable!

The Sol-Ark 8k is All-in-One

Everything you need in one box! Inside of one Sol-Ark 8k inverter, you are also benefiting from the following built-in features:

  • Color touch screen interface
  • AC In/Out: 9kW
  • AC Load Out: 20kWpk
  • Battery Temp sensor
  • Auto-Generator Start
  • PV Rapid Shut Down
  • Built in Arc Fault and Ground Fault detection
  • External current sensors
  • Batter communications
  • Grid Tied Mode: Sell your power to the grid
  • Meter Zero Mode: Zero your whole home power
  • Time of Use: Use batteries to avoid $$ power
  • 120/240/208V
  • Smart Load: Programmable Loads for high power off-grid items saves battery capacity
  • AC Coupling: Add backup to 7kW of existing Grid Tie Installs
  • Peak Shaving: Reduces peak demand charges

The Sol-Ark 8k is Flexible

The Sol-Ark inverters can be used in grid-tie, hybrid, and off-grid systems and don’t have expensive battery restrictions like other inverters do; they can be used with the widest variety of 48V battery chemistries.

The Sol-Ark 8k is Efficient

The Sol-Ark 8k sets records and tops Efficiency tops Tesla, Outback, Magnum, Pika, Solar Edge, and Sonnen! The Sol-Ark 8k boasts only 4% losses, whereas most system losses today are around 14% in battery based systems.

Sol-Ark achieved this with the innovative design of the sol-ark 8k that combines all of the electronics into a single DC Transformerless system (reducing the cost by 25%+). Eliminating transformers allowed Sol-Ark to achieve 97.0% efficiency. That is unbelievably high while using affordable 48V external batteries. Several expensive 380V battery solutions claim high efficiency but fail to include the 380V conversion losses to an internal 50V battery.

The Sol-Ark 8k is Afforable

Because it’s an all-in-one solar inverter, the Sol-Ark 8k requires minimal additional hardware, keeping the cost low and installation simple. When stacked up against equivalent systems using other inverters, they are the most affordable option by a wide margin. See the comparison charts below!

Comparison Charts

Other popular transformer-less systems require expensive certified batteries while the Sol-Ark can work with any battery!

The Sol-Ark costs less than popular battery based inverters once you factor in required hardware:
