sol-ark 8k

The Sol-ark 8k is an all-in-one hybrid inverter. Unlike other inverters, the Sol-Ark inverters require minimal additional hardware, making it very DIY-friendly. When stacked up against equivalent systems using other inverters, they are the most affordable option by a wide margin. See the comparison charts below!

The Sol-Ark inverters can be used in grid-tie, hybrid, and off-grid systems and don’t have battery restrictions like other inverters do. See the image below to find out what is included in just one inverter. Be sure to also check out the new, stackable Sol-Ark 12k inverter with front breaker access points!

This is the most efficient hybrid, all-in-one solar inverter with limitless applications. It is simple to install and powerful enough to work totally off-grid. Has an auto Generator start. Built-in load management with smart load feature. Time of Use and peak shaving features for those who are doing energy arbitrage.

This inverter comes with:

  • Limiter sensors
  • WiFi Plug
  • Solar Panel Tool
  • Toroid to reduce EMF
  • Allen Key
  • Mounting Bracket
  • Battery Temp sensors
  • Battery resister

It comes with a 10-year warranty!
