Sol-Ark 8k Overview

Next Generation Efficiency

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.

Split Phase

Sol-Ark 8K pumps out power just like the grid, allowing you to power 120V and 240V appliances simultaneously

Grid Tied, Hybrid, or Off-Grid

Manages power from Solar, Battery, Grid, Load, and Generator simultaneously


Sol-Ark is expandable from 5 to 36 (11 kW) solar panels and 0-32 batteries. 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.


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!
