The Sol-Ark 8K All-In-One Solar Generator System


All-In-One Solar Generator Hybrid Inverter Reduces Costs 50%+

sol-ark 8k
Next Generation Efficiency

3X Better! Only 4% losses vs. 14% in today’s battery based systems

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.

5-Year Standard Warranty

10-Year extended warranty available
