The New Sol-Ark 12K All-In-One Solar Generator System

12K Sol-Ark Hybrid Inverter

Sol-Ark 12K
Solar Generator

Hybrid Inverter Reduces Costs 50%+

Boosts PV energy 10-20% without increasing PV array size and reduces storage inverter costs up to 30%

Improve battery efficiency by 10-15%; Partial Charge Carbon AGM’s round trip efficiency is 98% vs. wet cell 80%

Sol-Ark 12K’s All-In-One design cuts install time in half. With 2x MPPTs, and 9kW continuous / 20kW peak inverter, a user friendly wiring area, and remote monitoring built in. We also guide you 7 days a week via our engineering support. Call us!

 Sol-Ark 12K supports simultaneous DC and AC coupling up to a combined 16.5kW of PV.

Sol-Ark 12K acts as a massive uninterruptible power supply with a lightning fast 4ms transfer time.

Approved for: UL 1741 SA Rule 21, HECO, & Canada

PREPA Approved (Puerto Rico)

120/240 & 3P

Next Generation Efficiency

3X Better! Only 3.5% losses vs. 14% in today’s battery based systems

Split Phase & Three Phase

Sol-Ark’s 12K pumps out power just like the grid, allowing you to power 120V/ 240V/208V appliances 

Grid-Tied, Hybrid, Off-Grid

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


Sol-Ark is expandable from 5 to 52 (16.5 kW) solar panels and 0-32 batteries. Per 12K unit.

10-Year Standard Warranty

No need for additional warranties. The 12K comes standard 10-year warranty right out of the box.

Customize Your System

Sol-Ark is expandable to fit your needs. An Installer will be happy to help size your system
