Easy Install

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. Sol-Ark also guides you 7 days a week via their engineering support.

DC & AC Coupling

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

Next Generation Efficiency
3X Better! Only 4% losses vs. 14% in today’s battery based systems. It boosts PV energy 10-20% without increasing PV array size and reduces storage inverter costs up to 30%. It improves battery efficiency by 10-15%; Partial Charge Carbon AGM’s round trip efficiency is 98% vs. wet cell 80%

Split Phase & Three Phase

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

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.

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