Description

Sol-Ark 12K All-In-One Solar Generator Hybrid Inverter. Solar Plus Storage. Made Simple.
This is an impressive system, providing grid-tie, off-grid, and hybrid functionality in a single unit. It is the world’s most efficient battery-based inverter system, that is just as happy to operate without batteries. With the Sol-Ark 12K, you have the flexibility to build your system the way you want, and adapt it according to future needs. All in one unit.

If you’ve had the pleasure of visiting the Sol-Ark website or viewing some of their videos, you will quickly realize how challenging a task it is to describe this multi-function energy hub.
On one hand it is a grid-tied inverter, connecting your solar directly to the grid.
It can also function as an off-grid inverter, sending energy into your battery bank and interfacing with generators.
Then again, it’s also a high-efficiency hybrid inverter, able to use a battery bank to maximize your system’s internal consumption, and interface with the utility in either a buy/sell, or buy-only configuration.

Here is an overview video…

And a webinar covering greater detail…

Consider the rich set of components pre-installed in the Sol-Ark system. The additional labour and additional parts required for any other hybrid inverter system to be able to come close to the Sol-Ark’s core functionality, makes this system an exceptional value.
