Sol-Ark 12k All-In-One Hybrid Solar Battery System


The new Sol-Ark 12K all-in-one solar generator system, with its color-touch display,  can be used off-grid or on-grid and with or without batteries.

  • stackable up to 72 kW, and at 20kW peak power
  • 9kW of continuous power for off-grid production
  • Up to 9kW continuous for grid-tied production
  • Simultaneous management of power to and from  Solar, Battery, Grid, Generator, and AC Loads
  • High efficiency (CEC-weighted efficiency of 96%) means less solar is needed!

The Sol-Ark 12K hybrid solar generator system can be used in on grid, off grid, or battery backup solar applications. The Sol-Ark is stackable and expandable so it can grow as your power needs grow. Stackable up to 72 kW, and at 20kW peak power! The all-in-one, pre-wired design makes this system simple to install. Take a look at some of the Sol-Ark 12k built-in features below:

  • Completely pre-wired system – inverter and charge controller included
  • Color touch screen
  • Smart Modes: Grid sell, Off-Grid, Battery, Meter Zero, Time of Use, Peak Shaving
  • Integrated DC Disconnect, Auto Gen Start, Critical Loads panel
  • No Glitch Transfer Switch
  • Smart Load (Prioritize necessities & run luxuries with less)
  • Generator Breaker (up to 12kW generator input)
  • Cloud Monitoring and Programming



  • Grid Sell: sell power back to the utility to reduce your electric bill
  • Meter Zero Mode: Zero your electric bill without adding a new smart meter
  • Time-Of-Use Mode: Use solar and batteries to minimize consumption of grid power when it’s most expensive
  • Smart Load Mode: Prioritize necessities & run luxuries with less


Installation: Unlike many hybrid inverters, the Sol-Ark 12K is an all-in-one unit, which means you don’t have to piece together multiple parts to get basic functions.

Power: Sol-Ark’s 12K pumps out power just like the grid, allowing you to power 120V/ 240V/208V appliances. Sol-Ark is expandable from 5 to 40 (13 kW) solar panels and 0-32 batteries per 12K unit.


  • On grid PV to AC:  96%-96.5%, among the highest in the industry.
  • PV to Battery to AC: 93%
  • Battery: By collaborating with our battery partners, Sol-Ark works to optimize the life of any battery AND you can pair a Sol-Ark 12k with all battery types!


Smart Management: Manages power from Solar, Battery, Grid, Load, and Generator simultaneously. Users can quickly repair or adjust system without being on site with remote access features and app.

AC/DC Coupling: Supports simultaneous DC and AC coupling up to a combined 13kW of PV. Boosts PV energy 10-20% without increasing PV array size and reduces storage inverter costs up to 30%.
