Sol-ark 12k Overview

Limitless

This solar inverter can be used off-grid or on grid and is expandable up to 72 kW! With 20kW peak power, it is truly limitless. Applications include parallel stacking (see video below), grid sell, meter zero, time of use, smart load, AC coupling, & peak shaving.

All-In-One

The Sol-Ark 12k Outdoor Case is a pre-wired system that contains the inverter, charge controller, and more, all in one package; no fuses, breakers, or combiner boxes necessary! With minimal additional hardware required, your install stays simple and low-cost.

Battery Agnostic

Sol-Ark inverters also do not have expensive battery restrictions like other solar inverters do, and can be used with a wide variety of 48V battery chemistries, from lead to lithium.

Highly Accelerated Life Testing

Proven to last well beyond the standard 10 year warranty

Engineered, Serviced, and Tested in the USA

Talk to a US Based Engineer 7 days a week

No Glitch Switch (4ms)

Fastest transfer time in the industry.

The best applications for the Sol-Ark 12k are off-grid, big gains, and time of use. For smaller scale systems, we highly recommend the Sol-ark 8k. Contact us for help figuring out which inverter is right for you!

  • Grid-Tied Mode – Sell power back to the Utility to reduce your electric bill
  • Meter Zero Mode – Zero your electric bill without adding an additional smart meter
  • Time-Of-Use Mode – Use solar and batteries to minimize grid power usage when it’s most expensive
  • Smart Load Mode – Use a programmable output for high-power off grid loads or grid
  • Time-of-use loads – to run only when there is optimum solar – use excess PV power when batteries are full
  • Off Grid applications – battery agnostic
  • AC Coupling – retrofits to existing grid tie systems
  • Battery backup

    Great service and product

  3. Jeremiah –

    Such a powerful & versatile unit. I have been working with Outback, Schneider, Magnum, and various Chinese inverters for years……this rewrites the book and blows them all away. Super impressed and will advise all my premium clients to use this unit. Love Scott and the crew at PP, great service!

  8. Kevin (verified owner) –

    Great Service! Great Products! Thank you

  9. John Bias –

    More expensive than your Chinese inverters BUT for a hassle free one stop shop and unparalleled service this is the inverter to have!!
    This is a set it and forget it type inverter or if you like you can do many intricate things with it. Very Versatile, Compact. No more charge controllers, shunts, inverter, charger. Just one box to do it all.

  10. Chuck Caudill –

    Have been using two 12k Sol Ark’s in parallel for 6 months with 900 AH of batteries. This system is excellent. It does as advertised. The Florida sun coupled with this system produces more than I need which means I make money back almost every month. Practical Preppers is the ONLY place to do business for your solar needs. The support still continues AFTER your system is up and running. I could not be happier!
