Sol-Ark 15k

The Sol-Ark 15k Outdoor Case inverter has an entirely new range of use than its sister Sol-Ark 12k inverter. This all-in-one pre-wired inverter system features new capabilities and is the most efficient and cost-effective inverter in its class by a long stretch.


This solar inverter can be used off-grid or on grid! Applications include parallel stacking (see video below), grid sell, meter zero, time of use, smart load, AC coupling, & peak shaving.


The Sol-Ark 15k 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

The best applications for the Sol-Ark 15k are off-grid, big gains, and time of use. For smaller scale systems, we highly recommend the Sol-ark 12k.

  • 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
