Description

Overview

The Sol-Ark 12k inverter is the most efficient and cost-effective inverter in its class. This solar inverter can be used off-grid or on grid, is “battery agnostic”, and expandable up to 72 kW! It is truly limitless.

The Sol-Ark 12k 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.

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. When stacked up against equivalent systems, the Sol-Ark 12k is not only the most affordable but also the most efficient and innovative solar inverter on the market!

  • Limitless – Parallel Stacking, Grid Sell, Meter Zero, Time of Use, Smart Load, AC Coupling, Peak Shaving, 20kW Peak Power
  • 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.

Sol-Ark 12k Applications:

  • 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 applications

Sol-Ark 12k Technical Features: 

  • Transformerless inverter
  • Pure sine wave
  • 120/240/208V
  • Grid-tie, off-grid, or hybrid applications (can be with or without batteries)
  • Wide variety or 48V battery chemistries, from lead to lithium

Sol-Ark 12k vs Sol-Ark 8k

The Sol-Ark 12k was released in response to requests for “a Sol-Ark 8k with more power”. Listed below are the updated features found in the Sol-Ark 12k inverter:

  • More Solar PV power (12 kW vs. 8 kW)
  • More Inverter AC power (9.6 kW vs 8 kW)
  • Systems gains capabilities (up to 6 systems gains)
  • 3 phase capability
  • DC breaker
  • Front access points to AC breaker

Most residences will not need to amount of power that the Sol-Ark 12k offers. 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!
