The Best Solar Inverter Just Got Even Better.

Limitless Power meets Limitless Support

Unbound Solar and Sol-Ark have teamed up to deliver an unprecedented energy production experience — combining the best-in-class inverter with the #1 solar support team in the USA.

What Makes Sol-Ark the Best Inverter for
Grid-Tie and Off-Grid Solar?

Easy Installation

Sol-Ark’s all-in-one, compact design takes the headache out of your inverter hookup:

  • Weighs only 74 lbs. — 3x less than legacy systems
  • Easily accessible terminals for quick adjustments
  • Fewer components & small parts

Adaptive Technology

Sol-Ark offers out-of-the-box integration with grid-tie, off-grid, hybrid, and battery backup systems:

  • Uninterrupted backup power
  • Compatible with a wide range of lithium and lead-acid battery manufacturers
  • Supports peak demand shaving

Storage-Ready Design

The Sol-Ark can function as a grid-tie inverter — with or without batteries. Add energy storage right away, or wait until later when the time is right for you.

Effortless Expansion

Sol-Ark is great for projects both big and small. With the ability to parallel stack up to 9 inverters, Sol-Ark can adapt to larger applications and varying power demands.

Flexible Mounting Options

Install your Sol-Ark in a location that’s most convenient for you. The Dual 500Vdc PV Chargers with 1-6 PV string inputs mitigates performance issues and extra installation costs associated with long-distance wire runs.

Better Battery Life

Maximize your batteries’ lifespan with a built-in auto-generator start for your AC generator that keeps batteries at an optimal state of charge 24/7.

Monitor Anywhere, Anytime

Wi-fi connectivity allows you to monitor your system performance both on-site and remotely using the Powerview App.

Class-Leading Efficiency:

Get more power from your panels, and use it whenever you need it. Sol-Ark maximizes production from your system with minimal energy losses and low self-consumption.
