Sol-Ark 12k: The Ultimate Solar Inverter

At Practical Preppers®, we’ve been designing and installing solar systems for many years. Ever since Sol-Ark began releasing inverters, we have exclusively used and recommended them for solar installations. Here, we have outlined the prominent features of the new Sol-Ark 12k and why its a great solution for our off-grid customers.

Powerful

The Sol-Ark 12k can take up to 16kW of PV power and outputs 12kW of continuous power. This solar inverter is a combined output, so the power is distributed simultaneously to your battery bank, AC loads, and to the grid for sell-back. Up to 9.6 kW can be directed to the grid/AC loads, while the remaining power is used to charge batteries that you may have. 

Additionally, the Sol-Ark 12k has gains capabilities, up to 6 systems (72kw)! Providing you with true 208 power with 3 inverters. This is great news for people interested in commercial solar. 

Most residences typically do not need the amount of power the 12k can provide, but it is perfect for off-grid and big gains systems.

What the Sol-Ark 12k has in power, it does NOT lack in efficiency. The Sol-Ark 12k has 96% on grid PV to AC efficiency! This is top-rated efficiency that saves you money in the long run. See our comparison charts below

All-in-one

Perhaps our favorite characteristic of Sol-Ark inverters is that is an all-in-one smart system. The Sol-Ark 12k is a pre-wired system that requires no fuses, combiners, or breakers, keeping your installation simple and low-cost. Listed below are the things that are INCLUDED in one Sol-ark 12k inverter. 

  • Two built-in 500v Charge Controllers
  • Battery Disconnect
  • 48V Battery Input
  • Battery Sensor
  • Auto-Generator Start
  • Rapid Shut Down Signal
  • Current Sensors
  • Battery Communication
  • PV Disconnect
  • Wiring Knockouts and WiFi
  • 50A AC Breakers with convenient front access points 

With other inverters, you would have to spend thousands of dollars on additional hardware (most of it being required) to reach the equivalent of one Sol-Ark. The color touch screen interface and remote monitoring is also a bonus. Our customers love how easy it is to interact with the Sol-Ark inverters. 

Flexibile

The Sol-Ark 12k can be used on grid-tie, hybrid, and off-grid systems. This means you can install the Sol-Ark for a grid-tie system and have the option to easily add a battery back-up when you are ready. If you already have an existing grid-tie system, you can AC Couple the Sol-Ark 12k and retrofit it to a battery bank.

Unlike most other inverters, the flexible Sol-Ark is not limited to a single type of battery. We informally call this being “battery agnostic”. The Sol-Ark 12k inverter works with the widest variety of 48V battery chemistries, from lead to lithium ion. 

And as mentioned before, the Sol-Ark 12k is expandable up to 6 systems gains. Your options and applications are limitless!

Proven and tested

This inverter is engineered, tested, and serviced in the USA, and has been proven to last well beyond the standard 10 year warranty. 

All Sol-Ark inverters have an option to add Solar Flare / EMP protection. Read full details in the specifications below
