Think of our system as a “choose your own adventure” climate machine. Instead of locking you into a single BTU rating, you get three selectable modes — 5k, 9k, and 12k BTU — all built into a single smart package. You decide how much cooling power you want based on the size of your cabin, the heat load, and how much battery you want to use.

Our customers use it everywhere: from cuddy cabins on 27-foot center consoles to primary suites on 75-foot motoryachts. Even in surprisingly large cabins, 9k BTU mode provides excellent long-duration cooling and heating. You’re in control of the experience — and that’s what makes it fun.

Absolutely not. The entire point of this system is to ditch the noise, smell, and hassle of a generator. Our DC-powered platform was born from real cruising experience — long nights at anchor, quiet coves, and wanting to actually hear the ocean instead of an engine.

With the right battery bank and solar setup (we’ll guide you on that below), the system can run entirely off-grid. On sunny days, many boaters run directly off solar alone.

LifePO₄ banks perform best, but large AGM banks can also get the job done.

Nope! Our climate system is the perfect “don’t let me overdo it” cruising companion. You simply tell the system how many amp-hours you want it to use — say, 200Ah — and it will run normally until it reaches your budget. Once it has consumed that amount, it shuts down so you always stay within your energy plan.

It’s a boater’s dream: peace of mind without constant math.

We always say get as many as you can - battery prices have dropped significantly in recent years, making it more affordable to invest in additional capacity. That said, you can run our machine overnight in the heat of the Florida Keys and use **less than 300Ah** in 9k BTU mode over about 12 hours. We've personally done this and many of our customers have reported similar performance aboard their boats.

If you have a decent solar array, even better — your batteries will recharge throughout the day while you stay cool.

As with batteries, get as much as you can. More solar means more power on cloudy days and during winter months. A properly sized MPPT controller and higher-voltage panel strings dramatically improve real-world performance — especially in partial sun or tricky shading situations.

In strong sun, many boaters run daytime cooling directly from solar. That’s the magic of DC climate done right. Many customers with 1000+ watt arrays have reported charging while also running the AC.

Solar isn't required, however. Motor vessels with inboard diesels and also cabin cruisers with outboard motors will also run our machines effectively. The power output from alternators can charge the house bank and surplus can be used to run the AC.

Yes! Many customers — especially catamaran owners — split air between two cabins. A simple Y or T duct fitting lets you send air to two separate spaces such as a salon and a lower cabin.

Airflow is divided between both vents, so it won’t blow as strong as sending everything to one location. The return air also won't be pulled from both cabins so performance may not be optimal, but it can work well enough to be viable and dramatically improve comfort, especially overnight when sleeping. You can also set up ducting with dampers to close off one side when not needed.

Call or text us. These machines were designed through our lived experience on the water. We're happy to share what we've learned along the way and can offer opinions on solar setup, battery configuration, system installation - really anything you can dream up. We've outfitted cabin cruisers, sailboats, catamarans (sail and power), motor yachts, speed boats, and many other types of vessels.

Let us know how we can help.
