Nauti Tech Transformers


Oct 16, 2018

Few boat owners want to continually have to think about their vessel’s electrical system, especially the power balance between their dual single-phase isolation transformers. Nauti-Tech Systems’ newly released Nauti-Combine safely merges the outputs of two sources into one common, higher-current AC voltage distribution bus. Completely automatic, the result is reliable, even power that stays well below breaker level.

Nauti-Combine works with any two 50- or 100-amp single-phase transformers, even if they have different capacities, e.g., 15 and 25 kVA. Installed in or near the main electrical panel, the compact device can be used with any manufacturer’s transformer, such as Hubbell’s Isolation and Auto-Boost transformers. It can even retrofit a Charles PM3 installation by replacing its internal electronics with Nauti-Boost and Nauti-Combine Kits.

The heart of the Nauti-Combine is its microcontroller. Functionality is completely automatic and shore power problems are detected well before combining. It continually measures voltage and current of both transformers, and intelligently combines and balances the power. If either shore power plug is removed, the unit instantly and safely disconnects to prevent back feed from one plug to the other.

Installation of Nauti-Combine is plug-and-play with minor setup on the included display panel. It’s a Wi-Fi device, so it can be controlled via a smartphone, tablet or PC. It can also be hardwired into an existing network and be connected to the vessel’s monitoring system.

Nauti-Combine is offered in a wide variety of configurations, from a cased electronics-only package to complete setups with switchgear, cables and cabinet.

About a month ago, I traveled to Charlevoix, MI for a special press event to introduce the H9 to a small group of journalists. The water and the weather were a bit cool but the sun was out and Lake Charlevoix was calm and the Four Winns H9 was very impressive. This is a 29-foot 11-inch luxury day boat with a 9- foot 2-inch beam and it features a fabulous expansive flat floor all the way from the bow rider area to the transom and the swim platform.
