Turnkey Kit for installing and providing correct power for a Starlink RV/Residential kit onboard a boat.
Narwhal Starlink Install Kit
This is a complete kit to install a dedicated inverter to power and control a Starlink system onboard a boat. No need to hack/modify the Starlink system and works with Starlink Residential, Business, and RV units.
- Dedicated Pure Sine Inverter for Starlink (12VDC input, 120VAC output)
- Bluetooth adapter for Inverter
- DC Battery Cables (15ft)
- Chassis Ground cable (15ft)
- 80 Amp fuse and holder
- 25ft Cat 6 Ethernet cable for Starlink interconnection to onboard 3rd party router
- Panel mount on/off switch for Starlink/Inverter system with 25ft of wire
Inverter is a Victron model and can be integrated with onboard Victron GX monitoring equipment. Let us know if you would like to replace the Bluetooth module in the kit with a VE.Direct cable to connect to a GX device.
For your safety, Sea-Tech recommends that Inverters be properly bonded (Neutral-to-Ground) at the Inverter itself. Sea-Tech Starlink Power kits are shipped with the Inverter’s internal bond already established so you don’t need to perform this change yourself.
Customer must supply battery terminals for DC cables to match their vessels connection needs.
Starlink Ethernet Adapter is not included, and must be ordered from the Starlink Shop directly. Ethernet Adapter is only needed if connecting Starlink to a 3rd party router or network (such as one of our Narwhal systems).
Powering Starlink on board
Starlink Power Supply Notes:
Whole-vessel Inverter/Charger vs. Dedicated Inverter(recommended)
Starlink hardware has a few nuances that make a dedicated inverter the
preferred option for providing power in a boat.
1.) Starlink doesn’t have a power switch. It’s always on if plugged into AC
power. When using a whole-boat Inverter/Charger circuit, this means any
time the boat’s Inverter is on, Starlink will be on and consuming power, and
there is no way to turn Starlink on without also supplying power to other
AC loads that you may not want to power up. Having a dedicated inverter
with it’s own switch allows for Starlink to be turned on and off as needed
without affecting the rest of the AC circuits in the boat.
2.) Starlink hardware is sensitive to power outages and brownouts. Multiple
small power outages can and will cause the system to reset to factory
defaults all by itself. This has been seen on multiple boats where a whole-
boat inverter was passing through shore power, and when shore power
blipped a few times, just switching between Shore and Inverter automatically
caused a factory reset.
3.) Starlink does not like dirty and/or modified sine-wave AC power. Pure
Sine Wave Inverters are highly recommended. Some whole-vessel Inverter
units may be modified sine-wave, particularly if they are older.
Notes on Powering directly from DC Power.
Starlink equipment uses a high-amperage, non-standard, Power-Over-
Ethernet (POE) solution along with proprietary cable connections. While it
is possible to modify the cable, integrate a custom POE power supply, and
eliminate the standard Starlink power supply/router unit entirely, hence
powering the system from DC without using an Inverter, we do not
recommend this approach as it is inherently unsupportable, voids any
warranty, and is not 100% reliable in practice. There are many ways that
the custom DC solution can fail.. It is for experts only and only for those
willing to accept that they could destroy their Starlink equipment. These
issues are why we recommend the Inverter-based solution.
The “Starlink Ethernet Adapter” available from Starlink.com Shop. You can order it as an accessory once you’ve placed your full Starlink kit order
