Key features
Key features of PowerGuard
A power supply layer for equipment that has to keep working where there is no mains connection.
Solar panel integration
Optional solar panel integration charges the battery at remote sites. The panel and charging arrangement are selected for the load and local solar conditions.
Grid free operation
A solar and battery configuration can supply remote locations where a grid connection is unavailable. Load and autonomy are calculated for the site.
More than 24 hours without sun
The documented battery autonomy is more than 24 hours without sunlight. The required duration is checked against the connected load and selected battery configuration.
GSM and GPS monitoring
GSM and GPS monitoring give real time tracking, remote control and location awareness of the powered equipment, from anywhere.
Alarms on critical conditions
The system alerts users during power outages and other critical conditions, so a fault is handled quickly instead of being discovered on a site visit.
Sized for the connected load
Battery and solar requirements are calculated from equipment consumption, seasonal solar conditions and the required duration without charging.
Powers lanterns and sensors
A compact white weatherproof enclosure that clamps to a mast or structure and powers the navigation lantern, day mark or sensor above it.
How it works
How PowerGuard keeps remote equipment running
The battery supplies the equipment, optional solar charging replenishes it, and remote monitoring reports status and alarms.
PowerGuard is the power supply behind other unattended equipment rather than a standalone sensor or display product. In a typical installation, a solar panel and the equipment sit at the top of a mast at the water's edge, and the PowerGuard enclosure is clamped partway down the mast with a short cable run up to the lantern it powers.
The solar panel charges the internal battery, the battery carries the load when there is no sunlight, and GSM and GPS monitoring report status, position and alarms.

Ecosystem
PowerGuard behind Vikingegaarden's AtoN and monitoring equipment
PowerGuard is the off grid power layer for the navigation lanterns, day marks and monitoring sensors Vikingegaarden installs in remote places.
Where there is no mains connection, PowerGuard supplies the equipment and its GSM and GPS link keeps the operator informed. It sits alongside Vikingegaarden's aids to navigation and monitoring products, and its status and alarms are followed remotely to support planned inspection and service visits.
- Powers navigation lanterns and day marks on remote masts
- Powers monitoring sensors and stations without grid access
- Real time tracking, remote control and location awareness over GSM and GPS
- Alarms on power outages and critical conditions

Product guide
PowerGuard: off grid power supply for remote marine equipment
PowerGuard combines an internal battery with optional solar charging for remote navigation lights and monitoring equipment. Load, seasonal solar conditions and service access determine the configuration.
Who PowerGuard is for
PowerGuard is built for equipment that has to work unattended in places with no power infrastructure: a lantern on a channel marker mast, a day mark at a harbor entrance, a monitoring station on a breakwater or a remote stretch of coast. At sites like these, traditional grid power is unavailable or unreliable, and the cost of a failure is not the electricity, it is the dark navigation light or the silent sensor.
PowerGuard is deliberately the power supply layer behind other equipment rather than a product you look at. On site it is a compact white weatherproof enclosure clamped to a mast or structure, with a short cable run up to the lantern or sensor it powers.
Planning autonomy for a remote installation
Start with the equipment load, the solar conditions across the year and the time the equipment must operate without charging. PowerGuard has documented battery autonomy of more than 24 hours, but the required duration is calculated for the selected load and battery configuration.
Nordic winter conditions are part of that assessment. Provide the installation location and operating pattern so Vikingegaarden can size the power configuration and agree the inspection and service plan.
Installation at the water's edge
A typical installation is simple by design. The solar panel and the powered equipment sit at the top of a mast at the water's edge, and the PowerGuard enclosure is clamped partway down the same mast. Mount the enclosure, connect the equipment, connect the panel, and the system takes over: sun charges the battery by day, the battery carries the load at night and in bad weather.
A solar and battery configuration can avoid extending a mains connection to a remote site. Local cables still connect the battery enclosure, solar panel and powered equipment, and mounting is specified for the structure.
Remote monitoring and planned service
GSM and GPS provide remote status, control and location information. PowerGuard alerts users to outages and other critical conditions so staff can assess the issue.
Remote records support planned inspections and service visits. They do not replace the maintenance schedule for the battery, solar panel or connected navigation equipment.
Power budget and operating cost
A remote solar configuration can avoid the cost of extending a grid connection to the site. The actual comparison depends on the cable route, civil work, connected load, inspection intervals, battery replacement and solar conditions.
Solar power has no combustion exhaust at the point of use, but whole-life environmental claims require evidence for panels, batteries, transport and replacement. The project calculation therefore focuses on load, required autonomy, available solar energy and service access.

Frequently asked questions about PowerGuard
What is PowerGuard?
PowerGuard is a power module for remote navigation lights and monitoring equipment. It combines an internal battery, optional solar panel integration, GSM monitoring, GPS and alarms. The configuration is sized for the equipment and location.
Can PowerGuard operate without being connected to the grid?
Yes. PowerGuard supports grid free operation and is ideal for remote areas where traditional power infrastructure is either unavailable or unreliable. It runs on solar power with the internal battery as backup.
How long can PowerGuard operate without sunlight?
The documented battery autonomy is more than 24 hours. The duration required at your site is checked against the connected load, battery configuration and seasonal charging conditions.
What monitoring capabilities does PowerGuard offer?
PowerGuard includes GSM and GPS monitoring for real time tracking and remote control, giving users the flexibility to manage their power system and see where the equipment is from anywhere.
What kind of alerts does PowerGuard provide?
PowerGuard is equipped with an alarm system that alerts users during power outages or other critical conditions, enabling them to respond quickly to system changes or potential issues rather than discovering them on a site visit.
What equipment can PowerGuard power?
PowerGuard is the power supply layer behind unattended equipment such as navigation lights, day marks and monitoring stations. Battery capacity and solar panel wattage options are not published on this page, so contact us with your load and location for sizing.
Is a solar panel required?
Solar panel integration is optional. The battery and charging arrangement are specified around the available power source, connected load and required autonomy. For a site without mains power, solar conditions are included in that assessment.
Where is PowerGuard typically installed?
On masts and structures at the water's edge: channel marker masts, harbor entrances, breakwaters and other remote spots without power infrastructure. The white weatherproof enclosure clamps to the mast, with a short cable run up to the lantern or sensor it powers.
