Solar system for boat – 120W with MPPT charge controller

Stable power for everyday use on board

This solar system is a reliable choice for those who want more freedom in the harbor and at anchor - without constant dependence on shore power.

In good sunshine, the system can produce up to approximately 480 Wh per day , which can keep the boat's basic consumption running for several days at a time.

The system is suitable for general consumption on board, such as:

• Cabin lights, navigation lights and anchor lights

• Radio and small electronics

• Computer and mobile phone charging

• TV (limited use)

⚠️ Important to know
If you have a compressor-driven refrigerator , the system will not be able to keep the battery fully charged for a long time. In these cases, the battery will gradually discharge day by day. For boats with a refrigerator, a larger system is recommended - I will be happy to help you find the right solution.

Efficient MPPT technology – more energy from the sun

The system comes with the latest high-end MPPT charge controller , which ensures maximum utilization of the solar panel.

✔ The panel operates at optimal voltage (approx. 18–19V)
✔ Up to 35% higher yield compared to traditional PWM chargers
✔ Compatible with both lead and lithium batteries
✔ Built-in display for easy monitoring

Shadow optimization – flexible solution for the boat environment

Shadow from mast, boom or sails can affect solar production.
If you choose the solution with 2 x 60W panels , each panel will work independently. This means that you will still get power even if one panel is temporarily in the shade.

Suitable for marine environments

All solar panels in the package are:

• UV-resistant

• Resistant to salt corrosion

• Suitable for permanent installation on board

Recommended battery size

For approximately 2 days of consumption without sun, we recommend:

• 12V / 150Ah battery (approx. 1800 Wh)

• Preferably a gel or deep-cycle solar battery

The package contains

• 120W / 12V BLACK mono solar panel
  (alternatively 2 x 60W panels)

• MPPT charge controller 12V–24V / 20A with display (and lithium support)

• UV-resistant cables (2 x 5 m)

• Waterproof MC4 connectors

• 3 m battery cable (2.5 mm²) with 30A fuse

• Connection instructions

Assembly & extensions

🔧 Mounting brackets are not included as boats vary in construction.
