Solar panels & controllers

Stabilize your onboard power system with a systematic approach

Voltage, power, and battery type must be matched for your system to remain stable.

The sizing of cables and fuses is also important for safe and efficient operation.

This ensures your onboard electrical system runs reliably – from start to anchorage.

Discover variants, materials, and designs built for maritime use. This way, you'll find equipment that remains reliable onboard – season after season.

Deine Fragen / Unsere Antworte

What type of controller do I need for a lithium onboard electrical system?
You need a controller that explicitly supports lithium profiles (LiFePO4) and allows you to set the charge termination and float voltage accordingly. Many standard PWM controllers are not suitable for this.
Can I glue a semi-flexible module directly onto the cabin roof?
In principle, yes, but make sure the surface is absolutely clean and load-bearing. Semi-flexible modules still need some air circulation on the underside, otherwise, the internal temperature will rise and performance will noticeably decrease.
How much module power do I need to keep my anchoring equipment balanced?
That depends on your daily consumption – first, determine how many Ah you use per day, and then plan the module so that it covers this demand on a normal sunny day. As a rough rule of thumb: it's better not to underestimate your consumption.
What cable cross-section should I use between the module and the controller?
You calculate the cross-section from the module's maximum current and the cable length. Cables that are too thin mean voltage drop and heat loss – when in doubt, choose a larger size and use marine-certified MC4 connectors for all outdoor connections.
