Generators and Solar

Energy independence is the central issue of every cruising voyage. Whether you are adding solar panels to keep your house batteries charged or evaluating a portable generator for peak load demands, the principle stays the same: always calculate your daily amp-hour consumption before buying. An undersized solar system or a generator not matched to your specific load can easily result in wasted investment or prematurely sulfated batteries.

Our technical approach focuses on component validation. On deck or in the engine room, every bit of space is precious and every connection must stand up to salt corrosion. For this reason, we prioritize charge controllers with IP67 protection and AISI 316 stainless steel mounting hardware, avoiding solutions that do not offer genuine durability in a marine environment. If you have questions about compatibility between your existing battery bank and your charging system, contact us for a technical consultation before you order.

The choice between a silenced gasoline generator and a photovoltaic system depends on your boating profile: short weekend outings call for a different approach than long offshore passages under complete autonomy. At Nautiba we provide clear visibility on stock levels and delivery times, so you can focus on the technical installation rather than managing logistics delays.

Sizing Your Onboard Power System

Component selection must follow precise technical criteria, avoiding unnecessary oversizing or undersizing that shortens battery service life.

• Calculate your total daily consumption in Ah and compare it with the peak output of your solar panel expressed in W.
• Check the IP rating of charge controllers when they are installed in wet or splash-prone areas.
• Make sure the portable generator has a rated power output adequate for the continuous load you plan to run.
• Use cable cross-sections sized to minimize voltage drop, especially over long runs between panels and controller.

How do I calculate how many solar panels I need?

Add up the amp draw of every device you run in a typical day and multiply by the hours of use. Divide the total by the effective peak sun hours in your cruising area, then add a 20% margin to account for system efficiency losses.

Is a gasoline generator or a solar system the better choice?

A generator is useful when you need to power heavy loads such as air conditioning or an induction cooktop. A solar system is optimal for steady battery maintenance without any noise, making it the right choice for relaxed cruising at anchor.

Is an IP67 rating essential for external components?

In a salt environment, electronics without IP67 certification or better will oxidize quickly, compromising electrical continuity and the safety of the entire system.
