Orientation, Panels, Solar -

  The general notion is that North-facing solar panels (in the Southern Hemisphere) is the most effective way of mounting solar panels. Have you ever considered mounting your panels East & West? Source: solarquotes.com.au   Roof orientation The direction of your panels in relation to the sun, also referred to as the Azimuth angle, is important for the amount of sunshine that your solar panels will receive over the course of the day.   The best way to determine the direction...

MPPT, Panels, Sizing -

  What is a charge controller? A solar charge controller is a regulator for your solar battery that prevents it from overcharging. Batteries are rated for a certain voltage, and exceeding that voltage can lead to permanent battery damage.   Types of solar charge controllers There are two types of charge controllers to consider: Pulse Width Modulation (PWM) controllers and Maximum Power Point Tracking (MPPT) controllers. PWM controllers are generally less expensive and can only be used for smaller systems where the voltage of your solar...

Boats, DC, Galvanic Corrosion, Marine -

Galvanic corrosion is caused by an electric current that enters a boat via the shore power earth wire and returns back to shore via the water. These galvanic currents can cause corrosion to the boat’s underwater metals, like the hull, propeller, shaft and so on. Galvanic current is a DC current and is caused by the natural voltage difference between metals. If a boat with a metal hull is near the shore, a natural voltage difference of 0.1 - 1 Vdc exists between the hull and the water. Galvanic corrosion can be prevented by anodes, galvanic isolators or isolation transformers.
