East & West is Best!? Solar Panel Orientation
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...
How to size your MPPT Solar Charge Controller?
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...
Don't sink your boat! Galvanic corrosion
ANL, MEGA, CNN, MIDI? DC Fuses - what to use where?
What is a Fuse?First of all, let's try to understand what is fuse is for. A fuse is an electrical safety device; it protects an electrical circuit against high currents. The fuse is placed in the supply cable to an electrical device. If a current flows through the fuse that is higher than its rating, the fuse will blow, and no more current will flow. This is what the fuse is supposed to do, to protect the device. Whatever the issue...
