THE DIFFERENT TYPES OF CONVERTERS
DC/AC converters transform DC battery current to 230 volts 50Hz alternative current. There are also Sine wave converters which provide the same wave form.
They are recommended for sensitive equipment (computer, television.) Pseudosine or trapezoidal converters, much cheaper, are reserved for less sensitive equipment (tools, appliances.)WARNING, LOW RETURN HIGH CONSUMPTION!
A converter does not yield 100%; it averages 85 to 90%. 15% of electricity is, “consumed,” in the conversion. It is better to use the 12v power supply than the 220v for converting. Attention also, to the current con -

FOR INTERIOR AND NAVIGATION LIGHTS
The LED lighting is interesting for lighting inside the boat. It allows great savings without losing light. One may also use it to replace navigation or mooring lights.
Here too the savings will be substantial but always use certified products. Never take chances with safety.THE END OF A BAD REPUTATION
Hoping for huge savings, users flocked to the LEDs. But these bulbs or complete lamps were not suitable for battery operation. The main problem was the supply voltage. The LEDs are very fragile components that do not support surges (which are very violent when starting
