Help!  My Batteries are getting hot!  What should I do?

Victron Energy now have a new iPhone app to help interpret the blinking lights on a Multi-Plus or Quattro inverter/charger

Circuit Breakers vs Fuses, the Presidential Debate. Who to vote for? This short article will look at this debate in the context of two very similar switch panels by Blue Sea Systems. The Blue Sea Systems 4306 WeatherDeck switch panel with fuses is almost identical to the 4376 switch panel with circuit breakers. Which should you choose?

In extreme cases a fuse carrying an excessively high current can vaporize and the metal can be deposited on the base of the fuse block in a way that permits it to continue to carry current. Similarly with circuit breakers, if the level of fault current goes above a certain level the circuit breaker can become inoperable while still conducting current. Fuses and circuit breakers all have an interrupt rating which is a measure of the current that a circuit breaker can safely disconnect in the event of a fault. The interrupt rating may be different for AC and DC and may vary at different voltages..........

The ABYC standards say that a battery switch is required for all DC systems. One of the main reasons is that if a fault such as an electrical fire is discovered the system can be turned off quickly and easily. However certain circuits are exempt from the requirement to be protected by a switch. Do you know which ones?
