Electricity

Voltage and Current

  • High voltages can be harmful to the human body. Use insulated tools when working with electrical conductors.
  • High currents can lead to a fire. Use appropriately sized wiring, clean contacts, and securely clamped connections.
  • Use resettable fuses to protect wiring against excessive currents or to disengage power from wiring that causes issues or needs to undergo maintenance.

OpenDTU-OnBattery is a DIY project, so you are likely to assemble hardware by yourself (to a varying degree). Make sure you understand the possible consequences of errors and accidents when handling solar panels and batteries. Take precautions to prevent injury or damages, like using insulated tools to prevent shocks or short circuits.

For starters, you may want to consult the extensive guide "Wiring Unlimited" by Victron in English or German, which covers the topic of wiring in systems with batteries, charge controllers, and inverters.
