Small Scale Offgrid Solar PV: Installation Manual
Positive and Negative cables connected to the battery together.

Cables
Completely tighten the screws on the battery with a fixed spanner to ensure good connections.
Take care with the ends of cables between the Battery and the Regulator; they are now
live. The negative and positive should never come into contact. If you haven‟t connected to the
Inverter yet, this is also the case with the Inverter cables. When tightening connections to the
battery, always make sure that the metallic tool never touches the opposite pole.
5.1 Terminals for connecting multiple cables to the battery.
The quality of connection to the battery is important to reduce voltage drop and the risk of
over-heating. Crimp connectors are preferable, but some installers use these screw terminals.
In any case, to use the terminals it‟s better to prepare the cables with the same crimp
connectors, instead of merely twisting the bare wire.
