Small Scale Offgrid Solar PV: Installation Manual
Rules for safe battery installation.
Use thick cable for link connections between the batteries (#2 AWG gauge.)
The terminals for these links must be very well done, with no bare cable visible.
Tighten the screws of the battery terminals according to the torque recommended by
manufacturers.
The main positive and negative cables should be the same length and should be
connected to opposite sides of the bank of batteries. This is to create an equal path
length for the flow of electrons.
Draw a diagram of the connections.
Never mix batteries of different types
Never measure battery current across terminals
Use the right size fuse if it is necessary to have a fuse. It should be installed in main
positive battery cable.
Remove jewellery before starting work.
Use the right tools. It‟s better to work with insulated tools.
Disconnect any battery charger or electrical load before working
Use goggles to protect your eyes and wash your hands immediately after working.
