A simple off-grid installation (customer photo)

Making a solar installation is easy. Just 4 components needed: 1) solar panel(s), 2) the solar charge regulator, 3) the battery and the DC/AC inverter.

GWL/Power has supplied the solar panels and the LS1024E PWM regulator.

What is correct: the panels (80Wp small size panels) have the MPPT voltage approx 10V, this means two panels must be in series to get the voltage above the battery voltage (some 15V at max charge).

What is wrong: 1) there is no DC fuse on the battery…. whoops …. always use fusing! 2)shame on the shading: the panels are shaded by the solar cables and also by the battery. This is simply wrong…. the panels will not provide full power potential. Always avoid shading of the panels.

Hint: check this design using the LP battery
