Operating Instructions

Please read these instructions before use

Basic Wiring With Permanent Load Connection:

Note: 

First start up may take up to one minute.

Settings And Configurations:

Before installation check the position of the switch and adjust the switch to match the battery voltage of 
your system. The switch is located through the hole of the faceplate of the unit. 
For safety reasons this should only be changed whilst the BMPPT has been disconnected from both the 
Panels and the Battery. Preferably before installation
We also suggest the switch be changed gently with a non conductive tool. 

Always ensure that the Switch is set for the Correct Battery Type:

When looking at the unit face on (cable side) with the LEDs at the bottom of the unit:

LEFT position : for 48V batteries
RIGHT position : for 24V batteries
