Multiply all voltage values by a factor of 2, 3 or 4 for respectively 24V, 36V and 48V systems
When different charge program parameters are desired, the Custom (USE) battery type can be
selected. For further parameter explanations or info on how to create a Custom charge program,
please download the Omnicharge Solar user manual from our website.
!
CAUTION
Invalid battery type settings can cause serious damage to your batteries and/or connected
battery loads. Always consult your battery’s documentation for the correct charge voltage
settings.
3.2 Battery type selection and solar charger reset
The battery type can be changed in three ways. This can be done using the setup button inside the
connection compartment of the solar charger, by using the control display on the front panel or by
using the TBS Dashboard Mobile app. In this installation manual we will only explain the setup
button method. The two other methods will be explained in the Omnicharge Solar user manual that
can be downloaded from our website.
