Charge controllers with MPP trackers can be used for a wider range of modules
than those without MPPT. With an MPP tracker one is no longer dependent on
the module voltage and string size. The module voltage can deviate signifi-
cantly from the battery voltage.
3.1.4 Notes on choosing suitable solar modules
This solar charge controller has a maximum input voltage of 100 V. If this is
exceeded even for a short time by the connected solar module, the solar charge
controller will be damaged beyond repair and can never be used again. This will
NOT constitute a guarantee claim, the charge controller must then be replaced
at the customer's expense.
The essential value for choosing a solar module is the open circuit voltage
(U_oc). The open circuit voltage of the solar module is dependent on the ambi-
ent temperature. Information on the open circuit voltage of the solar module
and on temperature dependence can be found in the data sheet of the solar
module. The lower the ambient temperature, the higher the open circuit volt-
age of the solar module.
The open circuit voltage at -20 C may not exceed the maximum input voltage.
CAUTION
If an open circuit voltage of more than 100 V is supplied to the connected solar
module, the controller will be destroyed. When selecting the solar module, it
is important to bear in mind that the open circuit voltage should never exceed
100 V over the entire working temperature range.
When using solar modules with a maximum open circuit voltage of between
75 and 100 V (over the entire temperature range), all installation steps must be
carried in accordance with protection class II.
