4.2 Solar PV connections

REhub accepts input voltages between 0V to 90V. It can start charging the batteries when

the input voltage is above the battery voltage. Keep the connection ready. Close the

connections when you are ready to POWER Up.

4.2.1 Serial connection of Solar PV string

must be strictly followed.

To get the optimum Voltage, the solar modules shall be connected in series to form a

string having the desired voltage. The optimum operating voltage of the module string

(Vmpp) must always be above the battery Voltage.

To establish the minimum number of PV modules to be connected in series in the same

string, the max voltage of the battery must be multiplied by 1.1 and divided by the

modules Vmpp voltage.

For example, for a 24V system with a lead-acid battery with maximum Voltage of 30 V

and using PV panels with 17V Vmpp. 30*1.1/17=1.94.

The result must be rounded up to the higher value (i.e. 2 modules - of 17 Vmpp - in series

for the above example is the MINIMUM number of panels required for operation).

4.2.2 Maximum Panels in Series

The open-circuit voltage of the string must be lower than 90V under any temperature and

irradiation conditions.

To establish the maximum numbers of the PV modules connected in series in the

same string, use the following formula: 90V/(Voc). (Example: 90/(22)=4.09). The result

must be rounded down to the lower value (i.e. 4 modules - of 22 Voc - in series for the

above example).

There can be thus 4 PV modules in series of the mentioned model for a 24V system as per

this example.

Table 4 gives an idea of the possible arrangements for common panels according to the

number of cells or their type.

Note that CIS or other forms of THIN film PV modules cannot be connected to REhub

unless their Voc is <90V.
