2.3Wire Size
The wiring and installation methods must conform to all national and local electrical code requirements.
PVWire Size
Since PV array output can vary due to the PV module size, connection method, or sunlight angle, the minimum wire size
can be calculated by the Isc*
modules connected in series, the Isc is equal to Isc of PV modules. When PV modules connected in parallel, the Isc is
equal to the sum of the PV modules'lsc. The Isc of the PV array must not exceed the controllers maximum PV input
current Please refer to the table
NOTE: All PV modules in a given array are assumed to be identical.
* Isc=Short circuit current(amps) Voc= Open circuit voltage
CAUTION: When the PV modules connected in series, the open circuit voltage of the PV array must not exceed
ON-DDB/DDS).
Battery and load wire size
The battery and load wire size must conform to the rated current the reference size as below:
CAUTION: The wire size is only for reference. If there is a long distance between the PV array and the controller
or between the controller and the battery', larger wires can be used to reduce the voltage drop and improve
performance.
CAUTION: For the battery, the recommended
are not connected to any additional
2.4 Mounting
WARNING: Risk of explosion. Never install the controller in a sealed enclose with flooded batteries. Do not install in
a confined area where battery gas can accumulate.
4
WARNING:Risk of electric shock. When wiring the solar modules, the PV array can produce a high open circuit
voltage, so tum off the breaker before wiring and be careful when wiring.
CAUTION: The controller requires at least 150mm of clearance above and below for proper air flow. Ventilation is
highly recommended
