Electrical Installation

Electrical parameters such as the Isc, Voc, and Pmax nominal values have deviated from the standard test conditions.
Standard test conditions: irradiance 1000W/m², battery temperature 25℃, atmospheric quality AM1.5.
When irradiance plus normal conditions, the current and voltage values generated may be higher than those obtained under standard test conditions.
Therefore, when determining the controller model associated with the module-rated voltage, wire-rated current, fuse type, and module power output, based on the highest ambient temperature at the installation site, combined with the temperature coefficient of the current in the technical manual, the short-circuit current is multiplied by the coefficient of 1.25 to calculate the short-circuit current.
On the basis of the installation lowest temperature which combining the technical manuals to calculate the open circuit voltage.
The voltages are added up when the modules is in series; current are added up when modules are connected in parallel.
Different electrical characteristics of PV modules cannot series.
It may cause electrical connections mis-match. should be carried out according to the manufacturer’s installation manual.

Connection Type

The maximum number of modules that can be connected in a series string must be calculated according to applicable regulations in such a way that the specified maximum system voltage (According to IEC61730 tests and appraisal, the maximum system voltage is 1000Vdc or 1500Vdc depending on the series and model.) of the modules and all other electrical DC modules will not be exceeded in open circuit operation at the lowest temperature expected at the PV system location. Variation of open-circuit voltage with temperature can be calculated based on the following formula: Voc（T）=Voc(25)×[1-β×(25-T)]. Voc(25) is open-circuit voltage at a standard temperature of 25°C. T is the lowest expected ambient temperature at the system location. Β (%/℃) is the temperature coefficient of the selected module Voc (Refer to the corresponding datasheet).

An appropriately rated over-current protection device must be used when the reverse current could exceed the value of the maximum fuse rating of the modules. An over-current protection device is required for each series string if more than two series strings are connected in parallel;
In the design of the modules, field connections use sealed IP68 junction boxes to provide environmental protection for the wires and their corresponding connections and accessible protection for uninsulated live parts;
The junction box is provided with a connected cable and IP68 connector, which is used for series between modules; Each module has two wires (a positive electrode and a negative electrode) separately connected to the junction box.
The two modules can be connected in series by inserting the positive interface at the other end of the wire of one module into the jack of the negative wire of the adjacent module.
The connection is successful when the clicking sound is heard.

Cable

Field connection modules with cable must meet the maximum short-circuit current, use photovoltaic (pv) systems special light resistant cable.
Recommended to fixed cable by the binding wire resistance to light and line card to fixed on the bracket;
Avoid cable or modules by mechanical forces crushed;
The cable must not be immersed in water for long periods of time.

Connector fabrication and precautions

Connectors

Ensure connector is dry and clean to avoid immersion in water before installation;
Avoid connectors falling on the ground or roof;
A faulty connection may produce electric arcs and shocks;
Ensure check all electrical connections for reliability;
Ensure that all locking connectors are fully locked.

Bypass Diode

The junction box of modules contains a bypass diode connected in parallel to a cell string inside the module;
When hot spots occur in parts of the module, the diode will work, so that the main current will not flow through the hot spot cell, thus limiting the module heat and performance loss;

Note that the bypass diode is not an overcurrent protection device;
