STANDARD INSTALLATION MANUAL FOR POLARIS 580W (HOOP INSTALLATION)
● The maximum quantity of single-string products that can be connected in series must be
calculated according to the requirements of the relevant regulations. The value of the open-
circuit voltage at the expected minimum local temperature conditions must not exceed the
value of the maximum system voltage specied for the product (the maximum system voltage
for the product is DC1500V - the actual system voltage is designed according to the selection
of the product model and inveer) and the value required for other DC electrical components.
● The open circuit voltage correction factor can be calculated according to the following
formula: CVoc=1-βVoc×(25-T). T is the minimum expected ambient temperature at the system
installation location and β(% /° C) is the temperature coecient of the selected product Voc
(refer to the corresponding product data sheet).
● If a reverse current exceeding the maximum fuse current of the product may pass through
the product, an overcurrent protection device of the same size must be used to protect the
product. If the number of parallel connections is greater than or equal to 2 strings, there must
be an overcurrent protection device on each string.
6.2 CABLE AND CONNECTION WIRE
● The Polaris series should be connected by using IP68 rated junction boxes, which should
provide safe protection for the conductors and their corresponding connections and accessible
protection for non-insulated live pas. The junction box consists of a connected cable and IP68
rated connectors to facilitate series connection between products. A single product has two
separate wires connected to the junction box, one positive and one negative. The two products
can be connected in series by inseing the positive connector into the socket of the negative
lead of the adjacent product.
● Use dedicated solar cables and appropriate connectors (wires should be encased in age-
resistant conduit or, if exposed to air, they should be age-resistant themselves) and ensure that
the cables are electrically and mechanically sound, in accordance with local re, building and
electrical codes.
Installers need to use a single-core PV-specic cable with appropriate insulation to withstand
the maximum open-circuit voltage (as approved by EN 50618). Appropriate wire sizes need to
be selected to reduce the voltage drop.
● All wiring and electrical connections meet the requirements of the appropriate National
Electrical Code. When xing the cable to cable bracket, avoid mechanical damage to the cable
or the product. Do not squeeze the cable by force. The cable must be xed to the bracket by
specially designed aging resistant cable ties and cable clips. Although the cable is resistant to
aging and water, it should be protected from direct sunlight and rain.
The minimum bend radius of the cable should be 43mm.
