Connection with solar panels

According to the solar street light system voltage and voltage solar modules will cable connected solar modules. If the solar LED street lamp system voltage is 24 v, the voltage for the solar cell components or 18 v, 17 v, in tandem solar cell components should series method is the first piece of component is level ( Or negative) And the second component of the cathode ( Or is level) The connection. If the voltage of the solar cell component is 34 v, can deal with solar battery components in parallel, the parallel method is the first component of positive and negative electrode and a second piece of component of positive and negative corresponding connection. Connection with a small screwdriver with open when the solar cell component junction box, pressed the solar cell component of the power cord to the junction box of the terminals, require the red line is level, the blue line after the cathode. Line connected after the junction box for the waterproof nut fastening, and the terminal box terminals with 7091 seal of silica gel, glue amount to make the terminal box into line hole is completely sealed. Then buckle on the junction box cover, junction box cover should fasten, not against.
the multimeter testing solar energy battery components of attachment ( Answer the controller side) Not with short circuit testing solar modules output voltage whether conform to the requirements of the system, in fine weather should be greater than its open circuit voltage 18 v ( System voltage is 12 v) 34 v (or System voltage is 24 v) 。 Before installation and testing, for the solar cell component power cords to the controller the positive application of insulating tape will be exposed wire core, insulating tape package two layers; Solar energy battery components during the installation process should take put down gently, avoid instrument such as damage to it.
solar energy battery components and bracket with M6 * 20 bolts, M6 nut, washer fastening. When installation, it should be installed in the bolt by outgoing, then set the washer and nut fastening. Request when fastening bolt joint connection is firm, no loose.
solar street lamps factory introduction after wiring, toward the sun solar cell components, the multimeter test power output correct negative polarity is correct, whether the open circuit voltage within a reasonable range. System voltage is 12 v, open circuit voltage value should be within the scope of 18 to 23 v ( Sunny day) System voltage for 24 v, open circuit voltage value should be within the scope of 35 to 45 v ( Sunny day) , open circuit voltage in the reasonable scope may carry on the next steps, or testing each piece of solar modules output is normal and wiring is correct, until it is correct.
