Solar monitoring power supply system installation precautions.
1. Solar panel orientation: Install the solar panel according to the actual position of the sun to ensure maximum solar efficiency.
2. Solar panel photovoltaic bracket, distribution box hoop must be in front of the hoop with anti-slip pad, to prevent the wind to change the direction of the solar panel.
3. Before installing the solar panel, it is necessary to have a single solar positive and negative electrode connected to reverse, and have no output voltage (test tool: multimeter). Test method, the solar panel is placed outdoors with a multimeter to measure the voltage above 18V normal. Solar panel outgoing red, black and negative, test positive and negative electrode welding), prevent transportation jitter, virtual welding to reduce defective rate.
4. Install the power supply system in the correct sequence: connect the battery first, then the solar panel, then turn on the load. Later maintenance is just the opposite order. First turn off the load, then turn off the solar panel, and finally turn off the battery.
5. Equipment prior to installation check box controller have LCD display, battery voltage is above 26 v, LCD controller if there is no display, display voltmeter is no batteries, battery is low voltage into a state of protection (equipment placed for a long time can cause), to activate the battery, connected to solar panels or lithium iron battery chargers for direct access to the controller, The controller will start the activation process, see the battery voltage rise to 26V above the normal installation.
