How to Set-up a Solar Power System in the Philippines?
1. Search for a best location/area where there's plenty of sunlight. As much as possible, no shadows from trees, buildings, etc. This is how I've installed my 140-watt solar panel in our backyard:
CD-R King 140-watt Solar Panel Specifications
The slotted angle bar is bought as a whole 12-feet. I cut it to pieces according to the needed sizes fit for the aluminum solar panel frame. The slotted angle bars are attached through bolts (bolts for slotted angle bars) to the aluminum frame of the solar panel.
The metal stand I use for my solar panel is an old retractable canopy frame. I'm just using a tie wire to hold the slotted angle bar to the retractable canopy frame stand.
I'm using two separate THHN/THWN 3.8mm² 12/7 wire. One wire for the positive line (color yellow) and the other is for the negative line (color black).
The junction box of this solar panel has a built-in two diodes inside. Diodes protects the solar panel by blocking the current from going back to the solar panel.
Solar Panel Junction Box
It allows the current to flow in just one direction (from the solar panel going to the Solar Charger Controller to the Battery). Without diodes, current from the battery will go back to the solar panel that causes the solar panel to burn or heat-up, thus, damaging the solar panel.
The MC4 cable wires of the solar panel are soldered and connected to the THHN/THWN 3.8mm² 12/7 wires (connected positive to positive and negative to negative).
2. Connect the THHN/THWN 3.8mm² 12/7 wires to the Solar Charger Controller (connected positive to positive and negative to negative). Observe the same polarity. Take a close up look to my Solar Charger Controller.
CD-R King Solar Charger Controller (CM5024Z)
I'm a using a recycled PDX solid wire (color white) for connecting from the THHN/THWN 3.8mm² 12/7 wires (that connects to the Solar Panel) to the Solar Charger Controller. This Solar Charger Controller has 3 pairs for terminals. One pair for solar panel. One pair for Battery. And one pair for Load. Take note of the polarity of the terminals. Positive and negative. Always observe same polarity. What you see on the small screen of the solar charger controller is the voltage reading of the battery (12.9 Volts). It will reach to full battery if it reads 14.2 Volts, it will automatically disconnect the current from solar panel to the battery. If it reaches to its minimum battery capacity (11 volts), it will disconnect the current from the battery to the load. Thus, avoiding overcharging and overdischarging. If it reaches 12 volts, it will connect the solar panel to the battery in order to charge the battery. It it reaches 12.6 volts it will automatically connect the battery to the load. This is how I set-up the automated connection and disconnection system of the solar charger controller. You can manually set-up your own minimum or maximum voltage connection and disconnection system. You can read its manual for more information about the solar charger controller.
3. Connect the Solar Charger Controller to the Battery and Load. Observe same polarity (connect positive to positive and negative to negative).
Solar Accessories Set-up: Solar Charger Controller, Battery, Power Inverter
Take note of the wiring set-up. The Power Inverter is directly connected to the Load Terminal of the Solar Charger Controller and not to the Battery.
To use this solar-powered set-up, just plug any 220-volt AC electrical device or appliances (having 500-watts or below) to the Power Inverter. Make sure the device (load) should be within the range of 500-watts or below. Do not plug any device greater than the capacity of the power inverter or else the inverter will be oveloaded that can destroy the inverter.
