We must first focus on maintaining photovoltaic equipment rather than the issue of generation of energy as winter approaches. Winter draws near. As we prepare for the coming of winter, we must first note the following:
Array inspection, conducting wire and coupling bots need to be fastened, test output and adjust inclined angle.
The tracker bearing should be lubricated and the shock-absorber bolt should be inspected.
Inspect the equipment to be certain it is in good condition, confirm the wire connection, and use the standby fuel system if it's available.
Verify your charging controller, your rectifier's setting, and your voltmeter is functioning normally. For a 12 volt system, charging should be allowed as long as the battery temperature is below 55°F (12.778°C). Temperature compensation is automatically handled by the charge controller if it has it. Ensure that any external temperature sensors are attached to the battery, if there is one. When automatic voltage adjustment is not available, the voltage must be manually increased and then adjusted back in the spring (to 14.3 volts). The battery should be kept in an environment that is warming if the charge controller cannot be adjusted.
The battery (lead acid), measure the voltage, determine if the charged batteries must be balanced, and eliminate the disabled batteries. In order to maintain balance charge, or moderate overcharge, the battery needs to be charged for 8 hours after it has fully recharged. (Neutralize the acidic precipitate by washing the liquid or dust off). To prevent further corrosion, clean or replace corroded terminals. There can also be a paraffinum liquidum applied to prevent corrosion. Battery fluid should be checked daily and deionized or distilled water if needed. The air ducts need to be checked for insects and other intrusive organisms. Make sure the wiring is the correct size, that the connections are secure, and that the fuses are working. If lightning protection is needed, grounding posts or grounding wires should be installed.
Invisible loads and inefficient applications can be caused by loads or electric appliances. Whenever the electricity is turned on, wall-mounted transformers and TVs with remote controls consume power. Make sure the inverter is working all day long on your electric heater if it is automatically tempered. Blackened incandescent lamps may be replaced by halogen or fluorescent versions. Replace the fluorescent tube black with a halogen lamp. Wipe off the mounting bracket and the light.
Check the regulator, the installation setting, and the wiring of the solar inverter. It is recommended that the inverter's charging voltage be set at 14.5 (29) volts. The instruction manual provides more information regarding how to do this.
Among lead-acid batteries, temperature loss is 25% at 30 °F. Getting fully changed at 20 degrees will cause it to freeze. Summer overheating can also damage its life span. Hence, a battery should not be exposed to high outdoor temperatures.
