A solar powered upright freezer is a great way to save money and energy. Although it is not yet widely available, there are a number of models that can be powered by solar panels. These units come in a variety of shapes and designs. Some freezers use only a hundred watts of power, while others require a thousand. However, it is not easy to determine which is the best choice. It depends on the size of your freezer, the type of batteries you want to use and the number of sun hours you can expect to have.
The best way to figure out whether your freezer will run on solar power is to calculate the number of sun hours you can expect. If you have a larger freezer, you will need more than a thousand watts of power. For a medium-sized one, you will need at least ten to twenty panels.
Assuming you're living in an area with a reasonable amount of sun, you should be able to generate about three to five hours of power per day with a 100-watt panel. That's not a lot, but it is enough to keep a portable freezer running for a few hours. Depending on the type of battery you choose, you may need a charger to maintain the voltage.
In addition to a suitable charge controller, you'll also need a good-quality inverter to convert the DC into AC. This will help ensure you get the right voltage, as well as protect your batteries from overcharging. You'll also need a battery that can hold at least a few hundred watt-hours of power. Ideally, you'll need to have two or more batteries to support your freezer.
While there are some models that can run on AC alone, most require an inverter and batteries. Since it is difficult to predict how long your solar power will last, it is better to go with a system that includes a battery backup.
If you are planning to run a large or deep freezer, you'll need a system that can provide a consistent power source. Your solar power panel and battery will need to be situated at a proper distance from each other. Whether you are using a portable or deep freezer, the battery should be kept half-full at all times.
If you plan to use a solar freezer for more than a few days, you'll need a battery to hold at least a few hundred watt-hours. Smaller models can handle that amount, but for a deep freezer, you will need something with a larger capacity. Larger batteries can support a greater number of watt-hours, which makes them ideal for longer-term storage.
The solar power freezer is an ideal option for anyone who wants to save money and energy, but it is important to consider the details. When choosing your equipment, be sure to make a careful calculation of all the factors, as well as use the most appropriate components.
