Start Using Solar UPS System and Save Energy
Energy demand is increasing at a fast pace all around the world and if not controlled it would lead to energy shortage. A solar energy system is a perfect way to reduce the day to day uses of electricity and when it comes to using solar energy whether it’s for household or commercial purposes, solar UPS is one of the most important components of the solar electric circuit.
UPS is a helpful device that converts Direct Current (DC) into Alternating Current (AC). Amidst blackouts and different sorts of energy crises, the UPS is brought into play. UPSs can be utilized to run a wide range of family unit apparatus like TV, Microwave, Washing Machine, PC, Printers, and different power instruments, along with different sorts of gadgets as well.
A UPS should be controlled with a 24V or 12V battery. Truth be told, the UPS batteries additionally should be charged after a specific timeframe. The battery reviving can possibly be utilizing Solar Panels as it could be charged after a specific time frame.
Difference between a UPS and an inverter:
Individuals essentially surmise that UPS and Inverter both are contending ideas. Indeed, the prime thing is that an inverter fills in as a converter to change DC into AC, though a UPS is hardware which gives uninterruptible power supply and if there should arise an occurrence of energy disappointment, it enables a prompt change to the power reinforcement source and in this way, it guarantees constant power reinforcement to the basic device like a PC.
Be that as it may, there is as yet an inquiry by the purchasers i.e. at the point when a laptop battery is giving guaranteed constant power supply, at that point what is the need of a UPS. All things considered, in the event that you need a constant and continuous internet connection, you likewise require your switch and modem running ceaselessly.
How to choose the Right Solar UPS?
We live in a region where power cuts are frequent happenings. Thus, buying a Solar UPS has become inevitable for us. Before buying one you need to do the basic research to decide which one to buy. Here, Industrybuying is sharing a buying guide over the same so that it can help the buyers.
Following points are needed to be considered while buying right Solar UPS:
Type of UPS available in the market
UPS is basically of two types:
- Pure Sine wave
- Modified Sine Wave.
These two types differ from each other. The main difference relates to the properties of generated waveform when the UPS changes DC into AC.
When providing power to different home appliances, pure sine wave UPSs make for better accuracy along with a high-end circuitry.
Pure Sine Wave Solar UPSs are used for some appliances like heaters, toasters, medical equipment, induction motors; electronic timing devices switch mode battery chargers, sensitive scientific research appliances, laser printers, variable speed motors, digital clocks and some kinds of timer gadgets.
Modified Sine Wave Solar UPSs are more expensive than the Pure Sine Wave UPSs. These types of UPSs are best suited for laptops and chargers which have in-built power adapters.
Sine Wave Solar UPS or Square Wave Solar UPS:
The power supply of alternating current that we use daily is actually a true or pure sine wave. UPSs basically generate square wave alternating current as they use solid-state devices.
It must have more sophisticated circuitry in a residential solid-state power UPS to generate pure sine wave or nearly pure sine wave alternating current. Well, it is much more expensive. Pure Sinewave UPSs are normally no less than 25 % costlier than their comparable square wave UPS as a thumb guideline.
Sine wave or square wave does not make any distinction for the lighting or normal heating devices like bulbs, geysers, and heaters. Be that as it may, for advanced electronic appliances, similar to PC, cooler, TV and so forth square wave AC which has rugged edges can be truly harmful.
Thus, if you want to take care of your sophisticated electronic appliances, you should definitely go for Pure Sine Wave UPS.
Size of UPS:
The decision of the size of UPS size relies on upon the wattage of all the electrical gadgets that should be associated with the UPS and in addition the most extreme number of gadgets that should be associated with the UPS anytime. All of the devices combined wattage should be upheld by the UPS.
Rating of UPS:
There are two general types of Solar UPS wattage rating
- Top continuous load rating
- Peak load rating.
Top wattage is the top continuous load rating that is accessible for long time duration.
Maximum wattage is the peak load rating which is given for the needed time for starting an electronic apparatus. By and large, a Solar UPS offering Peak load rating is favored as these solar UPSs are known to have a long life and are likewise more predictable in execution.
The power rating of a Solar UPS in VA
As opposed to Watts, Solar UPSs are basically rated in VA i.e. Volt-Ampere. Most of the appliances are rated in Watts.
The basic formula is:
Watt = Volt-Ampere x Power factor (W = VA x p).
Some appliances like TV have lower power factor while some others like incandescent bulbs have even higher power factor.
If we leave all these critical formulae of the electronic appliances, it can be safely assumed that the average power factor of our total residential load is of 0.6 only. For example, buying an 800VA UPS, we can run up to 480W appliances easily.
Well, there is a huge distinction between starting wattage and running wattage. As an example, if you switch on a 75W fan, it will start consuming around 150W – 200W of power. But the requirement of wattage slowly settles down when the speed of the fan picks up.
Solar Battery:
Solar Battery plays an essential role in deciding an Solar UPS’s performance. So, industrybuying advices you to check the specifications of the battery while buying right Solar UPS. Basically the battery’s size is decided by the projected run time and the wattage load. If you use a weak battery, it can lead to some discharging issues which can cause permanent damage of a battery.
How to calculate the battery size?
Size of the battery = Power rating of UPS in Watts ÷ Input voltage x Usage time in hours
There are some other handy formulae also such as: calculating the approx. start up load, converting Amps to Watts, and converting AC Watts to DC Amps.
