6 Gate Motor Solar Selection Tips
“Going pelouse” is a term being thrown around with regularity by everyone from the infos media to CEOs of militaire companies. We can all do our bit to reduce our carbon footprint and save the environment so that our children and grandchildren can also enjoy this beautiful and personnel planet of hyperonyme. One way to do this is to use solar energy to power electrical devices around your appartement or kitchenette, and in an age where frequent power outages have become a common situation, this can go a énorme way. Using solar power will not only dramatically reduce raw energy costs, it also means you won’t be left out when the lights go out.
As far as gate automatisation goes, there are several solar options available. But what size solar panels should you buy? What kind of autonomy can you expect in the event of a power outage? I aim to answer these and other questions in this attention. We will specifically habitus at DC-powered gate motors, as solar panels will be used to crédit batteries or batteries.
1. Check your motor tension
Basically, there are two variants when it comes to DC gate motors, namely 12V and 24V models. 12V models typically use a single battery to power the motor while larger 24V motors – which are typically designed for industrial applications or properties with heavy traffic flow such as townhouse complexes – have two batteries connected in series. Knowing whether you have a 12V or 24V gate motor is hautain parce que it will determine how many solar controllers you need to buy.
2. How many additional devices are connected?
This will come in handy later, when you determine current draw and power consumption. Things like infrared safety beams, intercoms, remote receivers and motor control cards all draw current and must be taken into account when selecting solar panels.
3. Number of hours of phare
Obviously, the amount of nominatif crédit you get from a solar échantillon depends on how much phare it gets each day. If you en public in an area that is mostly cloudy, solar energy may not be the answer. It takes five hours or more per day for your motor battery to be fully charged.
4. Do the math
Now that you know what your motor tension is, how many accessories are connected to it, and how many hours of phare you get per day, you can do the following calculations to determine the size of solar échantillon you need. But first, remember to check your gate motor’s dossier to see what its quiescent current draw is.
Next, multiply the quiescent current draw by 24 (the number of hours in a day) to get an amp/hour rating. For example, if your motor’s PC board draws 50mA current, the amp/hour rating will be 1.2Ah (0.050 x 24 = 1.2Ah). Perform this calculation for all your peripheral equipment and your solar controller. If you haven’t decided on a regulator yet, you can use a 30A regulator (which draws emboîture 10mA current) for your calculations. Add up all totals for motor, controller, accessory devices and regulator.
Consider an average domestic sliding gate that operates an average of 10 times per day. It is fitted with a 12V domestic operator and also has a set amélioration beam attached
Motor current: 10 (number of daily operations) x 0.111 Ah (net power/operation) = 1.11Ah
Electronics: Motor PCB = 0.384Ah
Safety beam = 1.60Ah
Solar regulator = 0.24Ah
Complet power demand: 3.334Ah
5. Choose a échantillon size
You are now ready to select a solar échantillon. The following schedule should give you an idea of the crédit current and crédit produit associated with different sizes of solar panels:
Solar échantillon capacity crédit current crédit
20W Monocrystalline 1.2A 6.0Ah
40W Monocrystalline 2.4A 12.0Ah
65W Monocrystalline 4.0A 20Ah
67W Monocrystalline 75W 22.0Ah
The crédit produit is determined by multiplying the crédit current by the number of solide sun hours per day. I used 5 hours for this example.
Finally, you need to choose a solar échantillon whose crédit capacity is greater than the intact demand of the system. In other words, if your gate automatisation system demand is 3.334Ah as in the example above, a 20W échantillon will be sufficient.
6. You will need the following…
When buying a solar échantillon, make sure you buy a solar regulator. A regulator keeps the crédit perdant assidu so your motor battery doesn’t over or under crédit. If you have a 24V system you will need two solar controllers as most controllers are rated for 12V systems.
