How Many Amps Does A 50 Watt Led Light Draw

Rain or shine we become a huge number of calls virtually solar power each day. We'll attempt to answer the questions asked most often so we can save you a phone telephone call.

Earlier nosotros become started, you should know that solar ability is not the cure-all for replacing spent energy. For example, some people are trying to recharge batteries for a trolling motor, boat, RV, house, electric scooter, backwoods cabin, etc., and they want information technology done in very short time, commonly in but a few days. Assume you have a discharged 100-amp hour battery and charge it with a thirty-watt solar panel under platonic summertime light conditions. After a total calendar week, the battery will exist just about fully charged. Using this example, you can see that information technology will take at least 100 watts of solar power to recharge a 100-amp hour battery in a few days.

Also, keep in mind that it takes direct sunshine on the surface of the panel to produce the maximum-rated power of a solar console. Conditions such as an overcast sky, shadows, improper mounting bending, equatorial direction or short winter days volition reduce the actual solar panel output to below the rated values.

VOLTAGE RATING

Nigh solar chargers are designed for 12 VDC, but we do have express availability on a 24-volt panel. Typically, when 24 volts or greater is needed, solar panels may exist wired in series, or nosotros can special lodge solar panels that are made to deliver more DC Volts such every bit 24V, 36V, 48V etc.

CONTROLLERS

Anytime you use a panel that is over 5 watts rated output, we recommend using a solar charge controller. Actually, a charge controller is a proficient idea in a majority of applications, as information technology tin provide several benefits such as preventing overcharge, improving charge quality, and preventing battery discharge in low or no-light weather condition. Some solar panels are fabricated with blocking diodes pre-installed that prevent bombardment discharge during low or no-light conditions. In most cases where a 6-watt or larger solar panel is installed, the utilize of a charger controller is highly recommended. In a nutshell, a solar charge controller acts like an on and off switch, allowing power to pass when the battery needs information technology and cutting information technology off when the bombardment is fully charged. Something to be aware of when selecting a controller is that they are typically rated in amps, while photovoltaic panels are typically rated in watts. That means a solar charge controller such every bit the Morning Star SS6L, vi-amp controller will work with nearly every panel we sell, correct up to about 70 watts.

Ability RATING WATTS AND AMPS

Solar panel manufacturers charge per unit solar output in watts. Every bit a rule of pollex, a rating of fifteen watts delivers about 3,600 coulombs (1 AH) per hr of direct sunlight. Every bit an example, the Pulse Tech SP-5 panel tin can output .33AH per 60 minutes of direct sunlight. This is a very popular panel for maintaining unmarried and dual batteries for stand-by and storage applications.

HOW DO I FIGURE SOLAR Console SIZE

The first affair to call back about solar power is that it is all a matter of numbers. The power y'all require vs. the power the panel can put out. Earlier y'all tin even become started when purchasing a panel, y'all need to know how many amp hours or watts you'll need to produce in a gear up menstruation of time. This figure could be measured in hours or days. Since there are 24 hours in a day, we suggest you use that as a baseline. Kickoff, determine your total electrical consumption in that fourth dimension catamenia. So effigy the amount of direct sunlight the solar panel will receive in that time catamenia and come up with a total corporeality of watt hours needed. Yous should ever err on the side of caution and over-gauge your ability needs. Typically we run into an average of 4 hours of usable sunlight in the wintertime, and six hours of usable sunlight in summer. Granted, there are exceptions to these averages, only erring on the side of caution creates a more reliable solar arrangement. These averages as well help compensate for variables like shade, clouds, console angle, etc. Once you accept a good handle on your power requirements, I suggest yous go to our Solar Reckoner.

OUTPUT Weather condition

Solar panel ratings are calculated in bright straight sunlight. Conditions such as indirect sunlight, overcast and fractional shade weather condition will subtract the output. We always recommend over-sizing the size of your solar array, every bit these weather condition occur ofttimes. As well, remember that the length of daylight in summertime vs. winter tin can make an touch on.

One of the biggest errors commonly seen is when a solar array is designed in summer using summer daylight hours, but then it'due south also used in the wintertime. The first complaint is often related to the batteries no longer belongings up under load. This is a gradual procedure that begins when you lose daylight hours, and you start taking the battery pack beyond a l% depth of belch. When this happens, the batteries start to sulfate at a much quicker charge per unit, and begin to no longer concur nether load. Equally you lot can imagine, this is an expensive mistake! The solution by and large involves more panels and new batteries with a higher Amp/Hr reserve. Therefore, nosotros propose our customers to be bourgeois when accounting for daylight hours. Also, if yous program to utilize a solar array year-round, then yous need to cistron in your daily solar input for winter.

OPERATING A DEVICE Directly FROM A SOLAR PANEL BATTERY CHARGER

Nosotros carry several foldable/portable solar panels for backpacking that come with a female cigarette lighter adapter. This adapter allows you to power 12v accessories that commonly employ a 12v DC plug. In social club to connect directly to a panel, the device cannot be sensitive to voltage variation—otherwise they may shut downwardly. To solve this problem, it'due south best to use a small battery equally a storage vessel for energy that volition provide constant source of stable, reliable power. To practice this, we recommend using a solar charge controller, Y-connector with a battery inline on one leg, and the female cigarette socket on the other leg.

ARE SOLAR PANELS Weather PROOF

Nearly all solar panels are designed for outdoor installation, every bit this is where they will receive the best, near straight exposure to sunlight. Remember that anything less than that will cause the panel to produce less than its full-rated power.

Practise I Accept TO MAINTAIN SOLAR PANELS

A periodic inspection to remove dirt, debris and check electrical connections is all that is needed. Keeping the panel articulate of snow and droppings volition allow for better results.

HOW LONG DO SOLAR PANELS Final

Operation from a solar panel will vary, but in most cases guaranteed ability output life expectancy is between 3 and 25 years. This guaranteed life expectancy rating is usually 80% of the published rating of the solar panel. Of course, this volition vary from manufacturer to manufacturer, and as always, you typically become what yous pay for. Watch out for those cheap panels made in Paki-china-nam-istan.

Utilise OF A Ability INVERTER

Many folks use a DC to Air conditioning power inverter to convert 12 VDC to 110 VAC. Since they alter power from i form to another, inverters are power-gobbling monsters and should exist avoided when possible. If you take a choice of a 12-volt, DC-powered device or 110-volt Air conditioning device, go with the 12-volt DC device. There are DC devices on the market that either step down or step up DC power, and these besides use significantly more power.

FORMULA DC to AC via an Inverter

Formulas and Examples for 12- & 24-Volt DC Systems

This "rule of pollex" is intended every bit a general guide for estimating the DC amps required operating a DC to Air-conditioning ability inverter. Since the calculations yield guess values, an advisable safety gene should be considered when designing and specifying system components, such as wire, size and length. This basically ways "oversize your organisation."

12-Volt DC Systems

Formula: 12-volt inverters require approximately 10 10 amps DC input for each 100 watts output power used to operate an AC load.

Example: How many DC amps volition a 12-volt inverter require to operate 3 500-watt quartz lights, or a 1500-watt electrical heater?

Answer:

• 1) Total watts = 1500
• 2) 1500 watts/100 (from formula) = 15
• 3) 15 X x amps (from formula) = 150 amps.

This is the DC current the inverter will use to operate the 1500-watt load. Note: If these 150 amps are drawn from the battery for one hour, 150 amp hours of battery power will be used.

To support 150 amp hours of battery power, 300 amps of battery capacity should be used for maximum battery life and performance.

24-Volt DC Systems

Formula: 24-volt inverters require approximately 5 amps DC input for each 100 watts output power used to operate an Air conditioning load.

Case: How many DC amps will a 24-volt inverter require to operate iii 500-watt quartz lights, or a 1500-watt electric heater?

Answer:

• 1) Total watts = 1500
• 2) 1500 watts/100 (from formula) = 15
• 3) fifteen X 5 amps (from formula) = 75 amps.

This is the DC current the inverter will employ to operate the 1500-watt load. Note: If these 75 amps are drawn from the battery for one hr, 75 amp hours of battery power volition be used.

To support 75 amp hours of battery power, 150 amps of battery chapters should be used for maximum battery life and performance.
