Three of The Most Popular Batteries in South Africa Used for Solar

It is no secret that the type of battery used in solar applications have to perform an arduous job and need to meet the demands of heavy cycling, unstable power from the grid as well as irregular full recharging.

There are different types of batteries that are used for the various applications and need to meet a broad spectrum of unique requirements.

When looking at the different types of batteries for your solar power unit, there will always be a number of factors that need to be taken into consideration.

These usually include cost, cycle life as well as installation and maintenance.

Lead Acid Batteries:

Lead acid batteries are often incorporated in renewable energy and is reliably used in off-the-grid solar energy applications; a battery that has been used for solar energy, spanning decades.

Lead acid batteries are typically deep cycle and cost almost half the price of lithium-ion batteries.

Lithium-ion Batteries

Lithium-ion batteries are perhaps the most commonly used in storing technology, no matter the kind of application. These include three types – they are pouch batteries (tablets and smartphones), cylindrical batteries – used for power tools and prismatic,used in electric vehicles.

Flow Batteries

These include the Redox Flow Battery which are fast emerging as an alternative storage option.

The vanadium redox flow battery – also referred to as the VRFB is perhaps the fastest-emerging and technologically-advanced type of battery  used in solar applications.

With so many options and different types of batteries to choose from for your solar, ensure you select the right one for your needs.

Solar Thermal Solutions for Energy Savings

The cost of electricity is exponential – and keeping the environment at home or at work pleasant to work in, plus ensuring that water is heated at all times could impact hugely on your utility bills.

In many instances energy saving solutions could prove to be a costly exercise and is very often not affordable by the man-in-the-street.

Perhaps one of the smartest solutions and most effective energy options is the use of solar energy for and the installation of solar thermal solutions for all those energy needs and requirements.

Heating up buildings and water could prove to be a massive source of energy consumption and hugely expensive – by installing solar panels and solar thermal solutions for heating will assist in saving energy and reducing enormous electricity bills.

About your solar thermal solutions:

Using solar thermal heating solutions is a wonderful resolution to heating water and keeping the environment warm at an affordable cost.

This system captures the heat from the rays of the sun and uses it for heating water.

The solar panels that are placed on the roof absorb the heat and will heat up the solution panels; in return, the solutions will be pumped into the cylinder to heat the water.

By incorporating solar thermal solutions you will be able to fill most of your hot water requirements.

Furthermore, your energy bills will be reduced dramatically through the installation and use of solar and solar thermal solutions.

If You Wonder How Batteries Work

For those that have always wondered how solar and batteries work in conjunction with each other, there is a simple explanation.

How batteries work:

Solar panels charge batteries.

Solar batteries work by the conversion of the AC energy that is produced in the solar panels and is stored in the form of DC power in batteries to be used at a later stage.

In some instances, though, solar batteries have their own inverter and therefore are able to incorporate integrated energy conversions.

Larger solar systems will always require a battery that has a bigger capacity for storage of DC power.

When solar batteries are installed as part of a solar system, excess solar electricity for the home will be stored – this is instead of being sent right back to the grid of the power utility.

For those that have solar panels that produce a surplus of solar energy, the excess energy will be used to recharged the battery.

That means as and when the solar panels are no longer producing electricity, the surplus stored power will now be drawn from this surplus for cloudy days or night-time use.

Electricity is only sent back to the grid when the battery is fully charged and you will only draw power from the grid when the battery is flat.

Solar systems that have an excess solar storage will be able to store surplus solar power on-site for later use when the sun goes down and can also offer a short period of backup power when the power goes down.

The above is a brief synopsis on how batteries work.

State-of-the-art Engineer Systems Take Care Of Your DB Board Requirements

Only ever use professionals for the installation of intricate, tailored engineer systems when designing your DB board.

For individuals and businesses that need a unique system installed, it is advisable to choose the experts and to find a company prepared to incorporate and design basic design and distribution board layouts for your unique, individual requirements.

Tailored engineer systems will ensure your distribution board, which is also commonly referred to as a breaker panel, electric panel or panel board – are all components of an electricity supply system that distinguishes an electrical power feed into secondary circuits.

The general idea behind a distribution board is the protection of fuses or incorporating a circuit breaker for each circuit, all in a common enclosure.

Under normal circumstances a main switch is installed, and in recent boards, one or more residual current devices or residual current breakers will be incorporated with overcurrent protection, which will also be installed when using state-of-the-art engineer systems for all your DB board requirements.

Use Basic, Simple Guidelines to Ensure You Buy the Right Battery Charging Units

Don’t make your battery charging units an afterthought when investing in rechargeable batteries – batteries and chargers go hand-in-glove like peas and carrots.

It is no secret that good battery charging units make an excellent base for batteries that are long-lasting and perform at their peak.

Because users are usually unaware of how important a good power source is and that it could make a profound difference, it is important to investigate battery charging units at the start of a project and not at the , after all the hardware has been completed – this is especially important under adverse conditions.

When investing in battery charging units you need to:

  •         Invest in the right charger for the right battery, which will make a world of difference – and because       many chargers are able to service only one chemistry at a time, ensure that the voltage matches up with the charger.
  •         Charging a larger battery will take a lot longer than a smaller package, with the same applying in reverse.
  •         High wattage chargers will minimise the charging times and there are limitations as to how quickly batteries are charged – bear in mind that extra-quick charging will cause undue stress to the battery.
  •         Lead acid chargers should switch over to float charge when they are full.
  •         Nickel-based chargers need to switch over to trickle charge when batteries are fully charged.
  •         Li-ion will not be able to switch to trickle when full as they are unable to absorb any overcharging.
  •         Bear in mind that lead acid batteries should stay lukewarm, and nickel-based batteries will get warm to the touch only at the end of the charge.

    Always be aware of the temperature of batteries when they are charging..

Battery Tripping Units Will Safeguard Distribution Equipment Against Failure

Battery Tripping Units are principally used in industrial areas and applications. This is usually where DC applications in substations and switch rooms are needed for safeguarding power distribution equipment against failure.

Select Battery Tripping Units that are flexible and are customised to suit the unique demands and requirements to fit into a variety of industrial presentations.

The advantages of world-class Battery Tripping Units are numerous as they come complete with fully customised status, indicators, alarms and testing points.

Battery Tripping Units are dependable, robust and fortified and if preferred, remote monitoring could be an option.

Select professionals to install Battery Tripping Units – bear in mind that the key component of any switch tripping unit is state-of-the-art technology that is part and parcel of all applications.

This is how your Battery Trip Unit works:

If a fault is detected within the supply, a Battery Trip Unit is energised, and will trip the system to cut off the supply to the industrial equipment prior to any failure taking place.

It is essential for Battery Tripping Units to be installed properly right from the outset, plus they need to be maintained thoroughly and on a regular basis.

Successful operation of Battery Tripping Units is a direct result of regular and careful maintenance.

Numerous industries enjoy the benefits of Battery Tripping Units which will protect their equipment against faults, plus they will be guarded against equipment failure which could result in catastrophic costs to businesses and employees.

Recharge Your Batteries Using An Intelligent Battery Charger

Many individuals refer to battery chargers as being an intelligent battery charger or a smart battery charger. It makes little difference what terminology is used to describe a battery recharger – a device which is used to replenish the energy into a secondary cell by coercing electrical currents through it.

The charging process always depends on the type and size of the battery being charged – dynamics such as how much voltage is required and for how long the battery needs to be recharged for, and once the process is completed, what needs to be done have to be considered – all aspects that are taken into the equation when charging all types of batteries.

Certain batteries have a high tolerance against overcharging and can be recharged by connecting a continuous voltage source or a constant current source, depending on the type of battery; these chargers are simple and need to be disconnected at the end of each charge cycle.

Other batteries require cut-off timers so that the current is curtailed at certain fixed times – this is usually when the battery is fully charged.

There are certain batteries that can be damaged when overcharged – the end result would be reduced battery capacity and a reduction of the life of the battery – in some instances batteries could explode or over-heat!

In some instances, intelligent battery chargers could have voltage and temperature-sensing circuits as well as microprocessor controllers for safe adjustment of the charge current and voltage – these regulate the state of the charge and the cut-off time of charging the battery.

A Switch Mode Rectifier Will Suit A Wide Range of Applications

Providing Switch Mode Rectifiers and customising these to suit a wide range of applications is all-important.

Select the one best suited to your needs – with the latest innovative, technologically-advanced air and water-cooled switch mode DC-power models, you simply cannot go wrong.

Keep a look out for the most ground-breaking designs. It is important to use Switch Mode Rectifier suppliers that are professional and able to provide users right across the board with the best installation and operational advantages.

There are many advantages when making use of Switch Mode Power Rectifiers – these include:

  •         The design is compact – use wall, modular and rack structures – because the package is smaller, the               configuration will be neat and unobtrusive.
  •         Switch Mode Rectifiers will save businesses money – they are cheaper to run than conventional SCR             Units.
  •         High switching frequency enables less ripple.
  •         Many businesses will select and enjoy a precisely–controlled high current DC output with <2% AC Vrms             content.
  •         Higher efficiency provides for a faster control loop.
  •         You can now choose from a variety of models.

How your Switch Mode Rectifiers Works:

  •         The Switch Mode DC power supply is a solid state AC to DC power conversion configuration.
  •         This arrangement operates by correcting the AC input to an unfettered DC voltage.
  •         This transitional DC voltage is then cut using pulse-width modulation through an H-Bridge formation into         a high-frequency transformer.
  •         The output of the transformer is corrected and filtered to provide an exact controlled high current output.

PHD Powerhouse – The Myriad Uses of Lithium Ion Batteries

Lithium Batteries, or Lithium Ion Batteries, are used in a wide range of applications. In a high-tech world where technology has far-reaching uses from across the board, these batteries have made great inroads.

Lithium ion batteries are found in many devices such as laptops, cell phones, PDA’s and iPods. Because these batteries are some of the most robust rechargeable batteries, they are commonly used in countless devices.

These batteries stand apart from other more commonly-used batteries as they have a high charge density and high cost per unit, and all depending on the design as well as the chemical combinations and compounds in the batteries, the lithium cells can produce voltages ranging from 1.5 Volts to 3.7 Volts.

Take note that disposable lithium batteries differ from secondary lithium-ion and lithium polymer batteries which are all rechargeable – the ions in these batteries are transferred between the anode and the cathode which uses an interchangeable lithium compound instead of lithium metal as the connection material.

Lithium metal is known to be unstable, especially during the recharging stages; therefore research has shifted to a non-metallic lithium battery whereby lithium ions are commonly used and although lithium-ion batteries are a tad lower in energy density than lithium metal, lithium-ion batteries are a safer option provided certain caution is taken whilst charging or re-charging these batteries.

PHD Powerhouse – Lead Acid Batteries

Lead acid batteries were invented by French physicist Gaston Planté, and have been around since 1859. These are the oldest kind of rechargeable battery and even though they offer a very low ratio of energy-to weight ratio as well as a low energy-to-volume ratio, they are able to supply high currents which results in cells having a relatively large power-to weight ratio.

Lead acid batteries have changed very little over the years although there have been certain upgrades and improvements in the way they are manufactured over time.

Advancements continue to improve in energy density as well as the life of batteries and dependability.

All lead acid batteries have flat lead plates that are submerged in a pool of electrolytes and the regular addition of water is needed for most of these batteries. In today’s modern world lead-acid batteries are basically low-maintenance which are manufactured with excess electrolyte calculations to make up for any water loss during the life of the battery.

Perhaps the most important aspect of lead acid batteries lies in the recharging of these batteries – a converter/charger with single output voltage will certainly not charge the battery correctly.

Correct and proper charging as well as the correct maintenance of lead acid batteries requires intelligent charging system that will take care of battery issues and reduce the maintenance of your lead acid battery
