Inverter Battery Maintenance Tips

*Install your inverter in a well ventilated area. The inverter battery gets heated up during charging and operation. An airy place reduces the heating up of the battery. It also reduces the frequent water topping requirement.inverter battery installed in ventilated area
After installation use battery on a regular basis. When your deep cycle battery is being used to power a mechanism, the charge needs to be monitored so you do not find yourself without power unexpectedly. Deep cycle batteries tend to discharge about 45-75% of its capacity, depending on the manufacturer. So how do you check the charge of your battery? There are plenty of fine tools out there to help you out, such as voltage indicating digital monitors and amp-hour meters. Use one of these to check the current charge of your deep cycle battery. They should be recharged when they indicate a 50% charge, but never let them get lower than 20% to ensure a long life.

*Protect your inverter battery from sulfation. Lead-acid batteries, such as deep cycle batteries, run the risk of sulfation if left uncharged for too long. Sulfation occurs when the lead sulfates crystallize, and your battery can no longer accept a charge. Once this occurs, it is generally too late to save the battery, as the battery is destroyed by expanding sulfate deposits that crack the battery plates, rendering them incapable of conducting a current. To avoid the risk of sulfation, fully recharge your deep cycle battery following a discharge cycle. Make sure to have periodic charge cycles to keep your battery healthy. Prevention is the ultimate protection against sulfation.
Keep the battery terminals corrosion free and rust free. If the terminals get corroded pour hot water + baking soda solution on the corrosive area or use a tooth brush for cleaning. This will remove the corrosion. Once the terminals become corrosion free, apply petroleum jelly or Vaseline on to the terminals, nuts and bolts to avoid future corrosion. Rusting and corrosion are very bad for battery performance. Rusting in terminals reduces the current flow to and from from the battery. This restricted flow of current results in slow battery charging which ultimately reduces battery life.cleaning an inverter battery with a brush

*Always keep the surface and sides of battery clean and dust free. Use cotton cloth to clean these surfaces.
Be careful that the vents around battery are dust free and open. Blocked vents lead to hydrogen gas accumulation ,which may lead to bursting of battery.
From safety point of view, install the inverter at safe places in your home which is out of the reach of children or a less used area. But at the same time make sure that it is airy and properly ventilated.
Replace your battery if it is dead or damaged. Regular inspection will keep you updated on your inverter and battery conditions.

There are 3 types of technology utilized in the solar panels available on the market today, these are monocrystalline, polycrystalline, and thin film amorphous.

As the names suggest Monocrystalline and Polycrystalline are both types of solar cells that are made from crystalline silicon. Almost all quotes you will get when considering buying solar panels for your home will use crystalline solar panels.

2-3 years ago the most common type of solar panel used in residential solar installations were monocrystalline solar panels but in the last three years polycrystalline solar panels have become the most commonly used solar panels in residential solar installations in America.

These types of crystalline silicon solar panels are known in the industry as simply 'Mono' or 'Poly' panels.

In my humble opinion the choice between monocrystalline and polycrystalline solar panels is not something that you should lose too much sleep over when looking to purchase solar panels for your home. It is more important that you choose a good brand of solar panels. A good brand of solar panels is from a company that invests heavily in the quality of their manufacturing process and invests heavily in their reputation. Click here to see reviews of different solar panels to find the best solar panels.

Both monocrystalline and polycrystalline solar cells are very similar in performance. What really determines your outcome in terms of system performance over the lifetime of the solar panel is a lack of defects in the manufacturing process and having a company that will replace the panels if their performance falls below the warranted levels.

Thin film is a totally different technology. It is much less efficient and therefore uses much more roof space. Its one advantage is that it performs better in low light conditions, when there is partial shading of the system or in extreme heat.



The key facts about each type of solar cell:


Monocrystalline
Monocrystalline
Overview and Appearance
This is the oldest and most developed of the three technologies. Monocrystalline panels as the name suggests are created from a single continuous crystal structure. A Monocrystalline panel can be identified from the solar cells which all appear as a single flat color.

Construction
They are made through the Czochralski method where a silicon crystal ‘seed’ is placed in a vat of molten silicon. The seed is then slowly drawn up with the molten silicon forming a solid crystal structure around the seed known as an ingot. The ingot of solid crystal silicon that is formed is then finely sliced ingot what is known as a silicon wafer. This is then made into a cell.

The Czochralski process results in large cylindrical ingots. Four sides are cut out of the ingots to make silicon wafers. A significant amount of the original silicon ends up as waste.



Polycrystalline
Polycrystalline
Overview and Appearance
Polycrystalline or Multicrystalline are a newer technology and vary in the manufacturing process.

Construction
Polycrystalline also start as a silicon crystal ‘seed’ placed in a vat of molten silicon. However, rather than draw the silicon crystal seed up as with Monocrystalline the vat of silicon is simply allowed to cool. This is what forms the distinctive edges and grains in the solar cell.

Polycrystalline cells were previously thought to be inferior to Monocrystalline because they were slightly less efficient, however, because of the cheaper method by which they can be produced coupled with only slightly lower efficiencies they have become the dominant technology on the residential solar panels market.

In November 2015 Trina Solar announced that it had produced a multi-crystalline cell with efficiency of 21.25%. This should allow them to produce polycrystalline modules with efficiencies between 18-20% a concept that was thought impossible as recently as 2013.

Underpinning the new record for p-type multicrystalline solar cells has been the continued quality improvements of multicrystalline wafers that have helped pushed standard 60-cell multicrystalline panels from 240W to 260W in recent years.

Polycrystalline are now very close to Monocrystalline cells in terms of efficiency.

Thin Film
Thin Film
Overview and Appearance
Thin film panels are a totally different technology to Mono and Polycrystalline panels. They are a new technology compared to Mono and Polycrystalline cells and would not be considered a mature technology as vast improvements in this technology are expected in the next 10 years.

A thin film panel can be identified as having a solid black appearance. They may or may not have a frame, if the panel has no frame it is a thin film panel.

Construction
Thin film panels are made by depositing a photovoltaic substance onto a solid surface like glass. The photovoltaic substance that is used varies and multiple combinations of substances have successfully and commercially been used. Examples of the most common photovoltaic substances used are:

Amorphous Silicon
Cadmium Telluride (CdTe)
Copper indium gallium selenide (CGIS)
Dye-sensitized solar cell (DSC)
Each of the above are known as different panel 'types' but all fall under the umbrella of being a Thin Film panel.

Performance
Thin film cells have got a reputation as being the ‘worst’ of the solar panel technologies because they have the lowest efficiency. However, this is only because they have a lower power efficiency which only means they require the most space for the same amount of power. Since they are becoming the cheapest panels to produce because of the low material costs for thin film they are quickly becoming the more economically efficient panel types.

Depending on the technology, thin-film module prototypes have reached efficiencies between 7–13% and production modules operate at about 9%. Future module efficiencies are expected to climb close to the about 10–16%.

The market for thin-film PV grew at a 60% annual rate from 2002 to 2007. In 2011, close to 5% of U.S. photovoltaic module shipments to the residential sector were based on thin-film.




Advantages of Monocrystalline
Monocrystalline solar panels have the highest efficiency rates since they are made out of the highest-grade silicon. On October 2 2105, SolarCity announced that it has developed the world’s most efficient solar panels. The new panels convert more than 22% of sunlight into electricity.
Just days later Panasonic announced it had trumped that achievement. A Panasonic solar panel has established a new world record module conversion efficiency of 22.5% on a commercial sized prototype using solar cells based on mass production technology. The test results were confirmed by the renowned Japanese National Institute of Advanced Industrial Science and Technology. The 72-cell, 270-watt prototype incorporates newly developed enhanced technology that will eventually be scaled into volume production.
Panasonic also says it is introducing the HIT® N330, the latest addition to the company's high-efficiency hetero-junction photovoltaic module product line and its most powerful photovoltaic module to date. It will be available in the UK and other European markets starting in March, 2016. Manufactured at Panasonic's state-of-the-art, vertically integrated solar fabrication facilities in Malaysia, HIT® N330 features 19.7% module-level efficiency and a nominal power output of 330 watts.
Monocrystalline silicon solar panels are space-efficient. Since these solar panels yield the highest power outputs, they also require the least amount of space compared to any other types. However, monocrystalline solar panels produce marginally more power per square foot of space used in an array and so.
Monocrystalline Panels have a long lifespan. Most solar panel manufacturers put a 25-year warranty on their monocrystalline solar panels. Because both types of crystalline solar panels are made from crystalline silicon, a very inert and stable material it is very likely that these solar panels will last much longer then their 25 year warranty life.
Monocrystalline solar panels tend to be more efficient in warm weather. With all solar cells electricity production falls as temperature goes up. However, this degradation of output is less severe in monocrystalline panels than polycrystalline solar panels. However, in practice the difference is very small. The level to which each solar panels production falls as temperature increase sis called the temperature co-efficient and is published with the specifications for each panel.
This article is solely about different types of solar panels. If you want to learn about what other equipment a photovoltaic system consists off, go to Solar Power System.


Disadvantages of Monocrystalline solar panels
Monocrystalline solar panels are the most expensive. In recent years a rash in installation of polycrystalline ingot, cell and module production efficiencies have mean that polycrystalline solar panel have become more common and have benefited from costs advantages over mono panels. Most manufacturers that still make mono panels have targeted the premium end of the market.



Advantages of Polycrystalline solar panels
The process used to make polycrystalline silicon is simpler and cost less. The amount of waste silicon is less compared to monocrystalline.
Polycrystalline solar panels tend to have slightly lower heat tolerance than monocrystalline solar panels. Polycrystalline solar panels will tend to have a higher temperature co-efficient than solar modules made with mono cells. This means that as heat increased output for this type of cell will fall less. However, in practice these differences are very minor.



Disadvantages of Polycrystalline solar panels
The efficiency of polycrystalline-based solar panels is typically 14-16%. Because of lower silicon purity, polycrystalline solar panels are not quite as efficient as monocrystalline solar panels.
Lower space-efficiency. You generally need to cover a larger surface to output the same electrical power as you would with a solar panel made of monocrystalline silicon. However, this does not mean every monocrystalline solar panel perform better than those based on polycrystalline silicon.
Monocrystalline and thin-film solar panels tend to be more aesthetically pleasing since they have a more uniform look compared to the speckled blue color of polycrystalline silicon.



Advantages of Thin Film solar panels
Mass-production is simple. This makes them and potentially cheaper to manufacture than crystalline-based solar cells.
Their homogeneous appearance makes them look more appealing.
Can be made flexible, which opens up many new potential applications.
High temperatures and shading have less impact on solar panel performance.
In situations where space is not an issue, thin-film solar panels can make sense.

Disadvantages of Thin Film solar panels
Thin-film solar panels are in general not very useful for in most residential situations. They are cheap, but they also require a lot of space. SunPower's monocrystalline solar panels produce up to four times the amount of electricity as thin-film solar panels for the same amount of space.
Low space-efficiency also means that the costs of PV-equipment (e.g. support structures and cables) will increase.
Thin-film solar panels tend to degrade faster than mono-crystalline and polycrystalline solar panels, which is why they typically come with a shorter warranty.

There are so many things you need to consider before hiring an installer for your solar and inverter equipments, first you need to try to detect how knowledgeable he is by reading up basic ideas about equipments, installation and cost. The solar components market like the TVs and phone market, is characterized with people offering different components at varying prices but unlike other electronics, Solar industry in Nigeria is face with lack of information about brands on Inverters, Solar Panels, Solar Energy Companies and so forth. do not want to hear about shade and grades of components, their individual specifications-what make Inverter brand A different from Inverter brand B, or why two solar panels of different watts have different module configurations.People are often put off when they hear high prices of components.Well,Inverters have not evolved to the point in Nigeria where it becomes a necessity that people must queue for specific brands just like people patiently wait to get specific brands high end mobile devices like iPhones and Samsung brands. The reason you have different inverter prices can be due to one of these four listed important reasons.

Specifications: Solar panels, inverters, solar chargers and all come with detail specifications by good manufacturers and are designed for specific duty. It is more like TVs, all 42 inches TVs are not the same, some come with different specifications to suit different needs, some Televisions are even energy saving, low wattage; Some mobile phones come with high pixels, cameras, resolution and battery capacity.Same way, you shouldn’t expect an inverter of N30,000 to function as a N100,000 of another brand. It advisable that when choosing an Inverter to always get a first-hand information on the inverter specification, dig down to know the real output power, if it a pure sine wave or pulse modulated wave output. Know if it is hybrid or not, or if it has a battery monitoring device or not. Some inverters are transformer-less, some are lower powered while others are high powered.So, the question will be, what do you want to use the inverter for?Don’t get carried away with your technicians’ choice or your low budget decision. Having power come with a cost, and the reliability is dependent on cost as well.

Functions: We have analyzed specifications on inverter, same arguments go for Solar Panels, Controllers and batteries. There is a reason why one has detailed and trusted specification than others, don’t just fall for the cheap things. If you would not buy a phone of N2,500 advertised on the street of Oshodi, then you should be more careful about your inverter choice.I have digressed a bit, functions are important in the choice of a good inverter. Do you want an inverter with inbuilt controller or not, what is the amp capacity of the controller you want? It is advisable that you go for an inverter that best fits to your design.Some inverters have stabilizers, some come with selectable voltage range.Inverters as well can degrade the lifespan of your batteries, so be careful in your choice. It is vital you carefully choose based on period, designs, cost, location, space and other conditions.



Brand: I assume you should know the difference between an iPhone 7 and Tecno Canon 8. Both are good phones but one comes with composition and brand superiority; and that is how Inverter brands are as the companies have invested money into research, marketing and branding to build what would last. A Schneider Inverter of 1kW product cannot be compared with a 1kW Sukam because both are not of the same brand and inbuilt spec. Hence the prices would always differ.



Warranty: As explained there are several manufacturers but one holds a better name and has long lasting proof in terms of durability and longevity. It is just the same way we buy TVs and Laptops, some holds longer warranty period which shows to speak about reliability and trust than one with few months or years of warranty.



A product with a longer warranty period would be quite more expensive than one without. Longer warranty is good proof of a brand to trust as they have done all to ensure devices are protected. This shows real value for money.



Well, these are some of the important things to consider before choosing a solar component, especially your inverters as there are several substandard products in the Nigerian market. You can always let us help you make the right decision by helping you out with the best choice for your solar or inverter installation.
