The batteries necessary for solar applications should be able to sustain the requirements of a non-stable grid energy considering the irregularities in charging as well as in discharging. The solar batteries are used to keep the solar energy.
The lead-acid batteries have been used for decades to provide a reliable and renewable energy to off-grid household.This type of battery includes the gel and absorbed glass mat (AGM) models. The AGM batteries are mainly built for standby applications and a dual-purpose. There are many factors that affect the life of the battery. Lead-acid batteries that are flooded, need to be constantly refilled since the electrolytes evaporates when it is charging. The enclosure of the battery also needs a ventilation to prevent the accumulation of hydrogen gas to a dangerous level. Lead-acid batteries are toxic.
The vanadium redox flow battery (VRFB) is another option for the storage. However, it is very complex and requires equipment such as control units, sensors and pumps. It also needs a considerable space for installation. One advantage of the VRFB is the battery size can be increased just by adding electrolytes. According to the developers, it also does not have a cycling limitation. The lifespan of the batteries is not affected by discharging and charging of the batteries. This type of battery is not toxic and you can use it multiple times.
The most popular storage technology is the lithium-ion batteries. It delivers more cycles in its lifespan compared to the lead-acid. The most significant benefit is the high discharge and charge efficiency of the battery, which helps in producing more energy. When it is not in use, it loses a less capacity which is very beneficial when the energy from the solar installations is seldom used. The lithium ion is also light and independent making it easy to install as well as to change out.
The lithium-ion batteries are ideal for residential storage. It is cheaper compared to other type of batteries. The lithium-ion batteries are used in power tools, electric cars, tablets and even in cellphones. The lithium-ion’s energy density is higher which means it can transport and store more energy. It has a lower self-discharge which makes it more suited for modern applications. It does not require maintenance or refills since it is solid. It can be mounted on the wall and can be placed outdoors or indoors.
It can also use inorganic or organic cells. The batteries that are organic-based do not have toxins. It is environmentally friendly. On the other hand, the cells that are inorganic-based are difficult to dispose since it is toxic, hence, proper disposal is required.
If you want to install the battery on your own, it is better to get the lithium-ion battery since you can easily install it. It does not require any complex equipment like pumps in order to work. Also, it is low-maintenance so you don’t need to do a regular check on the battery. If in case the battery needs to be changed, you don’t have to worry since it has a light weight and it is self-contained which makes it effortless to replace.
There are two types of solar power inverter available in the market- the pure sine wave and modified sine wave inverters. The pure sine wave inverters produce the most constant and reliable wave signal while the modified sine wave inverters can be used in devices that are not sensitive since it creates a distortion of the sound or electrical hum.
The pure sine wave inverter is the best solar power inverter especially if you need to convert DC to AC daily like using a solar energy to supply your everyday need. It uses electronic circuits and toroidal transformers to convert DC to a smooth varying AC. Although it is more expensive compared to the modified sine inverter, the pure sine wave inverter last longer and its motors run in cooler temperature which makes it safer and desirable to use even regularly. There is also some equipment which requires a pure sine wave inverter to work or to produce its full output, these includes medical equipment, laser printers, the latest LED TVs, and even digital clocks. Some appliances that have a variable speed like the bread makers and speed drills needs pure sine wave to work correctly. All AC equipment and appliances that are available now in the market were created to work with the pure sine wave. It is similar to the power produced by utility companies, which is clean and have a lesser harmonic distortion.
The pure sine wave inverter is also very efficient since it filters the electrical noise made by the equipment. It produces a low electrical noise, so it does not produce any lines on your television and also you will not hear any electrical hum or buzz on your audio device. The equipment you use for telecommunication will also have a lesser noise and hum. It also minimizes the electrical and audible noise from audio amplifiers, answering machine, fans, fluorescent lights, television and fax.
The pure sine wave inverters make inductive loads work quieter, faster and cooler like in motors and microwaves. It also prevents your computer from crashing and problems your monitors. The pure sine wave inverter is ideal for sensitive electronic equipment particularly those that requires stability and a high quality. It eliminates any interference and overheating. It can also be electronically protected to avoid overload, over temperature, over voltage and under voltage. Not only that, the pure sine wave inverter is also compatible to every AC electrical appliance.
The only disadvantage of the pure sine wave inverter is it is more expensive and physically larger compared to the modified sine wave inverter. The benefits that you can get from the pure sine wave inverter is worth the price. And with modern technology, new equipment and devices are available from time to time, and also different inverter manufacturers are competing in the market, so the price of the pure sine wave inverter might become more affordable. And all AC equipment that is available at present in the market are call compatible and works best with the pure sine wave inverter. Most of the appliances that you have at home will work with this inverter. This is the type of inverter that you can definitely use every day.
