Solar Batteries - Lithium Ion Battery & its Types, Salt Water & Hydrogen Ion Battery

Solar Batteries Lithium-Ion Batteries: Lithium-ion batteries are another popular and widely used solar batteries nowadays. They are well known for their light and compact size, high current rating, high DOD value, and longer life span. The only drawback they have is that they are very expensive compared to other types of batteries. Lithium-ion batteries are made up of a cathode (Positive electrode) and anode (Negative electrodes), a separator between two electrodes, and an electrolyte that fills the battery's remaining space. The working principle of Lithium-Ion batteries Is based on the movement of lithium-ion between the electrodes through the electrolyte. Lithium-ion battery technology was previously used in laptops, cell phones, and other electronic devices only but over the years it has become more popular in solar energy applications. Pros and Cons: Pros: They have a high depth of discharge ranging from 80% to 90%. They are having high charge/dis...

Lead Acid Battery & Its Types

Lead Acid Battery & Its Type Lead Acid Battery: Lead-acid batteries are the same technology used to power the electrical system of most automobiles. It has been around for years and is commonly used as a home energy storage system for solar energy systems.  They are the oldest rechargeable batteries, and their main active material is Lead (Pb). They are reliable and low-cost batteries, deliver high currents and work well even at low temperatures. Although they are still available on the market at reasonable prices, their demand is fading due to the low Depth of Discharge (DoD) and shorter life span. Lead Acid Batteries are having few drawbacks which can be their heavy weight, Hazardous as lead (Pb) is a poisonous metal. Also, they lose capacity because of mechanical strain and aren't appropriate for too lengthy discharges because of the sulfation process. Lead acid batteries are of the following types, which are discussed below in detail, along with their working meth...

Wiring/Connection Methods for solar batteries in Solar Energy System

Image
  Wiring / Connection Methods for solar batteries in Solar Energy System   For both off-grid and grid-connected (with battery storage) solar systems, batteries are wired or connected to generate and get a specific voltage rating and ampere-hour capacity. Batteries are wired or connected in series or parallel or in both series-parallel combinations, to get the desired system voltage or current capacity.   Series Connection: In a series connection, the positive terminal of one battery is connected to the negative of the other battery and so on connecting all the negative to positive and positive to negative. As we know that in a series combination the current remains the same, but the voltages are added, thus the series connection of two similar rating batteries allows us to get twice the voltage rating as compared to a single battery. The capacity or current rating remains the same. For example:  if we are using two 12 volts,100Ah batteries and they ar...

Solar Battery Sizing for Solar Energy System

S olar Battery Sizing for Solar Energy System   If you planning to design a solar energy system and you are out of the grid or you want to generate an extra amount of electricity to store and also sold out it to extra to utility grids, you will have to deal with the batteries. When you start learning about solar batteries, you will encounter a bit of math. The overall goal when designing an off-grid battery bank is to have a system large enough to handle all your needs on a few cloudy days, but small enough to be charged via the panels. Similarly, for a grid-connected battery storage system, your solar panels' requirements and inverter sizing should be enough to cover your all-daily power demand and also, if possible, sold out the extra power to the grid.   Before discussing the steps of how to size your solar battery, let's a few basic parameters that we should know before sizing our system.     1-       Total Load (KW): Y...

Selection of Solar Battery System for Solar PV System

  Selection of Solar Battery System for Solar PV System Solar energy is a free, green, and the most important source of alternate energy. Solar batteries, being a very critical part of solar energy systems needs need proper attention and to be chosen carefully. During choosing better energy storage for your solar energy system, many technical parameters are found, but we will discuss a few very essential parameters that must be kept in mind.   1- Power & Capacity: Power is the rate at which energy is consumed. Its standard unit is the watt (W), but kilowatt (KW) is a more convenient unit used. In electrical terminology, power is the product of voltage and current. If a battery system delivers 12v and 100A, it means it is delivering 1200 watts or 1.2Kilowatts. Capacity is the total energy a battery can hold for use later. It is expressed in watt-hours (WH) or kilowatts hours (KWH) and is the product of total power used within the duration of time. A device havi...

Working of Solar Battery with Hybrid Inverter:

Image
  Working of Solar Batteries with Hybrid Inverter: A hybrid inverter is a smart inverter that combines the PV inverter with the battery inverter in a single unit, thus eliminating the use of two inverters in a single system. In the case of a Hybrid inverter, a single device converts your DC electricity into AC electricity and AC electricity into DC electricity. Hybrid Inverter eliminates the use of multi-inverters and thus making your system more economical.

HOW SOLAR BATTERY WORKS

Image
  How Solar Batteries works: Solar batteries are a great way to get the most out of your solar power system. They can be configured in a variety of ways, but the basics are simple. When the sunlight hit the solar panels it generates DC electricity with help of Photovoltaic cells, The DC power generated is converted into AC power with the help of a solar inverter, that can be used in our Houses to power our electrical appliances. If a solar energy system generated more power than its consumption, the excess energy can be either stored with the help of solar batteries or can be sent and sold to the utility grid (In the case of the on-grid system without a battery storage system) via a net metering mechanism. To better understand the working of solar batteries and how solar panels and battery storage systems are wired together, a method referred to as coupling will be discussed. Coupling methods are of two types:    DC coupled battery system AC c...
