Charging of lead acid batteries is not an oft-spoken or documented topic. So here I would like to describe how to charge lead acids properly using the 3-stage method (Bulk, Absorption and Float) or the CC-CV method as shown below. Particularly, the “Charging current during Bulk phase” and the “Time for Absorption phase” that [...]
Let’s get the basics right for C rate.If someone says to you that they are supplying a 100Ah battery, then it has no meaning. It is incomplete information. It is like a shopkeeper saying to you, “I will give you 2 Oil”. Whether it is 2 liters of Oil or 2 bottles of Oil has [...]
Solar Battery: Design it right. In solar applications, a lengthy charge time is not desirable since we only have a maximum of 4-6 hours of peak sun each day due to limited daylight and varying weather conditions. To ensure that the batteries receive enough charge, batteries must be adequately sized to prevent deficit charging [...]
The reason there’s not a simple relationship between battery voltage and state of charge is that your solar system is constantly doing different stuff – electricity is coming and going all the time. However, there is a simple relationship between the two if the battery is disconnected from all chargers & loads and has [...]
"Lead acid batteries should be discharged only by 50% to increase its life" - is an oft used phrase. This means that we should cycle them in the 100% to 50% window as shown below in the Typical state of charge window parameter. So it follows that the usable capacity of a lead acid [...]
Lithium Ion versus Lead Acid batteries In this blog, we will bust the myth that lead-acid batteries are cheaper than lithium ion batteries armed with data. Lithium ion is way cheaper than lead acid batteries and we're going to use battery studies and data sheets to substantiate the claim. We are going to talk [...]
Peukert’s Law and Lead Acid Batteries Note: This blog is for battery enthusiasts. To understand peukert's law and with an intermediate knowledge about batteries and terms like C-rate. Let's talk about the capacity of different solar batteries in real-world circumstances because battery manufacturers are advertising a capacity rating in Ah and a lot of [...]
In 2017, EcoSoch commissioned a 3.7kWp off-grid project using a Studer inverter with Waaree Solar Panels for our customer at Anekal in the outskirts of Bangalore. Due to rodent issue at this site, the rats were chewing off the cables and causing ground faults which led to a shutdown of the system. As part [...]
Giving the residents of Karnataka a chance to self consume the Solar power they installed. KERC came up with few changes in their existing Solar Power policy for rooftop. The Hon’ble KERC vide order dtd: S/03/1 dtd: 19.09.2016 has issued Modification to the order 02.05.2016 in respect of determination of tariff and other norms for [...]
We at EcoSoch are always proud to own a REVA for our company. We are not only using it for our personal transport but also use it to deliver our Energy efficient Fans, LED Lights, Composting Pots to many of our customers. It had not only attracted many ogles like no other vehicle we ever [...]
