Issues Voltage fluctuations are variations in the voltage levels [...]

Pre-Charge Resistors: Essential for Dependable and Safe Battery Operation

By |2023-07-08T11:07:09+05:30July 8th, 2023|

Precautions to take before connecting Inverter to Battery When you are connecting any Inverter to the Battery (thru the fuse), you would have noticed sparking as shown below. You can also check out the same in the below video. https://youtu.be/_PgthByAYz4?t=630 This sparking happens because the capacitors in the Inverter try to get charged [...]

Charging lead acids properly

By |2020-06-09T20:33:30+05:30June 9th, 2020|

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 [...]

Criteria for sizing battery banks

By |2020-06-02T22:27:01+05:30April 22nd, 2020|

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 [...]

Understanding Battery Voltage and SoC

By |2020-06-02T22:32:57+05:30April 21st, 2020|

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 [...]

50% Depth of Discharge for Lead Acid Battery

By |2020-06-02T22:42:51+05:30April 21st, 2020|

"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 batteries are cheaper than Lead Acid.

By |2020-06-18T11:59:58+05:30April 15th, 2020|

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

By |2020-06-02T23:29:58+05:30April 1st, 2020|

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 [...]

Case Study – Resolving rodent issue | Agriculture + PV

By |2020-06-14T18:52:46+05:30February 10th, 2020|

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 [...]
