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 [...]
If you go to their online store, you can see the Ah or Storage Capacity of a range of Exide Lead Acid Inverter batteries. With a terminal voltage of 12V, you get Ah ratings of 180.00, 165.00, 150.00, 130.00, 100.00, 88.00, 80.00 and 65.00. To know which battery to pick, you must know your load current [...]
