If someone can give me an explanation please, I suppose it will be the same for all batteries but for me it if for Pylontech lithium batteries. What is the meaning or definition of a charge cycle? It makes sense if the batteries run out at say two o clock in the morning and then gets fully charged via the grid, but for instance with overcast / rainy weather as is currently the case I will set the inverter to Grid at 17:30 in order to fully charge batteries that are 76 to 80% charged, when fully charged switching back to solar first, only using about . 70kwh to maybe 1.2kwh,creating a situation where batteries will last through the night until solar or PV takes over again, saving on full charge cycle, more or less 5.5kwh for full charge. After long explanation, will the charge from 80% also count as a charge cycle? Or even solar charging during the overcast day when swimming pool pump uses more power than what PV can produce until the sunlight allowed PV charging in between, reason for the question is how will it affect battery life in the long run, as the battery life is defined by changing cycles
