This datasheet from Victron shows the the number of Charge cycle always increases by using a lower %Depth of Discharge (DoD). You must define a spec to choose desired %DoD and thus capacity and thus lower cutoff voltage and thus lower cumulative Ah capacity* charge cycles. It occurs during charge transfers and life cycles reduce 50% for every 10'C rise above room temp and to some extent by the minimum % DOD or cutoff voltage you choose. This information is available on the battery itself:īattery aging is inevitable. I don't have the battery's datasheet handy. What is a safe level to set for the inverter's auto cutoff voltage so that I don't destroy the battery and also to prevent devices from cutting out while the battery still has a sufficient SOC? If the battery should not be discharged to less than 12V, does this refer to the battery's resting voltage or the lower voltage that I am seeing while it is powering devices? Sometimes the voltage drops to 11.5V or less and I lose power even though the battery's actual voltage is much higher. On this basis, I have set the inverter's auto cut off setting to 11.5V. Sometimes the measured battery voltage can jump as high as 0.5 to 1V when the inverter is powered off while it is powering devices. I have noticed that when the inverter is in a state of providing charge that the measured battery voltage is considerably lower than that measured if I switch the inverter off. I understand that deep cycle batteries should not be discharged below 12V (approximately 50% SOC). The inverter has an automatic cutoff feature at a nominated voltage. I am using an AGM deep cycle battery 130Ah 12V connected to 200W solar panels and a 500W inverter to power electrical devices such as fans, laptops and lamps.
