I cannot recommend the ATS (automatic transfer system) more, such a brillient device.</p> <p>By installing the ATS i am keeping my solar power generated off grid, but with on grid backup for any loads i attach to it. Also keeps me away from any danger introduced by back filling the grid</p> <p>So i can run a 24/7 load which will automatically flick over to main power when the batteries are low. At the moment i am powering my attached server (the load) approx 33% of the day. I could power my server for longer if i had a larger battery attached to solar. Its currently winter, so sunlight hours are also limited.</p> https://sigtar.com/2019/07/20/lead-acid-battery-state-of-charge-chart/ Sat, 20 Jul 2019 00:00:00 +1200 https://sigtar.com/2019/07/20/lead-acid-battery-state-of-charge-chart/ <p>Lead acid batteries do not like being completely discharged. I have used the following chart for reference, in most cases i only discharge my battery to 50% DOD (depth of discharge).</p> <p>Even deep cycle lead acids life (max charge cycles) will be extended if it is not completely discharged. It is also generally recommend to completely charge your battery after use - i.e. take the battery back to full charge in a single cycle.</p>
