September 26, 20232 yr Author I have a 10KW Volta battery and a 8KW Deye inverter which allows me to set times when to connect to the grid, etc. I set each time period at 4 hours intervals to dovetail with load shedding, eg 02:00 - 06:00 battery (10KW) at 40%, 06:00 - 10:00 battery at 40%, 10:00 - 14:00 at 40%, 14:00 - 18:00 at 50% ( the sun is now getting weaker, time to build up reserves), 18:00 - 22:00 at 80% ( on a sunny day the battery can be at 100%, ie I start the "night shift" with a full battery of solar power), 22:00 - 02:00 at 70%, ie I am now powering down to make space available in the battery to when the sun starts re-charging the battery. I would like to know whether this setting strains the battery and/or the inverter? In other words what is the ideal setting for both the inverter and ensuring a long life for the battery?

Shouldn't be any undue stress to either component - the ideal settings are those that meet your needs

No strain on the equipment at all. However your average load, grid availability and weather dictates the efficiency of your system settings. 40% is a bit too close to the low battery alarm trigger(35%), it might not be enough to push you through longer power outages of bad weather. I would suggest the battery stays on 50/60%. Geyser can be connected through smart load and benefit from surplus solar power during the day
September 27, 20232 yr Author Thanks for your comments. When there is an upcoming loadshedding event, I power up to about 60 - 80% during the preceding period, depending on time of day and expected consumption. Good to know I am not straining the system. Klaus
