In winter we hardly ever get the battery up to 100% by 5pm, as a result the inverter toggles between grid and battery all the time. I thought if I set the system mode to 90% for the time slot 5 - 9pm, I avoid the inverter doing "overtime" switching between the two. It works quite well in that I finish the night with just enough power on the battery to tie me over until the sun does its thing. Clever move or stupid? Who would like to comment? Many thanks.

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

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?

I have a 8kw inverter connected to a 10kw battery. I am missing out on much production at peak times, hence I want to install an extra battery. Can I connect a 5kw battery to the current setup or do I have to install another 10kw battery?

When it is 08:00 in South Africa my Deye 8Kw will display 09:00, which is annoying when you want to set "Time in Use". Does anyone have a clue how to fix this? I suspect the firmware is set to GMT +3 which is for East Africa. Please help.
