Posted March 18, 20232 yr Hi Guys If my timer settings were as below, could anyone give some clarity on the following please as I am trying to best understand the timer: 1. Am I correct in assuming that excluding 10h00 to 12h00, the system will charge the batteries from the grid should they drop below 20%, and that should the batteries drop under 50% between 10h00 and 12h00 the system will charge the batteries from the grid? 2. If I am correct with my assumption in 1, then to what level (SOC) will the batteries then be charged if they drop below the specified SOC (20% at all time and 50% between 10h00 and 12h00, as above). Basically assuming for example the battery drops to 20% at 1h00, the system will then charge from grid, but to what level of SOC, perhaps 100%? 3. Assuming for example again that system drops to 20% at say 3h10, the system will charge from grid, but then at 3h30 the system enters a "new" time period as specified (3h30 - 4h00), what will then happen? Basically one then assumes that the system starts charging from grid at 3h10 when it reaches 20%, then at 3h30 it may be at around 25% due to the charge from grid......will charging then stop as the new time period starts and system is over the specified minimum? Sorry for all the assumptions, but trying to understand this. If my thinking is correct (and I am not sure it is, thus asking) then if the system reached the lowpoint SOC during a specified period, then it charges from grid and does so either to 100%, or until the next time period as specified on the timer when a new set of parameters come into effect? Is this correct?

Is this correct? AFAIK when using the timer the SOC is kept at the % provided and not charged to 100%. This means if the 3h30 comes up with the same % grid charging will just keep it there and prevent discharge to lower than 20%

So then am I correct to say that the soc for any time period will be the minimum and system will either keep it there if soc decreases to the specified, and if it is under, then will charge to specified minimum, eiher from grid or not depending on selection?

But if you have panels connected, the battery will always charge to 100, regardless of the percentage configured in the timer

But if you have panels connected, the battery will always charge to 100, regardless of the percentage configured in the timer Thanks for adding the charging from PV. It would seem all inverters would charge from PV when available unless there is a setting to use UTIL only. I know my Axpert would also charge from PV even if the inverter is switched off.
March 19, 20232 yr Author Guys a followup question. I am very new to sunsynk and previously had a growatt system. My previous system I could change the charge priority to UTL from SBU to charge the batteries should the need arise. Is there an easy way to do this with sunsynk other than changing charge percentage and time in system setting?

If you untick use time in system Work Mode it will use the grid to power loads and charge the batteries
