  1. So then, based on this, I should change the table below for the two instances of 100% fully charged to say 98% or even 95%?
  2. Hi Vani, I am particularly interested in an answer to your Point 2. MdF
  3. That's a good point. What I do think we can afford for now is to increase PV from 8 panels to 12 which should make a difference for providing extra power during the day for essentials and to charge the battery. MdF
  4. Yes, we draw from the grid after the PV stops for the day. So I agree with you saying we should draw more from battery to save money. The issue is that I only have 1 battery at 5.1kwh which I need to also keep partially charged in case there is loadshedding or a power outage. It would be nice to run the battery down to about 30% SoC but then what happens if loadshedding kicks in in the morning? (catch 22)? I obviously need to look at getting a second battery to improve storage but that comes at a cost at the moment. MdF
  5. Morning All, So, I have been playing around with the settings for a week now and have settled on battery discharges overnight that results in an SoC of about 50% before solar starts to kick in and recharge. Should I be discharging the batteries further or do you think the 50% discharge level is enough "exercise"? MdF
  6. As far as I understand it, Solarman Smart is the user app where you don't have access to the backend stuff like Wi-Fi setup etc. Solarman Pro is for the installers app where they have access to more setup functionality. MdF
  7. So, if loadshedding happens, how does the Power setting in the Time of Use table affect power output to your required load? In other words, if the power setting for any given row in Time of Use is set at say 2500 and loadshedding happens, the battery will only discharge a maximum of 2500 even if your load might be more? MdF
  8. Morning All, I have the same inverter. There must be a more practical way of updating inverter firmware than having to send an email with serial number to support? Can one not connect a USB card reader via the R232 cable connection to update firmware?
  9. Hi EnT, Your second attachment looks correct for what you are wanting to do. However, I can not comment on what will happen in terms of you wanting to Export to Grid and how that will affect your setup. But I am sure there are others here how will be able to assist. MdF
  10. Thanks Phil, yip agree with you there. I think my main objective would be to get the best "life span" out of my battery i.e. get it to work for the most number of years to produce the best SoC and power. There is a fine balance here between the two seeing that the battery was the most expensive component of my setup. Lots to ponder indeed. Edit: I think what I will have a look at is to start running the battery down a bit from earlier in the evening and not wait until midnight.
  11. Morning All, Next question on this thread journey: What is considered "good exercise"? Should one try and run the battery down to your base limits (in my case 35% SoC before the alarm goes off) or is something like going from 100% to 70% SoC overnight still seen as doing some good? MdF
  12. Afternoon All, Thank you to everyone who has posted on this topic, your assistance has been much appreciated. So, I had a successful first night of running the battery during the night and recharging it again with solar the next day. I'll be honest, things eventually clicked in to place for me in understanding this whole thread simply by watching what was happening on the system. So, I started at midnight last night with a SoC of 83%. The battery SoC got to 48% at 7:03am this morning and reached 100% SoC via solar by 10:03am. Just one last thing to understand and that relates to the Power column. My understanding is that if you set a SoC of 35% during the night with a power setting of say 2500, this means that the battery will only ever discharge to a maximum of 2500 wats at any one time should that be needed in the system? Does this also mean that you can make these power settings to ensure that you have enough power in the system to get through the whole night and prevent say someone switching on the kettle at 4am and running the battery flat (so to speak)? MdF
  13. Just a quick question regarding the battery alarm screen: Should I not set the first 2 rows SOC to 31% so as to always prevent a low battery alarm from sounding (Note: I have changed the Low Batt setting to 30% already)? MdF
  14. Yip TY, that was my thinking cos the alarm on the Deye is also a "screamer" Might bring that down from 35% to 30%. Will have to try the system out and see what happens
