    @fanievb

    Thank you for the assistance.

    Do not have all the info with me, will get tonight.

    This is wat I have:

    SOC settings and few other pics. The dashboard is taken on similar time frames and weather.

    The panels have the capacity to perform better, but it does not, If I Understand your post correct our priority is perhaps not on battery.

    Why are you charging from the grid??? by ticking the grid box, you are telling your system to charge batteries from both solar and the grid, which means it's 50/50 split. And you use the grid to charge your batteries at night. 

    Suggest you;

    1. untick the grid box (you can change that when you have overcast days and need to supplement in the event of loadshedding)
    2. check you load priority setting
    3. change your SOC requirements according to usage (see mine as an example) very experimental and you need to adjust to your needs.

    Remember when you have grid power and battery (no loadshedding) the system only uses battery up the selected SOC and then switches over to grid only (unless there is something coming in from the PV, which you are blocking by charging from the grid)

    the load priority setting is on the same screen, just select the "system 2" tab at the top

     

  2. @DJuice what's your settings for the following;

    1. timer use,
    2. SOC (on the timer)
    3. PV priority (load or battery)

     

    Mine is set to timer with different SOC per specific time

    If you set it to battery priority it'll charge the battery up to selected charge and then load when the SOC is reached (see below)

    If load priority is ticked, all PV goes to load and excess to charge the batteries

    Do you have the sunsynk logger installed? Much easier to set up from there

    Loving this thread and learning a lot from it. I just had a quote last week for a PV setup. We're in a different position to a lot of you folks in that we don't have load shedding to worry about, but electricity is very expensive and traditional energy generation doesn't help global warming, so we've decided to go the PV route. 

    We have an electric shower, so don't need hot water going into it, and our water pressure is so poor that a bath will take 45 minutes to run to about 8 inches deep, so only really need hot water for washing hands, dishes that don't fit in the dishwasher etc. At the moment, our house and hot water is heated by an oil boiler, with a 1200l heating oil tank outside. I have a TADO system to automatically manage the house, so run the boiler for an hour a day to heat up the hot water tank/geyser and that gives us enough hot water for our daily needs. That may change in winter, but the boiler will be running the central heating at that stage so hot water will be no issue. 

    The plan is to install a system now, without batteries but battery ready, and to set washing machine, dishwasher etc etc to run during daylight hours to maximise use of generated electricity. The excess then gets sold back to the grid for 25% of what we buy it for. Installation cost is about £6,800, which will hurt. 

    Next step, after we properly insulate the house (new windows, thicker insulation in the ceiling etc), is to install a battery system and a heat pump setup to control temperature in the house, which should be largely run by the PV system, especially in Summer. This will allow us to get rid of the oil boiler altogether and save the £1,200 per year (based on last years prices, twice that now) that we spend on heating oil. 

    We investigated a small windmill at the top of our property as the wind never seems to stop at our place, but decided, for all of the reasons listed on this thread, to stay away from that at the moment. 

    Anyway, the point wasn't to bore you all with my plans, but wondering if anyone has any thoughts on whether this is the right plan or is there a better way to do it? 

    check out the sunsynk channel on youtube

    They have specific solutions/setups which they describe for the UK. The whole buy during the day, store some for night use and sell the rest.

    I know this is load shedding related, but I'll add in service delivery related.
    Eskom is a 2nd tier supplier of electricity in Ekurhuleni, hence the tag service delivery related (or is that non-service

    I started (on Saturday) digging holes and laying foundations for rain water collection tanks, aka JoJo tanks. We have burst water pipes on a regular basis, resulting in low water pressure, as well as no water, on occasions.

    Then add the amount of rain we received in April, and I have a backyard that is being destroyed because of too much water. So I'm putting in 1000L slimline tanks (2 this year) and then 1-2 every year until all my gutters are collecting water. In the event of a municipal outage, I can still make a plan.

    in the eastern cape water cuts are the norm due to failing infrastructure (not even talking about the drought and water restrictions)

    I have 2 x 2500l tanks system connected to the house via a dab 132 pump and an additional 8500l in storage which I pump over to the main tanks when they run empty. Based on our average usage I have water for 23 days (without any rain).

    Hi...adding to the resurrection bid, I have a question. With the stage 6 load shedding schedules, my 100ah linknet gel batteries last about 90 mins, so can I connect the Linknet inverter to a generator to  charge the batteries during  that extra stage in the day ?  In this way the batteries  will last the stage at night, powering cctv and alarm. This is for a business btw. Or will the generator mess up the invertor ? Its a Ryobi 7.5 kva. TIA.

    generator needs to exceed or at least match your invertors' rating.
