  1. I can just make it through the night while keeping a bit of battery in reserve for load shedding on bad solar days, but yes, I need more panels, and then one more battery then the system will be where I want it to be. Ultimately, we all want unlimited power! And I have the space for the panels, so I see more in my future.
  2. Thanks both of you. This query is for someone else - The person in question is hoping to exchange his utility payment for a monthly solar payment. I agree with both of you, I personally think it is a terrible idea in most circumstances. But if this is the avenue he wants to persue, then I at least want to introduce him to a qualified company that wont do him in. My system was bought cash and works well. And I have no loan repayments to detract from the enjoyment of the system. When there is good sun, I have 'free' electricity. More importantly, when the skies are grey, I don't get that si
  3. To add to Vassens post, the inverter will power non essential loads on grid side, however, You can specify the discharge or power from the battery in System mode. I've set mine to 1.5 kW, so even if someone were to switch on the oven (yes, the oven needs to go) the inverter will only draw 1.5 kW from the battery, and the rest from the grid.
  4. Exactly what branderplank posted. His batteries seem to be full at around 11h00? So there is probably plenty of room to handle more storage. With mine you can see the battery reached full SOC at some time after 15h00. I don't have enough solar for more batteries. In fact, I'm a little bit short for what I have, so the array needs to grow before I can add anything more to storage.
  5. The easiest way to see if you could squeeze more power out of the panels is to monitor the production graph. If the batteries are full or close to full the charge will stop or slow down. It is very obvious on the production consumption graph, when solar production falls down and tracks consumption, thats when the batteries are full or close to full. If you're consistently full at lets say 10h00 in the morning, you have a ton of spare solar capacity. However, if your batteries only reach 100% late in the afternoon, for example 15h30, then you probably can't add another battery to your system un
  6. I can recommend Aspergo. I bought a couple of Dyness batteries from them. Exceptional service.
  7. Any series panels should ideally face the same direction. In a series configuration, the current out of the string is determined by the panel with the lowest output. So if the panels facing one direction are in the shade, or bad light, then power of the whole string will drop. When I laid out my panel configuration I drew a too scale drawing with all the panels. Perhaps consider the same and see if panels with smaller dimenstion might not make better use of the space. There are many ways to orient and position the panels relative to eachother. Perhaps once you have something to sca
  8. Any decent rent to own solar companies out there? If possible the type that tries to match the solar install payments to what your municipal payment would have been.
  9. Nice install. What kind of information are you not getting from the Solarman app and web site? The only thing I found missing was detailed information regarding power utilisation for UPS, Aux and grid output. Other than that everything the inverter does is logged on the portal.
  10. Also, we installed a Bosch gas stove and oven combination. It works a treat, and uses electricity only for the igniter and oven light.
  11. We've had the geyser on the timer now for a few weeks. I also added a thermal blanket to assist in reducing losses at night. I am sure the situation will change a little bit in winter. As it is now, the geyser kicks in at 08h30 and shuts down again at 10h00. This is to allow other loads, washing, drier, etc, to get priority. At 12h00 the geyser kicks in again and is disconnected again at 15h30. The geyser was also turned down to 60C. It has dropped consumption to about 5 kWh per day from between roughly 7 and 10 kWh per day. That was a side benefit, the main problem addressed here
  12. I have an API key from solarman for my plant but time has been a bit elusive the last few weeks. The plan is to use the additional information from the inverter, such as state of charge and production to determine when I switch on and the geyser. The pool pump will also be scheduled according to how much power is available on the day.
  13. Thats exactly what I want to do, lower the power draw in the early morning, and late afternoon when the sun is no longer at its peak. The total power used will be almost the same, the only difference is I wont be using the battery along with solar for that first 30 to 60 min in the morning and later afternoon geyser top ups.
  14. Did you happen to take note of the change in voltage between warm and cold panels? Here you get almost 15% more power, so presumably this gain is split between voltage and current increase. It will be interesting to see how much this can increase the Voc so we get an idea of how much room we need to leave so we never hit the inverters max voltage.
  15. 1. So far the system works very well. I still want to change the geyser element for a smaller one, if only to reduce the current draw when it comes on at 08h30 so the little bit of solar is enough to cover the geyser element. Even though a heatpump can save a few kWh per day, it works well enough as it is that we will reevaluate this winter to see if we need to improve on it. 2. The electric stove / oven combo was replaced with an all gas Bosch. My mother is very happy with the new unit and the savings are awesome. And I am very impressed with the temperature control of the gas oven, some
