  1. I'm sorry, didn't read the entire thread before I posted above. It is already discussed and I would like to add some basic PV knowledge. The max. PV power is the maximum power that the inverter can draw from the panels. So if your panels CAN produce more than that, they just won't because the inverter cannot take more out of them. Compare that to a 2 kW heater that you simply plug in the wall, the inverter powering the outlet can make 5 kW max so will your heater blow up due to too much power? No it will not. It'll take just the 2 kW. So does the inverter work as well, it cannot take more out of the panels than it can use, even if the panels are able to produce more. This phenomenon is called clipping. So you cannot take the max PV power in account as you do with the max voltage. Don't go above that voltage and calculate what the voltage will be on the coldest day you can expect on the location. For the max power you connect I think what is said already 20 to 30% is ok. No need for more, clipping will take the most of the profit.
  2. The inverter can handle 450 VDC so make that 2 strings of 6. Furthermore if there is place on your roof you can go 7s as well. Inverter will clip a little but you will have more power earlier and longer. Furthermore: batteries. Lots of them!
  3. What possibilities do you have when you put your inverter in PYL mode? Guess it will automatically fill in the right values.
  4. He already gave you the answer. Pylontechs are 15s LiFePO4 batteries
  5. Yes, should be a nice solution. You can connect the BMV to ICC and let it talk to your inverter.
  6. Nice setup Wim! Your questions: Why do you want to bond neutral with earth? Preferably a separate earth stake since it is lightning protection so you don't want to let the lightning rush thru your entire system. Same as 2 Are you going to use an optimizer for that shaded panel on in your north east array?
  7. I have been told about a year ago by MPP Solar these where discontued. @Jaco de Jongh has a story about these here on the forum about this special type Infini. There where many that had lots of problems with the super 4k especially when parallaling them. When did you get your inverters? And did they do their job ok so far? Sorry I can't help with the question about unbalanced load. Maybe @Youda or @Coulomb can.
  8. Hi John, welcome to the forum. Please help me understand what the question is. If it is, is this possible, yes it is. Yes you can but you have to fill in your charging voltages manually. That's how I would do it but it is depending on your loads.
  9. Stefan maybe you made a bit of a unfortunate choice. The Infini 5k plus like @Youda's off grid lab and I (among others) have would be more convenient because of its parallel capabilities. You can start with one like you do now and add more inverters later. But anyway the 5,5k is also a very nice inverter. What type of grid connection do you have? 3 x 25A? That is a hell of a nice backyard you have there!
  10. Furthermore we have recently purchased a 5 year old Volvo V60 Hybrid. It has a 11 or something kWh battery on board and we charge it every day from empty to full. The wallbox is now on the AC output of the inverter and is the only load on it. Today I commisioned the wallbox but it was not that sunny but it gave more than enough to charge the car direct from solar. The car will draw 3500 W max. Highest peak in solar I saw was 5.500 W while charging and the rest pushing back which means that the inverter can do more that 5 kW. Hope this will end the clipping or at least reduce it. When the car is at home during day that is... Here are some picks from the build: The rain gutter was doing nothing and on that part of the wall should the wallbox come. So I fixed that first and came to the conclusion Swambo didn't like it. So now it became more like a makeover instead of just hanging a wallbox on that wall. This is what it looks like now, she is happy and so am I. It works like a charm!
  11. The inverter is still in grid-tie mode and doing well. Problem is it is clipping a lot. It can feed back only 5 kW but there is 9.240 Wp connected. I'm building a battery as I told already but it is not going that fast due to lack of time. Here is a sneak preview: The upper space is reserved for the electronics in which the BMS of course plays the most important role. Cells are 206 Ah each, nominal voltage 3,22 Volt. That will give me this 16s3p configuration. So 16 x 3,22 = 51,52 Volt nominal. 51,52 x 206 = 10,6 kWh x 3 = 31,8 kWh in total.
  12. That's what I'm doing as well at the moment. You can read more here. About your plans concerning the 18650 batteries I was on that course as well. Learned a lot from secondlifestorage. AFter a while I came to the conclusion that it was simply to much work and changed plans. Now I'm still building my own DIY battery but with new LiFePO4 cells. Questions: - Are you planning to feed your entire house with solar and battery? - How much PV did you connect to your inverter?
  13. Hi Stefan, can you tell us a little more about your current PV system? Just curious, especially for the powerwall. Gruess, Rik
  14. Hi Antony, is this floor heating a pure resistive load? That is a LOT! Why do you heat this way for god-sake? And what is your source? Eskom, inverter? Have a nice weekend, Rik
