  1. I tried getting the firmware updated but it was never updated. Why can't one just load a file to the inverter and update it yourself? Still have the issue. Perhaps others can comment if this is how it is supposed to work?
  2. It has been doing that since I remember. I normally discharge during the night so the odd time I do keep my batteries full, I noticed it. I requested a firmware upgrade but never get any feedback. Did request an upgrade again last night. Can you fast track it?
  3. I was wondering if someone on the forum had the same issue. My Sunsynk 8.8kw unit draws about 40-48watts when on grid and there is no PV. So basically I have disabled the timer. When on 100% charge, it goes down to about 93% over night. At 48V and ~45w, that is a constant 1A draw from the inverter. Is this normal? The grid supplies the rest of my load. Not sure why the Inverter would draw this small amount when grid is available? I have disconnected my battery one evening and the next morning connected it again and the SOC was at 100%. I have 3x US5000 Pylons. I could not find a similar case on the forum.
  4. Ability to change a few settings via MQTT would be great.
  5. I also opted for the 455w panels. Can install a max of 10900w on the 8kw Sunsynk with losing a few watts due to max of inverter. I was never aware that exceeding the current rating of the mppt is a non-issue
  6. Which 5v micro controller can be configured with Tasmota? Would be great if I can still use a small board like the NodeMCU or Wemos. What do you use for smoothing?
  7. The proportional SSR (also called phase angle controller) is something that not many are familiar with. This unit can control the current to a resistive load by varying the input. The input can be either 0-10VDC, 0-5VDC or 4-20mA. This is a wonderful device since it can switch on at any time during the sine wave. See the picture of the wave forms. This effectively limits the amps to the load. I have tested this successfully on my geyser and old incandescent light bulbs. I know of 2 brands, Celduc and Crydom. I have a Celduc one at home. They are expensive though. I think R2000 for the Crydom one via RS components. With my Sunsynk inverter I would like to utilize this device to heat my geyser when there are excess PV available. Here is what I want to do: Using a Arduino board with a DAC I can set the reference on the SSR. I want to monitor my power from grid usage using Home Assistant and use that to control the reference on my SSR. That way on cloudy days I can send as little as 100w to the geyser element. The problem is that I do not know of any micro controller that has a 0-5V,0-10V or 4-20mA output. I have played a bit with the Nodemcu on HA. Does the community have any ideas on how to reference a 0-5V or 0-10V while monitoring the inverter power?
