  1. Looking for a Raspberry Pi 4 4GB or better to purchase in Cape Town for running Home Assistant and Homebridge on Pop me a message if you're selling one.
  2. Thoughts on the requirements of blocking diodes for different panel orientations?
  3. That is another option albeit involving quite a bit more capital input...
  4. We have the following off-grid setup for our small Airbnb in a remote location: 4x JA Solar 365W Panels 1x Kodak OG-Plus 5.48 Inverter 2x Pylontech UP5000 Batteries The current panels are on a north-facing roof. We are wanting to install more panels of the same kind (so that we have 10-12 in total). The problem is that we only have space for 1 more panel on the North-facing roof. The inverter only has one MPPT input. We have the following options: Option 1: Keep 4 existing on north face in series. Add 8 new on East face in series. Parallel these two strings together at MPPT directly. Option 2: Keep 4 existing on north face in series. Add 4 new on East face in series. Another set of 4 new in series on East face. Parallel these three strings together at MPPT. DC Combiner box required? Option 3: Add 1 panel on north face to make 5 panels in series. Add 5 on East face in series. Parallel these two strings together at MPPT directly. Which of these would recommend? Or would you recommend something different? Would we need blocking diode on each string before the inverter for shading due to different roof orientations?
  5. There is no grid connection (it is completely off-grid). The battery therefore provides all the power required when no solar input. The power that battery will need to provide, is that the apparent or actual power?
  6. We have the following off-grid setup for our small Airbnb in a remote location: 4x JA Solar 365W Panels 1x Kodak OG-Plus 5.48 Inverter 2x Pylontech UP5000 Batteries We should have a very low power usage (LEFs, energy efficient fridge, no stove, gas geyser (battery operated), etc) however we use approximately 300W/h or about 7.2kW/day. We are trying to figure out why we have such a high usage as we use approximately 40% of our batteries overnight (sunset to sunrise) which just doesn’t seem correct. When monitoring the system on watch power, the apparent power is very high compared to the actual power, as shown below as an example reading: AC Apparent Power: 207VA AC Actual Power: 40W Load Percentage: 4% Any idea as to what the issue may be?
