I had some bad weather lately, but here are 2 days from my brother's place in Jhb. On the east facing MPPT he has 6 x 550 panels with approximately 35 degree elevation.

May 4, 20242 yr Author Back to the original topic. I have set up a sensor for the internal power (W), as well as a Riemann Sum helper to calculate the energy usage (kWh). Images below will show both, and it's not good. I can confirm though that it increases with "activity". It scared me to see energy consumption similar to what my 200l Geyser used
May 5, 20242 yr Author Just te be clear, I agree it is not only internal consumption, but rather a combination of consumption and losses. Still, it refers to power and energy lost due to using the system. Also, these numbers used to be smaller before upgrading firmware. Edited May 5, 20242 yr by PappaB Spelling
