Dear Mark, Thank you for your inquiry. Since you cannot enter 8,000 cycles at 70% EOL (DoD), enter 10,000 cycles at 60% EOL (DoD) (and have the remaining values calculated).

Good Day, I want to make sure if my calculations are correct. I added a Dyness PowerBlock Max 16kWh battery to the database. Please just check if my Discharge Cycles are correct below:

Dear Mark, Thank you for your inquiry. Your ridge is not centered. Consequently, the roof pitch is 22 degrees on the south side and 25 (or 27) degrees on the north side. If you have a symmetrical roof, check the box for "centered." If you change the roof pitch, the existing configuration will unfortunately be deleted.

Dear Mark, Thank you for your inquiry. Unfortunately, that is not possible. Your only option is to run the simulation twice—once with and once without the non-essential loads.

Dear Mark, Thank you for sharing the project file. Consumption does not take place only between 12 noon and 4 pm, but between 7 am and 7 pm. On a sunny day in November, a month with high levels of solar radiation, demand can only be met by solar power (including the battery) between 8 am and 6 pm. Electricity must be drawn from the grid for one hour in the morning and one hour in the evening. The battery is charged within an hour (8–9 am) and discharged within an hour (5–6 pm). With a usable capacity of 4.6 kWh, it is far too small to cover evening and morning consumption (before sunrise). The battery capacity would need to be increased approximately tenfold to ensure a high degree of supply security even in June, a month with low solar radiation. Excluding non-essential loads, the small 4.6 kWh battery is, of course, sufficient to cover essential loads. We have sent you the screenshots from the diagram editor by email.
