Good Day, my question was actually, what the formula is to calculate the battery DOD at 40%. As per below, it does not reflect what you are getting.

Hello, Thank you for your inquiry. The maximum charge and discharge power of a battery system is limited by either the inverter or the battery storage unit. We will contact the manufacturer, Deye, and ask them to supply the missing SUN-10K-SG02LP1 battery systems. For comparison: The SUN-10K-SG01HP3 battery systems have a maximum charging power of 13 kW and a maximum discharge power of 11 kW. Consequently, the SUN-10K-SG02LP1 battery systems would have a maximum charging power of 16 kW and a maximum discharging power of 11 kW.

Hallo, vielen Dank für deine Nachricht. Rechts neben dem Diagramm "Ertragsprognose mit Verbrauch" findest du den Button "Zur Tabelle wechseln": Die Abregelung am Einspeisepunkt wird in kWh pro Monat ausgegeben:

Dear Sharjeel, Thank you for your inquiry. When creating a new inverter dataset, you typically face the issue of not knowing the inverter's efficiency curve, as it is not published on the datasheet. On May 29, Sungrow updated the SG125CX-P2 and added the new SG125CX-P3. Which inverter are you missing? Please provide the exact model designation or send us a datasheet. We will then contact the manufacturer to request that the information be added or updated.

Dear Mark, Thank you for your message. For lithium iron phosphate batteries, the reference value used to calculate discharge cycles is based on a DoD of 40%. This results in the following factors for the discharge cycles: DoD Value 0.2 2.206563 0.4 1 0.6 0.598166 0.8 0.397315

Any feedback yet on the formula?

Dear Mark, Thank you for your inquiry. The house connection, electrical service connection or grid connection is the interface between a building's electrical installation and the power supply grid. It consists of the service entry cable and the service connection box.

What does the "House Connection" mean in the cables layout

Good Day, when calculating Max Charge and Discharge Power in the Battery Setup, do you use the Max Battery Voltage (60Vdc) of the Inverter or the Max Operating Voltage (57.6Vdc) of the Battery multiplied by 220A in this example below?

Thanks, please share with me as soon as you get that formula.

Hi, I have a query regarding addding new inverter to the system. Whenever I have done this, my system production reduces than the other inverter I'm using. Take it as example. I am using 125kW Sungrow string inverter. One is already in PVSOL database and I tried to add a new updated version of it in PVSOL. The moment I selected it, my production got reduced as well???? I'm looking forward to hearing from you soon. Kind Regards, Sharjeel

OK, aber der Fall mit der Abregelung am Einspeisepunkt ist ja alltäglich. Wie kann ich den Wert quantifizieren, das muss doch irgendwo aufsummiert werden und nicht nur in einem Diagramm dargestellt werden? Ich muss doch wissen, wieviel Energie durch die Einspeisebegrenzung "verschenkt" wird. Wo finde ich den Wert?

Dear Mark, We apologise: for lithium iron phosphate batteries, the reference value used to calculate discharge cycles is not a DoD of 60% (as with lead-acid batteries), but a DoD of 40%. You can simply enter these four values manually: We are still awaiting feedback from our development department regarding the formula.

Any feedback on my post?

Hello, Thank you for your inquiry. We confirm that in PV*SOL premium 2026, you can only generate new climate datasets using Meteonorm 9 data. However, you can continue to use your own climate datasets based on Meteonorm 8.2 data for simulations. If you select a custom climate dataset based on Meteonorm 8.2 data from the drop-down menu in PV*SOL premium 2026, the simulation will be performed using Meteonorm 8.2 data. Unfortunately, we are not permitted to integrate multiple Meteonorm versions into a single version of PV*SOL premium. We obtain the data from Meteonorm and have no control over the data itself; we simply integrate it into PV*SOL premium. Therefore, only the current Meteonorm 9 version can be used in the current version of PV*SOL premium 2026. If you wish to work with Meteonorm 8.2 data, you must use PV*SOL premium 2025 R10. We have sent you an email with the download link. Before doing so, you must uninstall two applications: both PV*SOL premium 2026 and MeteoSyn. If you wish to use PV*SOL premium 2026 on a second computer, you can transfer the Meteonorm 8.2 data from the first computer to the second by importing the WBV files from the directory "C:\ProgramData\Valentin EnergieSoftware\MeteoSyn\WBV\_userfiles\ZAF" into PV*SOL premium 2026: Any project file (*.pvprj) started in PV*SOL premium 2025 R10 can be opened in PV*SOL premium 2026. The climate dataset based on Meteonorm 8.2 data will then be automatically added to the list of available climate datasets in PV*SOL premium 2026.

We are currently on Meteonorm 9.0, is it possible to run a simulation using older Meteonorm 8.2? When I select the attached my simulation still runs using Meteonorm 9.0.

You have to be in the "Object View" - Tab to see this right-click option. It does not work in any other view, especially "Module Coverage", which confused me in the beginning.

Dear Haydn, Thank you for your inquiry. In the hourly simulation, hourly generation and consumption values are simulated and compared, and the self-consumption rate is determined from them. With a generation of 800 kWh and a consumption of 1,000 kWh, self-consumption in that hour is 100%. In the minute-by-minute simulation using half-hourly consumption values, minute-by-minute generation values are compared with half-hourly consumption values. No minute-by-minute consumption values are generated.

Dear Mark, Thank you for your inquiry. The commas must be removed. Please find enclosed the CSV file we have edited. Wannie Zorzetto Load Profile VAL.csv

Hello, Thank you for your inquiry. You can activate the roof surfaces by right-clicking --> Activate. This switches the view from terrain to object mode, allowing you to place panels on the roofs. This YouTube tutorial explains the activation process at the 05:00 mark.

When I try to change the value at 60% DOD to 10000 and do the Calculate cycles then that value just returns back to the values that it was. Nothing changes. Also please give me the formula to determine a batteries DOD at 60% from the datasheet.

Hello, I am completely new to the software and struggling with FAQ and first steps. Successfully created a testing environment and created multiple houses but the software will only let me place solar panels on the ground and not on roofs. Probably something really simple but neither Google search nor FAQs could help. How do I tell the software that I want to place solar panels on roofs? Sorry this probably sounds really stupid and I am not a native English speaker. Just really frustrated after multiple hours into test project and search and not being able to find a solution ... THANK YOU for your help!

Thanks for your response. Is the self consumption calculation as simple as if 800kWh were generated and 1000kWh consumed in 1h, then self-consumption is 100%? If yes, then this will always overestimate self-consumption, as generation & site demand are not usually fixed at a given power for 1h. Within that hour there are likely to be periods when generation exceeds demand, and self-consumption will be less than 100%. If I select 1-minute simulation, but I have only input half-hourly data, will PVSol synthesise minutely consumption data? Thanks, Haydn

Good Day, I am trying to load a customers Day Profile but I am getting this error. Please assist. Wannie Zorzetto Load Profile.csv

Dear Haydn, Thank you for your inquiry. If you select multiple load profiles (whether imported by you or built into the program), they are aggregated into a total consumption figure for the simulation. In the hourly simulation, the self-consumption share is calculated for every hour of the year by determining what percentage of consumption can be covered by PV energy. Hourly simulation is the standard. However, when importing load profiles, you can also import data with 1-, 5-, 10-, 15-, or 30-minute intervals and then run the simulation on a minute-by-minute basis to obtain more precise results.
