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.

Dear pero159, Thank you for your inquiry. In the inverter configuration window, specify that you want to connect two modules in series each.

Dear Hannah, Thank you for your inquiry. PV*SOL premium files can only be opened in PV*SOL (Standard) if they are purely 2D designs, i.e. if the “Use 3D Design” box has not been ticked on the “System Type, Climate and Grid” page:

I hope you do not mind me joining this discussion, as I am facing a very similar challenge and would greatly appreciate any guidance from those with more experience in this area. I am currently designing a PV system in PV*SOL using the following components: Power optimizer: GNETEK Honeybee1600-HPLC — a dual-input optimizer capable of handling two solar modules per unit Inverter: SAJ CHS2-50K-T6-X All-in-One Hybrid ESS — 50kW, 6 MPPT, three-phase, transformerless My issue is that PV*SOL appears to assign one optimizer per module by default, which does not reflect the actual capability of the Honeybee1600-HPLC. I have reviewed the optimizer database settings but could not find any option to specify that this particular unit supports two modules per optimizer. Could anyone advise whether there is a setting or workaround in PV*SOL that allows the software to correctly recognize a dual-input power optimizer? Any guidance on how to configure this properly would be greatly appreciated. Thank you in advance for your time and assistance.

Hi, why is the Inclination showing 27° when my Roof Pitch/Angle is set 22° My Installation is Flush Mount as per below:

Hello, We would like to purchase a license for PV*SOL Standard. Occasionally, we receive files created with PV*SOL Premium. Is it possible to open PVSOL Premium files in PV*SOL Standard? Thanks in advance. Hannah

Good Day, How do you change the Roof Pitch or Roof Angle without deleting any configurations? And also, why is the inclination not the same as the Roof Pitch when my system is setup for flat roof mounting?

Good Day, How do you indicate in the project setup which loads are Essential and which are Non-Essential Loads? I have created two different Load patterns but do not know where to indicate which one is Essential and which one Non-Essential for the system to use in the calculations.

Thanks, I sent the Project now.

Thanks. Ok I have made it as per below for 90% DOD

Dear Mark, Thank you for your message. We confirm that you have correctly configured the battery system. For LFP batteries, please define the charging strategy as follows: The values within the green box are not relevant in this case (for LFP batteries) and will not be taken into account. However, in the red box, the DOD (Depth of Discharge) is defined in percentage terms. If the system allows for a full 100% DOD, leave this value at 0%; otherwise, enter the difference here (100 – DOD in %)—for example, for a 90% DOD, please enter 10% here. The usable capacity is calculated based on this value.

Dear Mark, Thank you for your inquiry. You can watch our webinar recording. The financial analysis is explained starting at 01:00. Further information can be found in our online help section.

Thanks. I have created one already as per below. Just check below if all settings correct please. Is there a place where you can set the DOD?

Dear Mark, Thank you for your inquiry. We confirm that you have selected the correct system type (Grid-connected PV System with Electrical Appliances and Battery System) and the correct battery system (featuring DC intermediate circuit coupling, in accordance with the circuit diagram). Although your preferred battery system (Deye 20K inverter with 5.12 kWh battery) is not currently available in our database, the Deye 20K inverter with 20.5 kWh battery system is available. You can copy this battery system and reduce the number of batteries per string from 4 to 1.

Dear Mark, Thank you for your inquiry. Roughly speaking, daily consumption amounts to 100 kWh. The PV system generates 43,247 kWh per year. Assuming an even distribution of solar radiation throughout the year, this would correspond to a daily production of 118 kWh. However, since the distribution varies significantly by season, it can be assumed that less than 100 kWh will be produced during the winter months. The energy storage system compensates only for daily (not seasonal) fluctuations; therefore, it is likely that energy will be drawn from the grid during the winter months. You can use the Diagram Editor to view the specific times at which energy is drawn from the grid (red line). If you wish, please feel free to send us the project file (*.pvprj) at hotline@valentin-software.com, and we will take a look at it.

Good Day, Are there any videos or illustrations that will help me understanding the Financial Analysis part in detail. I am struggling to understand this. Regards

Good Day, In the project I have created, why will there be power supplied form the grid if there is enough Solar Power. I have activated the Daily profile so that only load is drawn from 12h00 - 16h00 but does not make a difference. Is there something I am missing?

Good Day, on this topic I just want to confirm; if I have a Hybrid System with PV Solar and Battery connected to the same inverter as per attached, must I select the following System Type? For this Hybrid system, must my configuration be as below if using a 20kW DEYE 3Phase Hybrid Inverter with a DEYE 5.12kWh Battery? In the database I have created the following Battery System. I have used the same Inverter in the Battery System as per the Main system:

Dear Umresh, Thank you for your inquiry. Net Metering As with the surplus feed-in, the electrical energy generated is primarily used for self-sufficiency. The unused electricity is fed into the power grid via a double-tariff meter and offset against the electricity purchased. The tariff counter rotates backwards. If more solar power is generated than consumed in the billing period, the surplus can be carried forward as a balance to the next billing period. Enter a price for directly marketed electricity (Price of Electricity sold to Third Party) Use the button to select a Net-Metering tariff from the database The selected tariff is valid as standard from the date of commissioning of the PV system For further information see Net-Metering Tariffs Choose a price change factor (Inflation Rate for Energy Price) You can find more information in our Online Help.

Hello - I need help in the net metering module. As my saving exceed the total bill. Please help to explain how this work? Thanks Umresh

Hello, Thank you for your message. You can try this—for example, using the "Time-Controlled Charging/Discharging" function. However, the software is not optimized for this specific use case.

So I can't simulate a battery system, even with minimal photovoltaics, that charges and discharges to the grid?

Hello ! Im a old user if PVSol and I can't use the actual version with my perpetual licence of PVSOL (bought in 2018). Is it possible to have a link to the version with which I can use it(or another solution), please.
