Off-grid System

[Oliveira]

Good afternoon,

I have a question, I am currently configuring an off-grid system with and without a generator, I am applying a hybrid inverter in this case "Huawei 5Ktl- L1" and batteries also "Huawei LUNA2000-(5-30)-S0"
Since the inverter is hybrid, I do not need a battery inverter, however the program always shows me the option with a battery inverter...

This is due to the fact that the program does not have the capacity to read a hybrid inverter or is me doing something wrong? 

All the toturials and videos I watch don't use hybrid inverters so I didn't find much help.

Thanks

Hi Oliveira,

no, you are not doing anything wrong. This is a question that is asked quite often since it is admittedly not very clear in the GUI. Please find an answer here:

Kind regards,

Hello. Configuring an offgrid system with PVsol is impossible. How come it has not been fixed ? Any support from PVsol ???

Hello,

Thank you for your inquiry.

On the "System Type, Climate and Grid" page, you can select the "Stand-alone PV System" (with and without a backup generator) system type. Planning stand-alone systems in PV*SOL is based on the SMA Off-Grid Configurator program, which we originally developed for SMA. This program contains the design rules that SMA has specified for us. These rules cannot be changed or deactivated. For example, only systems with AC-coupled battery systems can be planned; DC systems are unfortunately not possible. We understand that these rules may not necessarily apply to other manufacturers and may entail further limitations.

For greater flexibility in component selection and improved transparency during the planning process, we recommend that you initially plan your stand-alone system as if it were a grid-connected system:

1. On the "System Type, Climate and Grid" page, select a grid-connected system.
2. Set the feed-in limit to zero; then no energy will be fed into the grid:
   
3. The value under "Total consumption covered by grid" indicates the energy that cannot be covered by the PV system. This energy must be provided by the backup generator or (if you are not planning on a backup generator) "approach zero".
