Battery inverters off-grid system

RSANZ · Monday at 10:27 AM2 days

If I analyze the same off-grid system—with the same PV array, the same consumption, and the same PV inverters—but change the battery configuration from 1 to 2, the fuel consumption is 11,000 liters in the first case and 20,000 liters in the second. How is this possible? Furthermore, the configurations shown on the screen do not reflect reality; since both are three-phase inverters, only one battery inverter would be needed—not three—but the software does not allow me to change this. 1) 2)

Panel integration tool (snap alignment) very intermittent

Ryan PSE · November 3Nov 3

Hello, I am having an issue with the tool which snaps the panels into alignment with existing panels. Previously this has always worked fine, I drag the panel nearby to an existing array or panel and it will show the grid and then show the dialogue to confirm I'd like to snap the panel into the array - but since the latest update it's been very temperamental, most of the time not working or the grid only comes up for a second then disappears. It makes moving arrays around difficult and hard to g

I have 2 scenarios in a photovoltaic installation 1) 500 kWp + 1 MWh BEES 2 500 kWp + 2 MWh BEES Self-consumption is 67.5% for option 1 and 69.7% for option 2, with an energy self-sufficiency rate of 78.7% and 80.4%, respectively. With the production of both being 792,857 kWh In the first option, 257,778 kWh are fed into the grid. In the second option 240,005 kWh are fed into the grid. How is this possible, given that in the first option there is surplus photovoltaic energy once the batteries

MPPT search modes: Local vs Global and adjustable scan interval in PV*SOL

MPPT search modes: Local vs Global and adjustable scan interval in PV*SOL

Temur · October 21Oct 21

Dear PV*SOL Support Team, I would like to clarify how PV*SOL models local and global maximum power point tracking. So far, I have only been able to run the simulation with a one-minute time step, and my understanding is that the global maximum power point is determined at each step. Could you please confirm whether this interpretation is correct? In practice, an inverter may track a local maximum between periodic global scans, with scanning intervals of, for example, 10 or 30 minutes, depending

Hallo, gibt es irgendwo eine Schritt-für Schritt-Anleitung, wie ich mit Pix4D ein 3D-Modell erstellen kann, das ich in PV-Sol einbinden kann? Freundliche Grüße Ludwig Brokering

Battery inverters off-grid system

Hello,
Thank you for your inquiry.
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, as described here.
Feel free to send us your project files (*.pvprj) to hotline@valentin-software.com so that we can take a closer look at it.

Panel integration tool (snap alignment) very intermittent

Hello,
Thank you for your message.
We have not made any changes to the program in this regard, and we are unable to reproduce the error.
Updating your graphics card driver might help.

Hello,
Thank you for your inquiry.
It appears that, in your project, doubling the battery capacity does not contribute noticeably to an increase in self-consumption.
Please send us your project file (*.pvprj) to hotline@valentin-software.com so that we can take a closer look at it.

It's not on a specific pvprj it's just on all projects for me.
Thanks
