Dear Alphagen, Thank you for your inquiry. Hybrid inverters can usually be combined with a variety of battery sizes. The manufacturers who enter their products in our database often do not enter all possible combinations. Which battery size (battery capacity) would you like to use together with the SUN-5K-SG01HP3-EU-AM2? We can contact the manufacturer and ask for an update. Alternatively, you have the option of creating a missing battery system yourself. We recommend that you copy an existing database entry (right mouse button --> Copy), make the desired changes and save the data record under a new name.

Dear Filly, Thank you for your inquiry. The information on the ‘Battery system’ page is a recommendation based on the load profile data and is intended as a rough guide. The simulation of the battery system only takes place with the simulation of the overall system. The battery system can only be optimised after the overall system has been simulated. You can find more information in our online help and here. The HTW recommendation is based on this study (unfortunately only available in German): Optimale-Dimensionierung-von-PV-Speichersystemen_Quaschning.pdf

Hallo Rares Cosma, vielen Dank für deine Anfrage. Die Reihenschaltung der drei Strings durch Parallelbetrieb von MPP1 und MPP2 ("Betriebsart: MPP 1+2") ist nicht möglich, weil die maximale Leerlaufspannung von 1100 V mit 1350 V deutlich überschritten wird: Diese Verschaltung ("Betriebsart: MPP1, MPP2") ist möglich, wir weisen aber auf die Mismatch-Verluste aufgrund der beiden unterschiedlichen Ausrichtungen am selben MPP-Tracker hin, sofern du keine Optimierer einsetzt:  

Hallo Hausdach, vielen Dank für deine Anfrage. Bitte sende uns die Projektdatei an hotline@valentin-software.com, dann sehen wir uns das mal an.
