Hi Frederik, thanks for reaching out! I sent you the project via private message. If I was supposed to post it here instead lmk.

Hi! We are writing a thesis using PV*SOL and need help ASAP We have designed a grid connected PV system (7 roof tops) with a li-ion battery for energy storage. For our first simulation we used 4 battery packs of XOLTA 79kWh/30KW. For the next simulation we reduced the buildings energy consumption drastically due to installation of heat pumps, the solar radiation is the same and we still used 4 battery packs but this time we get a negative battery loss. What does a negative battery loss mean?
