Low temperatures reduce the activity of the LiFePO₄ batteries. A To avoid deep discharge and to protect the battery, you should at least 30–50% battery charge as a reserve. In case of heavy snowfall, it is even advisable 70%in order to have sufficient capacity at all times.
✅ A sufficiently charged Jupiter C Plus storage remains functional and safe even in frost.
If a Jupiter C Plus power storage has not been charged for a long time – for example due to snow-covered PV modules or poor lighting conditions – the discharge should only take place when the battery is over 90% charged This protects the battery from voltage drops and extend the lifespan your storage system.
Since photovoltaics produce less energy in winter, you should Jupiter C Plus storage Do not use it with many power-intensive devices at the same time. Avoid high discharge currents, especially if the charging input is restricted by snowfall or diffuse solar radiation.
Tip: Use the storage primarily for basic devices such as routers, refrigerators or lighting – this way your Balcony power plant efficient and reliable in winter.

Sounds plausible – thanks for the tip!
But where can I set the app so that it stops supplying power once it reaches a certain threshold – or rather charges the battery instead of feeding it into the house?
Unfortunately, the app is very spartan when it comes to setting options.
