SMA Energy: Does SMA Energy work offline?

SMA Energy systems can continue generating electricity offline, but remote monitoring and cloud-based optimization through SMA Sunny Portal require internet connectivity. If communication fails between devices, inverters reduce output power to 0 percent as a safety fallback.

Source
SMA Energy: What is the maximum system size for residential installations?

SMA systems typically support a maximum residential configuration of 18.9 kWh battery storage, which is suitable for most single-family homes but may be insufficient for larger properties or commercial applications.
