One large inverter or several smaller ones
Several inverters spread the risk of a fault and suit roofs split into sections. One larger unit means fewer devices to install and monitor. Both are common; the datasheets show the MPPT count and input limits that decide it.
Grid type
Most European sites are 400/230 V three-phase. Some series are built for 220/127 V low-voltage three-phase grids — check the grid type before you choose.
Export limits and monitoring
Where the grid operator limits export, an energy meter lets the inverter cap feed-in. A data logger connects the plant to Deye Cloud for monitoring.
