What surge protection is needed for X1-Smart G1?
Install SPD Type 2 on DC (inverter end) and AC (main supply point). For VP >1100V, add SPD Type 3.
-
Is an external RCD required for X1-Smart G1?
The inverter has an internal RCD. If local regulations require an external RCD, use a Type-A 300 mA model.
-
What cable size is required for AC grid connection of X1-Smart G1 inverter?
Use 8–10 mm² for L/N and 4–10 mm² for PE. For 8.0 kW models in 220V grids, use 8 mm² for L/N.
-
Can I install the inverter of X1-Smart G1 outdoors?
Yes, it has an IP65 rating for outdoor installation. Ensure it is protected from direct sunlight, rain, and snow.
-
What is the difference between models ending in "-D" and "-N" for X1-Smart G1?
"-D" models include an integrated DC disconnect switch, while "-N" models do not. An external DC switch

How does the "GMPPT" function mitigate shading losses and what are the scanning mode trade-offs?
GMPPT (Global MPPT) actively scans for multiple power peaks under partial shading. Modes: Off (no scan, no shading), Low (scan every 4h, minimal shading/power loss), Middle (scan every 3h, moderate...
-
What are the potential consequences of incorrect "Meter Direction" setting?
If the physical meter/CT is reverse-connected but Meter Direction is left at default Positive, the inverter will misinterpret import/export data, leading to incorrect Export Control behavior and po...

What is the AFCI (ArcCheck) functionality, its self-test procedure, and fault clearing options.
The optional AFCI detects DC-side arcing (IEC 63027). Arc Enable turns it on/off. Arc Self Check (done in Normal state) verifies module health (ARC Test Succeed or ArcSelfFault). Arc Clear: Disable...

What is the function of "Earth Detect" in X1-Smart G2 settings and what happens if it's enabled and grounding is absent?
When enabled (Settings > Functional Settings > Earth Detect), the inverter checks for a valid ground connection. If grounding is absent, the inverter reports an EarthFault (IE:1601) and will not op...

Can you describe the operational difference between "Soft Limit" and "Hard Limit" in Export Control or General Control. in X1-Smart G2 settings?
Soft Limit: The system attempts to control output to the set value but won't fault if exceeded. Hard Limit: If the output reaches the set value, the inverter disconnects from the grid and re...
