Q&A:
Q1: What is an on-grid inverter?
A: A device that converts DC solar power to AC, synchronized with the grid. Excess energy feeds back to the grid; no battery storage required.
Q2: How does a on-grid inverter work?
A: Uses MPPT to optimize solar input, converts DC to AC, and synchronizes with the grid. Excess power exports for credits (net metering).
Q3: Any Certificates?
A: Yes. G99, VDE-AR-N 4105/VDE V 0124, EN 50549-1, VDE 0126/UTE C 15/VFR:2019, RD 1699/RD 244/UNE 206006/
UNE 206007-1, CEI 0-21, C10/11, NRS 097-2-1, EIFS 2018.2, IEC 62116, IEC 61727, IEC60068, IEC 61683, EN 50530
Q4: Safety features?
A: Anti-islanding (grid outage shutdown), surge protection, overvoltage/current safeguards, and temperature monitoring.
Q5: Ideal applications?
A: Commercial/industrial buildings, factories, farms, and small utility solar projects.
Q6: Maintenance needs?
A: Minimal—dust/weatherproof design (IP65), remote diagnostics, and firmware updates reduce physical checks.
Q7: What is the warranty?
A: We can supply 5 and 10 years long time warranty.
Q8: Can it work during blackouts?
A: No—anti-islanding safety shuts it off unless paired with batteries (hybrid inverter).
Q9: Future upgrades?
A: Supports integration with energy storage (ESS) or smart grids for hybrid functionality
