Intelbras IONIS-15K T4-220V AFCI and IONIS-20K T4-220V AFCI
On Grid Solar Inverter
The IONIS-15K T4-220V AFCI and IONIS-20K T4-220V AFCI are state-of-the-art solar inverters for grid-connected photovoltaic systems. They are fundamental for the efficient conversion of direct current (DC) energy generated by photovoltaic modules into alternating current (AC) at parameters suitable for connection to the local electrical system.
These inverters offer safety and robustness in a high-performance package, featuring:
- AFCI - series electric arc detection and interruption
- IP66 protection rating and C5 anti-corrosion grade
- Solar Plus platform for energy generation monitoring via App or Web
- High efficiency
- 10-year warranty
*DC voltage to AC voltage inverter, microprocessor controlled.
