: Never connect the power supply to the output terminals ( U, V, W ), as this will cause immediate equipment damage. Jte Inverter Manual
No. Jte inverters have internal DC fuses that, if blown, often indicate a major internal fault. Opening the case exposes high-energy capacitors that can remain charged for hours. Always contact an authorized service center. | Error Code | Meaning (from manual) |
Proper wiring is vital for operational stability. Always disconnect input power before starting work. Standard Specifications (Typical 380V Models) AC 380V 3-phase (-15% to +10%) or 220V single-phase MPPT Range 450VDC–750VDC for 380VAC models Output Frequency 0–50Hz/60Hz Overload Capacity 150% for 1 minute; 180% for 10 seconds Key Wiring Rules: | : Never connect the power supply to
If your inverter displays an error, it is likely protecting itself from a dangerous electrical condition.
The manual clearly separates analog and digital terminals. Applying 0-10V to a digital input (rated for 24V max) fries the optocoupler.
