Test conditions and notes6

1.Efficiency, AC regulation and THD are tested by 75% load, linear load at 25Vdc/50Vdc/400Vdc input voltage.
2.All parameters not specified above are measured at 25Vdc/50Vdc/400Vdc input and 25℃ of ambient temperature and set to factory setting.
3.The tolerance of each voltage value by models is: 224→±0.5V; 248→±1V; 2380→±5V.
4.The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
5.Saving mode only activates when the unit is used independently and the RPL switch is in the ON position.
6.During withstand voltage and isolation resistance testing, the screw "A" shall be temporarily removed, and shall be installed back after the testing.

FAQ

What does the Mean Well NTN-5K-148CAN combine in one unit?

This model combines an AC-DC charger, a DC-AC true sine wave inverter for the load, and an AC bypass function for the load in one enclosure. It is designed for 48V battery-based systems and provides 110V AC output. That makes it suitable for applications needing inverter operation, charging, and UPS-style power continuity from a single device.

Is the NTN-5K-148CAN a true sine wave inverter?

Yes. The NTN-5K-148CAN provides pure sine wave AC output with total harmonic distortion below 3%. That is a key differentiator for loads that require cleaner AC power quality rather than a rougher waveform.

What are the main power and output capabilities of this model?

The model belongs to the 5KW NTN-5K series, but it is rated for 4000W continuous power, 4600W for 3 minutes, 6000W peak for 10 seconds and 8000W surge for 30 cycles. It delivers 110V AC output by default (100/110/115/120V selectable). The built-in charger is rated up to 3600W.

Can the NTN-5K-148CAN be used with different battery types?

Yes. Mean Well specifies this model as compatible with both lead acid and li-ion batteries. That gives buyers flexibility when matching it to existing or planned battery storage systems.

Can multiple NTN-5K units be expanded for higher power systems?

Yes. Up to 6 units can be paralleled on the AC output with built-in active current sharing; total output current must not exceed the rated current per unit x number of units x 95%. Three NTN-5K units can also be configured for 3Ø 4-wire output, and two 148 units for split-phase 1Ø 3-wire.

Is this inverter suitable for demanding temperature environments or enclosed installations?

It is designed for a wide operating temperature range of -30°C to +70°C, subject to the derating curve. Working humidity is 20% to 90% RH non-condensing. The unit is also vibration-rated to 10-500Hz, 3G along the X, Y and Z axes.

What monitoring and control options are available on the NTN-5K-148CAN?

This model includes Modbus-RTU over RS-485 and CAN bus communication for monitoring. It also has built-in remote ON/OFF control through a front-panel dry contact interface. For more advanced system control, optional intelligent controllers such as the CMU2E and CMU2E-R are available separately.

What protection features are built into the NTN-5K-148CAN?

The unit protects the DC input against reverse polarity, low voltage (alarm at 44V, shutdown at 38V) and high voltage (alarm at 62V, shutdown at 66V). On the AC output side, it provides short circuit, overload, and over temperature protection, plus a 50A circuit breaker. These safeguards are intended to protect the inverter and connected system during abnormal operating conditions.
