MEAN WELL A302-2K5-B4 is a 2500 W rated modified sine wave DC-AC power inverter for a 24 VDC nominal battery supply. It provides 110 VAC at 60 Hz through 2 USA TYPE-2 receptacles, with a front power switch, status indicators and temperature-controlled fan. The RC-2500 remote ON/OFF controller is an optional accessory ordered separately.

Match the load to the modified sine wave output and the complete model’s fixed voltage, frequency and receptacle arrangement. The surge rating is a transient capability, separate from the rated output.
The 5000 W surge rating is separate from the 2500 W rated output. Select transient loads against the manufacturer’s operating limits.
DC Input and Efficiency

Select the battery supply, conductors and load together for the rated DC current and permitted input-voltage range. A301 identifies the 12 VDC input version; A302 identifies the 24 VDC input version.
Protection
| Battery low alarm |
21 ±0.8 V |
| Battery low shutdown |
20 ±0.8 V |
| Overload threshold |
>2700 W |
| Overvoltage protection |
30–32 V |
| Overtemperature threshold |
60 ±5°C / 140 ±9°F |
| Fuse rating and quantity |
15 A × 12 |
Overload protection shuts down the output voltage; re-power the inverter to recover after removing the overload. Output short-circuit protection shuts off the output. Reverse battery polarity opens the fuse.
The overtemperature threshold is a protection value, distinct from the ambient working-temperature limits. Follow the actual operating-temperature and loading limits when sizing the installation.
Operation, Cooling and Environment
| Ambient working conditions |
0–25°C at 100% load |
| Working humidity |
20–90% RH, non-condensing |
| Storage temperature |
−30 to +70°C / −22 to +158°F |
| Storage humidity |
10–95% RH |
| Temperature coefficient |
±0.05%/°C, over 0–50°C |
| Cooling control |
Fan ON above 40°C at the NTC |
Green indicates power ON, yellow indicates overtemperature protection, and red indicates overload protection. Battery-voltage and current meters are also provided.
Use the local ON/OFF power switch or the specified optional remote controller. The temperature-controlled fan and its airflow path must remain unobstructed; the NTC switching value does not extend the permitted ambient-temperature range.
Dimensions, Connections and Mass

The DC input uses the positive POS+ and negative NEG− stud connections shown in the mechanical drawing. Two M8 studs are shown at 60 mm spacing, with a 23 mm projection. The specification lists no supplied DC connector/cable; select suitable battery leads and terminations for the application. Do not reverse input polarity.
The catalogue body dimensions are 430 × 210 × 159 mm. The mechanical drawing also labels a 450 mm mounting dimension, a 160 mm bracket dimension, 119 mm slot spacing and a 19 mm front receptacle projection. Use the complete drawing to determine the installed space and mounting arrangement; keep the fan airflow clear.
The PACKING entry gives 8.7 kg as the catalogue reference per unit (8.7 kg; 2 pcs / 19 kg / carton). This reference is not a measured shipment weight.
