Series Overview

Model Rated Power Input Voltage Output Voltage
A301 300W 12V DC / 24V DC 110V AC / 230V AC
A302 300W 12V DC / 24V DC 110V AC / 230V AC
Applications: Ideal for portable power systems, RVs/campers, remote off-grid monitoring, and essential backup power for emergency lighting or communication devices.

Operation Guide

Ensure correct system installation to maintain the longevity of both the inverter and the connected battery bank.

Consideration Recommendation
Input Source Ensure the DC input (12V or 24V) exactly matches your battery system.
Load Sizing Calculate the peak power (surge) of your loads, not just the continuous rating, to prevent overload shutdowns.
Cable Sizing Use high-gauge cables to minimize voltage drop between the battery and the inverter, especially at high loads.
Safety Note: Ensure proper ventilation around the inverter's cooling vents. Never block the airflow path, as this will trigger the over-temperature protection circuit.

The F3 suffix selects the 230 VAC, 50 Hz output and the TYPE-3 European receptacle arrangement shown above. Match both input and output ratings to the intended equipment. The 200 W figure is the surge rating, not the normal load rating. No surge duration is specified for this model. Check that the connected load is suitable for a modified sine wave supply.

A quantitative overload trip or automatic restart characteristic is not specified for this model. Remove the cause of a short circuit or reverse-polarity connection before returning the inverter to service. Do not assume automatic recovery from a protection event unless it is explicitly stated above.
