Do you have a question about the DPM10 and is the answer not in the manual?

Hello, I have a DPM30 on my lorry. I've not had any issues with it and was using it in the day time but in the night I turned it on and it blew 2 internal fuses. I changed these, wired it back in (correctly) and soon as i turned it on (no load on the inverter to poelwer anything) it blew the 2x 25amp internal fuses again. I've shown in the image which side the fuses are. After I changed the fuses I moved the unit away from anything metal and tried again. As soon as I press the power button it pops the fuses.

The internal fuses on the EDECOA DPM10 inverter could blow when powered on due to:
1. Reverse polarity connection – If the inverter is connected with reversed polarity, the fuse will blow to protect internal components (for models with reverse polarity protection). In models without this protection, internal parts like electrolytic capacitors and MOSFETs may burn out.
2. Input voltage exceeding limits – If the input DC voltage exceeds the allowed range (e.g., above 15.5V for 12V models or above 30V for 24V models), internal components may burn out, causing the fuse to blow.
3. Short circuit or excessive load – Connecting a load that exceeds the inverter's rated power by 120% or has a short circuit can cause the fuse to blow.
To avoid fuse damage, ensure correct polarity, proper voltage range, and avoid overloading or short circuits.
