How Change Fuse/Circuit Breaker in Quattro 3kw on AC1-Out?
Question: I have a 220v boat with 3kW Quattro. I recently experience a power surge from my shore power and now I can’t get shore power on my boat.
The manual seems to suggest that when one has an overload situation and Charger is not working, one should replace fuses/circuit breaker from AC1-Out or AC2-Out. However, the manual does NOT specify how to change them or how to locate them ( which fuse is for AC1-Out and which is for AC2-Out.
Background: My shore power comes in via AC1-In and my Genset comes in via AC2-In. I know that manual stipulates Genset should be on AC1-In and AC2-In is for shore power. The previous owner installed Quattro and it works so I didn’t change it. We had no problem with Quattro until now.
After the power surge, the inverting function of Quattro still works and Genset charging via AC2-In also works. However, the shore power does NOT.
Our actions: We disconnect the AC1-In wires (ie live neutral and earth) and did voltage test and we saw 240V so we are confident that current flow from the dock to Quattro. However, once we connect the 3 wires back to AC1-In, no shore power.
We even move the 3 wires in AC1-In (Shore Power) to AC2-In Connection and still no shore power.
We also move 3 wires in AC2-In (Genset) to AC1-In as stipulated in manual. We were surprised to find when we did this, Genset also CANNOT charge.
Once we moved Genset wires to AC2-In connection then Genset can charge the battery and produce 240 AC for the boat.
Based on above, can you confirm that:
1) Is changing fuse/circuit breaker on AC1-Out is the right remedy?
2). If so what is the procedure to locate and change the fuses? What are the proper fuse size? 250 ah? (3000watt/12V).
