I would like to use 3 Multiplus II 48/3000 120V wired in parallel in my vehicule for educational purpose and public demonstrations. As I understood, the neutral to earth bonding should only be made at one point in the system. This means only one Multiplus will switch its ground relay, the others (slaves) will be disabled. Is that correct?
Since this protective bonding must handle a default current corresponding to the total installed inverter power, in my case, the internal relay should handle continuously :3x3000VA/120V = 75A.
The maximum number of devices in parallel specified in the datasheet is 6, so in reality one ground relay may handle up to 150A...
Can you confirm that the internal ground relay supports these currents?
Thank you for a helpful answer.
Best regards
Priscilla
