PARALLEL CONNECTION FOR INVERTERS AND BATTERIES
Afternoon all. Some help required please. Getting really frustrated with conflicting instructions from the manual and installation videos.
1 - Diagram below shown in the installation manual for inverters in parallel calls for installation of circuit breakers on the AC cables and DC cables for each inverter, however the videos say that you must not install individual circuit breakers?
2 - Diagram below shows the installation diagram for multiple batteries connected via a busbar to the inverters and shows individual fuses for each battery. The videos also say that these must not be installed?
3 - Silly question, but the communication cable between the inverters from master to slave, does the connection go from parallel A on the master to parallel A on the slave or to parallel B on the slave?
I have installed 63a breakers on grid and load (one on each in my distribution board) and have used 10mm cable. I have not used a double pole breakers as all the neutrals are common. I have 63a double pole breakers in my board that has my changeover switch for grid and inverter.
