September 16, 20223 yr I am electrically challenged so please excuse me if this is a dumb question I only got space in my DB for 1x2 pole breaker. From what I understand for inverter wiring there must be 2 breakers, 1 for each direction DB->Inv Inv->DB Must they be 2 pole breakers or is 1 pole ok? Do they have to be installed in the DB? ie could they be installed on the inverter side Obviously I would get an electrician to do the install, just wondering what the options are..
September 18, 20223 yr If you have no space in your DB you can mount a small surface DB next to your main DB. Normally you would need a double pole change-over switch to switch between inverter and utility. Than you need a feed from inverter and a feed to inverter breaker, these can be single pole as the change-over switch is already a double pole. You also need indication lights to show there is alternative power to the DB. In my case I installed a bigger DB because it normally does not look good when adding more DB’s to make space for other breakers.

THere are also 13mm wide MCB's that you can use to replace each 26mm wide normal AC MCB's. This can free up space.
