Some basic questions from another newbie ...

Featured Replies

Hi all,

Just starting out on this journey so have some catching up to do.  At this stage looking at a Sunsynk 5kw unit and battery, with solar later.

To start with, I hope to get some guidance on the following:

-    I have three phase supply but plan to hook up just one phase to the inverter.  From what I have read, this would be OK – let me know if I’ve missed anything.

-    Are there any regulations regarding placement of the battery and inverter- either directly or indirectly?  I see nothing in the gas installations regulation.  There is an AS/NZ standard – any ideas on where SANS stands on this?

-    The distance from Inverter to DB board will be about 15meters (5V drop at 40A and 6mm2 cable).  Apart from the CT cable, anything to worry about?  Will I need additional breakers?

-    Regarding adding a battery later, is it just a matter of adding a new one or would I have to throw out the old one and install two new ones (same make / capacity / age)?

-    I notice that some of the inverter manufacturers also have batteries.  Are there any pros & cons when it comes to matching vs mixing brands?

That's it for now, thanks.
