Hi Guys

We are upgrading my house to an 8kw Sunsynk unit

 

I have a few questions, while I did read the forums the is no direct answer 

 

1. What is the maximum length for the CT coil, I was told not exceed 13m, current distance is 22m what options or workarounds do I have ?

2. Earth Neutral Bonding when Eskom is off ? What exactly needs to be done for this ?

3. Are there any other special requirements such as surge protectors etc other than having double pole breakers and EL in front of the load ?

4. The non essential side of things, anything to note ?

 

The inverter will replace a growatt which is covering one phase on my 3phase house

 

Thanks in advance, sorry for noob questions but the sunsynk is not as straight forward as other installs and I want to do it the correct way  

1. 22m, I'd think is not a huge problem, just ensure you have reasonably thick conductors for the bulk of this distance, so you have little to no losses, else the reading from the current transformer could be off by an unacceptable amount for it to work accurately.

2. You'd need a relay that can be activated by the inverter, once the input AC power disappears, this relay, on the output side of the inverter needs to connect PE (Power earth) with N (Neutral) on the UPS/Output side of the inverter.

3. not sure, I don't have any, someone else is sure to educate both of us... 🙂

4. no power there, until eksdom returns...
