Hi folks. I'm hoping someone can clarify something for me. I'm just about ready to start wiring up a sub DB board for a Sunsynk 5kva inverter & battery backup combo. I've heard conflicting information from different sources regarding the use of single pole (phase and earth) and double pole (phase, neutral and earth) SPD's in terms of the correct format to use. Also, I understand that I need surge protection on the grid to inverter feed as well as the AC output of the inverter to essential loads. In a lot of the sub DB's I've seen I usually only see one SPD in either double pole or single pole format. Are you not meant to use a seperate SPD after your double pole MCB between grid to the inverter as well as a seperate SPD once again after your inverter AC out MCB to feed your essential circuits? Unless in these examples they're using an SPD after the main DB mains MCB feeding the inverter "In" MCB. If someone can clarify this for me I'd be grateful.

Hi guys, I'm new to the forums, officially at least, as I've been browsing as a guest for some time and gaining a lot of valuable information in the process. I'm finally looking at taking the plunge and purchasing an inverter/battery backup system as a first phase approach to stick it to Eskom but the one thing I'm having trouble reconciling is the cost to install these systems. I totally understand that we all need to make money and I understand the concept of supply/demand but good grief most installers/electricians seem to be taking the p&ss with their installation fees. I'm not an electrician or electrical engineer but have a pretty good fundamental understanding of electrical/electronic circuitry and components. I know that I could do the installation myself and that I could get a registered electrician to pass a COC but my question for those who have done so is how do you get around registering your warranty for the hardware? In my mind, provided the installation is done to code and a COC is passed, surely the warranty should remain valid for the hardware? I'm interested in purchasing a Sunsynk 5kva hybrid inverter and pairing with a Hubble AM2 battery. If there's any thoughts, advice or even suggestions on the matter it would be much appreciated. Thanks folks!
