I’m building a new home and initially planned to add a 150l indirect evacuated tube geyser as well as a gas geyser. I always planned to add PV and now I’m beginning to think that just having 2 geysers (150 an 100l) on PV might be the better route. The bathrooms are at opposite ends of the house, hence 2 geysers. I’m not sure how the SANS 10400-XA regulations apply in that case because it stipulates that 50% of water heating must come from other than resistive heating? If anyone has knowledge of how these regulations apply, I’d be interested to hear about it. It looks I’d save around 20k on the solar and gas geyser setups, which I could use towards an inverter.
In any case, if there is an exception for SSEG installs I’m looking for a grid tied inverter. I have space for 8 455W JA solar north-facing panels. I’d like to add backup at a later stage. I’ve had a look at the Sunsynk 5kW but it looks like it will clip the DC current at 9.9A which will lose me some power production. I then came across the Solis RHI 6k 5G which seems like a great inverter at a great price. Is there reason not to go for this inverter?
I’m in Stellenbosch municipality but power is provided by Eskom, if that has any relevance.
