If you want to add a solar pv geyser in Cape Town you need a SANS2 and 4 form filled out by a "competent person". For solar thermal geysers you just need a plumbers letter. I am exploring the idea of prefeeding a gas geyser with an Elon100 system. Where do I find someone to sign these forms though, the only electrical engineer i know who signs off most of Cape Towns PV installs doesn't do geyser PV systems. The building inspector is adamant i need these forms even if i run the elon 100 in offgrid configuration which would obviously make it 100% energy efficient

So for a new build i am ordering a 2x15way board for essentials, a 2x15 way for non-essentials, and 1x18 for solar and the electrician is going to build them in and lay conduits etc so no trunking Are those boards big enough or should i get bigger?

If money is tight get a trolley inverter and run a few extension cords Dont consider anything other than lithium as my sole experience in gel batteries resulted in a total write off after 90 days

Do you have hourly stats you can share comparing the bad times to a normal yield?

Is there not supposed to be a 10cm gap between the panel and roof or is that just for tiles or is that just hearsay?

Where is it stated that you get a 15 year warranty on the battery when used with a Sunsynk? I tried to google it and can't find anything?

I was watching a random solar documentary on the US and they were installing products with 25 year warrantees. Most of our products sold here don't come with anything near, most inverters only offer a 5 year warranty with a handful offering 10 and many stories on forums suggesting they don't honour them and blame the user/installer/location/weather etc So are we being sold inferior products here or are we just not getting good enough warranties. If you are paying all this money for a system including now engineering signoffs you would expect the system to be warranteed for a long time else you are wasting your money, imagine every five years having to repeat these large payouts, this scenario is very possible given solar is a very recent mass phenomena in SA and are just a handful of years old, and most of the products on the market are new/untested and sadly many already have a whiff of won't be honouring any warrantees. Maybe I am just a being stingy skeptic but I don't think a five year warrantee is good enough for anything requiring professional sign offs that i have to pay for because my government can't supply me with electricity

Other than Victron does anyone else make a reasonably priced 24v NRS certified inverter Given I already have a 24v battery and don't need more as long as I am grid connected a 24v NRS inverter would make great sense for me

Roof is a 35 degree pitch

Where on this roof is the best place to put some panels, at this stage i don't know how many I want, if grid tied about 5 probably, but if offgrid then 10. The DB is by X. I was thinking 5 would fit nicely by the red and that might be my best location but is it and where is the next best location if I want to add more. And if I wanted to cover my roof with panels where are the best locations? The area in front of the cobbles is flat roof and a future proposed version of estate rules does not allow panels there so best to avoid. I was also thinking on a pergola over the cobbles but that might run into hassle with the muni as pergolas cant be covered without signoffs due to structural concerns [wind etc]

As in even if you fed it from the hot line the water in the pipes would still be cold and by the time it has pulled in 8 liters it has only just gotten warm? i.e a waste of time?

If you have n0 Eskom connection on the property I would like to hear what tech you using, any data you have to share around daily generation, dealing with winters etc. Any lessons learnt and tips you have? I use so little power that I am considering it, but winter remains an issue.

Does anyone have detailed data comparing the two. On my Sonoff 63a I can see the dishwasher uses 0.7kWH per wash on eco mode How would that change if i fed it from a hotwater line? My washing machine used 0.2kwh on 30 degrees, a dishwasher seems way more energy inefficient given it only needs 10l of water and a washing machine around 50 iirc

I would have thought one would just use a dedicated charger attached to a multiplug connected to the generator. Though if you dont have one then it might be very useful indeed

Just wondering what sort of installation costs you looking at. Assuming I buy the Elon 100, 3 panels and mounting kit, what sort of cost am I looking at for balance of system and installation with COC? I saw elsewhere on the forum a guy was quoted 20k excl panels to install 2 panels and that is a no go for me.
