Small solar advice (5KVA hybrid system)

Here is 6kW sizes. From cheapies on left to fancy right. Cant really put navasolar as they dont have a 6kW. Trying to find off-grid ones only even though I added the Lux there which they say has a CT, not sure why labelled off-grid. Price was competitive, so I threw it in

The bigger inverters. I didnt vet which ones can export on the big ones to be honest. But we all know exporting is a waste of money in SA. The price difference is quite humungous. Someone like me would go for the Ecco or MUST. Someone more interested in the refined Axpert features, the Luxpower. Now I dont know what the Deye and Sunsync has that makes it cost that much. The Lux seems to be the best middle ground for most

even the cheapies can export (unless off grid) - shoo i guess prices shot up since i last checked
there are a lot of settings and featured you get with a deye that you may not get with Lux

I say may because ill give lux a plus they have been pushing a lot of features -
i wont even say deye is great because of local support (because they are even mailing then in china you get quick responses) but i hear Lux Sa is great in support

not rally the right 6kw to compare as the deye is an off grid hence way cheaper but ya you looking at a 6/7k cost difference

looking at the 2 @wingnut771 provided would be similar .

as for why the huge price difference been looking at my neighbors one so comparing what i can find to mine
Deyes AC pass through is higher (30ish amps)
The AC/DC blending, Aux/gen port (smart load) and ct clamp i mentioned earlier
the ability to power loads not on the inverter from excess PV without feeding to the grid
The software control Time of use so you have a bit more granular control (though i like the deye has that grid boost function where you can for emergencies force the grid to charge the batteries - while on deye you can as well but its like a 2 step process that you may need to undo after)


I see also Deye is IP65 rated and Lux IP20 so deye can be placed outdoor and less sensitive to dust , seems the lux doesn't have internal lightening, leak , arc fault detection / protection etc pr- deye is almost double the weight and size so the components size and manufacturing come into play
warranty on deye is 5 year and Lux is 2


So tldr if you just want basic functionality and dont need anything extra go luxpower - but you want the extra features go Deye

(lol like buying a car - both will get you on the road but the cheaper may not be as comfortable, feature packed or fuel efficient)

Well on the new one with ct clamp. Pair with luxpower battery you can push the 5 year to 10

i see that one has the smart load as well - nice

nice to see their stuff is improving

Looking at just replacing my sna6000 with them. Mainly because of the dust issue like you said

In this particular case it's 1C vs 0.5C
So I'm guessing that when running on battery only the power available will be restricted to 5kW.

Would personally buy 2 Dyness 10kWh batteries to get 20. Then you still have the "1C" capacity since they are in parallel vs 1 FW.

I was comparing off-grid inverters, not the ones with the CTs. Threw the Lux in there as it was very competitive at the price and as users say, it actually has a CT. But at 9k for the off-grid Deye, its not badly priced I must say compared to the cheapies. Was just referencing what you said about the prices not really being that much different.

Also the Deye Wingnut referenced is a fanless one if not mistaken like what the OP is buying so not like for like. Compare the fanless Lux with that specific model. IP65 and Fanless already puts it in a different league.

lol i was conceding on that fact :) it does cost a lot more
 
Got the quote back for a Deye 5kw inverter| Deye 5kwh battery | 6 x 580w bifacial.

I think I might be able to squeeze one more thing, either another 6 panels to make it 12 or an extra 5kwh Deye battery. Suggestions?

Leaning to the 12 panels because it seems easier on paper to add batteries or upgrade the inverter in the future.

Any chance you can go for a 6kw hybrid inverter and add your geyser and then add more panels? What was the quote actually like?

Batteries help extend your time off grid. Panels can always be added

Could probably get a bigger Luxpower instead of the Deye, but I don't think it will be enough for a geyser too without compromising on the current 65c target on a 3kw element that makes sure there's no Legionella.

R81k for Deye 5kw, 5kwh Deye Battery and 12 panels.
He also quoted R126k for a Deye 8kw system with 3x5kwh Deye batteries and 15 panels.

He was upfront about his prices in the beginning about being a bit higher as he makes extra sure all his stuff is compliant with earth point, trunking etc.

Are you at home during the day to make use of the solar? Better get extra battery so you can maximise solar production.

You know that legionella likes standing water between 20 to 45 degrees, generally your geyser doesn't hold water long enough to allow it to grow if you're regularly using the water.
65 degrees is overkill, 60 is ideal but anything over 50 is fine.
