Solar installers and suppliers

[Zuluzebra]

Yup, same. I'm looking to get a third battery installed but can't seem to find stock anywhere. My installer also told me he doesn't know when stock is even going to be available.

Let me know if you find any though.

we found stock. Final price came to 191k.

Sounds similar to the setup I want to go for. I received approval today so want to start getting some quotes. Who was yours from?

Why are these panels not suitable?

Amps way too high. Operating current (IMP) on 600W Canadian"s are over 17A, 5kw Sunsynk is limited to 13A. Yes, some believe the inverter will simply "clip" the extra, but long term that can't be good for your inverter and will cause heat issues.

Inverter will just clip above the 13a.... Its wasted

"Larger" panels not recommended for a 5kw inverter by Sunsynk themselves. Someone posted this correspondence in the Sunsynk Users & Installers Facebook group:

Hi there, looking for some opinions on this quote i have.

I'm looking to get my 2 bedroom apartment backed up for load shedding. the load in the apartment is low, even the geyser is a gas water heater. the company spec'd a 3.3kw inverter with 2 Lithium batteries, advising this would be adequate to keep the house and most appliances operational during a shed.

Any opinions on the sizing and price would be appreciated. not sure if this is overkill, or if the brands are decent.

If your cooking appliances aren't on the inverter then 3.3 kW is more than enough.
Once you start plugging in things like microwaves or airfryers, you might run into issues.

 

[Wild Cape]

If you want to pay crazy markups for the exact same kit as everyone else for no good reason at all…sure.

I can second Somewatt Solar.

so what is the alternative currently ?

Actually received a quote from them today based on 12Kw 3 phase inverter etc - R558K !

And naturaly why pay for 600w panel and only get
Edit 458w

out of it, then you can save money and buy

Edit 455w panels


These would actually be better suited to lower voltage mppt with the 2x (10x6) arrangement

455w half cut 11.02amp and 41.3v

While I fully agree with you, the argument is that you will get the 450W for a large period of the day with the bigger owner l panel. You will lose peak production, but still have larger total production for the day

The amps according to lab tests , indicate from start to peak a rather flat line and then drop of at voc

So if the current is always limited by the controller to 13a

You will allway get 76% of what is being produced right through the voltage rage

I do agree with you on this portion

Sure if the controller allows more amps until it hits its max watt and then throttles down to 13A as the volts rise

Then you would have a wider boob graph as you would gain in the hours pre and post peak

ie like your 4.8kw on a 4kw example

So a guinea pig would have to observe the behaviour

Why does everything have to be a flipping argument with you?

 

[Hotfuzz]

Thoughts? Also, anyone familiar with converting to prepaid in CoCT? I currently pay a home user charge which is currently R370 p/m so would love to get rid of it.

It isn't an argument

It is just pointing out that we can make deductions

That fall in grey areas

And without knowing the devices exact behaviour

It could go either way

Is this graph from a sunsynk 3.6kw?
The dc current is that the pv current or the mppt charging current?

I Don't live in cape town

Can tell you the new regulations laid out by nersa for municipalities

Mean that even on prepaid you get levy on your bill if your connection is over 20a

Even on prepaid , i am on prepaid and pay a levy

If you have 3 phase it is way more as you pay per phase per amp/10amp if i recall correctly (salt)

If over 20A connection

If you go prepaid then the fixed charge still appears on your bill.

Don't have my latest bill to hand at the moment but I think it's a hair under R200. Then each account will tell you how much prepaid you bought this month but it's basically just an FYI thing, it won't actually reflect as an amount payable.

Good to know. My home user charge last month was a third my electricity bill which is really sad.

Area dependant

They are reprogramming the prepaid meters / changing the breakers that supply your home

To the amp you select if you select lower ie to limit levy amount

And also reprogramming for the token limitations that is now getting close to the end on older devices (salt)

If you have prepaid the meter auto connects after x time

If breaker you would be without power until they come out to switch on again (don't know if this nuisance tripping incurs a charge if not prepaid) (salt again)

So once they have replaced the breaker it would be wise to replace main breaker to be less ie 40a if that is what you selected

It may even be regulation
To avoid them having to switch on your breaker on the distribution box , cause you overloaded the connection
(Salt i am on prepaid so no idea how the post pay is handled)

The sunsynk that can have this current limited means that you can select the 20a connection and have batteries supplement

Means you could select 20a and pay no levy

But then you pay the highest fee for the units purchased

ie the levy payers pay a lower rate per unit

But with the levy it avg out closer to unit price you would have paid on old system ie just price per unit

But where you fall on usage can mean you pay a bit less and some a bit more on avg

ie like a tax bracket that you are just under or over
