Hi All, 

Looking for advise and assistance please

On the verge of taking the solar plunge 

Some background info on consumption. 

House uses about 24kws per day, we spend about R2000.00 per month on electricity, its prepaid and bought through a person that supplies the estate electricity, so a bit more expensive I think then municipal. 

One electric geyser and it uses a timer, not sure if this helps?

I am looking for a 8kw system and probably 20kw batteries with 12 solar panels. I have been told the roof is a solar installers dream, as it’s north facing with enough space for installation. 

I have been quoted on a sunsync system with batteries, a deye system with LVTOPSUN batteries and a sun sync system with Greenwich batteries. 

All of the quotes are in the ball park of R260k - R280k 

My intention is to move as much of the grid as possible and only use Eskom when necessary.  

Which of the systems would be the best (I assume the full sunsync system?) is 20kw of batteries overkill? And is the pricing correct? 

Many thanks 

 

 

I think you would need to specify the items.

It does sound like 8kw inverters but we cannot be sure.

Also, the battery + panel specs makes a huge difference.

Apologies, yes you are correct 8kw inverter

 

batteries quote on are 2 x 10kw batteries 

 

Panels 12 x 540W panels

I would say R260k sounds fair.  However, Brand does influence the price by a couple of thousand.

Deye and Sunsynk brands are equivalent. Cannot comment on Lvtopsun, not familiar, but can you confirm model numbers of all the batts?

20kWh of 0.5C batteries are okay if you are leaning towards going more off-grid. 10kWh of 1C batteries are okay if you want a bit of loadshedding backup, and want to shift loads around to daytime and to Eskom's non-LS times to help cope. Basically, more batteries, more independence.

LVTOPSUN is a new Chinese kid on the block reaching our shores. They have panels, Inverters and Lithium batteries. The batteries look very generic and advertise to be 1C. They also mention Inverter comms support for Deye etc. The pricing is very good. Looks to be another Felicity Lithium battery type of contender. Time and opportunity will judge the quality.

The inverters I have seen are only 24V 3kW and look like a Voltronics Clone. To be honest Magnetos 10kWh Lithium battery and the LVTOPSUN look like a rebadging exercise, however, I dont expect any of these 2 parties to be OEM. They just buy the dam thing and ask the manufacturer to place their marketing on them pre delivery. 

The prices are affordable same as the felicity units: R51k for 10kWh unit. Consider that a freedomwon 10/8 is at R77k. Thats a huge lot cheaper if its an apple for apple in terms of energy density and discharge rating. 

Please someone roll the dice...Very fascinating, Id love the opportunity to test this battery and hook up some diagnostic equipment on it to gauge.

Hi there, 

just to provide an update, installed the following this weekend. 
 

1 x 8kw Sunsync inveter

3 x 5kw Greenwich batteries

12 x 555w longi panels

 

seems to be working great so far, will share pics soon. 
 

really appreciate all the comments.
