Ok some feed back . my roof is a bit of a mess and we had to put 5 panels east and 5 west facing. I decided to ad a further 6 panels on the car port facing north. so 16 panels total.

yesterday i made 6kw from the sun at 11. Thus far everything in the house can run of the sun during the day. Yesterday had aircon on for the entire day.
Batteries seem to last through the night. Although i think i need to add 1 one more battery.

Busy fine tuning the system but i am extremely happy. The company installing was amazing. Painless installation and looks amazing.

Now looking forward to all the money i wont have to pay eskom. Based on my rough calculation system would pay it self back in 3 to 4 years.

Lol The North panels shoud have been the first and the East/west should have been the further :)

you will probably see better performance in the coming days and months so you might think you don't need the extra battery - but we all noticed the significant drop in winter this year so if the battery price is good do it.

TOU settings and Smartload on the DEYE are your best friends that will help get that years down (lol Eskom price increases will help too :) ) but 3 to 4 years sounds really great already

Nice, just make sure if you in CT that they are one the CoCT approved inverter list.

A friend got a Huawei inverter recently installed that for some reason is not on the CoCT's list.

Now he's trying to deal with the bureaucracy to get that sorted.
 
What hap

What happens if it not in the approved list but purely a backup solution?

Only thing I added to my two is a couple of fans pushing air up from the bottom. I used this thingiverse design:

Deye 5kw Fan Unit by nate_syd

The Deye 5kw hybrid gets REALLY hot, adding fans will keep it much cooler (~10deg) - which will ensure that it has a much longer life span with less thermal stresses.This box will enable you to mount 2 x 92mm PC case fans underneath the heat sink.Print, drill holes for the screws & you're...

3D printed Deye 5kw Hybrid Fan Unit - SUN-3.6/5/6K-SG03LP1-EU

The Deye unit gets hot! when running - to the point I couldn't hold my hand on it. This doesnt go well for longevity - drying out caps & degrading their life (Arrhenius equation) So i've been running some 120mm fans just plonked on top - but now i've made a fan shroud/unit that can be put under...

Just don't bolt them on as this guy has done - use contact adhesive to glue velcro to the side of the heatsink and attach them that way, works brilliantly.
I added this temp controller to have the fans turn on at 48 C and off at 42 C: https://www.robotics.org.za/XH-W3001-12V

I don't find the 8Kw getting hot -
Fans sound like 747 at take off when they switch on but seem to keep the unit cool

That right there is the reason 8kw owners put their own silent fans onto that unit.

My Sunsynk 8kw silence hack

Hi Everyone, Thought I'd share this because I have noticed a few people concerned or frustrated with the fan noise from the 8kw Sunsynk inverter. I couldn't install my inverter in the garage because I do a lot of woodwork in there and I know the dust would cause issues in the fans and heatsinks. ...

As mentioned above, 5.5kw has no fans - that's why it's IP65 rated, so the added fans do help a ton.

I connected up some silent fans to keep the built in fans from going on so often.

Hi guys, absolute noob here. What happens if the load is more than the pv supplied? Will the battery power kick in or what happens?

Sorry if not enough info supplied.

Depending on setting, it will either pull from battery or the grid.

Thanks Achmat, at this stage I have issues with my grid power as the solar system trips the eskom power, so will ask the installer if it's set to use the battery when going over. Or can I see it myself somewhere?

Depends on your inverter settings (and what inverter) some will use battery to supplement and if not enough it will swap fully over to grid or others will try and blend all the sources

This is not correct no matter what inverter - it should not trip Eskom no matter what even if you swap it to use battery you still have the base problem
what inverter BTW?
