Mike's (non-Sunsynk) System

Deye is pretty much Sunsynk without the new firmware AFAIK.
That 8 hits the sweet spot for an average household IMO.
How noisy are those fans? I decided to go with the 5 because of IP65 rating as I'm near the beach... and the lack of big fans...

Snap and snap. I'm installing the 5KW inverter and 5.1KW LBSA battery on my stoep on Thursday as a base of the system which I'll do over a period of time, and have been a bit worried about the fan noise as it's a nice quiet space. But install options are very limited due to the layout of my very old (1860) house, and it's a deep stoep and dry so we decided to organise a box as soon as it's installed which looks like a bit of furniture, with appropriate ventilation etc.

How's that fan doing so long Mike? And looking great btw.

So everything is running off my system now and it hardly comes on. When it does, it's probably for 1-2 min. It sounds like a PC or Xbox Series X when they're under load.

Just put the kettle on now to test.

The load jumps from 1.61kW to 3.52kW but even that didn't seem to kick start the fan. It seems pretty random.

Would recommend you find a spot where it's out of sight if the randomness is going to bug you, or go with the 5kW inverter...
 
How do guys get this graph to display correctly? Can't really see the blue over the red...

Ah OK... I think I switched it out for Solarman Pro (also free) because I couldn't see my battery on smart for some reason... I'm keen to hear other's optinions on the different apps.
Here's a thread from power forum:

Different Sunsynk Solarman apps, pro's and con's

just wanted you guys opinions as to the accuracy of the various apps

How did you register your pro app?

I'm stuck here...

Based on your guys settings for Sunsynk, what should I enter on these screens?

Question on PV panel roof mounting kit for IBR Clip Lock roof. Which one's can I use ? Cost ?

My installer has quoted R8500 to mount 16 panels (455w Canadian Super High Power Mono)

It depends... i know i know.. but it really does. Where the installers able to put the CT coil in the main DB? If so then Zero export to CT will power the house incl Geyser in your setup, Else leave it on Zero export to Load.

In terms of the time of use - you have 2x4.8 kWh batteries - depending on your baseload you might be able to make it from 6pm to 6am on those (with no heavy loads like geysers of course). In that case setting your SOC to something lowers like 30 or even 20% would work well - PV powers your house during the day then batteries at night

Use the system for a few days and decide how you want it to work for you then experiment with different settings

I have grid checked and battery at 80% cos I need to be able to keep the battery fairly topped up if we're hit with extended outages. Checking the grid box means Eskom will charge the battery if it goes below the % value. Zero export is a must so that it doesn't send power out on the Eskom line but you need the CT installed on your incoming live line before it hits your DB or in the DB... that then connects to two pins on the inverter to signal current demand from Eskom and 1) prevents reverse flow out to Eskom and 2) let's the inverter know when non essential appliances are demanding power from the grid and allows the inverter to supply that need from solar if there is excess... one of my fav features.

My CT came with 4M of cable, I had to use Cat6a twisted pair to extend it to the board. It's working well over 14M now... just use a twisted pair.

Yeah the CT is installed but I'll have to look at doing this myself. Was told that my inverter is more than 20m from the DB so PV can't supply excess to non-essentials.

It may just be more effort than it's worth since I'll probably double my battery capacity in the next year anyway and just move everything to essential...

Base load seems to be around 700w which equates to ~7.3% battery discharge per hour. Set my battery to switch over to AC at 50% for a start. This should give me about 7 hours in the evenings before I have to use Eskom.

For a 2 hour load shedding stint that's about 15% which takes my SOC to 35%, assuming I already hit the 50% (at which point I should be asleep anyway). Can handle another 2 hours before it hits 20% at which point it cuts off...
 
Get them to connect the CT even if it is over 20m. I was also told that it won't work and it worked just fine. My geyser works perfectly fine from the sun between 12:00 and 13:00 during the day.

As said before, extend the wires using a single twisted pair on a CAT6 cable. (Don't connect a twisted pair to each wire on the CT)

Great install you have there.

Steve sent me the wrong Klip Lock brackets when i ordered my system. You can see in the picture. It is for the thin seam klip lock roof. Its called a Renusol Seam Clamp E-Mini.

He then sent me the right ones. Its called Runosol Seam Clamp KL+ like below. Non invasive brackets so no holes drilled in the roof.

I paid around R2800 for the 44 brackets. And then i also had to get the aluminum rails that mount to the brackets.
That was the VarioSole+ Mounting rail 41 x 35 x 4400 mm, 8 x 4.4m pieces and the cost was about R2700

@Mike Hoxbig How have the last couple of days been? How is the system performing for you

Been going great so far. I only had yesterday as a full day of logging though and already identified some improvements.

Have it set to switch over to AC at 50% SOC. Batteries are charged by around 10:30. Today being overcast it was still charged by 11:00.

The nanny was ironing the kid's clothes from about 13:00 - 15:00 and the PV matched the load. Pool pump was set to run from 15:30 - 18:30 and again from 01:00 - 03:00. This is why my SOC hit 50% shortly before midnight, otherwise it could have gone well into the early hours. I've now changed it to run from 12:00 - 16:00 once a day.

I'm not pushing mega numbers for production because I'm not exporting to grid, so my PV is basically just matching my load which is quite low. Moving the pool pump to run during the day should push my production up.

Need to find other ways of wasting power during the day - I know I need to sort out the CT coil issue so my geyser can use excess PV, so that should help push it up as well.

But for a 6.3 kWp system I think it's holding up well. On Tuesday before I started logging I saw production hit 5.4 kW on the inverter when I put the kettle, microwave, dishwasher and washing machine on to test while the pool was running...
 
Bring your pool pump to an earlier day slot as to not eat into eskom and battery.
