W@P's Solar System

Any idea why my PV would drop like in the graph below and grid kick in?

Looks like batteries were full so PV supplied load (about 1kw between 930 and 1) then load picked up again; perhaps some clouds caused PV to drop from 1:30 to 15:15 Grid came in to supplement. Seems system is setup to keep batteries at 100% hence they didn't supplement

What does your System Mode screen look like in terms of battery settings?

Mine does this on occasion as well even though all my battery settings are set to 2% - only if grid is connected.

mmm, bizarre - might be a firmware issue on the Sunsynk then
 
I set the time slot between 13:00 - 17:00 to keep the battery at 100%. That's when my geysers run. I thought rather let them draw from the grid if there is not enough PV. I guess it's much of a muchness?

My 2c change your geysers to run from 10 to 12 they can "topup" for 30 min then at 3. No need to keep that at 100% either drop it to 20% only touch these settings when loadshedding kicks in again

Will have a look thanks
 
So I got a reply from Hubble regarding how to connect the cloudlink to the battery and inverter. In short, they said that no ethernet cable supports full monitoring ATM. They have another cable they can send me that connects to the RS232 port of the inverter and the S port on the cloudlink. That means that I have to remove my Sunsynk logger. WTF?

Feels like I have a red piece of 3d printed paperweight that I paid a lot for.

Once you have been monitoring the system 2 months plus I dont know if the new sunsynk dongle is even worth getting now.

I can change my setting remotely using solarman business.

Do I care that the info is delayed 10 minutes? Well im used to it now if I need on the fly info I just look at the inverter which is very rare.
 
Very nice system and install you got there!!!

What I have found was that sometimes the users do not really understand how these systems works.
To make your system work 100% for you, connect your geyser and oven on the eskom side of the system. Make sure you also have the CT coil installed at your main home power meter.
This way you will still use PV power for these loads, but it will not drain your batteries during loadshedding.
Set your batteries to drain to say 40% with eskom power available, this way you still have that extra 40% available during load shedding.

Rather increase your battery capacity.Since I went from 12kwh to 24kwh my system has been performing extremely well.
While using the stove and AC during the night, I am still only using battery power.
During the day I can then utilize full PV production all day.
 
This rainy weather resulted in my geysers being topped up with eskom power yesterday.

Dont know what happened here. I know the geysers kicked in but it looks like all the fridges and freezers did as well. Not sure. Its the most PV production I've seen since the system is installed. Happy either way.

SO i received the special cable from hubble and connected it to the RS232 port on the Sunsynk and S port on the cloudlink. This is what I can see.
