HyperCut

Great looking install. Mine is similar spec only with 18x 545w Canadian Solar panels.
Very happy with the results so far. Been running for just over a month.

Pv Production for the day +/- 33kWh
I have a Dewhot 16 CT Gas geyser installed for the bathrooms. The CT (Constant temperature) range geysers adjust the flame to output a set temp on the digital display. So if warmer water enters the geyser the flame adjust accordingly and uses less gas.
The Electric geyser will be installed with a solar valve.
The solar valve diverts water to the gas geyser if the temperature drops below 45 Deg and bypass the gas geyser if above 45 Deg. You can adjust the temp setting by 5 deg.
Electric geyser will be set on 65 Deg,
Hopefully on nice sunny days no gas will be used.
 

So my system been running for a few months now and the amount of power we have available is just beyond my expectations.
Decided to add another Hubble for a total capacity of 15 kWh with an average of 35% SOC in the morning.
Prepaid meter been standing still for 2 months even with all the cloudy / rainy days we managed to not use the grid.
SHOULD HAVE GONE TO SOLAR YEARS AGO !!! 

Yes a very good friend of mine that i am currently working with.

You can set the aux to only run when batteries are above a certain SOC if the grid is down. 
If the grid is available it will use from the grid first before doing into batteries. 
 
Grid down scenario 
Daytime pv goes to load, aux and batteries 
Nighttime batteries powers load then optionally can send power to aux. Its batteries drop below a certain thrusting then only loads will get power. 
 
Grid available 
Daytime pv goes to loads, aux and batteries. If allowed, excess can feed back to the grid side. Overcast will be the same as nighttime below. 
Nighttime batteries powers loads then aux until set SOC is reached. This can be 100% then batteries will never be used for aux loads. Aux loads will then get power from the grid.

System:
16X Canadian Solar 540w Panels
1x SunSynk 8Kw
2x Hubble Am-2's
1x Keto 1 with 200A fuses
1x N/E Bonding DB
70mm2 Batt Cables (Still need a decent Busbar) looking @ DIY
 
Items was ordered and most has arrived, waiting for the battery's and Keto 1 Disconnect.
Installed the Trunking and DB's yesterday. Will start wiring over the weekend as the panel brackets will only be back from Galvanizers in January.
 
 

Very neat install, Yup 16mm2 are a challenge but somebody has to do it  ☝🏼

Entered Commissioning and Testing Phase - #Respect for those who work with 16mm cable on a daily basis.

I agree SunSynk’s way better than some of the other more expensive “blue” units 😉

EDIT-  issue resolved. The one inverter didn’t save the Modbus SN number.  Changed the Modbus SN number and enabled the parallel and saved, inverters immediately did a reboot and once they came online immediately started charging the batteries 

No... The older model will only accept the 1.46 version and the newer model will accept the 2.05. If you are installing the 2.05 on a battery and it says bin file error then install 1.46 on it and it will update. 

Need to buy a USB to RS234 cable R500 
 
Then phone Hubble a d they will email your the software 

Yup same here after the upgrade, lovely to have them working as they should !!

REPORT BACK:
All good since the firmware update P1247V110-12290V205T-0316.bin on Fri 16th May Fri 13th May.
Glad to say that as of today Mon 27th Jun 2021, all is still good with Hubble AM-2.

After the firmware update I reverted the SunSynk from AGM/V to Lithium (CANBus)
>capacity, floating, equalization, shutdown, restart,
These are all manually input - I used the same SoC values as before.
Shutdown, Low Batt, Restart, Work Mode change from V to Percent SoC when using Lithium battery type.
The inverter stores both values, so when switching, only need to enter your values once.

Please note that it took a 24h cycle to re-calibrate the SoC - see attached graphs.


 

 
 

Plug USB cable into Win 10 Laptop
Wait about 5 minutes for Windows to install the FTDI driver from the internet (make sure you internet connected)
Check Windows Device Manager (devmgmt.msc) to confirm the COM port. Connect RJ10 end to AM-2 RS232/Console port (see below) Launched "BMS Upgrade V1.0.3.exe" - choose COMx/9600 corresponding to the Device Manager COM port Browsed for the firmware file P1247V110-12290V205T-0316.bin Entered the password Press UPGRADE button Upgrade takes about 90s Battery did a small beep The SoC will reset and may have an incorrect SoC.
I ran a discharge(20%)/charge(100%) cycle and the SoC adjusted to correct value

Update: 1 June 2022
It's been 2 weeks 3 days since I updated the firmware on the 4xAM-2.
So far all good.
SoH 100%🙂 and Capacity 105Ah😢 per battery.

The firmware installation was done with with a Windows 10 laptop and USB/RS232/RJ10 console cable

EDIT: had to do a discharge to 20% and charge to 100% for reported SoC to match actual SoC.

Sunsynk 8kw with 2 x BSL 5.1kwh. 
Panels will be added next month.

The new dongle now comes with the Sunsynk inverters. I think it is worth it. 

Bought from a Electroware in Vereeniging.
