What do the battery setup screens look like?

The charge/discharge here shows 70/40 respectively but the battery was charging on 37A. This is also the spec for the pylontech. The settings on the inverter are overridden by the battery BMS. I changed the  charge/discharge on inverter to 37/37A as per battery spec.  Have the dongle now so will also check the firmware versions. Does the battery also have firmware?

Saw your post now on the sunsynk forum. 

Try swapping the batteries around and see if that work. Make the current slave the master. It could be that the BMS is faulty.

have only one battery.

The alarm light seems to be on. What alarms is it throwing. 

That was when we first powered up everything and the battery was 41% SOC and 10 minutes later loadshedding hit🥵. and later when the battery was below 30% the photo was taken. Here is a shot from today 230pm.

Will try the Activate and Grid signal tomorrow and see what happens.

Would have tried now but the system is at a friends home.

Latest version Is e410 and MCU 2137 I think. 

Have COMM:e405 and MCU:2130. Purchased the wifi dongle today and will see how that goes. Any tips will be appreciated.

Did see on the Sunsynk website the ffg. warning: Quote

"Before doing any upgrade on the Sunsynk UI please check that the inverter is newer than:- 1904 xxxx

If older than this model number then the only upgrade that can be done is

E410 Otherwise you will damage the inverter.

Please take care to check the ID number of the inverter before attempting any new upgrade."

Is the 1904 xxxx the ID number?  Mine starts with 2004

I also have grid signal and activate battery enabled on mine. 

Set the Grid Signal ON and the Activata ON  and Voila! it went up to 100%.

Thanks to ALL who contributed for all the advice and tips.

Will hold back with the Software updates for a while to monitor the system.

Mucho appreciated.

Bro In Law has acquired a Sunsynk 8kw and 2* 3,5kw pylontechs. Has a SMA SunnyBoy 3.6kw and 3kw panels currently. Wants me to rig the system up. So above was a good learning curve.

Have 2 options 1. Flog the SunnyBoy and use only the Sunsynk with a backup generator for eventual Offgrid. And add a 3rd pylontech down the road.

Or

2. Parallel the Sunnyboy with the Sunsynk for now to overcome loadshedding and do option 1 down the road.

Looking forward to doing this.

I think you can ac couple the sunnyboy on the aux input of the SunSynk inverter for additional capacity.

As @Achmatsaid, you could use the AC coupling but don’t see the benefit of not using the built in mppt unless you are also adding panels with the new set up as well. 

Yes that's a plan but will have to look at the specifics closer since the roof real estate allows for only two more panels and if we AC couple will waste the MPPTs on the Sunsynk.  Currently 11 panels 6 & 5 panels per string into SunnyBoy on N facing unhaded roof and not visible to public. Will need to convince Bro in law to use the other roof spaces for more panels. He is not so keen wrt. aesthetics.

Will try and convince him otherwise. Will keep the group updated.
