@wolfandyIs there a link for ICC to purchase the cables.Sorry do not know what ICC stands for.

Hi Anonymous_Llopi Thanks for the detailed explanation. Will now proceed to do the updates, Mucho appreciated

Hi All, Have the same situation with the alarm light on 2*US3000B and new 2*US3000C. With a Sunsynk 8KW inverter Have a few questions before attempting the updates. When updating the Pylontech US3000B/C, is it OK to just update with the last version of software as provided above? Is the console port cable and a usb-serial converter ready to use or needs modifying? Can one purchase the cable/converter online? Will highly appreciate all feedback.

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.

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.

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.

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

Will try the Activate and Grid signal tomorrow and see what happens. Would have tried now but the system is at a friends home.

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.

have only one battery.

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?

Well it was on 88% all night and up to around 3pm this afternoon. The system is initially setup as a backup ups mode. Thought the same as you but still waiting for the jump to 100%.

This morning the battery is still on 88% and 5 lights on the battery green. Seems to be stuck on 88%. Will look at FW versions today and get the wifi dongle.

No wifi dongle yet. Did the installation for a friend. So will probably check the version tomorrow.

Need to check the versions. What would the newest version be. Is it easy to update? Whats the procedure for the FirmWare update? Appreciate the support from u all here thanks.

Need to check the versions. What would the newest version be. Is it easy to update? The use timer is not checked, presuming it will not follow the time of use schedule and would at all times charge battery from grid if need be. The system is just battery backup for now, with solar and a 2nd bat down the line.

It started charging after the comms was changed. That was at around 14:17pm and it was on 49%. At around 17:18 it was 88% and 17:57 it was still 88% and at 6pm was load shedding. So will get a reading at 8pm. Will take a reading in the morning when it should be 100%. The plan is now to install PV panels in a week or two. A second battery may be on the cards. The Inverter is a Sunsynk 5.5kw.

Hi guys, Changed the comm cable this morning to the CAN ports and the inverter is now showing the Battery stats. dip switch are all on 0(down). Battery charges at 37A (Pylon recommended charge rate) which is not the setting on the inverter (70A). Does the inverter Or the Li BMS control the charging? The battery now seems to be stuck on 88% SOC (on inverter UI) and 5 leds on battery SOC for the last 2 hours. No clue why that is. Any ideas guys. Thanks again for all the tips.

Thanks Vassen. Also on the single battery dip switch settings i have 1 0 0 0. set . Is this correct?

Cool will try it tomorrow! Thanks for the response.

Hi Achmat, Thanks for that. Did u use the same cable but in the CAN port? Or is a CAN cable different?

Hi Guys, Just did an install for a friend with a Sunsynk 5kW for UPS only with 1 Pylontech US3000. Used the RJ485 cable provided with the battery for communication. If I go by the info on UI -> Li-BMS icon and section 4.13 of the install manual, the screen shows all 0 values. I take it that the communication is faulty. Did u guys use a CAN cable for the Inverter-Battery communication? If so is it a generic CAN cable? Will need to get one to sort out the comms.

Thanks

Hi Guys, Does someone have the specs for the SOL-I-AX-5P. Need to plan the PV panels first and see what is accepted into the inverters Solar Charger, that is Voc and MPPT range and max power PV panels allowed.
