5kW F03 and F13
Hi all,
Recently installed Sunsynk (5 weeks running OK and impressed with the machine). It threw out the following codes this morning - have checked forums and manuals - wondering if anyone has seen them before. I suspect bad grid power has something to do it:.
Sunsynk 5Kw
2 x Pylontech US3000C
10 x JA 455s
(Used in area with Prepaid meter)
Hoping someone can help with:
1. Anyone seen any of the codes before? Particularly F03. Also why F13 is continuously coming up every 2/3mins before the DC Low came up. It might be linked to this - but what would prevent the inverter from switching to grid when the batteries reach the specified time of use SOC - e.g. 35% below? Bad grid being filtered by the inverter settings?
2. CT coil - have watched the videos - I have the old software. The software has a “HM” signal to show wattage and this is reflecting a negative wattage - which I take to mean they installed it the wrong way? I know it clearly says CT on the new software - just confirming my assumption that this used to be “HM” on the old screens? I’m set to Zero export>Load only so hopefully no impact. Will correct the CT coil and switch to HM load too.
3. When exporting once battery is full to non essentials - this is ONLY excess solar right? I.e. non essentials will not use battery.
4. My time of use functions are included below. I’ll tweak them a bit for loadshedding - however: question: >what would happen if I changed the 35% to say - 50% in all lines that have 35%
>then grid went off/loadshedding
>would the time of use settings mean that I couldn’t use my power if my batteries were down to 50%? Or does time of use get overridden when grid is shut down? - I.e. allowing me to use the capacity from 50% down to cut off prescribed in battery settings.
Thanks - apologies if these have been asked elsewhere [also put the questions on Power Forum]
Cheers and thanks in advance.
Thanks @Vassen Moodley - I will double check it again tomorrow but it seems that it is charging at 7am from the solar and not the grid. The reason I've put grid charge on is during that time is that there is currently bad weather/cloudy days - coupled with loadshedding so end up being stuck at the end of the day with no grid/battery due to the bad weather so trying to maximise the opps of getting full batteries by 5pm - whether through grid or solar (e.g. if I use the batteries down to 35% overnight and its an overcast morning and I'm hit with loadshedding - my inverter will cut off as I'm leaving little leeway - obviously possible still under the current settings but in the event the grid is available early morning then I'll use it). I'll uncheck the grid during those early hours in a month's time when the cloud cover subsides a bit and the worst of winter is over.
Re upgrade - noted - however, I don't have a data logger yet - figured I'd wait for the new one to come out. Waiting for @Joel Egan to hook me up! (I joke)/ - waiting until the new ones come available.
