Hi all, I think I found the problem. The issue was coming and going randomly, knocking on the inverter side was helping, but only for short period of time. I open the inverter and when I touch/move slightly the highlighted PCB the inverter was switching on and start powering the load. This...

Hi boys and girls, I have very strange voltage and load issue with one of the two parallel single phase Growatt SPF 5000 inverters. This morning I noticed that Inverter 1(called Postroika in the graphs ) is always supplying alone the whole house, while the second inverter (called Pokriv) is...

I think the only issue is commercial one - i.e. force you to buy new products. The physical layer is the same, just the IDs content may be is different or just added some new IDs that the invertor will look for and BMS will broadcast. I am sure if they want they can put any CAN 2.0 support in...

Hi DLMB, from what I know about the ARK 2.5L CAN is that in one of the IDs is responsible for the battery type and its software. It is totally possible the 5000ES Firmware to check the battery type and reject it if it is not acceptable...or what I know about 5000ES is that it send a constant...

Hi there, ARK 2.5L-A1 is only CAN protocol capable - so RS485 wont work on it and there is no such a think like a CAN HUB. There is a can gateway, but hub is not required for CAN cause all devices are connected in parallel to the CAN bus. Check you settings for protocol setup in the inverter...

Hi @hugoboss00 My id=320:47,54,03,04,00,00,00,00 - it is static and I think is the type of the battery, BMS software...etc, so I just re-transfer this id message from the battery to the inverter, no worries cause the limits are stated in another id=311. For a week I am testing some code, last...

Good morning ( at least on my side of the globe). So I have successfully managed to "alter" the protocol between the Growatt ARK2.5L and the inverter and use DIY battery with the Growatt one - more details bellow - this will be big one. 1. I sourced locally 16s 280AHs LiFePo4 cells. I bought...

Thanks for the quick replay Sidmouthsteve. Anyway ordering, by myself, only few batteries from China wont be economically fusible due to the cost of transport, custom charges and VAT - but I send a request for quote for the one supplier that I found offering ARK2.5L. The SunArk is offered in...

Hi guys, I am new here, but I used a lot of topics to build up my home solar array.... So on the question - 1. do you know if this battery (Growatt Ark2.5L) is with discontinued production ? I live in east Europe (Bulgaria) and I bought only one when I was building my solar - just to put my...
