marbella Posted February 12, 2022 Share Posted February 12, 2022 Dear Experts! I have a 48v Pylontec US3000C Clone running with a Must PV18-5048-VHM Inverter and 12 panels a 230W in sunny Spain! First it seems I need at least 2 of these batteries to not exceed the current limits. But do these pylontec communicate the SOC level or other important parameters with my Must Inverter or should I use an other battery or another 'Inverter? us3000c-installation-manual-v10-20cqsv0801-ger-inu.pdf Quote Link to comment Share on other sites More sharing options...

I assume you mean a PV1800. 9 hours ago, marbella said: I have a 48v Pylontec US3000C Clone running with a Must PV18-5048-VHM Inverter Wow, a clone battery with a clone inverter. You must be brave. It seems to me that the inverter is based on an Axpert MKS 5K-48 (non-64 V). These Axperts don't have an RS-485 port, or firmware to talk to BMSs, but Must have expanded their designs since the original copy, so you'd have to check their documentation (I believe that they actually have some, not just copies of Axpert manuals). My understanding is that you'll probably not be able to connect them, but you can use Solar Assistant or a similar monitoring device to talk to both.

marbella Posted February 17, 2022 Author Share Posted February 17, 2022 (edited) thank you very much, I hope there is a software / firmware update available for the MUST PV18-5048vhm if not it seems I have to get a new inverter , maybe AXPERT VM II 5048 ? I found a new manual for must 18-5048vhm but this forum silly enough only allows 1 MB attachments!

It allows larger attachments in the files section, which is a better place to save a manual. https://powerforum.co.za/files Quote Link to comment Share on other sites More sharing options...
