Probably a really stupid question to ask. I did wonder if it would be possible to set it as a lead acid battery as this doesn't look for a bms and then edit the charge/discharge parameters to suit my battery? Just a thought as the bms itself will monitor the battery cells and shut off the battery if something was to go wrong. Would need to figure out the best settings before changing anything.

Hi Martyn Thanks for taking your time to reply, to be honest I know nothing about data coms and don't really have a clue where to start with this. My BMS has four terminals marked VDD, TXD, RXD and GND, at the moment I can connect a Bluetooth module for a phone app that uses all four terminals or a PC module that only uses the TXD, RXD and GND terminals. I have got one of these RS485 to RS232 converters https://www.amazon.co.uk/gp/product/B01LVVI1XI/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 I've also ordered these https://www.amazon.co.uk/gp/product/B00006IRQA/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 https://www.amazon.co.uk/gp/product/B071DS5GTW/ref=ox_sc_act_title_1?smid=A2PALI197JW80Z&psc=1. I've emailed Sofar several times asking for the protocols, but I never get a response from them. At the moment because I don't have a BMS connected to the inverter it's in fault mode and doing nothing but displaying grid, solar and consumption kW, but even that doesn't make any sense. it's like the grid and consumption figures are reversed. Not sure if this may be due to it not communicating with the battery yet. Basically all I have is a glorified inaccurate data logger.

Hi guys Thanks for an informative forum. Can anyone help. Also please excuse my ignorance as I have no clue about data coms what so ever. Problem I have is a Sofar ME3000SP Connected to a generic lithium DIY powerwall battery. The Sofar has a RS485 coms port and my battery BMS has a RS232 coms port. I think I have managed to find the BMS protocols for my battery BMS but I can’t find the ME3000SP protocol. Was wondering if one of you clever fellows may have it. I’m hoping that if I can get the two protocols there may be some way of getting them talking to each other, maybe with a raspberry pi or something. Thanks Chuck

Hi guys,I Please excuse my ignorance with thius, I have no clue at all about data transfer and coms. I'm having trouble with he ME3000SP coms. I have a generic lithium battery that has a Chinese BMS with a RS232 coms connection. I think I have the protocol used by the battery BMS. I'm trying to find the coms protocol used by the ME3000SP, sounds like you guys may have the information needed for me to try a mash something together to get it talking to my battery. Any help greatly appreciated Thanks Chuck.
