Hi All, I have been having issues with the supplied CT (SPH5000 inverter) being inaccurate, tried replacing but still off. Decided to go down the meter path & at the recommendation of Growatt, purchased a Eastron SDM120CT MV, they sent me the connection details which are pin1 & 5 for the RS485...

HI All, Trying to work out the Protocol required to get my batteries talking to my Growatt SPH5000 Inverter, I have found that the Pylontech US2000-3000 are compatible & am assuming it is CAN BUS that is the protocol (I have got the protocol doc). Does anyone have the Pinout for the RJ45 on the...

4th time arguing with Aliexpress, the shop shut the day after I bought the batteries, I contacted Aliexpress straight away, the tracking number they gave never worked till they finally sent me a link to HJYT shipping company & what a miracle, it worked, only took 6 days for the batts to go from...

Hi, I am also looking into how to pass my battery info to my Growatt SPH5000 Hybrid inverter. Have you guys had a look at the DIYBMS (https://github.com/stuartpittaway/diyBMS), currently configuring these to replace the DALY BMS currently installed on my 4 x 48V packs & want to build a...

Hi, Could you port it from this? https://github.com/juamiso/PYLON_EMU Looks promising, I am trying to do something similar, I have a Growatt SPH5000 with several large batteries (27kWh total). Hoping to read info from batts sum it & send via CANBUS to the inverter. Matt
