Okay i get you. i had to contact my battery manufacture and they gave me settings to use on the inverter since there is no communication between the inverter and the battery and so far seems to be working. Here is the link: https://m.alibaba.com/product/1600646977619/hybrid-inverters-2022-new-10.2KW-solar.html?__sceneInfo={"cacheTime"%3A"1800000"%2C"type"%3A"appDetailShare"}&from=Android

@Talino8 Do you have communication between your battery and the inverter?. I cannot afford to damage the inverter again hence i'm asking for advices from people that have done it already and working accordingly or properly

@Talino8I bought it from Curley Wei Via Alibaba. unfortunately i dont have Panels yet, only planning to add them soon.

@Talino8Thank You. Does this mean this inverter works only on open loop communication with the battery since there is only one port (COMM)?. Luckily the warranty covered everything, the seller is going to send me new card and i'm advised to use RS232 on the battery instead of CAN port

I contacted the Manufacture and they said i must use RS232 port from the inverter to the battery. I then contacted the battery supplier and they said communication on their battery can only be established via CAN port and not RS232. so i'm a bit confused now while waiting for the new RS232 USB converter for the inverter

Hello Valyh. I'm not sure what software version is running on this inverter. i contacted the manufacture and they also told me that i must use RS232 but now the battery manufacture says you can only communicate with the battery via CAN port, so i'm confused now. I must now buy a communication cable (RJ45 to RJ23) not even sure such cable exist. I will be afraid to try this since you saying you also burned the USB converter while using RS232 port. My battery has 4 ports available( CAN, RS232 and Two RS485).

I bought victor max inverter (10.2kw) in december. I got someone to do installation for me, after installation he connected communication cable from inverter comm port to battery CAN Bus port. inverter worked for about 20 minutes and smoke came out of the inverter and the inverter switched off. Opened the inverter and found the card with comm port burned. i contacted the seller and new card was send to me, i connected the new card but inverter still failed to switch ON. The seller then send me a new motherboard, i replaced the motherboard and the inverter switch ON and worked well without without communication with the battery (Open loop communication). I wanted to do a closed loop communication between the battery and the inverter, contacted the seller for assistance but received none. Tried to establish communication and card with COMM port burned once again. I have to get a new card but i need assistance, Anyone who knows how to establish communication between victor max IP21 and lithium battery (51.2V)
