How do I force detection of a Lithium battery?
My 8kW Deye won't recognise the BYD Lithium battery set / BMU. This means the data isn't auto-inserted into the Deye charge profile. But worse - the BYD sees the situation as 'no-comms' so switches itself off after ~5minutes, triggering an alert on the Deye and shutting the whole system down. To start with, I've checked cabling, port use etc, and after a few hours of nothing working I have come here for suggestions / advice. I've tried everything I can think of, including 3 x different patch cables between Deye and BYD BMU. I also reset to factory twice, on the Deye. The confusing thing is - I have an identical set of equipment at another site on my property that worked perfectly first time and still is. Any assistance would be greatly appreciated. Can it be forced to detect, or the instruction for BYD comms programmed over the air? Cheers!
Hey Groots, and anyone else interested. I have 'solved' the problem by buying another set of BYD batteries. The original ones are the older 2.54kWh units. The new ones are the 5kWh Flex. The flex is known to be compatible, and once I connected it all together they talked - after 15minutes or so. Anyway - all working now. Cheers!
