Found this, because I've the same F56 every day after charging 4x US5000 Pylontech. Inverter Deye 10kW cuts off power and searching for answers has been started. I cannot change battery settings to Lithium, so it stays in Use Batt V but MAYBE with the wrong parameters. I'm off grid now for eight days and every day troubles. Greetings, Ad from Curaçao.
