[QUOTE="binky, post: 519158, member: 490"] as far as I'm aware, system limiting is by making the MPPTs less efficient, but it sounds like your inverter targets one string to achieve this. I guess each manufacturer will have different means of controling power. The inverter is designed to protect the battery either way, so I wouldn't worry too much about that. Not sure about battery 'learning', they tend to work to preset programming, but the inverter and BMS do talk to each other. To be frank, it sounds like it's working properly, especially if it is topping up the battery from the grid occasionally. You will see grid voltage rise, the inverter will be loking at the grid, then exporting a higher voltage, so that like water at a higher level, energy from a higher source, ie your panels gets used in the house first. I've seen inverters put out 260V before and I think many are set to max at 263V. [/QUOTE]
