My Growatt inverter seems to be underperforming when it comes to charging my lithium battery, as it's only providing a maximum of 2.7 kW from the grid. However, I noticed that by adjusting the inverter settings and switching the battery type to lead acid, the inverter is able to charge the battery at a higher rate, reaching up to 3.8 kW. I've already verified that the charging current setting is at 100%, yet the issue persists when using a lithium battery. Has anyone else encountered a similar problem and can offer assistance in resolving it? Your help would be greatly appreciated. Thank you!
