Thanks for your replay, that answers my question.

Thanks for the response. Should the two values be different values on the Growatt or should they both be set to the same value, in this case 30A as mention. Will it have an impact on the charging rate of your solar if the "Charge source priority" is set to Solar and Utility. I see the "Maximum charging current" states that it should be set for "Max. charging current = utility charging current + solar charging current" and the "Maximum utility charging current" states that if the Maximum charging current is smaller as the Maximum Utility charging current, it will use the Maximum charging current setting.

I wonder if anyone can help me. I have a GROWATT SPF-5000-ES Inverter with 6 x 330w panels and 4 x 200A gel batteries (48v) . Wat will the recommended "max charging current" and "Max utility charging current" settings be for the installation. Thanks Matt
