johans9 Posted September 18 Share Posted September 18 Hi all. Hope all is well. I am busy upgrading my system 2 x 5kw OG 5.48+ kodak inverters in parrallel 3x mecer 5kw batries connected to one inverter 1x kodak 5kw batery connected to other inverter 12x 555watt pannels What should the charging rate be set to ?

Normally one would do this when one has power draw exceeding the capacity of one inverter, then you have to be able to supply both inverters from the same source/batteries, else in your scenario, one inverter's single battery could shut down, since its run flat and so will that inverter shut down also and then the one with the 3 batteries, even though it may still have 60+% energy remaining in the batteries could likely trip, since your load is more than 5kW, which is not what it can manage...
