Hi. 

I have a growatt spf3000tl hvm 24 inverter with 2x 100ah gel batteries. No solar. Basically want to use it as a backup during loadshedding etc so using eskom as the charging. 

Problem im having is that it stays on charging, the chr light keeps flashing and the fans run fast. Sometimes it the light will go solid and the fans slow down, but after few seconds it will start again. 

Is it perhaps a setting issue?

sounds like you have the lithium setting on use2 ? correct for battery under setting 05 what setting have you selected 

I have selected the user defined option. And then left the settings of the charge and floating voltage on default under option 5 where you can set the user defined?
