Yes I am planning to add more panels, but what is the idea behind program 14 sol+utility if it wont charge the batteries from solar and utility at the same time??

this is the exact options I have set as seen in the image, but the issue is it is not charging unless either solar is very high or solar is completely off.

but what is the use of SOL+Utility to charge the batteries if the utility wont charge the battery in case solar is not enough to support the house?

I agree that if I reduce the load it will charge the batteries, but shouldn't it charge sol+utility by drawing the needed current to charge the batteries from utility?

Here is another image where utility is supporting the load together with solar but no charging is occuring for the batteries although program 14 is set to sol+utility.

The issue is the inverter is alternating from charging the batteries to drawing current from batteries for no reason. Notice in my image the arrow from battery to inverter although I have utility and solar providing me with current. This happens specially when solar energy is not enough to power the charging and the load, expecting utility to support but that does not happen. Instead inverter starts drawing current from batteries. I am having to turn off the dc breaker to disconnect the panels to force the utility to charge the batteries in the late afternoon since it takes long until solar energy to completely dissapear. Note that even at night when there is no solar at all, it alternates from charging to drawing for no reason.

Here is an image, although it is getting dark now but this shows my point where battery is providing energy instead of charging. AC grid does not charge the battery until no solar energy is detected at all. and btw even if I put the charging on SOL+Utility the same happens, which is utility never charges the battery until Solar is completely off.

yes i have set it to CSO exactly, but the issue is it goes to battery mode when solar energy is insufficient until it is dark enough that solar energy dissappears and grid AC kicks in. While grid AC is not supporting the load with solar energy during daylight, instead battery is supporting.

Hello mates, I have installed a growatt spf 5000 es with 4 x 240ah tubular flooded batteries and 4 x 540w panels. I set up program 1 on "SUB" as I need to power my loads on solar energy with the support of grid AC. My issue is mainly when solar energy is insufficient, batteries start providing energy instead of grid. Grid remains providing a 0.4A current and does not support the load as it should since solar power is not efficient. I set up program 14 on "SOL" to give priority to solar charging and if not sufficient grid AC supports which is also not happening. The inverter keeps going in and out of charging mode. My firmware version is 40 05 701.
