Hi , I have a Growatt Inverter and I have some questions I hope you can help me with about the info in the display panel .

Today I checked my inverter in about an hour before sunset , and then I looked at the display and I saw this at the first time :

 

Again half-Hour before sunset :

 

after 5mins from the previous image:

 

Please I need to know what the diagrams on the screen really mean ? specially in the last two cases of battery using .

And another thing , The Sun is still up and I have no idea why would it use the batteries in last half hour before sunset?

Note: The CHG indicator is not blinking in all of the cases ,  I think this means that the batteries are Fully Charged and the AC/IN indicator is blinking Because Grid is Off . 

 

Regards 

@TheJackal welcome and congrats on that beauty.

On all pictures you are on the amperage screen opposed to the wattage screen and voltage screen. .

Because you are on solar first(sbu/solar-battery-utility) the panels are powering the load  and charging the battery on first picture.

On the second picture the sun is setting so your panels are producing less as you see the arrow pointing up from the battery but you are producing just enough not to use the battery.

On the 3rd picture the panels are not producing enough so the inverter taking what it needs to power your load from the batteries. 

If you are using lithium batteries you should use battery first(sbu) to use the battery after the sunsets.

Both solar first and battery first are sbu which means that first to power the load with be solar if not enough the battery will power the load at the same time.

 

@Buyeye , Thanks a lot for the reply
