hello, my GW5048D-ES inverter tends to give a slow response time when drawing from the batteries, when there are loads connected it starts drawing from the grid and slowly, slowly, it starts drawing from the batteries if there is no sun. my complaint is that it is not very quick to withdraw from the batteries, so the customer consumes from the network more often

Yes, that's only a problem if you limit export. It has to err on the side of caution so that people with meters that go into tamper mode when it accidentally exports don't have to deal with that issue.

sorry I don't understand what you mean. unfortunately the translator does not translate well. Could you express the concept in another way?

If you enable export, it is fast.

If export limitation is enabled, it has to do it slowly so it won't make a mistake.

Se abiliti l'esportazione, è veloce.

Se la limitazione dell'esportazione è abilitata, deve farlo lentamente in modo da non commettere errori.

thanks, I'll wait for them to connect the counter for the exchange

Your question is not very clear. Where are you from ?
I assume you mean that when the Essential or Non-Essential Loads suddenly increase, there is a certain "Inertia" so that the Power coming from the PV or the Batteries (if they are available in sufficient quantity), can cover the instantaneous demand, until that moment. moment (just a few seconds) the Energy required by the loads is taken from the GRID.
However, this completely changes in the event of a GRID power outage, as the inverter's Working Mode change is almost instantaneous (just a few milliseconds).
This is normal Goodwe behavior. However, the power consumption of the GRID is minimal. It's only a few seconds.

I'm from Italy, I apologize for the type of English but I use Google Translate. You understood perfectly what I wanted to say. Another information: I saw on the "installation booklet" that if I set as Country Australia the inverter should give in discharge from the batteries 5000 kw. Is this possible?

The inverter must configure it with your exact country code. I don't know about AC Power from Italy.
The Goodwe Maximum Nominal Power Value is 4800 Watts (over 240 Volts), but since the voltage of the Countries is different, this varies slightly. It is better that you evaluate according to the Maximum Amperage that can be fed from the Back Up (essential) loads. this value is fixed:  20 Amp. Therefore, if a country has a Voltage of 230 Volts, the nominal maximum power will be 4600 Watts.

thanks for the information.  one more thing , look at the photo.  despite having charged batteries I take from the national electricity grid, why?

grazie per l'informazione. un'altra cosa, guarda la foto. pur avendo batterie cariche prendo dalla rete elettrica nazionale, perché?

I understood by myself. more than 4800 kW I can not take !

but do you think I could put another less powerful inverter and connect it in parallel to the one I already have in order to support more load?

good evening everyone, I noticed that through the Pv Master app in the messages section I find some repeated errors. I leave an image for you to understand

buonasera a tutti, ho notato che tramite l'app Pv Master nella sezione messaggi riscontro alcuni errori ripetuti. Lascio un'immagine per farvi capire

I have a proposal to make: why don't we write what firmware version we have? in order to compare and understand which is better. we specify from which app we read it . there are differences from app and app seem portal brings one, Pv master brings another.

Seem portal : 6232617

Pv master : 1717A

A couple of grid lost errors, and a couple of DC injection high - request firmware 2222E - it seems to handle the DC injection error better in some cases.
