Growatt SPF 5000 ES

[Mino]

Good evening everyone, I thank you all for giving life to this portal for photovoltaic installers.
I am a new user, and please excuse me, I am using an online translator, I am not an expert in the English language.
my question is this, I have a SFP500 ES inverter from Growatt, I connected everything (panels-batteries-line-protection switches and inverter).
Once everything is turned on, the solar panels give me 112V (3 panels in series)
but by scrolling with the keys I have no information on the current or power of the panels..and furthermore I cannot charge the batteries....
Do you have any advice on how to solve my problem.
I thank everyone in advance.

SPF5000 ES requires a MINIMUM Vmp of 120V for the MPPT to work. You need to add at least one more panel in series; 5 in series would be better.

Thank you 1000 sunshine_eggo
Thank you for the information you gave me, everything is clear now. I have 3 other panels to connect, so with 6 panels I should see that everything works well.
I have another question to ask you, I have 400W panels if I connect 6 400W panels and 3 500/600W panels in series always in series...can I have problems?
Thanks again for your technical information.
Thank you

Thank you

When you connect panels in series, the string will always operate at the current of the lowest rated panel, so if the panels are about the same voltage, the 500/600W panels will only perform similar to the 400W panels.

But wouldn't the inverter show on the display the voltage even though it doesn't work at a voltage below 120v?

OP indicated the display of voltage (112V), but not current or power.

Ah, I stand corrected.
