Growatt 5000?

Hoeveel stroom verbruikt u per maand? Growatt
Hello Labeeman, In didnt know that it was a link to the device in meer. Sorry for that. Thank you. Ik couldnt find my invoices but i think it must be somewhere about 150 kW montly in winter and about 120 kW in Summer
 
You use only use 5kwh a day at 150kwh a month. It might pay you to look at what is the biggest power users you have you may be overpowered on the inverter.
 
U verbruikt slechts 5kwh per dag bij 150kwh per maand. Het kan u lonen om te kijken naar wat de grootste stroomverbruikers zijn die u heeft, mogelijk wordt u overweldigd door de omvormer.
thank you for that Labeeman. You mean that the Growatt is much more powerfull than what I need? If I understood that well: dont worry, once I have it working i will wath much more my personal cinema and other devices that I am not using so much now cause of the kWh price from the companies here.
 
The bigger the inverter the more power it will consume doing nothing and taking up more battery power when there is no sun. you need to see what you are consuming.

Thank you for that wise information Labeeman
 
Hello,
I have two Growatt 5000 inverters and 20 panels. My plan is to connect 10 panels to each inverter.
Please confirm or correct me if I am wrong ?

The inverters have Maximum PV Array Open Circuit Voltage: 450VDC and each panel has VOC 41.85V

When connecting panels in series voltages sum up and total max voltage going to each inverter should be 418.5V which I think should be ok. Is 10% margin good enough to stay on the safe side?


Panel specs:
Maximum power (Pmax) 380.00W
Maximum power voltage (Vmp) 34.50V
Maximum power current (Imp) 11.02A
Open circuit voltage (Voc) 41.85V
Short circuit current (Isc) 11.64A
Cell efficiency (%) 23.11
Module efficiency ) 20.37


Inverter specs:
Maximum PV Array Power: 6000W
MPPT Range @ Operating Voltage: 120VDC ~ 430VDC
Number of Independent MPP Trackers/
Strings Per MPP Tracker: 1/1
Maximum PV Array Open Circuit Voltage: 450VDC
Maximum Solar Charge Current : 100A
