What could cause a string to fail?
The other day my B string failed while the other 3 are still running fine. There are 2 Sunnyboy inverters as well. There appears to be no obvious cabling issues. I tested the gateway, power cycled the inverters and the power modules. I have sent the string failure warning email from Tigo to my installer.

What''s better, 1 big string or 2 smaller strings?
I have 18 new solar panels that I can connect to the MPPT1-port of a Deye Sun-10K-SG04LP3 (my old 5.25 kWp array will go the the MPPT2-port). I have two possibilities: To connect all panels in one string to the MPPT1-port, or to divide them into two strings that run in parallel on the same port.
What happens when you mix panels on a string
If string Vmp matches perfectly, you will be optimal when strings are combined in parallel and controlled by a single MPPT. When there is a mismatch in string Vmp, when the strings are combined in parallel and controlled by a single MPPT, the low strings will be pulled up to higher than Vmp (so current will drop under Imp and power will drop under Pmp) and the

Mix portrait and landscape oriented panels in a single string
That gives me three strings with 18 solar panels in each string. Not so bad. Now, I have the option to fit three more panels in portrait orientation. That is, to each existing string with 18 landscape oriented panels i can attach a single portrait oriented panel giving me 19 solar panels in each string. The additional panels will of course be
Adding extra panels to an existing string | DIY Solar Power Forum
Solar Input Max power input – 10400W Max V DC input – 370V (100V~500V) Max current input – 18A + 18A MPPTs – 2 Maybe you can make it three, 8 panels strings. Need to see PV panel specs to check current. If > 9A, then two in parallel would exceed 18A limit. If only 12 panels total, then two strings of 6.
¿Qué es una string fotovoltaica?
Una vez puesto en marcha el sistema, el inversor string está diseñado para captar tanta electricidad como el panel menos eficiente de todo el ramal conectado. Es decir, que si uno de los paneles están generando menos energía, el conjunto se adaptará reduciendo la potencia para evitar puntos calientes o ''hot spots '', que pueden dañar

Strings in parallel with different number of panels : r/solar
Discussion of solar photovoltaic systems, modules, the solar energy business, solar power production, utility-scale, commercial rooftop, residential, off-grid systems and more. I am considering combining two parallel strings of different types of panels to one MPPT, and am curious what you all think the effects will be.
¿Qué es un string en paneles solares y cuál es su función?
2. ¿Cómo configurar un string solar? Para determinar si se trata de una instalación string o conexión en serie, se debe considerar una serie de parámetros como su tamaño, nivel de tensión y corriente.. Esto ayuda a que los módulos solares cuenten con un equilibrio de producción de energía según las máximas y mínimas cifras de voltaje que marque el propio inversor solar.
