I have Trina 415w panels, on the back it states power voltage as 41.7v and open circuit voltage of 50.0v
Are Victron mppt voltages listed for open circuit of power voltage?
If I got a 100/50 for two series panels that's 100v open circuit and 83.4v power voltage, so which applies for a 100/50 mppt?
Open circuit. Connect in parallel.
It depends what system voltage you have...
1) In case of 12V, put em parallel but the 100/50 will not deliver the maximum power of the two 415Wp panels. If you WANT the maximum power, then go with the 150/60 and put the panels in series which will give you an enormous advantage from autumn to spring.
2) In case of 24V, parallel works, but you go better with a 150/35 and put the strings in series
The 4 panels in question will go on my shed roof. I was planning to connect two in series, and the two strings in parallel, which gives 100v open circuit and 20a short circuit, so what mppt should I use? Also with a view of adding a further 4 panels in a location next toy shed, which would give 100v open circuit and 40a short circuit. Would a 100/50 still be ok or should I go for a 150/60?
