Hi guys.
So finally I have bought an inverter , EaSun SM IV 5.6KW and in the first phase I had 8 panels in series :
VOC 41.3 , MPP Voltage 34.8V at 10Amps. - 380W each.
Everything worked according to plan and I was satisfied with the final results and the installation itself.
After 2 weeks , I decided to add a few more panels and I have bought 4 more (minimum order was 4).
Connecting 12 in series will trigger the system overload on the PV as the Max. PV Array Open Circuit Voltage is 450V.
I was thinking to go with 2 parallel strings of 6 panels or go with 11 in series (11 in series would mean 454.3V for VOC) ?
When I go with :
2 strings of 6 I would have 20amps but only 208.8V and 2280wat per string thus 4560W total.
1 string of 11 at 10 amps will 382.8V and 4180W
From PV to the inverter I have around 20-25m.
I only use around 2200Watt when I run everything connected to this but in a normal day operation the consumption is around 400 watt but I would always use the surplus
to charge the 225AH 48V flooded battery bank.
So what would you guys recommend ?
