Hi
Wold like to know have 2 group of 4 48v 500w panels.
Whar is best installing parallel all the way or connecting in the end connecting the groups series or in series then in parralell to get 96v.
Plse explain what is the best
Regards
Bob

What are the "2 groups" of panels? Going to two separate charge controllers? Two different "planes" of panels (facing South East / South West, different tilt)?

Hi Bill
NO only to one charge controller 48v peanels vmp48.63 voc 58.95 imp 10.87 must hybrid inverter max pv array voltage 145 vdc max
what is better connecting each array of 4 panels parallel and then on the end each array in series to get 96 volt
Or all 2 array in series on the connecting both parallel to form 96 volt?
all facing south am in curacao 12,2 degree
Awaiting your reply

Oh yea--You are the guy living the tropical paradise!
Can you tell me exactly which Hybrid Converter you are using (model name and/or link)?

Yours is the last column (48 VDC battery bank)
For example:
From your original thread:
https://forum.solar-electric.com/discussion/355773/dstance-panels-and-inverter
You put two panels in series. And typically, with 3 or more parallel strings, you should have a series fuse per string (typically ~15 amps or possibly 20 amps for these panels--Check the label).
You have 8 panels (?) and they will be 2x panels in series (2x Voc / Vmp), times 4 parallel strings (4x Isc / 4x Imp). Depending on what hardware you can get there, we typically use solar combiner boxes with have 4+ fuses or circuit breakers (one to each string--basically the "reverse" of a normal home circuit breaker--Multiple panel circuits in, one set of wires out to charger). The fuses/breakers are to prevent a single shorted panel (or wiring) from being feed current from the other (3) parallel strings:

Or, you can probably build something from local components... Make sure the fuses/breakers are rated for >60 VDC and 15 or 20 amp fuse/breaker (again, see label on panel for proper series fuse rating).
You can bring 4x groups of wire from the array to your home/battery shed and then wire in the combiner box with a short connection to the hybrid inverter/charger... Or you can put the combiner box at the array, and run just 2x heavier set of cables from the array to the shed/inverter... Make sure the wiring is UV (outdoor sun/weather) rated--Or that you have the cable in conduit to protect the wiring.
