Hello there,
need some advise.
Am using 6mm sq copper single core wires to connect 24V Solar panels of ~300W to SCC placed inhouse.
Since install distance is 20 meters and there is room for future expansions(30A), 6mm was kind of safe to go with.
Later, I planned to place relays on the path to solar panels which could be managed via a separate circuitry.
When checking Voltage Drop across the each wire with 1Amp current input, following readings were noted:
-> Direct Connection - voltage drop of 0.108v (20 meters length)
-> Routed via Relays - voltage drop of 0.112v (20 meters length)
Curious to know from Electrical engineers - How much Amperage capacity is being degraded by adding the relay
which is inducing a 4mV voltage drop?
Because if that's significant - shall put a single big relay or change relay connections with thicker wires.
Thanks for reading through. Please post your valuable comments.
Regards
