Ok, thanks, XXXXX XXXXX
Lets look at the system now, since we dont have any power information or models.
Is it wired like the diagram below? I assume the panels are parallel wired
to maintain wattage, if series I can change the diagram.
Many components are rated for AC and DC, not that many are AC only.
Difference being, on DC the rating is lower in current because of the arcing
when contacts break open and closed.
The wire length requires an increase wire size for the current draw, but without
any wattage,voltage numbers I cannot tell you the size.
#10 minimum and most likely #8 or #6 since the low voltage will have a major
impact on wire length as the current goes upwards.
It is possible to put a relay between the float and the DC power, so the float
switch operates on AC and it turns a relay on and off for the DC to the pump motor.
Very simple setup, but wiring becomes the issue with AC outside because of the safety
involved so it takes more time to install.
Lets go one step at a time and see if the diagram adds any information to the situation.
Let me know.
