I would like to extend the cable length on this sensor. My question is what type of wiring is needed to do this? I would like to go 130 feet away from the battery location.
Thanks for any info.

Hello Patrick, you need to install your equipment according to code rules. This would provide the safety necessary for your installation. Your concern about the high current drawn on the batteries is valid. You have to do a little math in balancing your system so it works propperly.

Where will the system be installed? Fixed residential? Portable remote locations?

Does your inverter have a floating NEUTRAL? 

Your inverter (3000 watts) cannot be loaded to its maximum rating for a prolong time. I would suggest you limit your maximum load to 80 percent capacity (2400 watts).

Your calculation regarding currend drawn is correct and is not a problem once you install the devices in the propper enclosure and use the propper size of conductors required to handle the amperage drawn. Visit your local electrical supply store for the propper equipment required. Correct fuse sizes for circuit protection is required. Locate the inverter as close as possible to the battery bank. Extreme care should be exercised in connecting batteries to the inverter. A shorted battery can deliver very high currents (1000 amps).

The 24.4 volts DC you measured is the open circuit voltage of the panel (no load connected)check panel specifications.

I realize you are embarking on a project with limited knowledge. I would suggest you do some reading on the subject to expand your knowledge base. Take your time and do it right. Be cautious in your approach, electricity KILLS! Install acccording to electrical code rules.

Regards, Romeo
