Can someone help me with learning some DC basics for solar design.
How do I calculate losses in 3-5mm wire power cables used in dc 14.2volt 6Amp(max) Wiring is from a nominal 12V dc solar power source, 5-10metres distance to battery storage, and from the storage approx 5-7metre the load.
So if you can help me with some free advice or teachings on
design and calculating basic dc circuits. want to learn the old school way with brain, pencil and paper working.
very happy to know where any great free, design tools or calculators suitable for simple loads12/24VDC equations drawing between 1 and 6 amps per hour.
Especially: want to understand cable or system loss calculations
Cheers
