Q: what is the white wire for?
尋ねた BG131214613 に 2022-07-23 17:39:58
notyoung Red is positive power. Black is negative power. White goes to voltage to be read. Back of PCB has "Vin".

notyoung No. The two inputs are simply in parallel to allow using smaller wire from the solar panels. Be aware that the PowMr has limits on the lowest and highest solar panel voltages for a given battery bank, such as 20-80 volts solar for a 12 volt battery. Read the manual carefully and be very aware that the PowMr REQUIRES at least 20 volts solar input for a 12 volt battery. That means a single 100 watt panel will probably NOT work as the panel's under-load voltage will be in the range of 17-18 volts and that's not enough.

Q: Good day. Can I test 1.5V,4V and 9V Batteries with this multimeter?

notyoung You can measure the voltage of the batteries but that tells you very little about the battery's remaining capacity. For that, you need a battery tester which tests the battery under load.

notyoung No wattage ratings. The 4 models are rated in lumens: A=1000, B=1500, C=3000, D=4500. You can find charts of "lumens to incandescent watts" online.
