i have 2 questions and this is my first time on here i recently brought 2 multiplus inverters and parallel them no problem all seems good on my test before i put then up permantly there is a red and black lead that comes with both units and ill be honest i dont know where there should go i does seen strangeas the red and black it only had 1 ring hole about 3/8 big the othere end clearly 2 wires so thats the first question i also have a battey alarn with heaps of switches witch seems easy enough to hook up but settting for high is 16.5 at max and i need 17 or off all togeather the main reason for this item is to let us know the the system is low so back off on power plus it seems i have to put a pin on both poles on the back....not + - side
