Hey Track! please, explain to me how low voltage burns up electronic circuits found in appliances, computers and alike. We will start there and then I have other questions about your post. Thanks!
Sir, believe it or not this is basic and simple ohm's law, I=V/R, ( It's was taught in physics class in Junior High Or what ever they call it now.
I will first try explain it using the cables on the inverter.
The cables on the battery that go to the inverter (DC Side ) are very thick because the voltage ( 12- 48 VDC ) is very low and the current are very high. If you connect the battery using small conductor " AWG 12, 10, 8 etc , The wire will produce lots of heat, and it will conduct the heat all over. This will heat up the poles in the battery and also the connectors to the inverter, all the way to the circuit board, if it keeps happening then the heat will melt the led on the battery poles and/or the solder on the inverter and who knows. At the same time the voltage to the input of the inverter is less than, making it work harder. ( More things happen at the same time ).
I know this is not a great "Theoretical" example, but in it one could see how the wire size will F..K things up.
It's a bit the same when you have a bad contact on the breakers. It will heat the beaker, lower voltage to the "device" or TV and it has to work harder because it sense lower voltage ( Again, lower voltage, more current to maintain the the power consumption.) That is directly proportional to more heat.
The end result could be a broken "device" or TV, Radio, Washing Machine, etc. The ignorant repair person could tell the "Americano" it was a surge, spike, or some other sh..t. and you will believe it.
Unfortunately I must also say this, If it's sold in "La Sirena" it's probably not a good quality inverter. For example, a Xantrex inverter has very limited protection in the input side, They have slow responding components called MOV, (Metal Oxide Varistors). They will work fine when you have a high voltage for a few seconds, but in a surge ( transient voltage ) They work a bit laid back. Quality components use Gas Tubes, MOV, SOV, and other to archive high speed response.
It is my understanding that the inverter acts like a surge protector evening out the current (I'm a bean counter not a sparkie so don't shoot me!). If the stove was connected to the inverter, it shouldn't be affected.
When the inverter is charging and/or not inverting, it does almost nothing to surge or spike. On the contrary, when it's charging the battery bank it draw high current from the utility company (EdeSur, EdeEste, EdeNorte, or What ever ). This could cause low voltage, high heat, etc. ( Here we go again )..
