Is it possible to have high amps and low volts? : r/electrical
To get a circuit with a very high current and low voltage, you need to minimize voltage drop across everything in the circuit. Wires have resistance. Ergo you need very thick, short wires. As to your question of people being blown off of high voltage wires, most high voltage power lines can ALSO supply a very significant amount of current as well.

On sunny days, Inverter switches off when DC voltage gets too high
I can see from the graphs available that this occurs when the batteries move from 99% to 100% charged and the inverter DC voltage, spikes from 2x 330v (=720v) to 2 x 387v (=774v). At other times of the day, when the battery reaches 100%, the DC voltage is not as high and the inverter does not switch off.

Does an MPPT solar controller, turn excess voltage into
MPPT is a smart DC to DC buck converter. By excess voltage op means panel voltage that is above the battery charge voltage and the answer is YES the MPPT will output more amps and less volts to the battery than it is taking in from the panels and at very high efficiency. A cheap unit I tested earlier today was steady 98.5%.

Why does voltage sign matter for electrical devices and
Yeah, don''t think so much about the actual numbers of the voltage (magnitude), but more so how the voltage is referenced to ground and how current flows in loops. Your power supply is looking for a high voltage at 6.6V and a lower voltage at the GND pin, and current flows from high to low potential.

Why do LEDs burn out?
So if an LED does not burn out, why do these lighting fixtures fail? Why does an LED bulb burn out? One of the main causes of a bulb burn out is that LED technology needs constant voltage, if at any time a power surge is provoked, this causes the temperature of the diodes in the bulb to rise, thus melting the bulb or causing it to fail in a short period of time.

Why does my car battery have a high voltage?
There are a few reasons that can cause your battery to have a high voltage. Your battery could have a loose connection. Loose connections disrupt the flow of electricity so your battery can either be improperly charged or improperly discharged. Symptoms of a loose connector could be your car struggling to start or your headlights being too dim.
What happens if battery voltage is too high?
Weather can affect this range. If the voltage is higher than 12.8 volts, use electrical components to lower it. Managing voltage discharge helps maintain optimal performance and extends battery life. High voltage can also cause gassing, where the battery electrolyte boils away, creating hydrogen gas.
What happens if a battery is overcharged?
Increased wear and tear: High voltage can lead to overcharging. This process stresses the battery components, such as the plates, leading to accelerated deterioration.
What happens if a battery is overheating?
Overheating: Elevated voltage can generate excessive heat within the battery. High temperatures can damage the internal components and lead to thermal runaway, a condition where the battery can heat uncontrollably. Research from the Journal of Power Sources indicates that for every increase of 10 degrees Celsius, battery life can be reduced by 50%.
How does high voltage affect battery life?
Research from the Journal of Power Sources indicates that for every increase of 10 degrees Celsius, battery life can be reduced by 50%. Electrolyte depletion: High voltage levels can cause water in the battery’s electrolyte solution to evaporate at an accelerated rate.
How do I know if my battery is too high?
Turn on your voltmeter and make sure it’s set on the “voltage” setting. Place the red sensor on the positive terminal and the black sensor on the grounded (or negative) terminal. Check to see the reading and if it is over 12.9 volts, your battery may have excessive voltage. 12.6 to 12.8 is the ideal voltage level for your battery.
