Sizing MPPT Charge Controllers
That is great for a 150V rated charge controller, but too high for a 100V. The third rating is the output current. This is a simple equation. Watts ÷ Volts = Amps. You take the total watts of the solar array divided by the voltage of the battery bank. That will give you the output current of the charge controller.
Multiplus ignores AC input when battery is too low
In my setting I have "DC input low-shutdown=18.90V, DC input low restart=20.60V", If my battery voltage is bellow 20.60V and there was an invertor shutdown (either manual or because batteries got bellow 18.90V) Multiplus does not accepts AC input no matter what.

Why do car starter motors draw so much current?
All electric motors consume more current at startup compared to steady state. Check out the label on your fridge for example (or look at this one): the max current on the label is 2-3 times higher than the value you''d obtain from power to voltage ratio.. The reason behind this lies in the properties of electric motors.

Also, make sure that the battery is not flat-out dead. The charging current is too low: Check the temperature of the IC, that is if the generated heat does not dissipate the charging current will be limited by the IC. Also, with USB input pin the charging current is limited to 100mA. for the maximum charging current use, the DC input.

Transformers | Physics
As expected, the current output is significantly less than the input. In certain spectacular demonstrations, very large voltages are used to produce long arcs, but they are relatively safe because the transformer output does not supply a large current. Note that the power input here is P p = I p V p = (10.00 A)(120 V) = 1.20
power-supply voltage current theory
$begingroup$ I suspect they themselves don''t quite know what they mean by ''drawing'' current. However, a "load" is essentially a device to which power is delivered.Thus, increasing the load on, e.g, a motor, requires the motor to deliver more power and, assuming the voltage to the motor is (more or less) constant, this means an …
Are too high capacitance capacitors "bad" for the circuit?
$begingroup$ @mkeith I realize that there''s no universal best capacitor. I was just wondering what behavior a too big one actually displays and/or what effect it has on the current. The "know what you are doing" can only be achieved by learning and knowing at least some of the behaviors I can understand the topic easier without DIY …

For this, the bigger the capacitor the bigger will be protection. Of course using too large ones for the application will be a waste of money and space. Noise: Inductive loads causes lots of noise on the power rails. For this you can protect the sensor adding capacitors with the right values across motor input poles.

Demystifying Input Supply Current in DC/DC …
input current depends on the input voltage, output voltage and other factors. You can see that the input current will increase for larger output voltages and smaller input voltages. So the best thing to do is to use the equations to estimate the no-load input supply current and then measure the actual value under real application conditions.

$begingroup$ As a little "information for the layman": Theoretical power supplies can output infinite current. Practical power supplies have an internal resistor that is the sum of all the wiring and other components. In the model of such a power supply, the resistor is what causes voltage to drop as current increases.
Battery Banks & Over-Current Protection
In regards to over-current protection of battery banks, owners should consider that the ABYC standards are a bare minimum requirement. In many cases, especially battery bank protection, certain aspects of ABYC E-11''s battery bank over-current protection should be considered as inadequate, potentially unsafe and below where a boat-owner should set …
Ohm''s Law Calculator
Ohm''s law states that the current flows through a conductor at a rate that is proportional to the voltage between the ends of this conductor. In other words, the relationship between voltage and current is constant: I/V = const. The Ohm''s law formula can be used to calculate the resistance as the quotient of the voltage and current.

The AC Input Control can be set up in numerous ways, for example, the Multi will disconnect from the grid when the batteries are full enough and/or the AC load is not too big. The Multi will disconnect from the grid most of the time. It will only let the grid in when the batteries are empty or when you are running a big AC load.

Current: A device that draws a specified current can be operated from a supply able to supply the same or higher current. eg consider a 12V, 2A device and a 12V 20A power supply. 12V is the "electrical pressure". 20A is the electrical current that the supply CAN provide at that pressure. 2A is the current that the load WILL take at that pressure.
How to size an in-line fuse for the input of the DC-DC power supply
One thing that could cause a fuse to nuissance blow is short bursts of high current when a battery is connected to a power supply with input capacitors. In your case, the battery has the ability to deliver very high current upon initial connection. So you may get large inrush currents. This is why I have gone to a larger fuse.
