6 FAQs about [Maximum battery current of DC system]
What is the maximum current in a battery?
If you "forget about" internal resistance, then the maximum current is infinite. An "ideal" component, non-existent in the real world, can provide mathematically "pure" infinite or zero amounts of resistance, voltage, current, and all the rest. Different battery compositions will have different amounts of real-world "impure" limitations.
Do batteries have a max current drain?
So, yes. Batteries have a max current drain (given by design and physical/chemical limitations) and yes the storage rating (being Ah, Wh or Joules) changes depending on battery design and load applied, and yes Wh is a better way to compare batteries because it takes voltage in account.
How far can a 150A battery be connected to a DC distribution point?
This should be suitable for 150A for distances up to 5 meters. When wiring the system, please make sure that the cross-section of the connection between the batteries and the DC distribution point equals the sum of the required cross-sections of the connections between the distribution point and the DC equipment.
What is the maximum charge current from grid inverter to battery?
What is the Maximum charge current from grid inverter to battery with a MultiPlus II 5Kva. We have 10Kw of lithium, 6.6Kwp solar connected to a fronius 5Kw grid inverter on AC out of a MultiPlus IIGX for offgrid use. We often see the fronius being ramped down and don't know why. The maximum charge current is about 50A, which is about 3200W.
How do you calculate the voltage of a battery?
1) The battery has a maximum power it can provide. For example, if this power is P = 100 W, then since P = RI^2 the current will be I = (P/R)^0.5 = 31.6 amps and the voltage V = RI = 3.16 V. 2) The battery has a maximum current it can provide. For example, if this current is I = 5 A, then V = RI = 0.5 V.
What happens if a DC voltage is increased?
If the DC system voltage is increased, the DC current will drop, and the cables can be thinner. If you want to increase the system voltage, but there are DC loads or DC charge sources that only can deal with 12V, you could consider using DC-DC converters rather than choosing a low voltage for the entire system.
