Multiplus II and Battery current limiting
So the Multiplus will be connected to the grid, and the BYD battery will serve to provide power if the grid goes off. The system only need to be able to supply about 2 to 2.5kw max. So is it possible to set the maximum discharge current from the battery to 2.6kw, or otherwise, can the Multiplus be set to output to a maximum of 2.6kw? Thanks

6 FAQs about [Maximum current output of the battery]
How much current can a lithium ion battery supply?
The higher the internal resistance, the lower the maximum current that can be supplied. For example, a lead acid battery has an internal resistance of about 0.01 ohms and can supply a maximum current of 1000 amps. A Lithium-ion battery has an internal resistance of about 0.001 ohms and can supply a maximum current of 10,000 amps.
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.
How much current can a battery supply?
A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
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 many amps can a 12V battery supply?
Assuming you have a 12V battery that is in good condition, it can supply up to 30 amps of current. The amount of current that a battery can provide depends on its size and capacity. A larger battery will be able to provide more current than a smaller one. How Batteries are Rated?
What is a good battery capacity?
So for any sensible lifespan you are looking at a useful maximum of around 30mA. Battery capacity is usually a measure of AH capacity and is based on physical size rather than rated voltage. In essence a large battery has greater capacity than a smaller one of the same voltage and hence may be considered as capable of greater current capability.
