Max input voltage/amperage for MPPT charge controller
Normally an MPPT charger is rated for the amps that it puts into the battery. The current from the panels is a concern for your wiring size. By design most MPPT chargers are "buck" type converters, bringing a higher DC volts down to a lower DC volts (to the battery). So the current from the panels will be less than the current to the battery.
Oversizing a PV Array (within max Voc and Isc) can do any damage
The maximum Isc (input short circuit current on the PV panels) is a limitation of the reverse polarity protection within the MPPT for the PV array. If you connect a PV array in reverse polarity that is below the short circuit current limit, then the MPPT has a protection circuit that will allow you disconnect the PV array, reconnect it and have the MPPT continue to operate without any
BMS Overcurrent Protection: Indispensable for Battery

6 FAQs about [What happens if the battery exceeds the maximum current]
How can a BMS limit the flow of a battery?
b. Current limiting: Sometimes the BMS will limit the flow of current so that it is within safe limits. You can achieve this by actively modifying the charging or discharging current of the battery to guarantee it stays below a predetermined threshold.
Does a battery charger need to be told the maximum current?
Contrary to what some comments/answers may suggest, the charger needs to be told the maximum current to deliver. They normally don't/can't 'sense' it. The important thing is to use the correct battery charger circuitry based on the chemistry of the battery.
What happens if a BMS overcurrents a battery?
a. Current disconnect: One of the most common responses to an overcurrent is to disconnect the battery charging or discharging circuits. The BMS can quickly stop the flow of current by disconnecting the associated relay or transistor.
How does battery life affect the life of a battery?
The life of the battery is related to the current it receives. Excessive current can trigger chemical reactions inside the battery, leading to battery polarization or electrolyte loss, which will accelerate the aging process of the battery and shorten the battery life.
What happens if a battery gets a thermal runaway?
Thermal Runaway can happen. The battery can't physically/chemically store the energy if delivered too fast, so it is dissipated as heat. Contrary to what some comments/answers may suggest, the charger needs to be told the maximum current to deliver. They normally don't/can't 'sense' it.
What happens if a battery overheats?
In some cases, excessive current may cause the battery to overheat and cause a fire or explosion. This is especially dangerous for applications such as electric vehicles and energy storage systems, which use high-capacity and high-power battery packs.
