6 FAQs about [DC battery bank fuse configuration]
Should a DC system have a main fuse?
A DC system should always contain a main fuse. Removing the fuse will also break the circuit. So, when the system needs to be maintained or if the battery needs to be replaced, removing the main fuse will be sufficient to isolate the battery from the rest of the system. Always use quality isolator switches.
How do I configure a battery bank?
Configurations are possible for AmpHour capacities from as little as 300 AmpHours to over 4000. To use the Designer, follow these 4 simple steps : Click 2, 4, 6, or 12 volt batteries to build your Battery Bank. Select the closest AmpHour rating for 1 battery. Select the size of the Battery Bank capacity in AmpHours.
Where should a battery bank be connected?
If the system has only one battery bank you should connect the battery bank in the middle of the busbars. But in the case of several parallel battery banks or smart batteries, they should also be distributed evenly along the busbars. If the system has individual batteries, also intermix these with the inverter/chargers and the solar chargers.
Can a DC fuses be used in both AC and DC?
Most DC fuses are suitable for 12 and 24 V, but they are not necessarily suitable for 48 V and higher. Please note that not all fuses or circuit breakers can be used in both AC and DC circuits. If the fuse is able to be used for both AC and DC, the voltage for AC is often rated higher than the DC voltage rating.
Can a NH fuse be used as a circuit breaker?
Victron Energy Battery Switch ON/OFF 275A. High current DC MCB. NH fuse holders can be used as a circuit breaker. Each unit must be fused individually, using the same type of fuse for each unit. This ensures that each DC path has the same resistance. Avoid using a single large circuit breaker or fuse for the entire system.
How do I determine the amphour capacity of my battery bank?
To determine the AmpHour capacity you will need, use our System Sizing Estimator which will calculate the AmpHour capacity of your battery bank and also the number of solar panels required. Select the voltage of the batteries to use in the battery bank . Select the System Voltage for the entire battery bank.
