Under ABYC E-11 the fuse does not always need to be within 7”.

Re: Battery Bank Fuse The possible AC surge from the GVFX 3048E is 5750 VA which would correspond to about 120 DC amps for a 48V system. Here is the table from their installation manual that specifies DC breaker size: Attachment not found. Why their FP1 prewired with this inverter uses a 175 amp (instead of 125 amp) breaker, I have no idea.
Customer ServiceWe protect the bank by inserting a large (400A) Class T Fuse in the NEGATIVE lead just before it attaches to the first battery in the bank. As a last tip let me tell you the best kept secret in the Marine Battery business. Please make sure that the Positive lead to the load comes off the FIRST battery in the parallel bank. Then have the

Customer ServiceFuses are an efficient and effective way to protect a BESS from overcurrents. Overcurrents not only frequently damage systems, but are also the culprit of downtime, which is detrimental to a company''s bottom line. The advantages fuses bring to a BESS are immense.
Customer ServiceFusing at the battery bank is a good idea if you have parallel battery strings (typically 3 or more parallel, one fuse/breaker per parallel string). Technically, the fuse/breaker is to stop high current from the battery bank from starting a fire if there is a short.
Customer ServiceFuses provided for battery overcurrent protection including short circuit protection shall be evaluated for both short circuit and overload conditions. Fuses that are evaluated for short circuit conditions only (type aR fuses), shall be provided with supplementary protection (e.g. the BMS [battery management system]) to ensure protection under overcurrent conditions in ranges
Customer ServiceHi guys What is the proper way to protect battery banks with fuses? My current installation (4 x 4 strings 12V) does not have any fuses on it. There is a breaker between the inverter and the battery bank but no fuses. Should each individual battery have a fuse (between the 4 batteries in a string...

Customer ServiceMy boat has a main bank fuse, but it is at the DC buss, about 8 ft from bank. The battery cables are run in PVC conduit to opposite sides of the DC panel so a short is unlikely. But it is certified as ABYC compliant so I wonder if they got an exception? Easily fixed with a 1 foot cable, and a fuse block in battery box.
Customer ServiceRe: Fusing of battery bank You can use the class T fuses. If you can prevent too much stress from 2/0 cabling you might do it with lug fuses without holders. Usually easiest to prevent cable stress on fuse by putting in middle of series string.

Customer ServiceIndividual battery bank string fuses should be as large as the main inverter fuse. Some would argue it should be 1/3 in such a case, but if the current draw shifts or one of the fuses blows then the other(s) take on more load. The purpose of these is to prevent massive discharge in the event of a dead short like a dropped wrench. That''s why the
Customer ServiceFor safety reasons, the shunt is typically placed in the negative cable. It should be the last component before the battery bank or battery bank busbar. All DC consumers and supplies must be connected after the shunt. Refer to the diagram

Customer ServiceIn this article we will discuss fuse selection, fuse types, wire ampacity, Amperage Interrupt Capacity (AIC) and even potentially unsafe ABYC "exceptions to the rules". In short, this article deals with why fusing your battery banks is a critical safety measure. IMPORTANT: Every DC positive conductor on the boat requires OCP!
Customer ServiceClass T fuses, filled with ceramic or sand materials, are ideal for lithium or high-current battery banks. Avoid using automotive blade or glass tube fuses for solar or lithium battery applications. To ensure the safety and quality of your fuses, stick with reputable brands like Siemens, Little Fuse, or Bussmann, and always check for UL listings.
Customer ServiceThe main bank fuses are there to prevent the wire from overheating, melting and starting a fire in a dead short situation. Generally speaking a fuse is sized to not exceed the maximum ampacity of the wire. In certain instances the ABYC allows for up to 150% of the chart below.
The ABYC Standards on Battery Bank Fusing: Fuse Location: The ABYC requirement is for a battery bank fuse is to be within 7 wire inches of the battery bank. The European ISO/RCD (which is law) requires the fuse be within 200mm. 200mm equates to about 7.9”. In this regard, the European ISO/RCD is essentially the same as the ABYC’s 7” requirement.

They often lack the necessary interrupt current rating for a lithium battery bank, posing a significant risk. There are various fuses to consider, such as blade-style, ANL fuses, and standard 10x38 fuses. Blade-style fuses, common in automotive applications, aren't typically suitable for lithium battery systems.
It is correct that you protect the cables but also the battery strings if you have more than one. So you must have the fuse on the batterys and that for every string. I personal put a second fuse also in the middle from every string. that to avoid a tool shorting the battery terminals ( yes it happens ).
