Cool, I like the idea of adding those big old battery switches, a prudent decision. One thing perhaps worth mentioning is that when considering main or service disconnect switches, is the current interrupting rating, or the rated maximum amount of current that the device can reliably interrupt when under a load over it's rated constant current capacity. Or basically how big of an instantaneous short-circuit current can it withstand and still open a circuit without the contacts welding closed or blowing apart. On a 250v 30amp frame circuit breaker that might see that rating at 50,000 amps, but battery disconnects such as you have there are not typically rated as or considered as a 'Disconnecting Device" like a circuit breaker or mains disconnect switch, but rather just switch, like a light switch that is protected by a short-circuit protection device such as a fuse or an over current device such as a circuit breaker. with your fuses in line with that switch it's protected from over-current damage and therefore functions as simply a disconnect switch, and not an over-current protection device or emergency over-current disconnect.

It's typical for switches to have a label next to them saying "Do not operate under load". The load for this switch will be 100A max and it is capable of switching 300A-900A. I would still not recommend doing it as these switches don't have a arc chamber inside like the circuit breakers have.

All good points here. I have purchased a similar marine type switch, but have also been considering the pro’s n cons of using a contactor as a main interrupt mechanism, what do you think Andy? Is there a reason not to use large contactors? I have seen them on Ebay 400-600Amp 12v-60v solenoid ranges for $100-$150ea. A large contactor could be controlled with smaller switch’s , DIN rail mounted in your dust proof enclosure, etc, with a host of other safety features being able to be built in with an electrical contactor as a main or backup current interrupt. I do like ur No Ark’s though they do look pricey and a fair bit more to mount and configure. Love ur vids Andy

@@evil17 Personalty, I think a contactor could be useful and prudent. That's what's most EV use in conjunction with a smart safety system but I would not use one as the the only overload, short-circuit and disconnecting mechanism. I've seen a lot of AC contractors weld closed as they have only a little spring to push the contacts open. Instant trip breakers that use electronic current sensing rather than a thermal spring to trip, are often motorized or use a powerful mouse trap/solenoid trip to drive the contacts open. When using a contactor on high-amp DC systems with large inrush current to caps on inverters, I'd want a fuse and/or circuit breaker. For protection incase the control circuit did not work or the contacts happened to weld closed.

I would have preferred to move the two mega fuses to be on top of the cables instead of underneath. Should you need to replace a fuse, you are going to need to remove the cable and put it somewhere while the new fuse goes in. Not sure if those cables will short something if they touch anything in there but I feel that it would be far safer if the cables stay in place during a fuse change... That would be Geil.... Just like Bruce and Bongo in their famous song LoL 🤣
@OffGridGarageAustralia
@OffGridGarageAustralia 2 жыл бұрын
I hope I will never have to replace these fuses. The inverter should actually shutdown itself due to overload long before that. If I change them, I would turn off the main breaker anyway which isolates the bus bar. It is far too dangerous to work on a live system which such a power.

@Bastler95m 2 жыл бұрын
you could have gone with the 60V DC rated C125 breakers instead of the fuses? they can take up to 50mm² wire/cable and you can use them as main switch for your inverter. I personally would work on the 48V live, none of the poles seems to be connected to the chassis and ground so if I touch only one pole I'm either connected to only the positive or the negative. But turning everything off is still right, especially if you feel uncomfortable working on the 48V. I work on 24V everytime without turning off the powersupply and those are grounded to earth ground on the negative side.

Victron recommends the 200A fuses for these inverters so I went that. Apparently there are some DC breakers out there with larger terminals but none of them can fit a 70mm cable (again a recommendation from Victron for this inverter to minimise ripple under high load). I also would not have been able to fit a 70mm cable into the switchboard at the front without any custom made busbar links.
@evil17
@evil17 2 жыл бұрын
Andy, have you given any consideration to using large Maxwell Capaitors, (possibly very close to the inverters) to help smooth any potential ripple and load share the peaks as pumps, heavy loads, etc , on start up? I dont know if this lifepo4 chemistry is making large capaitor banks at the inverter nearly obsolete nowadays compared to the huge advantages it has given to other chemistries in the past. I recently purchased a heap of Maxwell 16v strings and a few 48v banks as well, as are used in trains, elevators, etc, because I believe they do help tremendously as an extra high current buffer, particularly when coupled directly to the inverter with heavy cabling. Cheers

Hi, personally. I would prefer using them. I have seen mighty sparks in a 48v hybrid inverter just about when the battery breaker was switched on. In fact that unit had to be returned. From what I have learned, the longer the inverter has been switched off or in storage, the bigger the spark. The input capacitors will have no charge at those times and will act as a short. When.the unit is switched on, the batteries send a high inrush current, hence the spark. I have experienced a BMS shut down when a battery breaker was switched on and the last case was with AGM's. Sometimes the sparks eat out at the battery terminals too. Better safe than sorry. Check out this video: kzbin.info/www/bejne/pHquZ5udoZiEkNk
