Ampster

I think the default is that each battery has equal access to the charge current. I never got a clear answer from tech support about the...

I believe some of the HV batteries BMS configurations do this kind of inter module balancing.

The grid dependency has been mentioned, so they aren't a good choice. For a string inverter, it usually has more than one string so...

I've pointed a lot of people to that thread. It's probably the best thread here for explaining why paralleled batteries get out of balance.

That is a good read. In some situations balancing batteries is not an issue. In my former 3P16S pack the parallel cells by nature are...

In my usituation i used Pytes rack batteries and their cabinet which held four. The cabinet came with cables and busbars. The cables...

I personally don't see any problem with the aluminum bus bar it seems plenty overkill for the situation. I would be more concerned with...

I've seen a number of busbar solutions where the busbar is run next to the set of rack mount batteries and a short cable is used to...

Yes, in an enclosure this can be a good solution. EG4's battery racks use such an arrangement.

See the chart in the link below. It backs up Ampster's .5"x2.0" amp rating. https://dctechcorp.net/images/busbar%20ampacities.pdf

I understand your assumption. I still don't understand what load you assumed was going to make those busbars "red hot"? My...

My math was done prior to his mentioning the inverter he was using. At that point all I had to go on was 5 batteries capable of...

How about this:

I did not say that. I made it clear that Aluminum has an important role in the world of electrical distribution. Whether the busbars are...

In the industrial market, they aren't. If you see transmission cables out in the open they're aluminum. That was the whole point of...

That is a good approach until you acquire the knowledge and skills of those experts. I am not arguing for Aluminum or trying to change...

Because at the DIY level, copper is simple and not much more expensive. Turning that argument around, why are all electrical...

Is there something incorrect about either of these assertions? This whole thread is about the possible challenges with the aluminum bus...

Yes, because they were copper coated Aluminum and I was fooled by that and undersized them for the load they were carrying. If I had...

Yes, all long distance transmission lines have been Aluminum for decades. Even the last mile of distribution such as underground and...
