Yes, that looks like the right fuse for your application. (Be sure to use a battery cable with at least 250A ampacity.) Two reasons for...

Thanks, I use search exhaustively but for some reason I didn’t run into this. The pushbutton design looks good. This is a problem I did...

[Search] for "Precharge" in Resources: https://diysolarforum.com/search/2241304/?q=precharge&t=resource&o=relevance Can also search...

Got it, thanks. Where can I get more info on building something like this? I'm using a resistor as seen in Will's videos, but I see...

What about something like this to kill 2 birds with one stone...

Got it. 250A seems to still cover my use case with the additional +12%, which would put me at ~247A. Would something like this work...

I would multiply by an additional 1.12x for "Ripple Factor". Current coming from battery isn't the DC average power, it is rectified 60...

What Class-T fuse do you guys recommend? I'm going by a basic formula I saw on the forum (thanks @John Frum!), starting with inverter...

That doesn't seem bad at all, which ~15kWh prebuilt have you priced that competes with a delivery kit for only that much more?

Nope, not allowed currently. They don't even allow you to build your own UL9540 system out of UL1973 batteries. They won't even send...

From here https://diysolarforum.com/resources/dc-fuse-and-breaker-sizing-and-placement.129/ “The Amperage Interrupt Capacity (AIC)...

Inverters sometimes release the magic smoke in the mosfets and short out the input, so that's when you need the fuse to kick in...

As a matter of policy I size the rest of the system components based on the max continuous rating of the inverter. For a high frequency...

I don't see any. If someone were visually impaired and thin heat shrink were used you could feel the + / - but someone visually...

So, basically, no real point in using +/- if you're gonna wrap the ends, right?

I've been very happy with it. One thing to note, I found the recommended pump chart to be way to low. I'd say ~7 more than the chart...

The thickness of lug metal is very important. Cheap lugs are formed from thin copper. Think about the hollow tube from where the...

I used the cutter Will references on his site. I first position the wire next to the lug and mark it with painters tape. I then...

For battery cables, which have softer insulation than house wire, the trick is to not cut quite all the way through with the cutters...

This looks like the best crimper out there, especially for the money (let's call it up to $100). The fact that it's dieless is a huge...
