Posted January 16, 20223 yr This is a stupid question, but rather safe than sorry, so am asking. Hubble's manual / paperwork / etc online isn't fantastic already, and I looked at every single install pic I could find on here, but none show the terminals. I labelled the pic below 1 to 4. Which of the terminals do I connect my cables to? My connector under my battery is red and black though, but not sure if I use 1 & 3 or 2 & 4, or it doesn't matter. At the moment I have a single battery only with a SunSynk 5.5 inverter. And on the DIP switches just the 1 up, the other three down? Thanks.
January 16, 20223 yr 1 & 2 are positive (+), and are common. Electrically they are the same point, so either one can be used. 3 & 4 are negative (-) and are also common. This is done to connect more than one battery in parallel. Like you thought, just use 1(+) and 3(-) with one battery.
January 16, 20223 yr Author Thanks - just wasn't sure if they were common the + + and the - - . Appreciate the feedback and help. Hubble, a single line in your documentation would be appreciated. 😅

About the only thing. 😂 As one who works though loads of documention to go out, I can confirm two things doing the install: Hubble and SunSynk are definitely competing for lack of crucial details in both their documentation offerings. So I step back and say "well, probably this is designed to be installed exclusively by professionals". But no, I see the same very "professionals" asking similar questions in months / years back if I scrub through the forums / online. So even in context, it shows a complete lack of UX thinking of the end purchaser. SunSynk for example goes on and on about the importance of a CT coil, and even that it MUST be the right way!!!!! (insert extra exclamation marks) but never actually says WHICH way the arrow must point. Is it to the municipal meter? Is it to the main switch DB load? Who the hell knows (if you were to read the manual exclusively). What I have seen is that there is a MASSIVE (Gupta sized 😅) gap in the market for someone to do some great CLEAR instructions / diagrams for installs using a range of standardised parts. No one wants to invest in this, and that's a pity. There's amazing resources here, but a simplified drawing / specs... "put this here" "connect this here" etc... would work so well. Maybe when done I'll draw up clear ones and share. 🤓

I knew I'd seen it - and a quick check shows the same "table" for DIP switch settings (atttached from ONLINE PDF manual). Yet, on the single page "manual" (with same table) that ships with the battery, there is only talk of multiple batteries. ie. logic in that case would say for single one all DIP switches would remain down in the off position. Again, a variance and easily solved as we go in with loads of reading, by why on earth omit that one sentence in the paper manual (one pager) shipped with the battery. Bizarre.

I think, as someone who does documentation and approves it, the ommission of saying which way the arrow must point on the CT Coil is a massive oversight. Then that whole little diagram wouldn't even be needed, as everyone would have it the right way from the beginning. When engineers or tech's write instructions this is the usual oversights.

It specifically says that if there is a negative CT value when importing from the Grid then it's the wrong way around. So don't understand your confusion

So don't understand your confusion Yes, it DOES say that, but surely it's EASIER to say direction of arrow and then the part you're quoting it a moot point altogether. So I must fit it, hoping it's correct, then start up the inverter to know if it's right or wrong, and 50% chance have to re-do the install? I'm not sure about you, but doing work twice isn't for me. To any logic or reason based person, this is an oversight in documention that can solved with a simple single sentence, or diagram (which exists) but showing arrow direction. So easy. I literally found over a dozen threads on here and even SunSynk's own website forum asking the same thing. I'm not alone.

No INSTALLER completes an installation without running tests. There is definitely no need to REDO an install. It's a simple matter of swapping the CT wires around in the inverter, you don't even need to change the direction of the CT in the DB.

Just a stickler for good documentation. Of course testing is required, but just imagine... it all works first time. Life changing!

Life changing! Commissioning a mere inverter and it functioning perfectly at the onset is something I don't deem as a life changing moment. But I guess it's special for some.
