Sunsynk/Hubble AM2


Recommended Posts

Looking lovely. :)

On the batteries, do you combine them at the fuse box, or use the supplied interlink cable?

I see still using the old solarman dongle, is the new SunSynk one still in beta, or can I buy one anywhere?

Thanks Timcam. 

The interlink cable is hidden in the bottom trunking. Then positive from battery 1 and negative from battery 2 into the fuse box. 

As far as I know, it's still in beta. As soon as it's released, Sunsynk will put out a notice.

Thanks for the quick reply.

On my two hubble's, I've installed bus-bars with the capacity to build up to 10 batteries.

I have fused each battery and use 35mm cable to the bus-bar, and 50mm from the bus-bar to my SunSynk 8.8 kW machine.

One day I hope to be able to go off grid.

This is really killing me, I need it now.😂

@TimCam Fantastic to hear somebody doing it the correct way. Bus-Bars should really be part of any install - most installers dont do it - or if they do, completely undersize the copper in width and thickness.

Always find it amazing that it takes 1 internet search to see what size wiring for size of battery bank is needed - say 50mm for 200Amps - yet people insists on using 25mm - "because it works". Same applies to fuses and bank sizes...how many "standard"  160A DC fuses are used on battery banks of 200,400,600 Amps!? The exact same applies to Bus Bars (Buzzbars? there are so many different spellings!) - a small 10mm wide by 2mm thick is NOT sufficient....

And that age old argument - " A proper bar is another R1000 - and thick battery cables are "expensive"  - another R500 more!" .. after you have just spend R150-R250k on something that needs to last for years. When an electrician (a good one anyways) tells you you need an xyz breaker in your DB and it costs R1000 - nobody cares.. but when people install PV systems they choose the R150 cheap breaker...

Maybe take a picture of it if and share for others to see what we are talking about?

Sunsynk 8kw paired with 2 x Hubble AM2s and 16 x 540w JA Solar panels.

Very neat - impressive.
I see you have the "Legacy" SolarMan WiFi dongle.
Do you have RIOT or SolarAssistant for monitoring the individual batteries?

Thank you. 

No we didn't install a RIOT.

Pics?

No Pics yet, as I have a temporary install (ugly), while building a proper power room for the kit. It is all on the wall which will be broken away to become the doorway to the new power room. 👍 I just couldn't wait with all the kit, and not use it. 😂

Sure, I agree😁, but once it's complete, I'd like to see pics of the busbars, I haven't seen too many of them and I am hugely curious.

Busbars for my system, 48 Volts 1000 Amps. It is wired for 3 x 16kWh packs and dual IkW inverters plus one MPPT PV charger. Each battery wired with 70mm 300A cables and the inverter have dual 70mm cables. The second inverter will be wired on the other side of the busbars.

Total battery supply are 750 Amps with the 3 banks wired. With 2 inverters we need almost 600 Amps at full load and bursting to about 1000 A that for a few seconds. The BYD banks can supply about 1080 Amps for 5 seconds.

That's great Sarel, thank you.

Please would you consider putting a small, well-known object in these photos in future, like a Bic / Zippo lighter or a number 10 spanner? It helps to judge scale and size, your hand does help somewhat, but still a little nebulous because as we all know, the good Lord blessed us all differently.

Some people may be confused by the one small redundant object, most millennials don't use that anymore, replaced by typing instruments….

@SarelI take it those are fuses boltrd on the busbars?

Yes. The 300 A are battery fuses and the 125 A for the MPPT PV charger. There is a small 50A inline fuse right at the PV charge controller output. The 125 A one was as a stopgap measure before I got delivery of the correct fuse.

Thats how fuses need to be installed, bolted down and not to be replaced by anyone, reason of course when a fuse blows, somethin dramatically went wrong and must be investigated.

 

That why I hate cartridge type fuses, which is merely changed by a few flicks of the finger. Convenient, but otherwise incorrect, my opinion. There's of course the risk of bad contact as well
