Nickel2,

The crocodile clip 'fuses' are balance lines the same as nowty used, the inter bank fuses have soldered ring terminals.

Good Afternoon All,

That's the 5kWh Growatt battery turned up today so Philips/ Pozidrive screwdriver and 10mm socket driver at the ready.........

When I get back to the house I can charge up each module.

Regards

Richard

nowty,

At least mine was only 44 and not 63kg!

All my lifting gear has been legitimately acquired from offshore over a number of years - comes in handy when needed. I haven't had an excuse for using a Tirfor in ages though.........

Sat here drinking the first mug of tea for the day and psyching myself up to replace/ re-wire the outbuildings CU.

The McDonald & Munro Speyside Stages Rally is due through the Whitehaugh forest at the back of the us today. It is a closed stage but I might find my way up there.

Useless fact for the day. The battery modules/ cases in a Growatt are the same physical size in both the 2.7 and 5kWh devices.

Regards

Richard

Good Morning All,

What other way to spend an Easter weekend but working on an RE project??

Beginners Error No. 1 - remember to tighten cable glands from the left as you go otherwise you have to remove things to access the glands........ I was going to say that's the SI 4.4M-12 wired up but looking at the photo I can see Error No.3 for the morning. I've forgotten to put the ferrite on the battery temperature lead so the cover will need to come off........

Beginners Error No.2 - I didn't order an adapter to fit the cable gland for a 6mm2 T&E cable in to a 32mm gland hole so I've fashioned a crude 'spacer using some sheet aluminium.

Growatt batteries currently being charged. The modules were all circa 3.2V.

Regards

Richard

Good Afternoon All,

Well as I sit here with yet another mug of tea the new CU install continues. I've also put the ferrite on the Battery Temperature sensor lead. The double socket under the CU will definitely need re-locating.

Currently no power going to the domestic water pump but still enough water coming out to fill the kettle  Smiley

I'm assuming the rally cars must do between 2 and 3 circuits of the forest as they went past several times....

Regards

Richard

Hi Richard

Just looking at your ferrite on the battery temperature lead and noticed that you haven't looped the lead round the ferrite.
Is it ok like this in this case?

Ian,

I'd tend to agree with you but the SMA manual shows them used like this. In the case of the ferrite for the earth leads there is no way you could do this anyway. I was all on to get the earth lead from the 10mm2 T&E through one as well as the additional 10mm2 earth I've run as per SMA guidance.

As I write this that's the CU wired up including the connection for the Sunny Island 4.4M-12.

I'm in having a beer and sorting out something for dinner now before going back out and hopefully getting the battery side of things hooked up and commissioned/ operating before tomorrow.  fingers crossed!

Regards

Richard

Mike,

You've certainly got a shed load more capacitors on a larger PCB in the upper part, I haven't looked to see if the semiconductors are SCR/ thyristors etc..

I never fail to be amazed when I look at modern electronics, I look at the multi-pin SMD IC's and wonder how reflow soldering works so consistently on such a scale.

I did notice that Nowtys one was the same so reckoned that was the case.
Yes, get it finished tonight so you can store away tomorrows electrons for later use.

Good Morning All,

Well the SI 4.0M-12 has been commissioned (I think). Currently we're importing around 650W of energy from the grid and the SI is sat there with 86% SOC and not discharging anything.

I'll need to consult the Oracle (in the shape of nowty).

Regards

Richard

Good Morning All,

Well the SI 4.4M-12 hasn't blown up or gone into meltdown overnight but still doesn't seem to have discharged at all. I'll have to get back to the manuals and await guidance from nowty.

I've attached some photo's. The CU is now fully wired up, well until something else comes along although I have got to move the double socket and get it wired in. I need to secure the slightly long tails and earth to the fuse though. The 'dangly' 2.5mm2 T&E and the earth cable to the left of the picture (going top to bottom) are the generator output and extra earth lead (the latter going out to a grounding rod). I've used 'proper' cable glands throughout including the incomer tails. Why aren't glands with inserts shaped for T&E cable more widely available?

The extra enclosure which did have the Energy Meter has now been removed and the inverters go direct to the new CU, this cable has yet to be secured.

The wiring for the SI 4.4M-12 is done as far as the mains side is concerned.

As I said last night the battery packs are currently 'jury rigged'. The coiled grey cable is the ridiculously long Battery Temperature cable.

That's the swallows back yesterday morning and I saw a bat flitting around last night for the first time this year.

Regards

Richard
