Ted Lassoes the Sun!

Sorry for late reply. You had mentioned it in the HA forum too and I setup an account that day (a month or so ago)

For comparison sake (all theoretical)

Its ok to compare them on a sunny day. The real truth will come out when you compare them on a cloudy day.
Built-in forecast will forecast a cloudy day as if its a sunny day, where solcast will show you a closer to correct lower value, as to what you will probably get in real world terms. So for forecasting, the built-in one is useless to me, where as solcast is worth gold if I need to save battery over night in case such as early morning loadshedding.

So since Hubble AM-2s are rarer to find than a hen's teeth currently:-

I am in two minds:-

1. Ask PFS to cancel the Hubble and I go for either a Pylontech (https://powerforum-store.co.za/coll.../pylon-up5000-4-8kwh-li-ion-solar-battery-48v) (yes 0.5C) <-- It was the dream battery since @AchmatK started his thread

2. Or what the thoughts on this? I saw this as the local ACDC today being sold for about R24.3K

You searched for BN52V-100-5.2 - BlueNova

www.bluenova.co.za www.bluenova.co.za

What stood out is 2C - it said 100Ah@2C , 5200Wh <-
10 Year warranty

I can buy one at ACDC right now which means I can start project but then I would be locked in to expanding system with them. Problem is while I think their smaller batteries are rated well - unsure of this one and if it works well with SunSynk. Will also check PowerForum later to see if anyone has posted anything about them

I wouldn't worry to much about that as capacity doesn't change much with load on LFP.

Bluenova is good and you supporting local.

How many AM2s were you getting? There is a chap on Powerforum selling 9.6kWh Dyness powerbox units

Ah ok... price might be an issue then

Would've made more sense if you were getting 2xHubbles

I was so desperate that I nearly had an order of 2 x US-3000Cs to buy to get me going. But my Hubble battery has been delivered - woohoo. So now, I hope that come next Monday, I can say I lassoing the Sun!

Work to be done this weekend:-
1. I will be removing the SONOFF R2's that have been smart monitoring/managing my geysers with a CBI Asture Isolater switches. So I will replace the isolater switch at the geysers with the smart version (means I don't need to touch my DB for them) May ask the sparky to do it, so I get the COC for it - but will get everything configured on ground for my home assistant setup.
2. Also replacing 2 plug points in the kitchen with CBI Smart Plugs. This is for my kettle area and the airfryer area. The idea being if we on solar/battery power, and there is not enough capacity, then they will be shutdown remotely.
3. Figuring out how to get Sunsynk integrated to Home Assistant so I can use all the magic together. I recall reading @SauRoNZA post on this , so will need to read that thread deeply. I recall possibly using Raspberry Pi's for faster realtime info. Thankfully, I have about 4-5 unused one lying around.
4. Using the old Sonoff R2s on some electric heaters to actively manage them.
5. Installing Shelly Power switches on Aircon plugs (I should have done this ages ago - my shelley's have been sitting in a cupboard for over a year!

The biggest job for the sparky I think over this weekend is going or next monday is going to be pulling in a new 60A cable from the existing DB to the garage where everything is being installed and then back there. The entire house is going to be 'essential' with Home Assistant turning of the high drawer stuff or preventing them from turning on.

I think it's time I also install a new DB board fascia in - will go find one this weekend. Mines still looks like it is from the 1980's.

You can spend lots of money on Solar Assistant and do it that way.

Or you can spend almost no money and buy some cables and run it directly into HA. Bought an ethernet extension cable from Takealot for like R100.

SolarAssistant

solar-assistant.io solar-assistant.io

Home Assistant

homeassistant.sbates.duckdns.org homeassistant.sbates.duckdns.org

(Only using Dev version for the Grid Connection Status output which isn't in the Main build yet) works a whole lot with essentials/non-essentials automatons than using voltage which is too variable.

Thanks for the summary! I am gonna be cheap I think ;)
 
Question for folks.

1. Is it is good idea to put surge protection on the incoming feed from Eskom? To Protect the Inverter.

I assume from the inverter side to house , everything is already clean (like a UPS) so hopefully no further surge protection required.

Most of my electronic devices already have a surge protected plug in any case which I wont' be disconnecting.

Let me know when you find one. Mine is from the 80s, and the previous owner's kids have their stickers all over it...

Nobody should be using invertebrates for power generation in any event.

I put surge protection on my incoming line. Not sure if it is strictly required, but seemed like the wise thing to do.

The Bluenova you will need is the DU version - daily use. If you can get it for R24.3k, it is a much better deal than the Pylon or Hubble (even if you could get the Hubble for 20k IMHO). You will also require a BMAC to interface the Sunsynk with the Bluenova.

Doesn’t really make sense to me to even bother.

It may even interfere with the inverter’s ability to detect the grid correctly, based on no logic of any kind but the fact the inverter was built to do exactly this job.

For now, since my Hubble is here I am going with that. The bluenova was my second choice and then pylontech. Couldn't find anybody that had the DU. I guess my searching was poor.
