So I'm ready to take the next step in my emancipation journey, and hoping to get some advice from peeps with similar setups.
My current usage, after replacing the main geyser with a solar geyser, averages around 25 KWh/day.

An installer recommended the following setup:

  • 12 * JA Solar 535 W - Mono-crystalline MBB Percium half cell SF QC4 connector
  • 5 Kw Hybrid Inverter ( Sunsynk 5KW) single phase
  • 1 * Pylontech US 3000c 3.5Kw


I'm considering an 8 Kw inverter though, and either

  • 3 * Pylon US3000C 3.5kWh Li-Ion Solar Battery
  • or 2 * Hubble Lithium AM-2 51V 5.5kWh100Ah
Based on my usage, should I get the 5Kw inverter, and upgrade later if required.

Or should I get the 8Kw?

Also, which combination of batteries would be best?

You can check out my recent install went live Sunday super happy!

Hi all, I am finally getting round to making this thread. After loads of research and another bout of load shedding I finally decided to pull the trigger and load shed Eskom. Prior to going solar I already had all the lights on LEDs, house is kitted with energy efficient appliances and...

I have your alternative consideration go with the 8kw now if you can afford it. Also super happy with my hubbles.

You need to figure out what you want as well because that installer recommendation on the battery side wont get you very far at all. remember the pylontechs are 0.5c so you will only get 1.75kw out that battery

Hubble over Pylon
 
I like your installer for quoting sunsynk then I saw 1 x pylontech. What a dumbass. 1 x am-2 would work though.
 
Apart from usage you need to think about whether you want to split your board into essential or not. We went for the larger inverter and more batteries and everything on the inverter so that we can make the call on where and when we want to run everything in the house should we want to. This is the more expensive route but has made the wife and me happy for the flexibility it provides. Was more expensive though

Why? It's still a 48V? And some can even work without a battery so he can install the solar and whatever battery he has and add a bigger battery later.

2 hubbles for the 8kW
1 hubble for the 5kW

Either PM me or write here your nearest shopping center or landmark a few km from where you live. I wrote a program for my thesis to pull satellite imagery from nasa to calculate incidence normalised cloud cover. I can work out exactly your average daily hours of power generation equivalent for every month of the year

That way we can work out exactly how big you need to be on the collection side to cover every month

Thanks. My daily usage is double yours, so seems like 8Kw would be better suited.

Sure. We can use Hoerskool Florida as a landmark.

Before installing the solar geyser, average monthly usage was around 950. Current average daily usage has now dropped to +- 25KWh.

Ah, I see it now. :cool:
8K for sure, or even 2x 5K in parallel.

If possible pick a spot where you can add a third or fourth battery and tell the installer to leave space.

I recall reading somewhere that you can't mix old and new batteries. Does this not apply to the Hubbles?

Mmm, I'm still pretty new to all this. I think it would be fine with the hubbles but I'm sure someone else can confirm.
