Hi,
After many weeks of back and forth reading and research, I've kinda decided on a Sunsynk 8Kw hybrid inverter for my future setup.
I had my heart set on the Freedom Won 10/8 battery. But this is already going to hurt me badly  so the extra cost is just not easily justifiable no matter how much I try.
Therefore I was considering Hubble, Sunsynk or maybe Pylontech. Not far less, but enough to make a difference I guess.
3 Questions....which battery would communicate and work best with the Sunsyk Inverter with least hassles and best installation?
Second, would I be best advised to go for a single +- 8Kw battery, or should I rather be looking at using 2 batteries, maybe 5Kw each?
Third....can someone advise if they were setting up this system, would you go for Canadian Solar panels, Cinco or JA...and I'm guessing Monocrystalline?
What other important hardware do I need to look at besides panels, inverter and batteries?

Thanks!

Welcome to the journey into the light 🙂

Hubble, Pylon ad Sunsynk don't make an 8kw battery - you would be able to get 5kw from all 3 and Sunsynk does also make a 10kw if i remember correctly. In terms of comms all 3 have decent comms capabilities with the SS inverter. Of the 3 only hubble is 1C so you would be able to get the full 5kw draw from it - the others are 0.5c which limits your draw to 2.5kw if you get only 1 of the 5k batteries. If you do get hubble make sure you get the new ones (LiFePO4) - the older ones (NMC) had some BMS issues that necessitated a trip back to the warehouse. Sunsynk batteries also increase the inverter warranty to 10yrs

In terms of panels there isn't much difference between those 3 - they are great quality

Edit: Other important hardware to consider:

1. Earth Neutral bonding relay 
2. Appropriate fuses / RCDs sized properly for the panels and battery
3. Ensure there is good wifi connection at the installation site so that you can manage settings remotely

Having recently gone through a similar exercise, the SunSynk spec seems to differ a bit among websites (resellers), but per the SunSynk website (which is also not quite up to date in many respects) the spec appears to be 0.5C as "standard / recommended" discharge, 1C "max continuous discharge", and 2C peak (for 2 mins).  

The sunsynk battery doubles your Sunsynk inverter warranty to 10 years (parts) (I think when deployed together), while the new hubble now has an unlimited cycle warranty, per their website.

You could consider the Greenrich 5kwh 1.5C battery, so with one battery you could have closer to full power output of 8kW available. Otherwise two 1C batteries like the Hubble.

My aim is to get close to the 8kW, which should take care of all my needs. I hear good things about Hubble, Pylon and Sunsynk. The Sunsynk 10kW battery is close to the price of the Freedom Won, so then I may as well go for the FW. Warranties are nice, but who knows what the Sunsynk warranty will be like in 6+ years.
2 x Hubbles isn't waaay cheaper than the one Freedom Won, but a few thou is money saved.
Does anyone have an opinion on whether they would rather go for one x Freedom Won 8/10 or 2 x Hubble 5.5's? Which will be more effective and give the best results?
@mzezman Thanks for the advice on other hardware.
I don't know much about Greenwich. Can't be as simple as one 5.5Kwh battery giving you decent 7+Kwh? What is the downside?

You're mixing the units of kWh and kW.

The storage capacity is around 5kWh - 5 units of power - so same as one Hubble, Sunsynk 5kWh or similar.

But it is advertised itself as a 1.5C that can deliver 150A, basically 7+kW of instantaneous power.

Some users on the forum could comment on their real-life experience with it, I don't know it first-hand. I'm just naming it a cost-sensitive option that could allow you to start out with almost a fully functional 8kW system, just with a small reserve, but to which you can add more battery capacity later if needed. Or you could run your loads mainly during the day on solar and just use the 5kWh to see you through 2 hours of loadshedding at a time.
