Hubble vs Freedomwon vs LBSA vs Pylon - which?


Recommended Posts

Posted

OK - so now I'm getting quotes for PV installs and can't compare the offers because of different battery makes. My daily consumption is below 20kWh at present.

Essentially I am looking at:

  • 8kW Sunkynk inverter
  • 10kwh battery
  • 8 x 540 kWp Panels = 4320kWp

The different offers come with very battery combinations, and I am hoping for advice on which are the batteries that give no problems:

  • Hubble - 2 x 5.5kWh
  • Freedomwon - 1 x 10/8
  • Freedomwon - 2 x 5/4
  • LBSA - 2 x 5.1kWh
  • Pylontech (waiting for the offer)

Which combination would be the best to go for, from a reliability perspective? I am looking for a set and forget system.

Thanks for your insights!

Using this criteria and not because I have nothing but the best experience with Pylontech since my first two batteries which were bought in August 2020. I would strongly urge you to go through this forum and you will be able to make up your mind. Search topics on all those batteries and your choice will be easy if reliability is what you are looking for 

If I were to do my install again, I would still go for Pylontechs

Note that some of the battery ratings are for marketing purposes and not real life.
Check with the supplier:
1) Actual usable kWh with a daily cycle (Eg. To prevent dendrite formations some batteries are limited lower than marketing capacity)
2) Warranty with daily cycle of 80% or 90% DoD - there is a big difference between 3000 (8 yrs) to 6000 (11 yrs)
3) How does the BMS count a cycle - some count discharge + charge as 2 cycles so 3000 cycles is ~4years.

Thank you for the tips! A very important difference between the different cycles! WOW!
Whilst batteries are a high cost, I believe that the technology development of batteries within the next 10 years will mean that if you need to replace batteries within say 5 years even, the size and capacity of batteries will change immensely! We may even end up with a totally different technology to store energy!

I thank you for your tips and your advice. Many thanks!
