The Battery Thread (Solar / Inverter)

[ADrunkTeddyBear]

Installer prefers the Pylons, so I'll rely on his expertise. (He does install Freedom Won, Hubble and Pylontech btw)

All 3 of those are great batteries. They will never give you any issues and they have a strong local presence in terms or warranties

Does anyone perhaps have the Mecer Axpert 3000w (24v) settings that I need to use for my Hubble S-120's.

The Hubble website lists 48v settings so I don't want to divide by 2 in case it's incorrect.

Excited to try these out, only problem is weight 57kg, can hardly move them lol

These are the settings you can use

Bulk charge 28.8V
Float 28V
Cut off 22.4V ( can be dropped lower)

Thank you, what is your setting for option 13 (voltage point back to battery)

I think the default setting you would have is FUL but can be set to 27V, This function is more for an SBU setting to have it stop using the grid and switch back to battery mode

^ 27V is the default value

Thank you for the help, is really appreciated.

Indeed it is sorry brain is a little fuzzy after sitting 3 hours on a call with an installer trying to get rid of a Silly 72 error code on Parallel.

• Even if you cycle everyday, how do you use 20,520kW over 5 years?

I was referring to stored power. Give us your total battery discharge stats.

I'll probably do 10MWh in 5 years. Maybe slightly more now with the additional battery added today.

Only 1Mwh, I've been kinda lazy switching to battery. I'm too embarrassed to show my purchase power

Making the most of the spinning meter I have.

Still putting in slightly more than in taking from the grid.

In summer I'm putting in a third more. From next month I'll be taking more from the grid than putting back.

Point taken, hubble does not guarantee 16500kWh per battery. My rudimentary mathematics suggests that cells that degrade due to calendar aging and the effects of charge cycles are unlikely to lead to 3000*5.5=16500. The cycle life chart for the BYD cells suggests 80% remaining capacity by roughly 3000 cycles. The claimed reserve capacity could help. As said this is not tested yet.

Reason why I asked about hubble stating an energy number is because that is for me the most unambiguous way to state what is to be expected from a battery - so that would have been a very welcome change had they stated that.

Actually, you are correct, it is kWh, and yes, there would be degradation. We also don't know if it's linear or not. I just did a simple calculation, based on what we do know.
I don't know any manufacturer that would state it like that, but it is basically what the warranty states. And even 80% capacity isn't too shabby.

I have the hubble degradation chart. Have a look. Doesnt look too bad for a battery that can take so much beating over 10 years

Yes, it's great, especially at 1C and 35 degrees.
