Hi everyone,
How can my BMV700 show right battery % with a US3000 Pylontech battery?
The BMV700 is showing 100% charge although charger is still in Bulk and LEDs of the Pylontech is showing there are still charging....
I have the default charged voltage 52,8V (but shows battery 100% although voltage is under 52V) and default tail of 4%
Peukert's is on 1.05 and charge efficiency at 99% as recommended.
Thank you
afaik the Pylontech is reporting State of Charge to the GX device. There is no need for a BMV/SmartShunt. And even if you want an extra shunt, it would become almost impossible to sync it with the shunt of the Pylontech.
I agree with the above replies. what you may need though is the proper victron VeCan data cable specific for your pylontech model to the gx .
I don't have a gx. I have a multiplus 48 3000 with NO* com port to communicate with the battery and an mppt 150 35.
What Voltages correspond to what charge % of the battery by a 48V pylontech battery then?
Thank you
In contrast to lead acid, the voltage in a lithium system cannot be used to determine the state of charge. Impossible.
And I strongly suggest to include a GX device in your installation.
If it is the first time you power up the BMV it always will show 100% you have to make a full charge cycle to synchronize the BMV to 100%.
I'm not 100% sure but isn't the Pylontech shutting down after a few minutes if there is no Can.bus communication?!
I have this system running since 10 days now. Pylontech is not turning off without can bus communication...
Neither Pylontech BMS nor Victron Inverter doesn't show the time remaining unlike Smart Shunt does. Also, the deepest discharge Ah, etc. So there is still an added value but it's not critical.
Here is the difference Summary from Pylon and from the Victron Shunt. But for me personally Time to go matters.
