Depth of discharge for a Multiplus ll GX 5kva
We have recently installed a Victron system but we would like the system only to use 40% of the battery capacity and to charge it using the grid, there are 2 X 4.8kwh pylontectech lithium batteries installed with 8 X 540W JA Solar panels with a 150/85 Mppt.2021-07-07 at 15.21.02.jpeg
Hi Paul B,
Here is a list of what is currently running from the system:
Inverter is a Multiplus ll GX with a venus GX controller built-in X 1
MPPT is a Smartsolar MPPT 150/85 X 1
Batteries are Pylontech UP5000 X 2
Panels are JA Solar 540W X 8
and I have attached all other necessary document, hoping this is what you are refering to.
Kind Regards
Piet Shabangu

Use Optimized (without BatteryLife) instead. It's the better choice when you have a LiFePO4 battery.
Why you enabled AC coupled PV feed in when you don't have a PV inverter?
Do you actually have an Energy Meter?
In that case you have wrong settings.
In ESS change "Grid metering" from "External meter" to "Inverter/charger".
And in "Grid feed in" disable "AC coupled PV feed in excess".
Take a read of the ESS manual and check all your settings.
Hi @Seb71 One last Q in this case the inverter is charging the batteries through the grid and the solar panels because the batteries % is below 60% but when it gets to 60% it will stop charging and start to use power from the solar panels and the batteries I just want to make sure I understand it correctly.?
If using "Optimized (without BatteryLife)", as long as the battery is above the "Minimum SOC" level, the Multiplus inverter should not charge the battery with energy from the grid (if set properly, the low battery voltages should correspond to a SOC lower than "Minimum SOC").
The system is on "on mode".

In the ess section you have allready set the grid set point to 50
then further down there is scheduled charging so setup some schedule charging to the levels you want and times you want them to occur
once you set these you should get what you want I think
