The 6kWh battery is a few months old, the 4.5kWh battery is 3 years old and may have a different number of cells so the votage would differ
They will be close together.
If the voltages match then is this connection after the two BMS boxes?
If the voltages are different I suppose this is a no-no.
Both batteries are Solax "Triple Power". The 6kWh one is a few months old. The 4.5kWh one is some 3 years old.
They may have different number of cells so may be different voltage.
If the voltage is the same and I connect them in parallel is that AFter the two BMS boxes?
If the voltages differ...
Both batteries are Solax "Triple Power"£ of different ages, see my reply above.
I looked at spec for the Solax parallel box but it requires the age diffenmce to be less than 3 months so no good for me.
The solar controller and inverter is Solar Edge 3680H
The 6kWh battery installed is Solax "Triple Power" HV10230 with BMS MC0600
The battery charger/Inverter is Solax X1-AC3.6
The battery that I have already and want to add to the system is Solax "Triple Power" T45 HV10040 with BMS MC0500

I have a 4.5kW solar panel array with inverter by Solar Edge.
Also I have a Solax 6kWh battery with BMS and Solax 3.68kW inverter in use.
I wish to add a second battery of 4.5kWh which has its own BMS.
How should this connect to the existing Solax inverter or do I need a third inverter ?
If I...
I have an ongrid system including Solaredge panels and inverter with a retro fitted Solax battery and inverter.
How does the system decide if the house load is powered from public mains or the battery inverter or the solar panels' own inverter?
Do I have any control over this?
How can I measure...
