We would like to add additional batteries to our existing off-grid solution, but the batteries we already have aren't being sold anymore so I can't expand the existing setup. As these are 4 years old at the moment, they've got plenty of life left so I would prefer not to replace the whole battery pack, rather to add to it with more batteries.
Is it possible to add additional batteries to the existing solution? Perhaps with an additional BMS or something? Thinking of a BYD LVS addition to the solution if possible.
Current setup:
- 9.5kw of panels
- BYD B-Box Pro 2.5-10 batteries (6 x 2.5kWh across 2 cabinets)
- BYD BMS
- Venus GX
- Quattro 48/10000/140-2x100
- SmartSolar Charger MPPT 250/85 rev2
- Fronius PV Inverter
