Solax battery wanted

[Tarleton lad]

Hi, looking for a Solax, Gen2, 6.3kwh triple power battery. Solax have discontinued it despite telling us we could add extra batteries to our system as and when funds allowed. Refurbished or good used and can collect. As an alternative, do any of you technical boffins know if it would be possible to design a circuit board, retro kit that would add 500w to the new 5.8kwh battery and allow that to be connected to our existing 6.3kwh batteries.

What is the operating voltage of the 6.3 battery? Internet search suggests about 100V

The TP58 says

• Operating voltage range: 100 - 131V

The TP30 looks to be similar

Suggest contacting solax to see if these can be substituted for your 6.3?

a brief bit of googling finds these 6.3kWh, might be worth calling them to see if they still have stock
