    I'm selling the Freedomwon battery. This was first installed on the 05/08/2022, removed from the system on the 08/06/2026 The battery is in good condition, you can be provided with the details of the installer details. Credible installer that I have been used from back in 2022. You can make an offer, but not less than R15 000.

    I had some grandiose ideas of setting up a parallel config - but been struggling to find a mate for this one that I bought on the used market. Changing plans. LuxPower LXP 5k - with Wifi Dongle. True Hybrid - ability to blend PV, Battery and Solar. This is not the SNA version. Features comparable to Solis, Deye, Sunsynk etc. Not that I need to explain to this audience 😁 It's missing the mounting bracket - but a plan can be easily made I reckon. R6000 Based in Cape Town. More than welcome to pop by and we can hook up a battery and test.

  10. Currently selling my current Freedom Won 10/8 battery to update to more kWh battery system. Purchased a house with the PV system installed which was December 2025. Current new 10/8 batteries are about R40 000, I am looking at +-R23 000 due to little cycles the battery has gone through. Based in Blairgowrie.

  25. Started by RenierN,

    I have two Bluenova BN52V-100-5.2k DU batteries I need to sell. After replacing my previous inverter with a Solis S6-EH1P8K-L-PRO, I found it is not compatible with the Bluenova batteries. After some research and support emails to both Solis and Bluenova, it seems better to replace them. I want R20k each. 22 Months old. If anybody is interested, Cape Town based.
