How I'm Turning a R23,000 Sunk Cost Into a Secondary Solar System

Rather than selling a perfectly functional Volta 5kWh battery for R6,000 on the secondhand market, I am connecting it to a small Growatt inverter and panel array, then feeding the AC output into the Deye 5kW GEN port using the documented Micro Inv Input feature.

Why Energy Independence Changes the Power Dynamic

Energy independence is not just about keeping the lights on — it changes who controls whether the lights stay on. After going fully off-grid following an Eskom billing dispute, the relationship between this household and its electricity supply changed fundamentally. The coercive power of disconnection disappeared. Disputes became administrative. The difference between backup power and genuine independence, and why that distinction matters for every South African solar owner.
