How We Set Up Our Home Appliances to Live Completely Off-Grid

Going off-grid does not mean giving up appliances — it means scheduling them intelligently. This article documents the exact appliance setup in our KZN home: gas geyser replacing the electric, washing machine and tumble dryer running during peak solar hours, pool pump on solar-only timing, and a borehole pressure pump on demand. Backed by real telemetry showing the highest consumption reading across 8 days was 2,631W — just 53% of the inverter capacity.

What It Really Cost Me to Go Off-Grid in South Africa

Going off-grid is not simply buying an inverter, a battery and some panels. After transitioning my home completely off-grid following an Eskom disconnection, I documented every cost — including structural work, battery compatibility failures, and the hidden expenses that most solar ROI calculators systematically ignore. Total investment: ~R141,320.

My First Week Completely Off-Grid: Real Solar Performance Data From South Africa

Eight consecutive days of real SolarmanPV telemetry data from a fully off-grid home in KwaZulu-Natal, running through a South African winter on a shaded forested property. Grid power purchased across all 8 days: 0.00W. Overnight battery floor: 22% SoC. Peak production: 3,794W. The data, the BMS anomaly on day two, and what it all means.

How an Eskom Billing Dispute Forced Me Completely Off-Grid

This article documents how an Eskom billing dispute, driven by mismatched meter readings, estimated invoices, and unresolved account discrepancies, escalated into a full electricity disconnection. While attempting to resolve the issue through formal communication and evidence submission, the supply was cut despite the dispute remaining active. In response, the author accelerated a planned solar transition and progressively expanded an existing hybrid system into a fully off-grid setup. Built over time on a shaded, forested property in South Africa, the system required significant structural modifications, additional solar capacity, and a major battery upgrade to achieve full independence. The result is a real-world case study of energy resilience under non-ideal conditions, highlighting both the technical and financial realities of going off-grid. The experience reframes solar not just as backup power, but as a pathway to reducing long-term vulnerability to utility instability.
