Solar and LiFePO4 storage deliver savings beyond the meter — protecting sensitive equipment and production continuity.
Colour Magic Printers is a commercial printing operation with a sophisticated and energy-intensive production environment. Large-format printers, digital print engines, binding machinery, cutting equipment, and climate control systems combine to produce a significant and continuous electrical load. When Colour Magic made the decision to invest in solar PV and lithium iron phosphate battery storage, the primary objective was clear: reduce the escalating cost of electricity, which had become a material drag on production cost competitiveness.
The Unexpected Dividend - Equipment Protection: What Colour Magic discovered post-implementation was a benefit that had never featured in the original investment case, yet which proved to be one of the most financially significant outcomes of the project. Commercial printing equipment particularly modern digital press platforms contains highly sensitive electronic control boards, servo drives, and precision electronic components that are acutely vulnerable to the power quality disturbances that characterise South Africa's grid supply. Load shedding events involve abrupt disconnections and reconnections. Generator switching introduces voltage transients. And even during normal grid supply, voltage fluctuations, harmonic distortion, and micro-interruptions occur routinely each one representing a stress event for sensitive printed circuit boards.
Prior to the SolarEPC installation, Colour Magic was experiencing a recurring pattern of PCB failures and electronic component damage that required expensive replacement parts, extended machine downtime, and production schedule disruptions. The cost of a single PCB replacement on a high-end digital press can run to tens of thousands of Rands. Multiply this across multiple machines and multiple incidents per year, and the cumulative cost is substantial and largely invisible in the operating accounts, buried under maintenance and repairs rather than attributed to power quality.
The Power Quality Solution: By installing a lithium iron phosphate BESS in conjunction with high-quality electronic inverters, SolarEPC effectively decoupled Colour Magic's production equipment from the grid. The facility's sensitive machinery now runs on clean, stable, inverter-conditioned power at all times free from the voltage spikes, sags, and switching transients of direct grid supply. The result has been a dramatic reduction in PCB failures and electronic component damage, delivering savings in maintenance and replacement costs that, in the first year alone, materially accelerated the project's payback period beyond what had been projected in the original business case.
Colour Magic's experience is a compelling case study not only for the printing industry, but for any manufacturing or production environment that relies on sensitive electronic equipment. The dual benefit of reduced energy costs and dramatically improved power quality makes the SolarEPC solution an investment that pays back faster than the numbers on the energy savings alone would suggest.
