Low-frequency pure sine wave inverters

The Ellies MP low-frequency Pure Sine Wave inverter range with built-in transfer switch  provides the same features as uninterruptible power supplies (UPSes). This means that, when there is a power failure, the inverter switches over to charged batteries automatically. Once the electricity supply is restored, the inverter synchronises to the incoming mains from the utility and then […]

Surge protection for data centres

There are two main types of risk in terms of data centres and electrical power surges: lightning strikes and switching surges caused by the switching of cooling systems’ inductive loads or possibly generators switching over from utility supply, and causes stemming from the power utility. Ideally, the most comprehensive surge protection solution would include all […]

Battery energy storage technologies for off-grid and transport applications

Energy storage systems play a crucial role in off-grid applications globally. Although various energy storage systems exist, this article considers different battery technologies for their suitability for off-grid and electric vehicle applications. Off-grid electricity can be defined as a stand-alone power system or mini-grid to typically provide a small community with electricity without the support […]
