- [How a Battery Energy Storage System Works, and How to Design One That Holds Up](https://technocontrolcorp.com/blog/how-battery-energy-storage-systems-work-and-how-to-design-one): A battery energy storage system works by moving DC energy from cells through modules, racks, a Battery Management System, a Power Conversion System, and an Energy Management System that coordinates charge and discharge; designing one that holds up means matching power (kW), energy (kWh), C-rate, chemistry, and thermal management to the actual load profile, not a generic spec sheet.
- [Oil-Type vs Dry-Type Transformer: How to Choose the Right One](https://technocontrolcorp.com/blog/oil-type-vs-dry-type-transformer-how-to-choose): A dry type transformer is the right call anywhere fire code, indoor occupancy, or environmental permitting rule out liquid insulation, while an oil type transformer wins on efficiency, overload headroom, and footprint everywhere else. The decision comes down to matching the insulation and cooling method to the site's fire rating, ambient conditions, and loading profile, not to catalog price.
