VA (grid connection)

A wall or roof panel with an insulating core (EPS, PU or rock wool) between two metal sheets. It blocks heat and noise and is quick to install.

Fibrous insulation for container walls and ceilings. It keeps the sun's heat out, so the room stays cooler and the AC uses less power.

The common way to state air-conditioner capacity in Indonesia (from the Dutch for horsepower). Roughly ½ PK ≈ 5,000 BTU/h, 1 PK ≈ 9,000 BTU/h and 2 PK ≈ 18,000 BTU/h.

British Thermal Units per hour — the measure of how much heat an air conditioner removes. The larger and hotter the room, the more BTU it needs.

Generator capacity in kilovolt-amperes (1 kVA = 1,000 VA). Choose a generator with a margin so it copes when the AC or a pump starts up.

Miniature Circuit Breaker — a safety switch that cuts the power automatically on overload or short circuit. Installed in the container's electrical panel.

A conductor that carries leakage current safely into the ground. Essential for containers because the whole body is conductive steel.
