Round-the-clock power for an industrial park on an unstable grid

The background

The customer runs an industrial park with high power consumption, served by a highly unstable local grid. Production needs stable, low-cost electricity around the clock, and the batteries had to be protected against theft.

The challenge

An unreliable grid and high day-and-night demand put production at risk — and the usual outdoor battery layout was a security concern.

• Frequent grid instability threatened continuous production.
• High electricity demand ran through both day and night, not just working hours.
• Batteries needed to be physically secure against theft.

The solution

A PV array sized for daytime load, paired with a secured indoor battery hall for night-time and outage cover.

SAKETE supplied 1,536 × 580 W PV modules to cover daytime demand, with ten 215 kWh battery clusters and the storage PCS sized for continuous park operation.

The battery clusters were installed indoors — a deliberate layout choice that protects the assets from theft and the elements while keeping cabling runs short to the PCS.

During the day the park runs on solar; stored energy carries the night and bridges grid interruptions, so the site no longer depends on an unreliable supply.
