Weak Grid / Off-grid Microgrid

Stable power supply in remote and weak-grid locations

Problem

Remote industrial sites, mining operations, and telecom stations face unreliable grid supply or no grid at all. Voltage fluctuations, frequency instability, and frequent outages disrupt operations and damage equipment.

Site Conditions

Weak grid with voltage/frequency instability
Remote location with no grid connection
Critical infrastructure requiring 24/7 power
Existing diesel generator as primary or backup source

PSN Solution

PSN Energy BESS forms the backbone of a microgrid system, providing voltage and frequency stabilization. Combined with PV and diesel, it creates a reliable hybrid power system that ensures continuous, stable power supply.

Operating Logic

Grid Available (Weak)

BESS stabilizes voltage and frequency, supplements grid during dips

Grid Failure

Instant islanding, BESS + diesel maintain power without interruption

Off-grid Mode

BESS forms grid, diesel and PV synchronize to BESS reference

Load Fluctuation

BESS absorbs transients, maintaining stable output

Key Benefits

Stable voltage and frequency for sensitive equipment

Reduced diesel runtime and fuel costs

Seamless grid-off-grid transition

Scalable from single site to multi-site deployment
