Solution

Off-Grid & Weak-Grid

Standalone PV-plus-storage power for sites with no grid or an unreliable grid, with optional grid-forming control.

The challenge

Power where the grid can’t deliver

Remote sites, islanded operations and weak-grid locations need stable, lower-cost power without depending on an unreliable or absent grid.

  • No grid connection — or one so unstable that production and equipment are at risk.
  • Diesel-only supply is expensive, polluting and exposed to fuel logistics.
  • A standalone system has to form its own stable AC grid and run day and night.

How it works

How an off-grid system works

PV covers daytime load and charges the battery; grid-forming storage runs the site through the night.

  1. 01

    PV generation

    A PV array sized for daytime load and battery charging is the primary energy source.

  2. 02

    Grid-forming PCS

    The PCS forms a stable AC grid (voltage and frequency) for the whole site, with optional genset support.

  3. 03

    Battery storage

    Surplus PV is stored in LFP batteries to carry the site through the night and cloudy periods.

  4. 04

    24/7 supply

    Loads run on solar by day and stored energy by night — stable, lower-cost, independent power.

FAQ

Frequently asked

Can the system run fully off-grid?

Yes. Grid-forming PCS create a stable AC grid for the site, with PV and battery as the energy source and an optional genset for backup.

Does it work on a weak or unstable grid?

Yes. SAKETE has delivered PV-plus-storage to industrial sites on highly unstable grids (e.g. Kenya, Yemen), stabilising supply and shifting load to cheaper clean energy.

Can batteries be installed securely on remote sites?

Yes. Battery clusters can be installed indoors to protect them from theft and weather, as done on the Kenyan industrial-park project.
