Hybrid Site Power

Solar leads, diesel fills the gaps

Every liter of diesel a remote site burns is a logistics chain. FIBER OCEAN blends solar, battery, generator and whatever grid exists onto one DC bus, engineered so the sun does the day shift, the battery does the transitions, and the genset runs only when it must.

The solution

One bus, four sources

A hybrid site is an energy dispatch problem solved in hardware. We engineer the four sources onto one bus, from our own lines, sized per site.

Solar leads

The array takes the day shift through solar-compatible charging at a flexible 10–50 A, built into the plant, not bolted on.

🔋

The battery floats

LiFePO4 floats on the bus, buffers the load and takes over with zero transfer time when the grid drops.

Diesel fills

The genset becomes the backup’s backup: fewer run-hours, fewer fuel convoys, lower OPEX at every remote site.

🗺

The bus decides

Rectifiers at ≥96% efficiency and the site controller arbitrate sources on one −48 V bus, reporting every decision upstream.

Anatomy of a FIBER OCEAN hybrid site

Eight layers on one bus. Every numbered element is a FIBER OCEAN line, engineered together so the dispatch order is physics, not luck.

Anatomy of a FIBER OCEAN hybrid site: solar array, hybrid DC power cabinet with rectifier slots, floating battery cabinet, silent generator canopy with fuel tank, containerized battery storage, weatherized cabinets, camera post and the grid line arriving on a pole, around a telecom tower, with numbered callouts matching the table below

Site scenarios

Four grids, one discipline

The same bus, weighted for the grid each site actually has.

No grid

The off-grid tower

Solar leads, the battery carries the transitions, diesel fills the gaps: the site stays on air with the fewest run-hours the sun allows.

Bad grid

The poor-grid site

Unstable mains become just another source: the battery takes over with zero transfer time and the bus rides through every brownout.

Diesel today

The retrofit

An existing genset site gains solar and a floating battery: the genset drops from prime mover to filler, and the fuel bill follows.

Fleet program

The hybrid rollout

One engineered site design replicated across the estate, with every site’s fuel, energy and alarms reporting to one center.

Why hybrids hold

Run-hours are the metric

The details that turn an energy mix into an OPEX line you can defend.

One bus, not four vendors

Grid, genset, solar and battery meet in one hybrid DC cabinet with MPPT solar charging, engineered as a system instead of negotiated at the terminal block.

Solar built into the plant

10–50 A solar-compatible charging is native to the hybrid range, so the array is a source, not an accessory.

🔋

A battery that never blinks

The outdoor lithium string floats on the bus and takes over with zero transfer time on grid loss, 2000 cycles at 80% DOD deep.

Hot-swap to the module

RM4850 / RM4875 rectifiers and the MCU-SM32Z controller are interchangeable with the indoor range; fanless DC Lite modules cover pole and rooftop sites.

🏜

Housed for the desert

IP65 outdoor cabinets built for power and solar equipment, rated for −40 to +65 °C service, covering hot outdoor areas of 55 °C and above, plinths included.

📊

Fuel is telemetry

Tank level, mains state and genset runs stream from every site; year-on-year energy ratios make the diesel savings auditable.
