START WITH THE CONSTRAINT

Four problems.
One engineering team.

Modern rural home powered by solar and battery storage01No grid available

Power an off-grid property

Complete solar, battery and backup power designed around real household demand.

Explore this solution → Rural self-build comparing mains connection with on-site power02Connection cost too high

Replace an expensive grid connection

Compare the DNO route with a complete independent power system you own.

Explore this solution → Farm and commercial site supported by solar and battery power03The grid is not big enough

Give the site more usable power

Battery, solar, generator and microgrid systems for farms and commercial growth.

Explore this solution → Pre-built inverter and battery power system04Trade installation

Have the system engineered and pre-built

You install it. Callidus designs, builds, programs, tests and supports it.

DISTRIBUTED MICROGRIDS

Build the first phase.
Expand the whole network.

Start with the capacity needed now, then add coordinated power banks, battery storage, solar and new site phases as buildings and demand increase.

Victron distributed microgrid phased expansion
Grid connected or off-gridUse the grid where available, or operate with solar, storage and generator support.
Add capacity in stagesExpand inverter power, battery storage and generation as each phase comes online.
Distributed site powerServe estates, farms, campuses, developments and geographically spread loads.
Designed for resilienceSectionalised architecture can reduce the effect of a fault in one part of the network.
