Backup Power and Outage Resilience
Keeping critical loads alive through utility interruptions, sized by what has to stay running and for how long rather than by the size of the incoming supply.
What Goes Wrong At Each Stage And What We Do About It
- 1
Critical load definition
The problem. Backing up the whole building costs several times more than backing up what actually matters.
How we handle it. We start from the list of loads that must survive an outage and the hours they must survive it, then size from there.
- 2
Transfer design
The problem. Equipment that trips on transfer time defeats the purpose of the backup.
How we handle it. Inverter and battery are selected for the transfer behaviour the sensitive loads tolerate, and the changeover is tested at commissioning.
- 3
Battery selection
The problem. Backup duty and daily cycling duty wear a battery differently.
How we handle it. LiFePO4 formats are matched to the duty - deep daily cycling, standby reserve, or both - and to the space the site actually has.
- 4
Integration
The problem. Battery and inverter from different brands frequently will not communicate.
How we handle it. We confirm the CAN or RS485 protocol against your specific inverter model before the order ships.
- 5
Service life
The problem. An untested backup system is discovered to be broken during the outage it was bought for.
How we handle it. Monitoring is configured at commissioning so state of charge and faults are visible before they matter.

View Product →Sites This Solution Is Built For
Homes and villas adding solar self-consumption and backup, where the installer needs a kit that works the same way on every job.
See the application →Telecom and Remote Off Grid SitesBase stations, monitoring installations and remote facilities where every site visit is expensive and the power system has to run unattended.
See the application →Commercial and Industrial SitesFactories, warehouses, cold stores and commercial campuses where the electricity bill is driven as much by demand charges as by consumption.
