Battery backup systems for uninterrupted energy
Power outages can cause financial losses, equipment failures and critical process downtime. Battery backup systems keep your power supply active automatically, ensuring continuity in homes, businesses and industrial facilities.
At Bexie Energy we design custom backup energy solutions that combine batteries, inverters and advanced technologies to deliver uninterrupted power in any situation.
When the grid fails,
your power
doesn't have to
No more blackouts — uninterrupted power, guaranteed
A backup system detects the outage in milliseconds and switches on the batteries automatically. Your home or business keeps running — without you even noticing.

Types of battery backup systems
Choose based on your runtime, power and budget needs.
Battery storage systems
Store solar or grid energy and release it automatically when an outage is detected. The cleanest, quietest solution — no fuel, no noise.
Residential · CommercialHybrid inverters with backup
Manage solar, batteries and grid simultaneously. The most complete system: produces, stores and protects from a single unit.
Residential · IndustrialUPS systems
Instant switchover for critical equipment: servers, industrial machinery, security systems. So fast that connected devices never notice.
Industrial · DataAll-in-one solutions
Inverter + battery + management in a single compact unit. Installed in a day, minimal footprint. Ideal for retrofits and new builds.
Residential · Easy installWho needs battery backup?
From homes to mission-critical industrial facilities. If electricity is essential to you, you need backup.
Businesses with critical processes
Downtime can cost thousands of euros per hour. Factories, logistics, hospitality — battery backup pays for itself the first time it prevents an outage.
Highest ROIRemote installations
Rural areas or sites with unstable grid supply. Continuous power, no matter what happens outside.
Clinics and essential services
Medical equipment, alarms and security systems that simply cannot fail under any circumstance.
Homes with solar self-consumption
Add a battery to your installation and gain full autonomy — at night and during blackouts.
Data centres
Switchover in under 20 ms. Zero data loss. Zero service interruptions.
Pair it with solar and forget the grid
The battery recharges automatically with energy from your panels during the day. No charging cost. No grid dependency.
You use what you need and the surplus is stored automatically.
You don't even notice. The system kicks in before any device shuts off.
Daytime solar powers your home or business while you sleep.
Battery status, solar production and consumption in real time, from your phone.
How the full system works

Benefits of installing a battery backup system
A backup system delivers a range of advantages, both financial and operational:
Complementary solutions to maximise your energy
A battery backup system reaches its full potential when combined with other energy solutions. Batteries store energy so you can use it when you need it most, and hybrid inverters optimise energy management to boost the overall efficiency of your installation.
Battery backup FAQs
The backup system kicks in automatically, keeping your power running without interruptions.
It depends on battery capacity and the installation's energy consumption. It can range from a few minutes to several hours.
Yes — it's one of the most efficient solutions. You can store solar energy and use it during outages or whenever you need it most.
In most cases, yes — especially in environments where a power outage means financial losses or operational risks.
