UPS

UPS (Uninterruptible Power Supply) devices protect your equipment against power cuts, power surges, undervoltage, voltage spikes and lightning strikes. In the event of a power cut, the UPS switches to a backup battery to keep your devices powered up and prevent data loss or damage to sensitive equipment.

There are two main types: online UPS units, which are connected in series and continuously regulate voltage, and line-interactive UPS units, which are connected in parallel and controlled by a microprocessor to monitor and correct voltage.

For solar requirements (DC/AC conversion and autonomous power supply), and for storage and backup mode, see the following links

230V converters
Hybrid inverters

Choose in 30 seconds

  • Sensitive equipment (computers, networks, critical equipment): choose a suitable UPS with sufficient regulation and autonomy.
  • Technology: online = continuous regulation; line-interactive = monitoring/correction via microprocessor.
  • Autonomy: size according to the time required in the event of a power cut (minutes/hours) and the power of the devices.
  • Solar requirements (230V autonomy from battery/panels): consider 230V converters or hybrids.

FAQ - UPS

1. What is a UPS (backup power supply) used for? +
A UPS protects your devices against outages, overvoltage and spikes, and keeps power running for a while thanks to a battery.
2. What’s the difference between an online UPS and a line‑interactive UPS? +
An online UPS is connected in series and continuously regulates voltage. A line‑interactive UPS is connected in parallel and monitors/corrects voltage via a microprocessor.
3. How do I size the power rating of a UPS? +
Add up the power of the devices you want to protect (with headroom for peaks) and choose a model that matches your actual needs.
4. What runtime should I target during an outage? +
It depends on how long you need to keep working or properly shut down equipment. The longer you want to run, the larger the battery capacity must be.
5. Does a UPS replace a solar inverter? +
Not necessarily. For 230V autonomy from batteries/panels, look instead at 230V converters or hybrid inverters, depending on your configuration.
