Product Description

How can PEEK TO POWER help your work?


  • Full-scale monitoring of UPSs.
  • Real-time measurement data: voltages, wattages, battery voltages one-by-one.
  • Online analysis of measurement data.
  • Internet based mobile access.
  • Support financial planning of operations by forecasting operating costs.
  • Automatic service notification.
  • Unlimited number of type-independent devices in one system.

PEEK TO POWER is a trademark, representing a complex system of hardware and software components.

It allows you to monitor the status, operation level and technical parameters of your security power supply systems in several areas without the need for your onsite physical presence.

Its main advantages are that it can be used for equipment independent of type and it is able to integrate an unlimited number of devices - even installed in different locations – into a single system.

In most cases, security power supplies are deployed in rooms where operating staff and maintenance personnel are rarely present. From the point of view of safe operation permanent availability of relevant information whether the actual operation is under normal conditions or not is of great importance.

In the event of a malfunction or failure, immediate intervention of the operator is the most important issue. PEEK TO POWER provides great support to achieve this since it monitors the entire system in detail, analyzes measured data and reports abnormal status instantly on the web interface, by email and/or SMS depending on system set-up.

Hardware components of the system are as follows: measurements of each battery, voltage and electric power measurement of UPS inputs and outputs, UPS status display (by-pass mode and malfunction).

The software basic module, the maintenance module, and the battery run-time module maintain operational levels tailored to operators’ needs.

In what areas can the PEEK TO POWER system help your work?


  • It provides real online data on security power supply: voltage, power, status, errors, notifications.
  • The most important data of safety power source are available in one place.


  • Measures the condition of the batteries one by one, performs a comparative analysis, sends alerts of abnormal values and malfunctions.
  • Built-in trend measurement allows you to measure the discharge curve of batteries and this way the most accurate overview of battery conditions become available.


The type and device independent measuring system allows you to monitor the equipment’s own measurement data.

  • By means of the status indicator repair time is shortened in the event of a malfunction.
  • Recording the highest output power helps to find the power consumption peaks and possible faulty electric apparatuses.

Solar Panels

In solar applications, the system is able to identify faulty, weakened and contaminated solar panels and this feature makes easier to restore the entire system to its highest possible performance. Comparative analysis sends notification of failure(s) in time; thus power production loss can be minimized.
