Load
We total the consumption and add headroom: over the years batteries deliver less than the rating states.
Two figures are needed: how many watts to carry and how many minutes to last until a clean shutdown.
We total the consumption and add headroom: over the years batteries deliver less than the rating states.
Simple topology suffices for network hardware; servers need double conversion.
We link the power unit to the servers so that on discharge they shut down by themselves and in order.
Alerts about power loss, battery condition and an approaching replacement.
A split system sized by heat output with headroom for hot weeks.
Regular load testing and planned battery replacement before failure rather than after.
Selection and installation take one to two weeks; climate control depends on whether the room is ready.
We calculate consumption and heat from the ratings, then check against instruments.
Model, capacity, runtime, whether extra batteries are needed.
We install it, connect it, link it to the servers and test the shutdown.
A calendar of checks and replacements, alerts configured for the responsible people.
The only way to learn the state of the batteries is to load them. The indicator on the case shows charge, not remaining capacity: a unit can report full readiness and last forty seconds. A test once a year answers the question honestly.
Usually not. Servers need double conversion and reserve runtime, while network hardware is served by a simple unit. Splitting them is cheaper and safer: the failure of one supply does not black out everything at once.
Voltage sags are more dangerous than a full outage: the equipment does not switch off, but the power supplies wear themselves out. Here a stabiliser or a double-conversion unit helps, delivering steady voltage regardless of what happens on the input.
We judge by age and by test results. If runtime still falls short of the calculated figure after a battery change, the electronics are worn. That usually happens in the eighth to tenth year.
Send the equipment list for the server room. We will calculate power, runtime and cooling.
