Backup Generator
Discussion
Hi
Want to get a backup generator for a small office - something like this has caught the eye https://www.parkerbrand.co.uk/8-125-kva-portable-p...
I see it says not for digital equipment... is that them just covering themselves or will we really not be able to power computers with it? If so, are there any generators that can be used?
Many thanks

Why do you need a 7kW output system?Want to get a backup generator for a small office - something like this has caught the eye https://www.parkerbrand.co.uk/8-125-kva-portable-p...

It states not for digital equipment, probably because it has a cheaper modified sine wave inverter. You typically want a pure sine wave inverter for electronic equipment.
A good start is using laptops so your client machines aren't affected by power dropouts and can last hours on their own.
Then hang the rest (network kit/servers/etc) off one or more UPS so at least they might stay upright if the power goes and they'll be buffered from glitches on the raw supply. Exclude stuff you can live without like monitors.
Then work out how long you might need the generator to run for, big difference between a cheap one with a rough looking output that doesn't need many hours of runtime, and one you're expecting to hang your delicate systems off for ?? hours.

Need a pure sine wave generator for things like computers and LED lighting. Looking at double that cost or so for similar power, considerably more if you want it to be reliable for longer periods.
As said, a small UPS can keep internet/wifi going in a small office for a while so laptops, mobiles etc can keep connected. Beyond that it's what you need - printing? Door access? Phone system, servers? Fridge? Other machinery?
Even so, given 1kw output and 1000Wh is available for £500 or so now with the portable power stations one or two of those would be preferable - many also do power pass-through now so can act as a UPS too.

That generator linked is rebranded rubbish. Honda EU series are the default inverter/sine wave output generators. However advancements in powerbanks/UPS capacity have probably rendered them obsolete.
How much power do you need, how long for and how often?? If you're running servers & switches, they're going to need more planning than simply running a handful of laptops on the end of a broadband link.
If it's to just protect yourself from the occasional 'glitch', what about using a battery based UPS system?
Some pointers...

- Do you all use laptops? If so, they'll all have batteries anyway.
- What's the bare minimum you need? If it's to cover for a short outage, do you need monitors (assuming you're using laptops)?
- External broadband - Run this on a UPS.
- If you go for a generator, are you able to cope with an outage while switching over or do you need it to be uninterruptible (eg DRUPS)?

At which point just get a 15kWh battery and gateway. If it's to just protect yourself from the occasional 'glitch', what about using a battery based UPS system?
