Hi All,
First off, incredibly sorry if this is very off topic post or not the type of system to talk about here.
I recently started watching Will and he has now given me an itch that wont stop.
I live in the UK and where i currently live, solar is not really a viable option and power costs are not horribly high.
I am a bit of a tech head and for work i run a full server cabinet at home for various bits and pieces
My servers currently runs off a very expensive APC SMX1500RMI2U, it is a great little unit for battery backup and power cuts are few and far between
The longest power cut in the last 2 years was 2 hours so nothing over the top
I work from home so server downtime is money lost which is the reason for me wanting something a little bigger and i am always worried about warranty on units
The downside of the APC is that for the fairly high cost, i get roughly 40 minutes of runtime out of it when the server is idle and when using it, id be lucky to get 30
I can expand it to roughly 2 hours for a reasonable cost with a battery module but the unit is around 5 years old now, out of warranty, and its time to see if a viable alternative is available should it fail besides just looking for another generic computer grade UPS
So, now the back story is done, i got the idea from Will to look at build a DIY Powerwall that is primarily just a large glorified UPS for my server but that could move with me in the future where Solar may be more viable. For now, I have no need to do anything else besides to store power for in the event of power failure
My primary objectives are:
My initial system idea was to run something like the following:
The above setup covers everything i need really except the switchover time.
The apc is listed at 6ms, with the victron being up to 20ms (presumably at 50Hz), some other units offer 10ms listed times but their ones i have never heard of
Some other more reputable companies such as SMA or Growatt seem to offer similar systems but of course are primarily designed around solar only so i'm unsure what they offer similar
So in short, is this a viable solution at all (has anyone done anything similar?) or should i stick to running normal computer grade UPS systems and ignore this entirely?
I'm in need of a new hobby so this has given me something to look at for a while and its not something i am looking to purchase anytime soon, but i am also happy to take the hint if i am over my head and coming up with solutions that are far too convoluted or over the top for my use case (a generator is not an option for example)
Regards,
Jamie

For now, I have no need to do anything else besides to store power for in the event of power failure
My primary objectives are:
- Last at least 2 hours with a 400w load
- A roughly similar price to the APC unit and a battery expansion
- Provide a better warranty period if possible
- Not take up a huge amount of space as the existing units sits in a server cab at the bottom
- Have a fast enough switch over time to keep everything on (the part i am struggling with most)
My initial system idea was to run something like the following:
- VICTRON MULTIPLUS 48/3000-35-50
- Pylon Tech US2000 (expandable in the future)
