How you can survive load-shedding

[PUP Backup]

Sort of related.

Just before I emigrated from SA, was sitting in my CEO's office, talking about my resignation and why I had chosen to leave. He was asking the usual, what can he do etc. Then the building got loadshedded.

His discussion on why I wanted to go and what can he do to keep me, pretty much ended.

And now you live in Austarlia with a grid tie solar system that you don't even know how it works and all you do is to check what your credits amount to when you receive your account?

I have the 3000VA variant (as part of a pure battery backup - no solar). So far so good, anything in particular you're trying to find out?

at the moment I have a 2000w mecer ups running my tv / media box / led lamp / fiber wifi stuff etc. and it works fine.
when the ups runs out I have 2 x 105amp Deep cycle batteries going through a 1000w sine wave inverter to the ups.

my ceiling leds run off another 1000w ups.

just looking for something more elegant and neater in appearances - less hassle with charging individual batteries etc.

You can probably just lose the UPS. Put the batteries in a battery box and affix the inverter to the top of the box like Geewiz does with their kits (the one I have: https://www.geewiz.co.za/long-run-u...ah-battery-8-hour-battery-life-kit-2400w.html)

Mine easily runs my PC & server setup, which consumes between 200-500W, for 2.5 hours of loadshedding (could probably do 3-4 hours until the battery gets below 50% but haven't tested).

looks better than my wire nest I have on the floor

I'll make a plan when I'm back in CT

One thing I have noticed is that the switchover time on these inverters is a bit too long for certain devices. I have a DAS/disk shelf that will lose power when the mains goes out so I use a small UPS for it as an intermediary. The device also refuses straight up to run on modified sine wave power, only works with pure sine.

 

[Steamy Tom]

anyone have one of these?

RTC AXPERT 5000VA

i have a mecer king but they are all voltronic inverters, why do you ask?

edit: i saw your question

are you not running line mode?

as for the power issue, i assume you are trying to charge the batteries with a generator?

 

[DrJohnZoidberg]

You mean online? Like always running through batteries? If so then no, that would be terrible as the fans would run constantly and it's right next to me in the room.

Not sure why you say that and no, not using a generator anywhere, just mains to charge.

 

[spiff]

@DrJohnZoidberg can it charge both batteries at the same time?

I dunno (what I know about electrical stuff is rudimentary), I would assume so :shrug:

so where is the modified sine wave power input coming from?

 

[DrJohnZoidberg]

Sorry I probably should have explained that better. I have two inverters, one is modified sine which I bought first and found out it didn't work with the DAS so I moved that one to the entertainment area and bought a pure sine one for the PC & server gear.
