Mecer 1440watt inverter with 2x100ah, can have installed for R7700 at your place, just pm me :)

Mecer runs near quite on 10ah charging, no inverter runs quiter than the mecer.

Nice ad pitch, but the ecco 1500w runs the same and the fans only kick in every 10m while on battery and charging not all the time, not the 2000w though that's a noisy beast.

I replaced my old Mecer system with this yesterday -

View attachment 1238314 View attachment 1238316

RCT-AXPERT VM3 5KVA - R 9K

RCT BAT DYNESS B3 - R 16K

Including VAT - 28,5k - excluding electricians fees.

Eskom makes us poor and electricians rich.


( I bought my first house for the cost of two of these batteries... )

The battery doesn't need some enclosure?

Looks like an easy plug&play setup except for the inverter part.

Hi All,
I would like to say thank you to all for the great feedback.
Sorry that I have not responded, work is hectic and load shedding hit again from 10am to 12:30.

I think I may go with the option @Cacti suggested but with lithium batteries, this will be used for my computer room.
Hoping it can run a high end gaming PC (but wont game during load shedding), will use it for work running outlook, teams and Remote Desktop) with 3 monitors connected.
1x Asus RT-AX88U Router
1x Fibre ONT
If powerful enough

I'll also purchase the same with normal batteries for my lounge to run My TV, NVIDIA Shield Device and Hi-Fi System.
Cacti Suggested this:

2400VA Mecer Inverter + 2x 100AH Batteries Trolley (8 HOUR BATTERY LIFE) KIT - 1440W (150-200 cycles) - GeeWiz

2400VA Mecer Inverter + 2x 100AH Batteries Trolley (8 HOUR BATTERY LIFE) KIT - 1440W (150-200 cycles) for sale online at the Best Prices! Door to Door and Overnight Delivery
www.geewiz.co.za www.geewiz.co.za
Will request the LITHIUM Deep Cycle battery x2 (250 battery cycles to 2000+ cycles) for the one unit.
I see it is on wheels so I can just move it to where I need it.
Hoping its basically plug and play to setup

Living in an estate makes things harder, I am in a sectional title 2 unit house, I could maybe invest in solar at some point.

So many options, i'm just looking fro simplicity :)

Thanks to all that did respond appreciate your time and knowledge:thumbsup::thumbsup::thumbsup:.

I'm a bit late to the party here, but this is what I run:

For my network devices:

shop.dbg.co.za

UltraLAN Micro UPS 60W DC and PoE Output (MUPS60W17.6AH)

UltraLAN Micro UPS (DC-to-DC 60W) with PoE OutputThe UlraLAN Micro UPS series delivers clean, automatic, reliable, constant power to small DC devices during power outages or where grid power is not available.The UltraLAN MUPS60W17.6AHis a compact DC-to-DC micro UPS with PoE and DC output...
shop.dbg.co.za shop.dbg.co.za

R1300 with all the cables

For my gaming PC (ryzen 3600, rx 5700 16 gigs of ram, 1 tb ssd 2 tb mechanical hd etc):

Takealot

www.takealot.com

Will power my PC playing games almost 4 hours, with 6-8 hours of juice just doing regular PC usage. I got mine almost a year ago for R20k. I've seen Flexopower run discounts on these semi-regularly so you can get it for about that price, but at the moment they're high in demand because of load shedding.

In total about R21,500, which is a decent chunk of cash towards solar, but my brother didn't want to start getting solar a year ago (live in his house) so this is what I came up with so I can carry on happily even when the power is out.

You need to take care of the batteries, else it won't last! Lead Acid does not like to be drained. You can upgrade the above to a lithium battery, which will push it up to 17k.

I've been seeing some sweet deals on 100ah LIPO batteries on Alibaba... Too bad I'm too chicken s**t to take the risk to buy batteries from there.
Hopefully they can get a lot cheaper, real soon.

Who decided that black, grey or beige were less acceptable than lime green ?

Bought a gizzu thingy to back up my router. Can last a whole day in the office with that and a decent laptop.
Otherwise a quality trolley with a some quality batteries if you need a step up in juice.

You need an inverter, not a UPS.

Preferably a low frequency inverter (i.e toroid transformer based), not the high switching crap 99% of inverters tend to be, especially if you intend to wire it into your house. (hint - if the inverter weighs less than 25 kg for 3kW, it is not a low frequency inverter)

You also need to bite the bullet and get lithium iron batteries for it (Iron, not ion. LiFePo cells are what you want)

You're looking at ~R11k for the inverter, and at 24V 100Ah ~ R9000 for the batteries (i.e. 2.4 kWh storage)

Most people can get by with a properly sized HF, if you're running very high surge devices like lots of pumps or big shop tools, which the OP is likely not doing, a LF inverter would be the way to go.

HF however dominates in residential application when wired into DBs, for good reason.

Modern HF inverters have become more efficient than their LF counterparts at a significantly lower price point. Their are lots of HF inverters on the market that can give twice their rated output for 10s, which in close to LF territory and more than sufficient time for devices that require a large start up power.

Just like you get HF crap, you get LF crap as well.
