Hi guys, 

Looking for reviews opinions on this unit as a back-up for 2 TVs, 2 laptops, a set of Led lights and the wifi routers. Currently running on a 12V 1000W Mecer inverter with a single 12V  100AH battery. System works well with the switch over and handles the load quite well except with the repeating load shedding and long load shedding it doesn't seem to last the full 2 hours. Option I have is to add another battery to the set-up (cost R 3500) OR change to this portable unit (Cost: R13500 for 1000w and R20k for the 2000W).

Does anyone have any experience with these units or have any advise on the way to go.

Appreciate in advance.

Don't know, but reading the specs..
 

Specifications;
-Net weight; 29.5kg
-AC Output power; 2000W
-USB-A Output [x3]; 5V-2.5A
-AC Output peak value; 300W
-Dimensions; l=278*445*662mm
-Battery power; 2048WH 25.6V
-USB-QC3.0 Output [x2]; 2A, 24W Max
-Type C Output [x1]; 3A, 60W Max
-Car charger output; 12.6DC, 8.5A, 107W Max
-Maximum power devices supported by peak value; 300W @200ms

300W max, I'd say give it a miss, way too much money for such a weedy affair...

@Kalahari MeerkatI think it is 3000w max for 200ms spike load, and 2000w through the AC.  I might be completely wrong on this. 

 

 

 

@JPNiemandThis gave the specs and other data., like 1000W, but 2000W rating and the 300W peak, based on that, I'd avoid this item, since the specs are dubious, but if you have one or get one, please report back some real world tests about what the peak power out is, if it is 300W, few fridges will start on this unit...

My Neighbor bought one, let me have a chat to him to understand how he is finding it, what he draws etc. @Kalahari Meerkat

If one reads the specs the peak is 3kw for 200msec. Not just 300W.

Refer to the pictures that were posted by OP.

I never trust anything where the specs are either missing, incorrect or ambiguous. 

I mean look at this, https://www.electromannsa.com/products/fivestar-portable-rechargeable-solar-backup-power-station

they call it an "MTTP" solar charge controller instead of an MPPT (although this may be electromann's mistake)

Thanks JP,

Will await your feedback.

 

My brother baught himself this one today - will provide feed back on it. But the specs seems decent and its a Mecer - at least you will get support form Mustek if it gives problems.

They also do a the 2000w unit

problem I see is "Mains charging current: 10A" which I'm guessing refers to the 24V battery side... this could take quite a while to recharge, which may not get you to 100% even remotely... but it obiously also depends on the current used, but 10A is effectively 250W, if your load is, lets say 400W over 4 hours, 1600W, it would already exceed the (24*50Ah) 1200-odd, really call it 1kWh (80% DOD) capacity of the battery and at 250W charge rate would take a looooong time to recharge... so specs not so great, I think, but if the consumption is only 150W times 4 hours, 600Wh, the 3 hours later (if you have 3 hours worth of power) the battery can be full again...

Thanks. This is one I am considering as well. The warranty is compelling.

Thats a good point, my consumption is a relatively low but with the way LS is at the moment, there is a high likelihood that there may be bouts of 4-6 hours followed by another in less than 6-8 hours which may not allow for enough recharging time. Beginning to think that without solar to augment re-charging it may be a bit of a waste.
