Weekend Installation - Guard Hut


Recommended Posts

Hi,

 

Thought I would share a picture of an installation I did over the weekend at a nature estate's guard hut.

The system functions purely as a UPS and has no solar panels connected to it.

 

Components used:

  • Axpert MKS 3kVA Plus 48V
  • 4x 12V 100Ah Lead Crystal Batteries
  • 1 x 100Ah knife fuse
  • 1 x 20A DP CB

The estate is situated about 15 km outside of Windhoek and experiences regular power outages. 

This installations serves as back-up for the guard house lights, electric fence, intercom system and gates.

 

I really love these Axpert inverters! Great specs, great price and very intuitive to use.

Can anybody from Windhoek help we with the  informations where to get mounting rails, batteries, etc...

Any help/info will be appreciated.

Hi CasualCheetah,

 

Nice installation.

 

I have a suggestion for you:

 

For a pure UPS system without Solar Panels you could have used:

Axpert MKS 3k-24 or

Axpert MKS 3k-48.

 

The only advantage that the "Plus" models offer, is an increased Solar Input Power Rating, which you don't need unless someone plans on adding solar panels to the guard house at a later stage.

 

Going with the non-"Plus" models would result in a saving in excess of R2000.

Approximately R8,390 vs R6,150 depending on your supplier.

 

Furthermore, I don't really see a technical reason which would justify going for the 48V over the 24V version in this case (ie. no Solar required). The AC charging power for both models are the same.

 

The 24V version will however require a larger battery fuse and thicker battery cables, so the price difference between the 24V and 48V version will probably not matter in the end.

 

I recently specified the Axpert MKS 3k-24 for a very similar setup to yours, ie. guard house with 2 fence energizers and 2 boom gates and a few lights, no solar panels.

Hi DrLoLCAt,

 

Thank you for the comment.

 

I am fully aware of everything you mentioned, but I got the inverter completely free. 

For that reason alone did I continue to use it for the installation. Also, there are talks about breaking down current guard house to build a larger/better one.

Should that happen, then solar will be integrated into the system. Customer wanted ability to add solar if they ever wish to do so.

 

The "plus" model therefore ticked a lot of boxes and also made the installation easily expandable should solar modules be added.

 

Thanks none the less :)

 

Cheers!

Hi ibiza,

 

There is a company called HopSol Africa situated in Whindhoek. You'd find everything you need from them.

 

Cheers
