Hi a farming friend of mine whose farm is dependant on a Lister generator is looking to install  a small PV system that would run a TV, couple of lights and cell charger. He is expecting his Australian family over Xmas and wants to make things a little more comfortable.

 

In 2016 he is looking to install a Axpert 4kW system and move the small temporary system over to his stockman's cottage.

 

Any ideas suggestions?

 

My system:

Axpert 3Kva (1Kva sufficient)

2 x 105Ah batteries

2 x 255W PV panels

 

Load @ 200W (TV, Amp, Decoder and a few lights) for 5 hours = 1Kwh

If it is an issue of cost, I still think you could get away cheaper say with a 1kva Axpert, than a say a seperate solar controller + inverter combination.

rather ask the Australian family to bring a SB Pro back for you....its the best Ausie unit out there

Hi All

 

I also think :  1.5Kw Pure sine Inverter

                     4 x 150W Panels

                     2 x 200 a/h Gel Batteries

                     1 x 30A 12V Controller

 

This should be sufficient for what you are looking for. Roughly R26k

Thanks Stephen

 

That is a good start.

Cost me R13K

I have been reviewing his system and the the largest draw in his home is a microwave of 900W. So instead of a 5kVA Axpert a 3KVA will probably suffice.

 

Based on that I would advise him to install a 3kVA as it is going to be mounted permanently and the is not much difference between the 3kVA and 1kVA. and then have 2 panels and 2 batteries 105Ah would probably be fine. My one hassle is that if I remember correctly the 3kVA can only handle 600W or 900W of panels. I suppose one could have a 2nd string of panels running through a Outback or something like that if he found that he needed more than 900W. 

I have been reviewing his system and the the largest draw in his home is a microwave of 900W.

 

Just keep in mind that a microwave oven with output of 900W probably consumes more like 1200W.

I see the newer spec is 1500W so more than enough for his application.

I have the 3kVA plus. And it can take 1500w of solar. Try and get the plus rather
