As jy Windows en 'n PC verkies (wat jy vir ander doeleindes ook kan gebruik) kan jy altyd kyk na iets soos die VivoMini - hulle gebruik ongeveer 7W as hulle idle.  Om inverters te monitor kwalifiseer basies as idle - daar is net nou en dan bietjie CPU activity.  Ek gebruik 'n UN42, dis 'n fantastiese stukkie ingenieursvernuf in 'n besonderse klein pakkie...

Agree. This is harsh
I am also looking for the downloads and now I need to post 15 posts.
So this is just a post to add another one. I am lured to the fact that I want to post useless information on other topics to to make the count.

1. What conflicting information, exactly?
2. You need a COC for the inverter. The PV array is DC and there's no official certification for it yet. 
3. Yes. 
4. Yes

As far as I understand, there are no regulations for the DC side (panels and batteries) in South Africa yet, but your AC side will need to signed off by a registered electrician to ensure it complies with regulations.

Morning Nico
Welcome
From your photo your Replus is almost certainly a rebranded Axpert.
If you want to try out Manie's software go here.
 

Thank you for the response.I will certainly look him up.
This forum has such great stuff and I don't know where to start. I have so many questions but I will start slowly.
