    • Hello! I'm an absolut beginner when it comes to solar - just thought I knew enough to install my own solar system but after connecting it all up I got stuck with the programming of the inverter. It's and Axpert Plus 3kva inverter/charger connected to four 12V 230Ah GEL Batteries (Ultracell UCG-230-12), connected to 24 v,  and six  320 watt solar panels connected in series. It all came as a kit and I thought it would just be a case of plugging it all in... So I've seen some info on this website about the settings, and a document called Axpert Settings 1.1 by Chris Hobson but I'm not pernitted to download this. The problem now is that the inverter is showing 0 input v from PV array and the AC led light is flashing green, with no "solar panel symbol" showing. The manual is really not helping me here so please, if anyone can, I'd really appreciate some help here! Kind Regards, Emil  
    • I actually do see it changing. Just not fast enough...
    • He has not at his new build in Sea Point....my mate did all the electrical work
    • Ok, so this topic has gone way off course. By now all of us realise that things are seriously wrong. From an illegal worker stayaway where the unions ignore court orders to the explained downtime on units ascribed to sabotage. This sounds like the famous loose nut Koeberg story from a different century. Can a real expert, i.e. not Eskom employed, please explain how you can sabotage a unit without causing real destruction. When I was doing national service as a youngster I was in the School of Engineers and we visited power stations in order to study them with the view of sabotaging them. It is not possible without explosives. And then to have them back into service 48 hours later..... Really - there is a big difference between sabotage and a breakdown! Who believes in fairy stories. I would be ashamed to say I was working at Eskom as an engineer today If it were so. And then the stopping of lorries story - what happened to the conveyor belts feeding the stations? Are they again not telling the whole story? New Denmark and Majuba are the only power stations trucking coal. If the others have to do it it is because of poor Eskom planning to source their ONLY energy supply. In my neighbourhood watch resides a few Eskom employees and it is clear from the radio traffic that things are not kosher with Eskom. I agree with the view that things will deteriorate to a point untill we are on par with the countries north of us. The point however is that they import power from us and we cannot get power from anywhere else - the few Cahorra Bassa kilowatts will not make a diffference. And this is the cold reality of the government department named Eskom. They will join the ranks of Prasa, SABC and the Hospitals. We all know we cannot depend on those institutions. Even the Admiral in charge of the fleet admitted they are past the point where serious maintenance can help. I am a realist above all and I do not see this situation changing for the better. So yes, if you can leave do it now.  But be prepared to join a 100 million refugees who are also not happy with their circumstances. And don’t think your’e going to love them all. For the people who stay - our forefathers came through and so will we. The strong will survive.
