I also use Pro-tek 7;1;3 Its brilliant

check TDMI

Sarel I,ve never seen a single surge protection before,I'm sure you have to use a 2 pole(live and neutral) I'm not sure

Correct I use a E/L tester at every job I do. I also find that all the E/L I test the test button has always indicated if the E/L is functioning correctly. Maybe one day I,ll find one that does not.

Correct

Just push the test button on the earth leakage ,this could give you an accurate account if it is faulty. remember you cannot go from one EL to another one My theory is when the power is on you have a neutral to earth wire short. Try disconnecting all the neutral wires and connect one at a time to find the fault For gods sake dont electricute yourself(I'm a registered electrician) Good luck

Check for a hissing noise from the pump and make sure the pipe from the tank is bigger than the pipe going out of the pump(this is cavatation and will damage the impeller) I hope this helps

.

Yes 230volt is the standard for South Africa

The built in non return valve could be faulty ,the water is just going back into the tank. Check if the pipes from the tank to the booster pump are bigger than the pipe after the pump ,this could be causing cavitation (this would be heard as a hissing noise) good luck

I think the pump is damaged. Pull it up and see if the cable is damaged. You could be overworking the pump (blocked pipes)or wet end (pump part) damaged good luck

I think getting a length of 80mm LDPE irrigation pipe and cutting it length ways and just putting it around the tubes is a better idea

I meet dodgy electrician's all the time. I was told of an installer today that issued a COC with a different installers signiture on it. The COC was yellow paper ,if I'm not mistaken all COC's are now a white form. As a registerd electrician I have a card issued to me by the Department of Labour ,ask your electrician for his card before he or she starts the work.

According to SANS 10142 it needs to be replaced . Be careful your insurance company wont pay you out if the SPD's arent working.

McGuywer Generators produce a pure sine wave just by design . An AVR is good because it stops the voltage from going to high.

Awesome topic Looks like I will be studying SANS 10142 tomorrow

Agree The Capacitor theory is very interesting.Those damn old flourescent lights are just a fire hazard,replce them with LED lights ASAP

You must feed the inverter through a 2 pole or 4 pole circuit breaker from municipal supply and bypass the EL in the main DB and put a circuit breaker and EL after the inverter and make sure all neutrals are seperated on 2 seperate bars in the DBs I hope all the other sparkies on this forum will check this.

Hi everyone I installed a 16 tube system on my sisters roof with a 12v panel and pump. The pump was very noisy and failed about 4 months later. I went to my suppliers and bought a plastic pump which to my surprise was a Grunfos. A lot more expensive about R1400 vs R470 It works extremely well and very quiet

I installed a 24V 100ah 2 days ago and seems to be working well I will let you know how it works Customer is very happy

Hi Marius2001 Thanks again for the Axpert remote control. I collected it today and it works perfectly. I am now able to program the inverter with it.

DM sent Thanks

Hi Chris I have already checked the switch.I do have spare switches My Inverter is showing an error with the fans (01).I dont know if that is blocking the program. I can access the program with Watchpower I'm opening the inverter tomorrow and I will see if I can find any faults. Thanks a lot

Hi Schalk I'm sure you need 2 red and 2 black wires in the 4 core cable then . I'll check SANS book tomorrow.

I need one aswell I bought a second hand 5kw 48V and the enter button is not working,I can change the program with Watchpower software. I dont mind paying for one and shipping
