Yes 230volt is the standard for South Africa

Above ground Borehole coming on every 5 mins or so when no water is running.
Clint replied to Raiden2912's question in Questions & Answers?
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 -
Earth Leakage - Nuisance Tripping On Power Restore
Clint replied to spotity's topic in Fundamentals Of Electricity
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
-
They use IRF740 on the 230 volt side and HY3810 on the low voltage side
-
Hi Douw As a registered electrician I have a dedicated earth leakage tester. I have replaced numerous earth leakage circuit breakers that only trip when there are electrical storms normally the old Heinemann brand. I agree with the other comments that you must connect the earth leakage after the inverter.

New member and new to solar power
Clint replied to Bere's topic in Starting In Solar? Feel free to introduce yourself
Lets see The JA 540 watt solar Panel maxes out at 49.75 Volt and 14 Amps. So if you install 11 in series your Amps will stay at about 14 and your voltage will be about 550. With 2 strings in Parallel you will be producing 28 Amps and 550 Volts 6mm wire can handle about 40 Amps or more depending installation type up to 53 Amps. So yes you can. -
Can you beat this pricing with a DIY solution?
Clint replied to jeddles's topic in Beat Load Shedding
I would rather get ellies or mecer ups(24volt), they would be slightly cheaper and have a capacity of around 2000Watt hours and same lifespan or better. Running your computer off such a small 600w capacity would be stressing the system. Good luck -
Try Mouser

Servicing Evacuated tube solar heating system
Clint replied to Mark M's topic in Water Heating & Pumping
Hi Mark Just clean the tubes from time to time. You can remove one of the tubes and see if the heat paste has not dried up. You can also test the Air release valve . -
I've got the same problem with mine. It seems to work a bit when I put fresh batteries in it.
