Jason - Please do me a favour and check your web certificate. My BitDefender complains that the certificate is invalid. Then - I am in Pretoria. What's up?

Hi Thulane - NO - This unit is 5KVA max - Your stove could get to 3KW and Geyser to 3KW so NO - In my case the Stove dies on loadshedding and we run gas and the geyser is on its own collector with a GeyserWize WiFi controller - so this may give pwer when the collector cannot manage but NOT from the Inverter.

This is going to be an absolute deal breaker. The fans on these units scream depending on workrate. You cannot put them in an enclosed place UNLESS - like in my case - I built the whole job into a kitchen cupboard, used isolation to deaden the sound and installed 2 silent Xpelair fans with thermostats to keep everything under control.

Since this chain is relevant, I have decided to share my experience: I have 6 x 410watt Canadians giving 2.4 Kw to a LuxPower 5Kw. Battery is a 3.6Kva LSB. Running 18000btu aircon, 0.75Kw pool pump, 400 watt basic stuff and when fridge is OFF then at night we run at 200watt. The geyser was a previous project and runs on a water heater sun collector. You can read about my disaster on another forum, this is the result. The LuxPower is amazing. Has blend capabilities second to none. My first full month of use has changed my metered use from 1137 KWH to 730 KWH, a bit disappointing. ( a lot of cloudy days - maybe it will get better. ) If this is the rate of ROI then the total installation cost of 64K is going to take 55 months ( at current electrical rates ) It remains to be seen how long the LuxPower will last. Is this worth it? Considering that I work from home and make my money using computer systems - I think yes. Final thought. This is NOT something to tackle without research and assistance. If you have doubts, get a reputable company ( a very scarce item ) and BEWARE scamsters. This space is absolutely soaked with chancers.

Can I add my 2 cents worth. https://wholesale-solar.co.za/product/6kw-lithium-ion-batteries-black-friday-month-50-off-sale/#reviews Notice the 2 photographs do not match. The sideways shot shows the front of a LCR battery which I bought 2 weeks ago from Sunrun(Pty)Ltd who also disappeared off the face of the earth. The battery I received was in "original packaging" and seems to be all right. I was also supplied with a manual and then when I started asking for the comms info for the can-bus the company phone went on voicemail, the site died and the emails are returned undelivered. I have been able to trace "LCR Battery in Hong Kong" and have asked for more information. I have been chasing a number of websites that all seem to end up with the same voice with either a Peter or a Mark answering the phone. The trick is to ask a technical question and then the fun begins. Can anyone contribute to this argument.

We share the same instruments. Shows my age. If you measured in ALL switching combinations you need go NO further. The obvious errors don't exist.

Hallo Antonio, My electrical engineering background and @Bloubul7quote of the regulations agree that back emf during system switching can cause you to lose the system as if you had a lightning strike. Some systems could be better than others BUT the rules are not there for nothing. If your inverter - at any switching combination - shows a potential of more than 0.5volt between its INPUT E to N or its OUTPUT E to N OR you are nuisance tripping your EL device - you may have a potential problem. There are numerous publications that describe the effects of back emf during transfer switching whether it is manual or auto. In my case I probably forced the issue in that I instructed the contractor to go through all the operating modes. The intention was that I could prepare a SOP manual that would assist my household in case of emergency. It turned a pleasant day into a disastrous one.

And that is exactly why my brand new installation blew the MPPT controller in the hybrid inverter during commissioning. The 5KW system was installed by a local electrical contractor who was supposed to know better. They installed a manual transfer switch so that we could work on the system when in bypass (Mains). The first time they switched from inverter to bypass and back - the MPPT blew up because the inverter no longer had a N to E bond. I am now battling to resolve this crises just before the holidays. I should have been enjoying my savings, instead I am forking out to remedy the errors.
