Low cost inverter but seems very efficient.

The are good for grid tied yes, I looked at them a while back, and they are on "the list".

But if Eskom goes off, so does the Solis. So you need a solution added to keep stuff powered like a UPS or some such.

I have used a Solis for over a year now, highly recommend if you wanna save money. 

Load shedding however is a problem due to the fact that it mist switch of when no grid is available 

The Solis inverters are great inverters and come with 10 year warranty. There are some hybrid models with battery backup as well. 

I have a Solis 4G inverter and are very happy with the unit, however I found zero support for Solis in South Africa. I need some technical information but no one can/ will answer my questions. I couldn't even buy my unit from a dealer or reputable store. The only solution was to buy from an online store that knows nothing technical and thus no support. Solis overseas,  India, US and UK refer me back to Solis South Africa who doesn't even respond to my technical info questions. My advice is to stay away from Solis in South Africa as no one will assist with technical issues.

My experience is different. I have a 6Kw Solis Hybrid inverter and works extremely well. Even a loose connection in a cable were detected and the inverter warned me accordingly.

Furthermore, I requested a firmware update and Solis South Africa assisted me promptly contacting me and doing the work remotely.

Thank you Solis!

Hi @Pieter Lourens, are yours also dipping or switching off when loadshedding starts? I have 3 friends with the same inverter and they all report the same.

This is irritating me somewhat. I have added a ups for the TV and wifi but still feels I would have liked it more if it didn't. 

 

Other than that (as we discussed previously) the inverter is great.

Hi @Rolo,

Yes, the dipping as the inverter switch away from the grid tied circuit is normal for all Hybrid inverters. The Solis RHI inverter has a 20 milli second switch over time; switching over is the islanding legislative requirement.

I did notice that the later Solis Hybrid (S6) has a 10 milli second change over time.

I think the issue is the tolerance of this dipping by the appliances. My TV is the only appliance that shuts when the inverter switches.

I hope that helps

This is all about a Solis grid tied only that shuts down when the grid is down. I think the question is about the Solis RHI pure hybrid as Pieter has already given details. 

 

Hi @Scorp007,

My first solar set-up was exactly as described in this video and that works well. Essentially that is a hybrid inverter but split into two.

Pieter this is what I have and I worked it out this way and it was interesting at the time to see this video long after I came up with the combination. 

Also before the video I visited a school friend and what a surprise to see his installer installed the same 2 Inverters. 

Even if I had a bigger true hybrid I will keep my Solis connected. It just does what it must do in silence. 

It stays a good way of scaling from 1 system to the next.

Hi @Pieter Lourens, any advantage seen by doing firmware update?

No, not really.

However it did solve my issue in that sometimes the WiFi logger read incorrect Eskom power when switching because of load shedding. I think that because the CT clamp meter is connected to Eskom rather than to my essential load caused this problem. The metering device switches off when Eskom does.

PS the CT clamp will remain on Eskom, just the Arcel meter should probably have power all the time.

Hi Pieter,

 

Should probably or should? I have the same config, CT clamp on mains incoming and meter powered before the inverter, so when grid goes down the meter goes down. Also throws my stats out of whack. Did you move the meter to be powered from the essential loads, so on AC Backup output?

Hi @LumexClipsal,

"Should Probably" because my personal logic says that if the Arcel meter is constantly powered it will not get a misreading. The specification, however, indicates Eskom as the power source.

I noticed that when Eskom goes off that I have a misreading but as soon as Eskom is back on, the reading is auto corrected. I believe the firmware upgrade helps with this correction.

At some stage I may decide to switch the meters power but that is not a priority now.

If you make changes, please let me know how that goes.

@LumexClipsal,

Following from our earlier conversation.

I rewired my Arcel meter to be powered from the essential load of my inverter instead; and all seems well.
I will let you know should there be any misreading. However, after 5 days I believe all is good

Thanks Pieter.

I think I'll do the same. Is the CT still around the mains incoming at mains DB?

Hi @LumexClipsal

Yes the CT clamp remains as before. Just moved the power source for the meter.

Good Day All,
