I just had a chat with a guy from Powerstore.co.za. I told him I need an inverter able to combine solar, battery and grid and not to export to the grid.

He told me that a new model of Axpert can do that but he does not have it and maybe he will have it in January next year.
Does anybody know what model it is?

I believe it is the V series that Jaco bought

Hi virge, it might be the V-series that I have. It's like 90‰ Axpert, with some grid tie futures from the infini. Not as advanced as the infini bit does a pretty good job when it comes to mixing power sources.

Fullcirclesolar stock the Infinisolar V series but not the 5kW version. If Powerstore import the 5kW I would buy one.

This guy was talking about an Axpert, not Infini. There is an Axpert V series on the Voltronic web page, have to download the manual and see if it can combine power sources. I do not want to export. The Axpert 5Kva worked like a charm till the lightning melted half of it but did not combine with grid when more power was needed, just switched to full grid supply.

The Axpert V series seems to be exactly the same as every other Axpert in that it is not a true hybrid and cannot combine grid and solar power. The difference is that it allows for a much higher equalisation charge (61V) with a schedule for automating equalisation.

 

The Infinisolar V series which is in fact based on Axpert architecture has hybrid capabilities and limited ability to GTI.

 

Voltronic are going to get themselves into an aweful mess with there model numbers. It was fairly logical up until recently but they have stuffed it up in the last 9 months or so.

Voltronic Range
Axpert range is Off-Grid (PV/Batt or Grid only bypass)
Infini range is Hybrid (Grid/PV/Battery)
Enersolar is Grid Tied only (Even a IP65 + a 5 Year Warranty for one model)
Then in each of those you get different bells and whistles

So which one will combine solar, battery and grid and not export to the grid?

The Infini, just set grid export to zero in settings.

Thanks. 3kw is too little for me and the Infini 5KW is out of my price range. I would buy the 3KW if I could connect 2 in parallel. More tempting is the Imeon 3.6 which is in the 35 gees range and can combine 3Kw solar with other 3KW from the grid so if needed it gives you 6kw

I would be rally great if the Infini 3 kw could give you 3 kw from the inverter and combine it with other 3 from the grid.

I would buy a infin. Awesome inverters. It's worth the money !

I think it can?

Allow me to but in just this one time (again?) and point out that a 3KVA Multiplus is 27.5k and for the remaining 7.5k you can get a fairly beefy MPPT (150V 45A for example). It will require a little extra in terms of CCGX (or beaglebone/Rpi plus cabling), and since it has a 50A transfer switch you can stick a full 12KVA through there. My house trips the main breaker at 15KW, so this gives you some idea of how capable these things are.

Thanks guys for help. You are really great. It is difficult to make a decision. I have to make up my mind in 2 weeks. the insurance will pay just part of the damage because they said I was underinsured. be sure to call a broker or ask the insurance to send someone every year to check if your property is properly insured. the building has to be insured on the replacement value not on the market value. i was insured with 30% over the market value and I thought i was ok.

Look at the Infinisolar V series. If you are replacing an Axpert all you wiring etc will be nearly the same. R16k with Fullcirclesolar. They have 4kW units.

Thanks Chris. Can you set export to zero on it? Why Jaco thinks this is a crappy inverter?

Why is the Infini V series black? Next time the municipality will inspect to see if I am not stealing electricity will blame me for exploitation also.

Is this not an Infini inverter? If not, what is the difference?

The infini can do that - combine grid and PV/batt to supply loads of more than 6KW.

Thanks superdiy. So you have an Infini 3KW inverter and can program it to import part power if needed and in case you need say 5.5kw, the 3KW inverter will give you 2.5 kw from PV, 0.5 KW from battery and 2.5 Kw from the grid with no problems? Can you program it not to export to the grid? If your inverter can do this why then the Imeon 3.6 is a better inverter? Is it just marketing?

What is the price for the infini 3kw plus? Do you know where I can buy it from here in Joburg?

I would also like to buy.

I am going Goodwe 5KW this time around. My Infini 5KW blew up as a result of rain. the Infini is also very noisy. It works well but the dust and the water gets to it.

This time I am going IP65.

You can not run the 3KW in parallel as I told you in a PM. The 5 and the 10 can.

The Infini V is the Axpert that can grid tie.

If you place your house on the load side you can not exceed the load of 3KW, yes it will handle a spike and will go to 200% for about 10min but that is pushing it.

If you want to run more power that what the inverter can handle then you have to run your heavy items on the grid feed side. Also remember that your meter must support feedback.

 

Hi JDP,

I do not want to get into complications with feeding back power to the grid. Also, I have prepaid and my meter does not accept feedback and I do not intend to change it.

All I want to do is to be able to use more solar power in case the need is higher than solar. The Axpert did not combine grid with solar so now I need to be able to use part grid when needed. I would need at least 4KW. The Imeon can give you 6 KW continuously but it has trade offs like the inverter part being only 3KW, the Axpert is better than that. Not that I have more PV power available, I had only 3.6 KW (12 x 300W Yingli panels) which now I have to replace after the lightning damage.

Will you be able to program the Goodwe not to export power to the grid? The best price I got for this is R39,400.00 VAT incl.from the powerstore but it is a Reneplus not a Goodwe, I was told it is the same inverter.

Right now I have to decide between Imeon 3.6 and Goodwe. For me the Imeon is tempting because gives 3kw when needed during the day. I do not need it to be water proof and a bit of noise is not problem as it will be installed in an empty room in the house.
