So Voltronic reads and values opinions expressed on this forum. (No not really but one cannot resist the idea that they are eaves dropping):lol:.

I am a happy Axpert user but am all to familiar with its short comings.

My opinion is well documented.

Well the Infinisolar 4kW Super has hit our shores, maybe this happened a while back but I only noticed now.

What do I like about its specs?

Infinisolar 4kW Super Product Spec Sheet.pdf

  1. A 4kW inverter - for my off-grid install the 3kW Infinisolar was too small and the 5kW Plus was too expensive. This is a ½way house in terms of capability and price. It can be paralleled if needed.
  2. High voltage MPPT (500V DC). Single string array with no need for combiner box and much thinner home run cabling and fewer losses. 
  3. BATTERY CHARGING - and TTT is going to like this max is 66V. You can charge Trojan's with this one.
  4. It is a true hybrid.
  5. Control of inverter uses the same commands as the other Infinisolar and not the same as the V series where control is rather crude.
  6. The topology is the same as the 3 kW and the 5kW and so can be installed without batteries.

 

I am not sure of pricing but probably at the R25k mark.

@Chris Hobson , hope you are well, just logged in for the first time in months to report back on my V series and found this post. The V 11 series never made it to our shores as they did not make the certification as well. These has, and I got offered 2 of these as replacements for my units, it is sold with the certificate. My old inverters are boxed already and the courier will collect them on Monday, will have 2 of these units on my wall by latest next weekend. Will report back as soon as I can with feedback on their performance.

Other things the Infinisolar Super  has is

  • dual inputs (grid and gennie)
  • dual outputs (one of which seems to be limited to 500W - a modification on TTT's big inverter/small inverter idea (I think I have not read the manual in detail).
  • battery temp compensation for charging.

I've been looking at the Infini Super for a long time but the first ones available in SA was quit expensive at about R35 000. The price is now almost half of that which makes it excellent value for money. It is definitely my first choice when I upgrade. Another plus point is that you can parallel up to 6 units. So now you can have a 8 kw full hybrid inverter with 10 kw of PV input capability for less than 40 grant - beat that.

After reading this post, my first reaction was to regret pulling the trigger so fast on the Infini V 5kW. Compared to the 4kW Axpert, I like the fact that i can, for 99% of the time, run my household without having to play Power Police - doing things in parallel like in the old days, and not serially. Yesterday - a washing day, we used the washing machine, dish washer and geyser on at the same time, plus a 500W panel heater. For the first time in 5 weeks since installation, I heard the unfamiliar (now) beep beep to signal overload. ICC was showing almost 7kW draw!. 

Sure, the new plus 4 kW is less expensive, but buying two at the same time is a stretch.

So, my recommendation for a family of four with mild "green" tendencies, one can cope with a V 5kW (with a non split DBB)

For a larger or more normal family, a dual Super 4kW would be super.

What I liked about going for a 4 kW setup first, is that it made all the occupants of the house power aware, so the behavior is now entrenched!

Just some pics of this inverter. 2 of them just arrived today, still busy with some much needed maintenance on the batteries while the system is off and still need to change the wiring on the PV panels to almost all in series before I can fit these.

Must admit, they are in a completely different class than my InfiniSolar V,s. Everything from physical size, weight, quality, there is just no comparison at all.

I ended up paying in, it wasn't a no cost exchange as the supplier offered with the Infinisolar V 2 deal, but paying a mere R875 per unit was absolutely worth it.

Ok Jaco - a update as soon as you have made the switch.

Not much to say, they are working and I am still trying to get to terms with all the functions. Ive got way to little panels to compliment the capability's.

These can take either 12 x 250Watt panels in series, or 10 x 250 in series in parallel with another 10 in series. I only have 9 in series for each machine. Mppt switches on at 110 volt and that happens at 06:10 in the morning (in the winter).

Stuff like setting the charging currents are a feast, you can increase and decrease the settings in 0.1 Amp increments compared to the 10Amp increments of the previous units. 

It can really do the 66 Volt charging, so my Trojans will receive their first equalization charge this weekend.

Added benefits include. User defined limits on export wattage, user defined settings on battery usage while in hybrid mode and then the full range of Power management settings of the other infinis.

I know this might be included in a lot of other types of inverters, to me this is all very nice functions compared to my Infinisolar V's

If there is any specific questions about the units or something you want me to test, I will try and do it asap.

Good to see, CoCT is updating their list and adding new inverters. These 4 KW was only certified 09-2016 and officially released in SA a couple of months back, but its already on the list. Now I can start my application all over again.

Note: The inverter has single-phase mains surveillance and is not able to communicate with each other to detect an out-of-bound voltage on all three phases. According to NRS 097-2-1 an external three phase mains surveillance unit is necessary for installations above 3 kW to detect an out-of-bound voltage condition on a three phase system. The inverter is intended to be used for single phase installations only.

Hi Mark, sorry, I only saw this now. Thanks @plonkster for answering. 

Mark just look at Certificate a few posts up. the note at the bottom is the same as the fine print and Plonks answer.

Hi @Jaco de Jongh

Did you take the communication module with it?

If Yes what module is the best? I presume it depends on your application. SNMP module is best I would think?

What software do you use?

So I have given up hope getting my 3kw Infini to work with the modbus power meter and my pre-paid power meter.

So far I know the only true ZERO consumption invertor is the Goodwee unit.

I was hoping this 4kw Super would be the unit to kick the Goodwee in the nuts!!!

Has anybody used the Super with a modbus power meter for the use of ZERO consumption?

I purchased two infinisolar 4K super inverters in May 2017 to replace the  two axpert units I had to be grid tied.

They were installed in parallel and both units had 12 x 250w solar panels each in series as well as 4 x 12v 180ahr batteries.

Here is my experiance with them.

One lasted 10min. after installation. The dc circuit blew up.

Took both units in to supplier.

The manufacturer admitted to having problems with the dc circuit. 

Both units dc circuit boards were replaced after 3mth wait.

Before and after repair the units did not work correctly in parallel.

After a discussion with supplier after a week was given new firmware to install.

Units worked correcty for about 1mth with new firmware and the same units dc circuit blew up.

Took the faulty unit in and has been returned after 2mths.

The supplier has told me that I will have to bring back the units in the new year as the manufacturer is redesigning the dc circuit board and the old ones will need to be replaced.

The supplier has been very helpful however I do believe the manufacturer has marketed these units prematurely without testing them properly.

During this ordeal I have had 5 power failures without being able to use the units.

For me the investment for the units, solar panels and batteries have been a bust and I am just hoping the new dc circuit boards will solve all the problems I have experianced.

Thanks for your feedback Peter. I was just about to click BUY for one of these to replace my Axpert, and though I had better check feedback on the Power Forum (since I have been away so long)... And bingo, your alert popped up.

I only have a single Axpert 4KVA, so this would have been an ideal/simple change over. I cannot take the risk of being offline/mains only, and with suppliers Jhb based, not an easy return/swap.

Are there any others who can give their experiences with the InfiniSolar before I push that BUY button?

My enthusiasm for these units has waned. A local install here in the Karoo also went West. I will say the supplier pulled out all the stops so it was repaired in record time. I cannot have an install do that. My reputation is more important than that and my clients will not tolerate "the supplier is fixing it". I would have to carry stock to swap out and I don't have the capital to have a couple of units lying around.
