Aero-Sharp Inverter HR-INV-X01-015

Aero-Sharp HR-INV-X01-015

The Aero-Sharp brand of inverters were designed for residential use, accepting a string of rooftop mounted PV modules for conversion to 240V AC for feeding back into the grid.

These inverters were commonly sold by Origin Energy (and a few other solar installation companies) as part of a solar package until the end of 2012. They have since fallen out of favour, with most suppliers offering SMA, Xantrex and Sharp instead. There were reports of Aero-Sharp inverters failing at an abnormally high rate.

They are one of the heaviest inverters on the market, owing to the aluminium / stainless steel enclosure and large toroidal isolation transformer.

Technical details

It uses a Mitsubishi PM50B4LA060 50 amp, 600 volt IGBT H-Bridge module to drive the output transformer. The IGBT module is bolted underneath a large heatsink that endows the entire top of the inverter. The heatsink contributes significantly to the weight of the inverter, however the advantage of such a large heatsink is the benefit of a fan-less design, thus improving reliability. But as the heatsink sits horizontally, dust can gather and settle between the fins. Routine dusting is required to keep it clean.

The PV input voltage range is from 150 to 400 volts. The inverter produces little to no output below 155 volts, and remains in stand-by mode at 150v or less. The unit will only power up (into stand-by mode) when the PV voltage rises above 85 volts.

The maximum input current is 10A. With 8 x 190w 24v panels (1520w), the current would be 5A with an open circuit voltage of about 336v. However, a lower open circuit voltage could be used if the panels provide a higher current, such as 12 x 120w 12v panels (1440w), giving an amperage of 7A and an open circuit voltage of 210 volts. For best efficiency, a higher voltage and lower amperage string is preferable, which reduces losses in cabling between the array and inverter.

All three ports/connection points are galvanically isolated from each other. The communications port uses an isolated power supply and opto-isolators. The main isolation transformer eliminates the need for PV modules to be earthed.

The isolation transformer makes up for about 50% of the weight of the inverter. It is a large, high capacity toroidal unit which is bolted to the back of the enclosure.

There is a microphone on the LCD board. This is used to detect when someone has tapped on the front cover/lid, and will activate the LCD backlight for about 20 seconds.

GeneralHR-INV-X01-015

Aero-Sharp inverters are generally well designed. Extensive filtering on both the PV input and also AC grid output largely eliminates most radiofrequency interference. The PV and AC grid ports are protected against voltage spikes by TVS (transient voltage supressors).

Unfortunately, when the PV input is low (less than 50 watts), the isolation transformer presents itself as a light reactive load to the AC line with a very low power factor (similar to a large, unloaded transformer). The low power factor of approximately 0.02 effectively cancels out any power exported to the grid. It is only with a higher PV input wattage that the inverter exports any useful 'real' energy back to the grid (i.e. at 150W with a power factor of 0.7). Therefore, for there to be any benefit, Aero-Sharp inverters need to be operated in their optimum 'power window', usually between 50% and 90% of their rated capacity. At 500W and above, a power factor of 0.95 can be realised, and at 1000W, 0.98 is achievable.

Problems

See article: Aero-sharp Problems (Grid Volt Error).

Remote Monitoring

Many installed Aerosharp inverters are the cheaper versions, i.e. they do not include the kit or connections required for monitoring on a personal computer. On these units, the Com port hole is plugged with a plastic bung. However, the serial communications circuitry is still present on the LCD board, and it is possible to retrofit such an inverter with aftermarket connectors to permit connection to a computer.

Aerosharp made a piece of software called PVMonitor2008, which talks to the inverter via an RS485 serial link. This was never released as a downloadable package on Aero-sharp's website. It is supplied on a CD as part of a PC connection kit. The kit is extremely difficult to locate in Australia, and very few solar companies stock the kit.

As an alternative, the inverter can be monitored using third-party off-the-shelf components and a simple script. See our page on Web-based Aero-Shap monitor.

Ok, you have a 30 watt solar panel which will put out about 2 amps or so in direct sihulgnt. I assume that you have a storage battery and probably a voltage regulator to keep from overcharging the battery.As for the power converter, just assume that it has to run from the battery and the solar panel is just there for charging the battery. Even without the solar panel, you can run any size inverter you want as long as the battery will stand the load. A car battery or anything larger will stand the 300w inverter without any problem. the battery will eventually run down of course. The actual amount of power that the inverter will draw is in proportion to the amount of load that you have plugged into it. Just having the inverter turned on will waste a little power, perhaps as much as 1/2 amp (about 6 watts at 12 volts, volts times amps = watts). If you have a 30 watt load plugged in, you will consume about 36 watts which is about 3 amps. If you run this load for 5 hours, you will have consumed about (3 5) 15 amp-hours. If the solar panel puts out 2 amps, this will take about 7.5 hours (a whole day of sihulgnt) to replace. Increasing your solar array will obviously shorten the time.If you want to know how much you can be running without draining the battery, this is going to be about 30 watts, less the loss in the inverter. This is mid-day with sun directly on the panel, it will be less in the morning and the evening.

I purchased 12 solar panels and inverter from clear solar. 5/2/10 but the inverter has failed, who do i contact for a replacement as it has a 10year warranty. clear solar and the electrician who installed it have vanished.

What do i have to do?

You can purchase replaceable CR2032 lithium coin cell from most places and fitting is not that hard. you will have to turn off power swith in meter box and the pv panel swith located near the inverter allen key will be needed to remove the 4 screws to gain access to battery on the panel that was removed there is link cable that can be unpluged to make it easy to replace the battery when the battery has been replaced reattach link cable and refit panel with screws then turn on pv panels switch and then main power switch in meter box. i have replaced this battery myself and all was ok
if you have any problems leave post and will get back to you.

We purchased an AeroSharp 1. 5 kw inverter through Origin energy, over a year ago and they have admitted that the inverter was faulty since installation, but after complaining for over a year, they still haven't done anything about it. Now they have told us that they are negotiating the service charges with the warranty provider and that i'll have to wait until this is resolved. NOt good enough! I paid $3K for this unit and have not had a cent back from the solar energy produced as it has always been faulty. And i have no idea where to go from here if they dont' replace it?

Hi M Vera. I too bought an 8 panel 1.5kw system from Origin in late 2010, with an Aerosharp inverter. The installers originally placed the inverter on my rear wall, in direct sunlight. This made the digital display rapidly fail in the 38 degree heat at the time. Origin reluctantly agreed to move it inside my brick garage, but only after much arguing, and trying to dissuade me by warning me it would catch fire inside the garage, and be so noisy it would keep me awake at night. The Aerosharp company in Victoria (before going bust) advised me over the phone the inverter SHOULD be inside the garage for sure, NOT on my rear wall!! OMG!! A very stressful period. I have always thought my bills were too high. Last quarter was $320! I was paying that same amount BEFORE I had solar! My neighbours, with similar size systems, are ALWAYS in credit! Very frustrating, and I think I have been totally ripped off. They (Origin) have bullied me along the way, and only ever come to a few TINY resolutions when I contacted the ombudsman. Want to join me in a Today Tonight story? I'm up for it. I'm sick of this despicable company that shows no sympathy whatsoever. Tim

We have had a failure in our unit it has been replaced with a referbished unit our system is a 1500w it use to produce 1520w but the referbished unit does not even make 1000w and origan is telling us that the numbers are good i know we are being told a load of rubish buy a pirson who is a complete diplomat and i am not enjoying the jerney so i think the ombudsman is the next step with evedence from an independent contractor to look at the numbers.take the numbers each day at the same time each day of display and write them down lets all hit this hard and get what we paid for its not fair someone is going to fix this proper. I think social media lets get together and take care of it we did not pay for problems

Hi
I have a TVS failure message on my aero-sharp inverter. It is a 3 KW. Can I purchase the TVS to change it? Can anyone help ie: name and contact of a dealer???

Douglas Higgins, Mon, 22 Oct 2012 06:06 pm: Reply
On 10-09-2010 I had installed a 1.6 Kw system installed through Origin with a Airo Sharp Inverter. The origional contract was for a Sharp Invertor, but at the time of installation the Sharp was unavailable. That Inverter failed after one month and was replaced. The second Inverterlasted just over a month and it too was replaced. The third Airo Sharp after a months operation overheated and only put out half capacity. When the service people came out it returned to normal operation. On Sunday 21-10-2012 the inverter started as normal then at 9am when I checked it it had shut down. It read Mode Stand By internal Temp 46 degrees Grid Voltage 245 volts VPV1 158 volts TVS1 Failure. A green light was showing on run and fault. All day the inverter read the same. I checked the inverter first thing this morning and it was reading the same as yesterday. I waited for Origin to start work so I could report the Inverter had a problem. I was asked to tell the operator exactly what the display was saying this was around 8.30 am. When I went to chech the Inverter was functioning normally. The manual clearly says when that fault shows parts have to be replaced for the inverter to function. If that is the case why is the inverter still working. Is there a problem with the Electronics to be giving wrong readings and shutting the Inverters down. I have had problems with all 3 Airo Sharp Inverters and the Installer has had no feed back from the supplier which indicates there must be problems. If they do not function as they should then Origin in good faith should replace all Airo Sharp Inverters they signed contracts for.

My Aero-Sharp inverter is displaying "BIT Failure; System error". According to the manual, this is a Category 1 fault; any ideas to get it to work? Thanks
Marty, Wed, 31 Oct 2012 09:03 pm:
A BIT error indicates a Built In Test error. The inverter performs a self-check when it powers up, and if certain parts are not working properly, it fails the test and will not go any further. It could also be due to an internal software error.

You will need to contact your installer to have it checked, and most probably replaced.
Jason, Mon, 07 Oct 2013 03:33 pm:
Tim I have the same problem "BIT Failure; System error message on the LCD screen, I've checked system voltages and any damages on the PCBs inside the inverter but nothing out of the ordinary. These inverters should have 5 years warranty. This makes me wonder is Aero Sharp reliable!!!

Leonard, Thu, 07 Feb 2013 11:33 am: Reply
You mention that "most Aero-Sharp failures can be attributed to the use of an under-rated fast blow fuse (HRC). Replacing it with a slow-blow version generally fixes the problem."
I have a "Grid Voltage Error" message, even though I am getting 248V at the inverter from mains. Can you provide details on the type of replacement fuse required and how to replace it?
Thanks.
Dean, Wed, 01 May 2013 03:49 pm:
If your inverter is showing 248Vac on the display, then the fuse is not the issue. However, if this is just the PV voltage then the fuse model you need is Bussman FWC-16A10F for a 1.5kW inverter. You can order these fuses through middy's, ideal electrical, awm and L&H electrical wholsalers for about $30 each. Beware though that if there is a fault that causes the fuse to blow you lose the cash but not the problem.

You really should get your electrician to replace it though as there are some extremely dangerous voltages present inside the inverter. Always disconnect both the AC and DC supplies, FOR AT LEAST 10 minutes before opening the inverter and be careful of the front cover as it is easy to damage the sockets that the ribbon cable is attached to and if you do that then you are in for a world of pain trying to source parts.
Jon, Fri, 30 Aug 2013 03:52 pm:
Hi, I have a grid volt error on my Aero-sharp 1.5kw inverter. I found the 16A fuse is blown. On their online manual it says that it's supposed to have a 20A fuse. Do you see any issues with replacing the 16A fuse with a 20A fuse?
Deb, Mon, 25 Feb 2013 11:03 am:
I'm getting exactly the same message in the last few weeks. Turning off and then back on resets it but this is obviously not the long term solution. Would like to know how to fix this as well.

Hello,
Im contemplating a setup but grid voltage may be a problem. i know the providor can fix that, but if it occcurs and the unit is showing a "grid volt error", and this grid error is caused by the grid voltage increasing when the inverter exports >2kw, will the inverter still export power at <2kW while the error is in effect? or complete cut off for a while?

Charlie.

Hello,
I have the 3kw version secondhand and it uses the PM50B6LA060, the difference is that its capable of stepping up the two PV inputs. There are two more large inductors inside it (the first being a filter).

Hi, I had a "Grid Volt Error" from my Aerosharp solar today. It never happened before, but it seemed to happen after the Smart Meter was put in this week. I just turned it off and on again and seems to work fine, but am a bit worried as I am no longer with Origin who were the ones that handles putting it in about 3 years ago.

I purchased my solar system from Solarswitch in July 2010. This system contained 2 Aero Sharp Inverters and since then I have nothing but problems with the inverters 3 times they have been replaced and today I noticed that 1 on the inverters in again not working. If you’re Inverter needs replacing look for another brand that has a good reputation. I am now looking around at replacing both inverters with a reliable brand. The company that imports these inverters as in Melbourne but unlikely to get any help from them as I have tried.

I presume because of your involvement with aero-sharp inverters, you may have the schematics, are they available.

As to my second question. Every inverter, say, for household use, requires a minimum DC voltage to switch the inverter ON. Especially, in a workshop where PV are not installed, what DC power source would would recommend and at what current settings.

I have a Aero sharp installed in 2011 by energex and it has never given me any problems, I was told by the installer that a large batch of inverters came in and where faulty but I seem to have been fortunate. I have just been advised to install 2 more panels. I have done that and so far all seems ok I was running 7 X220 Panels I have added 2 x 250 I was told the could get 220 and these will be fine they will run as if they are 220 ? who am I to argue > I would appreciate comments r.k.cole@bigpond.net.au I am trying to find out what all the numbers in the window are ??

I've been having nothing but problems with this Inverter. We frequently get power outages and when I check the box, the fault light is on and there's a 'grid volt error' message displayed. This is our 3rd replacement box and I'm thinking enough is enough. It takes over a month for the clowns to action a warranty claim so in the meantime I'm paying for power. Soooo frustrating.

My inverter was sent back to Sharp Sydney for inspection. First was asked to pay for the return of the inverter then another $100 to look at it. It still has one year on warranty installed under Origin plan in late 2011. Now Sharp have emailed to say the problem is not under warranty and can be fixed for $350 plus $150 delivery back to Brisbane. They say it is an extraneous problem but can't say what caused it. Have had Energex out to look at meter box and lines nothing has happened this year to cause this. But Sharp still won't way what is the problem. So if they fix it or I buy new can it happen again. Yes they say. Very hard company to talk to. Can talk to Malaya but pretty useless and won't give you the Sydney number.

Just had a 'grid volt error' show on this particular Aerosharp model on a 1.5kw system installed by True Value Solar on 30/8/2010. The internal fuse is blown and perhaps changing the MOVs and an upgraded Bussman fuse may solve the problem but in any case the supplier has agreed to replace it for another brand under their 10 yr warranty terms.

Unfortunately Aerosharp are no longer available and the company went into liquidation years ago. Check with who sold you your system and ask them to warrant a c/over. If they are not around either you are unfortunately going to have to purchase a new inverter and possibly upgrade the whole system to be compliant with todays standards. If you need any advice give me a call on 0413708649.

No daylight saving here in Qld - the thing started subtly 'screaming' as soon as sun hit panels - and I don't wish to get up 5.30am! Wondered why I was always waking with a headache. The installers didn't bother warning me this cld be a problem (typical) but still had to pay to get them back to relocate.
