Inverter repairs

Hi Naeem,

How many phases do you have? Are the inverters intended to share the load or do they supply separate or isolated loads?

Please provide more information on the set up, for an example:what is the no. of inverters that have been stacked. Are the live and neutrals from each inverter combined when you connect them to your MCB? 

Is it a shared battery bank?

Images of wiring might be useful.

Thank you

Ash

Hi Asher, when you are bored of an afternoon, I have a challenge to entertain you:

Titan 3kVA 96VDC UPS comes on three green lights for maybe a few minutes then enters shutdown procedure and stops.

I must warn you that two "specialists" could not find the fault.

It is of small economical consequence, just out of curiosity I would like a diagnosis before junking it and having to find a new application for its fairly new 8 x 40Ah 12V battery pack. This unassuming inverter has given exceptional reliable service in a lightning prone environment for some 15 years and I want to give it a good chance of recovery before retirement.

I am retired and can bring inverter and coolbox to Fourways at a time convenient to you, or just leave it for when you find time to look into it.

Abe53.

Just for interest. I have an old mecer inverter with an issue, seeing that I stay around the corner from them I thought I'll give them a chance. 

The shop is located in a interesting part of town. Didn't instill much confidence. But I'm giving them a fair chance. 

The shop is filled to brim. Mainly Axpert and Victron inverters stacked ontop of each other. 

 

I dropped it off on Thursday. 

 

I'll keep everyone updated

Not off to a good start.

Inverter was dropped off on the 9th of January.  They promised to email me a quote for repair ASAP.  I waited one week with no feedback received from Caprical Solar.

I phoned yesterday afternoon but they couldn't assist as the gentleman who booked in the inverter was not there. I called again today and was promised that will look at it today. Seems like are very busy and haven't even looked at the inverter as yet.  I was now promised a quote before the end of today.  Not holding my breath...

Best would be to try Mustek or Rectron since they are the only importers of Axpert / Mecer Inverters and OEM components to my knowledge

Also have  a Mecer 5KVA 5KW MKSII with "bus soft start fail" Error 09 which i need to repair and check

Will contact Rectron and Mustek to investigate their repair procedures

i will certainly share any positive info on the Power Forum website afterwards. No reply from e mail sent to them presently

I received my quote to repair yesterday (and I call which I couldn't take) 

R1200. 

I can buy a brand new one for R1999, some places even advertising for R1800.

Maybe on larger more expensive units its worth it to repair, but  on the smaller cheaper units just chuck and replace.

Guys, please don't take your inverters there.

I've been through this with my Axpert. They will take your inverter, not call you back and then expect a diagnostic fee when you finally go there to collect your unit. I chose to have them pay me out R1500 for my Axpert crap so that they could use it for spares.

Guys, this has proven to be one big misunderstanding through missed communications. My post above was meant to be a service to the forum members here but I realise now that my understanding of the events that unfolded around the repair of my inverter was not accurate. I believe that these guys are trying hard to improve their service and I was mistaken in writing what I did.

Forum,

I have been following this thread with some interest.

In my opinion, a stock standard Axpert unit can be considered to be a household appliance like a stove, decoder, washing machine, TV etc.

Ok, there is some sophisticated electronics and software involved, but an appliance nevertheless.

I mention stove, decoder, TV, as I have recently had to maintain all of these.

Stove is a Defy Thermofan oven, probably 20 years old, it needs a new fan, I can choose to buy a spare fan or scrap the stove, and buy a new one.

The TV is an old tube model, has high voltage fault, currently at the repair shop, if no spares, or too expensive to repair, it will be replaced, with new technology:)

Decoder, I recently replaced my DSTV dish (working but badly rusted)), and had the local TV guy run cable to my Extraview decoder.

On all of the above, I have access to agents, vendors, installers, and can choose between repairing or replacing.

Will we ever be in a similar position for Axpert inverters?

My impression is that many vendors import container loads of solar equipment, with very little effort to implement  post sale support and repair facilities? Am I correct?

If Axpert inverters can be manufactured in their thousands, how hard would it be to import genuine spares as well, and offer a repair service, even if it is on a board swap out basis?.

We choose our cars on the basis of after sales service and support, so a Volkswagen or Toyota has a price premium over a Geely or Chana car.

Are we all buying Geely inverter equivalents with no regard to after sales support (No offense intended to Geely, but you know where ! am going here)

I look forward to some robust debate in this respect, forumites – please comment!

Agreed! The term I use is a commodity rather than appliance.

A commodity is an item that is traded for a purpose and is not specific regarding its manufacture. It fulfills a function..

We went through this same progression when variable speed drives (VSDs) appeared on the market. These were flaky to start with and some models were better than others so one needed to be careful. However as the technology matured (very similar to inverters) this difference became less of an issue.

I expect the same to happen in this industry as it grows and matures.

Thanks for your input Richard!

I wonder how far down the maturity curve we are with inverters?

Axpert units seem to have a weak point with the MPPT/Battery charger modules, which fail more often than the inverter.

Would anyone know if it is possible to run an Axpert with a faulty charger, in an inverter only mode, and permanently connect a smart battery charger to the battery in parallel with the Axpert. This is for a backup only installation, no solar panels.

Regards,

Hi Solo

This depends which charger you are referring to. 

The solar charger module on the axperts is a separate unit from the main inverter board and a lot of people get away with running the inverter with a faulty solar charger in this regard. 

The AC charger however is a different story. The inverter uses components interchangebly because it converts AC to DC in order to charge batteries and then switches the same components to convert Battery and/or solar DC to give you an AC output. 

Its impossible for the AC charger to fail and for the inverter to still work. AC charger and Inverter are the inverse of each other.
