April 18, 20197 yr Which Aexpert is recommended? (Considering a dual install of a Solis alongside an Aexpert.)
April 18, 20197 yr Look, they are great inverters for the price. As long as you don't mention them in the same sentence as Victron. There are not that many different models so you would simply pick one that suits your needs. For example (horror) I am looking to get one of their cheap 3KW units as a UPS to supply power to street lights, gate motor and CCTV security camera system in the housing estate I live in. Not planning to use the built in MPPT for this installation so COCT can go and get knotted.

Keep in mind it is not approved by CoCT to use on grid with PV panels connected to it. But it's fine for Offgrid use, or as a UPS. Which one to get? What are your needs? Start there first.

April 18, 20197 yr Author Want to use for back up. Panels connected to the Solis How does the change over switch work when one has an Aexpert?

The same as it would on a generator. IF you want a COC you need a changeover switch between the house & the sub generation input, i.e. it is there to change back to Eskom when needed.
April 18, 20197 yr BTW, this is the best product portfolio overview for Axpert that I know of: http://voltronicpower.com/files/pl/companybrochureB5-forInterSolar.pdf Contains the specsheets of InfiniSolar, Axpert and accessories. Axpert line starts on the page 18. Quite popular Axperts are: VMII VMIII King MKS Speaking of change over, there's a built-in relay in a typical Axpert unit. It's an off-grid design, so the load can be powered from the solar+batteries OR from the grid. Mixing of grid power with the power of solar panels is normally not possible with these units. AFAIK, the only model that is capable of mixing the grid power with solar power is the King.

Had my inverter for 2 months and then it gave the error 09 code. Waiting for responds back from Voltronic to see if they can fix it 🙏 I hope so.

InfiniSolar 5kw and 10kw are pretty good from my experience.

April 19, 20197 yr 22 hours ago, Mistral said: Great idea! Would Mecer brand be OK? If I am not mistaken, the AXPERT / MECER /MPP and a few others are all made by VOLTRONIC? As I understand, VOLTRONIC is the manufacturer, and each of the suppliers brands the units with their name? The MECER is imported by MUSTEK?
April 19, 20197 yr 22 hours ago, Mistral said: Thanks for the useful web link! I'm at the same point, where I am negotiating the virtual minefield of inverters, and which will suit my needs/budget? Hours and hours spent reading posts and watching YOUTUBE videos, and sadly, I feel more confused now then when I started. As soon as I find a unit I think will be a great purchase, the unit is either not available locally, or wat too costly for my available cash? I can import, as I am a licensed importer, but then run the risk of purchasing something with little to no back-up locally?
April 19, 20197 yr Author I think everything is re-badged . Why I mentioned Mecer is maybe they offer warranty support??? In fact other than Victron I wonder if there is any real warranty support/repair locally for any inverter. Such a specialised field. Can't be easy to find people for this job.
April 19, 20197 yr Author This going solar is very frustrating! Minefields all over. Forum is a wonderful resource and I am amazed at the knowledge here. I am sure they are all consultants to Tesla!😀 Edited April 19, 20197 yr by Mistral

April 19, 20197 yr Author Minefields! Lets ignore supplies - most of everything is back ordered. This is extremely high tech and there seem to be a fair number of post installation problems. First you have the AC side - difficult to find sparkies who have a lot of experience with solar. And some sparkies have now taken on installing as well! Then the DC side again not easy to find an installer who really understands the regulations and who I would call an expert. And then you have the COC hurdle and if you are in Cape Town their approval process. Whew! Why is my blood pressure rising. Comrades Marathon looks easy by comparison.

I imagine, making use of a company like MUSTEK, would hopefully offer a better chance of local support/warrantee? I can't comment though, as I have not had any dealings with MUSTEK/MECER. I am not interested in feeding back to the grid, as I do not see how ESKOM would pay a premium price for renewable energy, when they can generate for less than half the cost. I foresee that this credit process will be delayed for as long as possible, and every obstacle possible will be introduced to try to dissuade people from this process.
April 19, 20197 yr Author I am most grateful for the top class advice from forum members - this forum really is a fantastic resource. And the time given to answering questions is incredible!!! Really appreciated guys!
April 19, 20197 yr Even though I am not interesting in feeding in the utility grid, I am still leaning towards the INFINISOLAR inverter range. I think I will end up installing 2 of these to achieve my 10kva end goal. My EFERGY monitor showed my consumption averaging around 2kwh last night, but the dam EFERGY server had issues during the night, and I dont have enough data on this yet.
