moec Posted March 18, 2020 Share Posted March 18, 2020 Hi Guys I'm tired of load shedding and would like to 'keep the lights on'. I know very little about this so I am looking for advice. I'm looking at the Mecer axperts but I am confused despite reading many of the posts on this topic. I feel like I have the following options in my price range: 1. Axpert mks ii 5k 2. Axpert mks 5k 3. Axpert King 5k I want to start of with a 4.4 LIPO4 battery and then expand in the future with solar panels. Please can someone advise me on the above options. Thanks Quote Link to comment Share on other sites More sharing options...
SYC Posted March 18, 2020 Share Posted March 18, 2020 (edited) Axpert King IMO with 2 x 3.5 Pylontechs to start with I've used them all and King works the best IMO Edited March 18, 2020 by Quat Allah As Shams Quote Link to comment Share on other sites More sharing options...
moec Posted March 19, 2020 Author Share Posted March 19, 2020 Thanks appreciate the quick response. What are the advantages of the King over the MKS? Quote Link to comment Share on other sites More sharing options...

SYC Posted March 19, 2020 Share Posted March 19, 2020 Than you might want to look at NRS approved inverter http://resource.capetown.gov.za/documentcentre/Documents/Forms, notices, tariffs and lists/Approved Photovoltaic (PV) Inverter List.pdf Quote Link to comment Share on other sites More sharing options...
Denarius Posted March 19, 2020 Share Posted March 19, 2020 Disadvantage of King is you can't run multiple units in parallel, so if you buy 5kW then that is your max with no option to upgrade. If you run the MKS II then you can parallel lots of them, but you don't have solar and grid blending as mentioned. What does that mean exactly? When solar + battery isn't enough to power your loads then the grid will fully power the load while the solar charges the battery. Another scenario is let's say you run geysers in the middle of the day and during that time you want to augment solar with grid instead of battery to put less strain on battery: can't do that with MKS II.

moec Posted March 19, 2020 Author Share Posted March 19, 2020 @Quat Allah As Shams Thanks. I'm not keen on grid tie at the moment. The cost is just too high and not viable. @pierre. Interesting point. 5kw will be my max but the benefit of the blending seems more attractive as long as I am satisfied with 5kw. Appreciate the advice guys.

Tariq Posted March 20, 2020 Share Posted March 20, 2020 Dealt with Bonanzatech, owner Alberto quite pleasant to deal with. I bought a VM iii, it also has the SUB function, which is supposed to blend, have not hooked mine up yet, so cannot confirm, but a lot of discussion on the forum Quote Link to comment Share on other sites More sharing options...
moec Posted March 20, 2020 Author Share Posted March 20, 2020 Thanks. I ordered from mhn.co.za. Will give feedback when I receive it. Quote Link to comment Share on other sites More sharing options...

My bad. Quote Link to comment Share on other sites More sharing options...
Denarius Posted March 21, 2020 Share Posted March 21, 2020 Looking at the King manual I guess one disadvantage of King is a solar voltage is 60VDC~115VDC while MKS II is 120VDC~430VDC. So with the king you will wire more panels in parallel. Quote Link to comment Share on other sites More sharing options...
Beat Posted August 24, 2020 Share Posted August 24, 2020 I just installed my system with MKS 5K, 9 330 W Canadian panels and 9.6 kWh battery. It works well so far and is very versatile. It's advantage is that it can operate with a remote control panel. I'm still in the tuning phase but I think I got it. It can be used with solar panels or just as a powerful UPS. Just a matter of programming it but very easy. The advantage of the higher solar panel voltage is to keep the current low. I arranged 3 banks of 3 panels in series each. That makes a max voltage of 112 V and a max total current of 26.6 A. That can be handled with 6 mm² wire. Quote Link to comment Share on other sites More sharing options...
Jay-Dee Posted August 25, 2020 Share Posted August 25, 2020 For those still following this and new comers... The above statement of the Kings not being able to run in parallel is incorrect and they definitely can (not only the Kodak units version). The newer builds also come with the parallel cards pre fitted. The main advantage of the King is a zero millisecond transfer time which is great for sensitive equipment (CCTV, Servers, Networking equipment, etc) As mentioned above, the dis-advantage over the MKS is the PV voltage which results in running fewer panels in series but more in parallel Quote Link to comment Share on other sites More sharing options...

I couldn't find any specs or infos in the manual nor manufacturer contact information to ask. Where can I confirm that information for the Axpert King inverters? I am using it for load shedding and want to expand with solar. Quote Link to comment Share on other sites More sharing options...

I am using it for load shedding and want to expand with solar. The Kings certainly can - I run 3 of them. It is a double-conversion device, which means all incoming power (PV and grid) get converted to DC, and all loads are powered from that DC (and the battery) via the inverter. Some people get confused about the difference between grid-tied and hybrid - the King is hybrid but not grid tied. capkasa and SYC 2 Quote Link to comment Share on other sites More sharing options...
