April 3, 20242 yr I need to put up 2 of them. So far I found :https://electromannsa.co.za/shop-the-latest-affordable-gadgets-online/wifi-2000w-solar-micro-inverter/ R 9000.00 Most expensive so far but I can trust the shop atleast also DEYE brand https://www.takealot.com/2000w-micro-inverter-single-phase/PLID91176748 R6138.00 https://www.aptsaonline.co.za/products/deye-2000w-microinverter-single-phase-4-mppt R 4,680.00 No clue if I can trust them and the cheapest so far. Anything else you guys can recommend? Edited April 3, 20242 yr by Stefan Cornelissen

Anything else you guys can recommend? I've been looking at these also for a while. APT are selling on takealot so buying direct is probably cheaper. I just wonder about warranty issue. I asked herholdts about these last year and they said they would get them in the future. Maybe send them an email.
April 4, 20242 yr Is the limitation of only to be used on 60 and 72 cell panels for the Deye version not a problem. My be I am biased towards the Solis string inverters vs micro inverters. The Solis 2.5kW needs the same start voltage of 60V but only 1 tracker. From the 3kW one can get a 2 x MPPT inverter.

Off grid garage is using the Deye micro inverter on 600W 144 panels.

April 5, 20242 yr Looking at his links he used 150 cell panels https://off-grid-garage.com/solar-panels-and-connectors/
April 5, 20242 yr I have this microinverter, bought from Aliexpress a few years ago. It's branded MarsRock, but is identical to the DEYE. All I can say is that is has been working flawlessly for past 2.5 years or so. However, I did not place it under the panels, rather in a shaded area. The monitoring platform it uses is Solarman, which is a cloud platform. It's OK, gives you the information you want, but the data is refreshed every 15 minutes or so, so not real-time monitoring. The microinverter has a 60v input limit for each MPPT. My setup was 2 x 455w panels, each into a separate MPPT port, and another 4 x 100w (in 2s2p) to the third port. My 455w panels are 144cells, half cut. I think that as long as your panel is under the 60v input, you should be fine. I recently took this microinverter out of service, because I wanted backup energy storage, so now my panels are connected to a hybrid All-in-one MUST inverter. Edited April 5, 20242 yr by meetyg

Will see how it performs and report back

Just a simple qeustion did you feed it in before or after earth leakage?
April 12, 20242 yr Actually, mine was connected through a socket. Not according to regulations, I know, but worked fine none the less. I would recommend connecting yours to a dedicated breaker in your consumer unit. I did not have any RCD tripping problems, but you might need to test your setup in order to decide if it should be before or after earth leakage/RCD.

I want test it on the plug for a bit then after I get second one I am moving everything to DB with proper cable etc
