On older FW mine would clip at 21A but there was a big problem. If there were intermittent fast moving clouds and the current very quickly hit the 21A it would sometimes cause a DC over current error and the inverter would shutdown and restart. 
Since upgrading the FW and it clips at 19.5A I do not have that problem anymore. 

The prices on their site is just not possible 

I know someone who thought they would save money going gas hot water. Gas costs him R1000 a month. 
Gas geyser same price as evacuated tube solar geyser that I have had for 12 years. Only have to use electricity in winter and really cloudy days to heat it a little or I just leave the element breaker off. 
The new solar geysers are so efficient. Mine is outside on the roof and in winter it's still warm enough to shower the next morning. 

First check for DC voltage at PV2 breaker. If there is none then you have a problem with connections or a faulty panel. This is really a qualified persons job. Best to find another installer.

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.

Dear Empowered,
Thank you for referencing the information. Regarding the grammar situation, this is being rectified. As you are all aware, there is a lot of pressure. Here at SAPAC, we are working against time to improve the industry.
However, to clarify the grammar mistakes, they are being rectified one post at a time. As you are also aware, most electricians are playing catch-up with [fixing] illegal installations.
I can assure you that the site is legitimate and that SAPAC is part of the community within the electrical field.
Regarding the issues being identified, we are working in accordance with a set of specific procedures to ensure that those who do not comply are eventually held accountable, so to speak.

@Chris_S,
After the F/W upgrade and remote reboot, the S portion of F/W version didn't display. Didn't bother me, till I started testing other data functions, and after a few hours of fiddling, decided to give the inverter a cold boot, and that produced the complete F/W version, etc.

I have just chatted with Sunsynk's helpdesk and they acknowledge having a data/programming problem and request 24 hours patience to fix the issue.

I'll do so tomorrow morning. It's on spare laptop with no email on it. I'll transfer the file and send to you. 
Not much was changed only 4-5 voltage settings. Stock parameters are fine until tomorrow. 

I got mine done by Natal Electroplating very nice owner and good job was done. Very happy.

Alkara electroplating speak to Peter. Did an amazing job on mine and same day service. Nickel is what you want. 

I ran my sunsynk 8kw with no batteries for a few weeks. Just panels and grid. It worked fine. But it's always best to have a battery on a hybrid even if it's a small 5kWh
Else go grid tied. 

It's alive. Might make a build post soon. 

I can send you my settings file. I'll try tomorrow. Only about 6 settings that I've changed. 

I have a fast blow fuse as close to the cell + as I can before the bms. Bms is electronic and if electronics fail then the fuse protects against that. I then have a breaker for each battery bank to the busbar. I can disconnect any bank from the busbar if it needs maintenance. 
Breakers easily go over their max but a fuse is fast. 
Fuse is only there to protect against any bms failure.

Can also look into something like Tailscale, run a node on your LAN and that acts as the entry into your network from outside. No need to forward any ports etc

I am getting wayyy too old to solder 🤣 that dam crystal pins are soooo small.
Anyway followed the steps on the github page connected everything up to my JK BMS and Sunsynk5k inverter and BOOM it works as described.

I currently use this:

But if I could get a free website I would transition to this:

Or if you dont mind paying something use NabuCasa which is the official one.

It is not safe, but it should work... I'd say, time to implement a firewall with openvpn as an option, that you then use for this...
