So if I understand correctly the AC input to the Smart load devices will not be Eskom but come through from this Gen port. I was thinking the changeover switch is a good idea incase the inverter has issues I can use the changeover to feed the geyser directly from Eskom bypassing the Inverter...

I now understand how it works.. Only question now is how would a typical wiring look like?

Does inverse also apply.. Switch on when grid is not present however PV is there and battery SOC trigger level is met

Wow.. Thats interesting indeed..will need to do more reading on this port..

So this means if there is no PV being generated (rain or cloudy day) I will not be able to heat the Geyser using Eskom?

Hello, I was told I can use the smart input of the Deye to heat up the geyser using PV. My understanding of how it works: When the batteries reach a certain % then the smart input is triggered even though there is no Eskom As long as there is sufficient PV to heat the geyser the power can be consumed. Question: Does the geyser have to be connected at essential when using the smart input? What happens during normal functioning whereby there is Eskom and wish to use this input to heat the geyser? Thank you for your input...

Sorry Guys, do not understand the terminology 5S1P, 6S1P etc...

Is this 425/450v per mppt or for both? I wanted to put 9 panels.. 4 East on 1 mppt and 5 North on another.. VOC is 49.4v which is total of 444V total or 247v on one mppt and 197V on other.. Can this work on a 5kw?

The VOC of the panels is 49.4.. This means that 9 panels would be 444V..is this not too close to the max voltage?

So I now went on the roof and measured etc...This is the final options available to me. North 359 - space for 5 panels NE43 - space for 2 panels E90 - space for 4 panels. I was leaning towards 5 panels in the North and 3 panels on the E side so I get some quick morning charge up of my batteries and after 2/3pm the North side only should run? @Scorp007 @TaliaB Question: Which config would be best? I wanted to put about 8 X 545W panels on a 5kw inverter.

Aha, I will check and advise....

How do I check the degrees you speak of in your comment?

So I went on the roof today to measure to see how many panels I can actually fit. On the North side I can fit 6 panels max On the NE side I can fit about 4 panels Max. So Option A would be 6 panels North Option B - 4 panels North and 4 panels NE. Which option would yield the best?

Hello, I wanted to use the JA 545W on my Deye 5kw which has a VOC of 49.75 and Amp of 13.04. Option A - 8x in series on single MPPT facing North Option B - 4x in series on MPPT 1 facing East and 4x in series on MPPT 2 West. This is JHB.. Question: Which would be better option?

Don't you want your breaker to trip if there is an issue of over drawing.. 32A is 7kw and 40A is 8.8kw..

My installer put 40A on my 5kw..must I replace with 32A?

So what then is the limit for the non essential whilst on Eskom?

But there is limit on the essential side whilst there is eskom? So you are saying the inverter will display essentials (max 5kw) plus max essential? What would happen if you exceed the Eskom essential side?

Hello.. Quick question.. You have PV and do you have an auto changeover switch for eskom/inverter source?

Hello.. Something strange is happening with my Deye 5kw inverter. Eskom is present so not in UPS mode, I don't have panels. If I exceed the Amps on my essential circuit the battery starts feeding the load? Is this normal? My understanding if there is Eskom I can exceed the inverter capacity because the load is fed from Eskom and not battery so the capacity of the inverter does not matter? Please advise?

Just check what is the max wattage the mppt can handle also the VOC of each panel and therein the string. Depending on how many panels you place on each side.. You can run each string connected to one mppt if you have 2 or connected then all together in a single string taking note of the limitations noted above. What inverter you have and how many panels and want to place on each side? You knw the wattage and VOC of each panel?

So I looked at the spec sheet of the Canadian panels. There seems to be 2 specs (Standard test conditions (STC) and Nominal Operating Temp (NMOT), each have different VOC value. Which one do I use for my calculations of my max string?

@Zhann - Set-the-bardid you come right. I also recently purchased the Deye and not happy with the interface on the Inverter. What's different with the Sunsynk logger vs Solarman?

Yep, I wanted to get my total usage per month on both essential and non-essential circuits and wanted it in the app so it's easy to view and track.

So I emailed Deye support. They confirmed if you have essential circuits then you would not see the usage on the Grid Icon nor on the Home icon. Only place you will see it is on the CT value. This is really stupid on one hand as if I want to see if my solar system is really reducing my power usage I need to see total usage(essential as well as non essential) on the inverter icons as well as on the Solarman app(CT values don't count). So if I want to achieve total home usage the only way to achieve this in my opinion is to put entire house on essential side then every usage is shown on the inverter icons as well as on the Solarman app...
