Okay cool, going to give this a stab!

Thank you, hmmm, where do I Set "grid charge Point 1" to 50%?

Hi There, I need your assistance please, I would like to set an automation for my Inverter but im sturggling to figure it out: Sunsynk Inverter Automation: If scheduled outage in 60 mins Then Charge battery to 50% Thats it, to ensure I have atleast 50% Battery Charge before load shedding kicks in. Thank you!

Hi all, I need some assistance please, I have. SS 12kw 3Ph inverter with 2 x SS 10.65ke batteries. The one battery was installed recently. Both batteries have the latest FW installed for their specs, but they run on different versions as one is much newer. The installer is struggling to get the newer battery to talk with the inverter, is there a way or method that needs to be used to get the new battery to be the Master and talk to the inverter? The old battery cannot be master due to the older FW version. Any help appreciated. Thank you

Meant to quote on reply.

Hey there, I just wanted to find out if you managed to sort this out with ethekwini? Thank you

Hey, just started getting this, any definitive fixes?

Hi, I'm interested

Im just not sure why, maybe Amperage, but you would reach VOC limit and not maximise wattage.

Yup the 550w makes sense if you need 2 strings, because of the Amperage limite, and maybe panel layout is important agreed. If not -in my case - one string of 12 x 660w is better, just not sure if there is a negative to having these panels.

Hi All, Will be installing a Sunsynk 12kw 3 Ph (through a certified Installer). I am trying understand why most solar installers like to use the JA 550W panel as opposed to the CS 660W panel? I could put 12 x CS 660w Panels which would be the max wattage rating of the mppt at peak production and still be within the 25A threshold, vs 550W panels which require more space and installation to achieve the same Wattage and ultimately limited by VOC on number of panels. The CS 660W would achieve Wattage threshold before VOC is reached. Am I missing something?

Hey All, So after great help on this forum, I have realised my roofing will not be suitable for solar anels, in summer it will be okay, but winter will be shaded almost all day. I have identified an Awning of mine which can be repurposed for Solar Panels, it will need to be re-enforced or a new structure put up. Does anybody have any dimensions or considerations as I get a builder/awning company to come and quote? I am not sure what supporting beams etc might be needed? Looking at 6 x 2 Panels in Portrait Orientation. Would be appreciated.

Haha good idea for Life in general, Although having looked at it, I think redoing the awning is going to be the best solution. Could get 12 panels there and potentially phase 2 is the lower south awning as well. Will get some awning guys to cost It out, won't be able to support as is and angle is incorrect.

That would be cool if you happen to be on this side? Had another look and think my neighbours need to either cut their trees or I need another solution. Will be a waste in winter as the shading will be pretty much all day by my calculations.

In the North, howcome?

You actually gave me a good idea, Why not use the Awning to support the Solar panels (I will prioritize NE on Geyser roof - and sacrifice late summer PV for better winter production) and then as phase 2, get a re-enforced structure for the awning to support solar panels at an angle and use that, I suspect around 12 panels could fit on there. I might approach the one neighbour as well and see if he will be open to the idea of removing one of his rees, on the North of this image, which will help Winter Production. Summer the Sun is pretty high already by then. Really helpful ideas, thank you!

Great App, Im actually pretty much facing North (Not NE, More like NNNE). I see the issue is not so much summer, but Winter, having South panels will be a big waste as in winter angle will be all wrong. This actually works in my favour now, I will have to sacrifice Summer Late afternoon Sunshine for Early Start to production in Summer and good coverage in Winter.

Thank you, much appreciated! Tell me, when you say Ridge is there a way to mount panels on the actual Ridge? Have any pics?

Thank you, appreciated. Neighbours: They are great but due to topography would essentially be asking them to remove trees as I am a level lower. They also serve as privacy for my family and theirs so realistically not an option. When you say NW where are you referring to? Will look into it this afternoon. Also the Ridge you refer to, not sure exactly where you are referring to? I also have 2 small East facing portions which can hold a few panels and will gt early morning sun. However as it gets later in the afternoon, they will be no be ideal. Am I able to connect east and north east on one string? Will this impact performance of NE panels when East is not producing ideal?

Hey all, I'm about to go ahead with my solar system, but am concerned about the direction my solar panels will face. 12kw ss, 550w panels. My roof details below: - Tiled roof about 25 angle on each side - 2 Orientations: 1 side is NE and opposite side is SW - NE Side has space but is impacted by shading due to trees both early morning and late afternoon -SW side has lots of space, is not impacted by the morning or afternoon tree shading Some options I have thought of but really unsure: Option 1: Put 10 Panels on NE and 10 Panels on SW in separate strings, but I'm not sure if SW will produce much, am I wasting money? Option 2: I could put one string of 10 with 5 facing NE and other 5 facing SW to minimise afternoon shading on NE string And another string of 10 facing SW or NE (shading again applies) I am in Durban, so load shedding is minimal, but trying to utilise as much solar generation as possible without heavy investment in batteries until needed. Any advice would be appreciated. Pic attached, orange are trees which are not in my control.

Hoping @Leshencan assist, He seems to be extremely. Knowledgeable on the SS systems!

Hey All, I am hoping the wealth of knowledge on this forum can help me in my decision making. I am not an electrician, but want to make sure I atleast udnerstand to some extent wha im buying) I will be installing back up system to my home and need some guidance on the installation of my system, I am using an accredited certified installer, but wanted clarity as the Sunsynk 12Kw 3Ph (Already purchased inverter) will be the first he does. My question is around 3 areas: 1. Inverter Load on Grid 1.1 what is the maximum safe pass through I can have? Datasheet says 60A. 1.1.1 - is the 60A per Phase? 1.1.2 This applies to when im on grid for essentials only? 1.1.3 If I exceed 60a per phase the inverter will - trip or blowup? This is important as when im on grid, my usage on 1 phase may exceed the 20A limit which is there for off grid (My kitchen appliances if used together , Micro, Kettle and Coffee machine will on their own get to around 6kw). Also my family is growing, and in time, usage will increase, rather than decrease. Installer recommends 20A max for on and off grid as he doesnt to damage the inverter, but that is too limiting when im on grid. 2. Inverter load off grid 2.1 What is the maximum power the inverter can provide safely while off grid, Datasheet says 19.1A, but it also says imbalanced load of 6kw which is more than 19.1A? 2.1.1 If I have a 60A pass through (as point 1 - on grid) the inverter will be able to supply more than the 19.1A Max stated, is there anyway/setting to limit the inverter to not exceed the 19.1A or will I need to manage my load manually? 2.1.2 What happens if I do mistakenly exceed the 19.1A load? This is important because I will manage my load during off grid to stay within 20A, but if by chance I happen to exceed, which can easily happen if people forget its load shedding, I need to know what will happen. This 20A limit is fine ofr off grid, but not on grid where lad will exceed 20A on a single phase. 3. Batteries 3.1 As im in Durban, load shedding is minimal, so plan on having a small battery bank to start (possible 1 x 5.32 or 2 x 5.32) 3.1.1 I will be limited to the battery output here of 100A max discharge , what happens if I exceed it? 4. Solar Panels 4.1 I am confused by the MPPT design here: 4.1.1 Datasheet states PV MPPT range 14v - 800V but Max PV input is 1000V (Is 800 the safe value or Max value?) 4.1.2 is Max PV input of 1000V across both MPPT's combined? 4.1.2 25A MPPT - Does that mean I can have a JA Panel 550w which has an Amperage rating of above 13? and install as many until safe VOC is reached? 4.1.3 Based on above info, I will calculate max panels, as panel Volts are 49,9 per panel Important for setup of Panels as I look to expand, need to start with the right panels so that extending is easy. I really, truly am appreciative of any support, have seem lots of comments on thi on 8kw and 5kw, but not 12kw, and was hoping to get some clarity as im now at wits end of googling. Thank you.

Hi Peter, Thank you and much appreciated for the frank and honest response. You raise some good points that I may not have thought about and need to relook my approach. Can you advise who might be some of the most trusted/reputed solar professionals? Every website I go onto seems to say they are professionals. Will do more reading as well.
