Thanks for that info Bandersnatch. Your inverters is not connected to the grid if i have understood correct? Pink

Hi Bandersnatch. Can you share some info on Inverter and battery capacity vs ability to fully offgrid? Pink

I give them some try now, but for my panels they not fit well and there take much luck to get it in place in a good way, so its not a solution to deal with on top of the roofing, so I guess I'm going with nylon strips then.

I got 80 pieces of this today. They are very firm so i have some issues to get them on my panels who have a lip on the inner side of the frame. But with a plyer and a rubber hammer I'm able to get them on and firm enough to hold ok. The side for cable is almost closed so for ready made cables on the panel there is some struggle to get a cable inside, but i will test with a thin round plyers to open then close it again when cable inside.. So maybe a little extra work but it will also last long.

I have more or less decided for a change in my setup: Since most issues i see regarding Growatt and also other all in one system seems to be related to grid power issues, i will try run my system with grid power only on the ATS. I use 20 units a day, solar capacity 9.5 KW, 26kw battery capacity. So maybe I'm able to run most of the time without grid at all? Pink

Thanks for the clarification Crossy. Pink

What's best practice regarding cable length. Equal length from breakers to batteries and /or equal length cables from breakers to busbar? or to inverters? I'm my plan i expected to be equal on cables within each battery via breaker and to busbar. Then different length from busbar to inverters. but i got confused when watch this video with Will Pink

In the end i would added more money and buyed something more tested. Pink

Same here i have 2 black wires too, the + connectors have a red rubber ring or something.. In my setup i have define a center panel ( panel 4 of the 7 Who i define as a + side and a - side for the added panels. Pink

On my plan for the panels placement and connection i have 4 x 7 panels, So lets say panel 4 have 3 panels connected to its future minus then those cables will get black when any extension needed. The panels connected from future plus on panel 4 get red wire when extension needed. so then i end up with correct colors /polarity before parallel and extend them to inverter. Pink

Instead of bolting up some busbar on the wall i was thinking of doing it this way: There is 2 red cables from DC breaker and 2 red cables going to inverter so my plan was to bolt the 2 cables from DC breaker in the one end of copper bar then bolting the 2 cables to inverter in the other side of the bar then shrink tubing around it so its just a part of the wire from A to B. Same for black. Any issues or problem with this solution? Pink

Just made my first MC4 solar cable.. watched YouTube instruction when making it and it come out quite ok. I need to use 2 sets of MC4 tools because LINK * the company) use the black tool and the Panels the orange tool. Its different in the way the pins attach the mc4. Pink

I have 2 x Tomz 2P DC MCB 600V 125A  Circuit breaker FOR PV System Pink

150A? Can you suggest any Class-T fuse Pink

So i planning for 2 x 16x280a lifepo4 batteries with 2P DC MCB 600V 125A Circuit breaker on each battery. The cables will be paralleled between breaker and Growatt inverters. Should i add any fuse to the plan? Its no fuse mention in the Growatt manual. Pink

A smaller DIY without battery just sized to get the needed sun power in day time can be very cost effective and very fast ROi like in your case. I suggest that for people here who ask me about solar and budget. Do you have a link to your solar build tread? Pink

Its very true. Its like the top selling brand cars, there will always be some issues, and with huge sales volume there need to be some issues. Pink

Look like a very cost and time saving construction, well done 007 RED. Pink

scary.. I do consider not ad Grid in to my setup.. Is there any other source than Youtube on this? Pink

For this project i would have hired some with experience. not the easies roof to work on and since its a few panels only i think best use of time, money and the possibility of any issues. A good professional will get up those panels in a few hours in a good secure way. Pink

Let me also ad that the best way to get better sellers in the market is to find and reward the fair sellers with orders and good feedback, and let the less fair seller not get our orders and to pay for their actions. Pink

Had it been a hammer i had probably let it pas, but a cutting tool not ok for me. I had more issues like this who i know i got a returned used product but let it pas, but on some items its not ok. Its not to much to expect to get a new unused when payed for that.. The seller know when they do and speculate that most will think its ok.. I must admit the pickup option on return is a big plus. If i has to bring it any place myself i had probably not cared to do it. Pink

Yesterday i got my cable cutter plier from Lazada. I got a unit that obviously was already opened and used before so either some get what they need done with it and sent back or just dont like it by any reason. I asked the seller why he think i want to pay full price for a product and get something second hand. I got no reply, return is under process. Not that it could not be usable but i need to be sure i get a sharp good tool. They could have cut nails with this for all i know.. PS I got it exactly as on the photo.. i did not need to open it. Plastic in bottom was also sliced open. Pink

Thanks for the link.. Here is another option sold at B5 per piece: https://www.lazada.co.th/products/bec-hq-cc01cable-clip-thunelectric-sss-i2443058466-s8465152005.html Pink

That look like a good option.. If i understand correct the can be placed anywhere on the frame.. Pink
