Wife asked me today how much our solar system costed all in all, becouse a neighbor had commented that we must have been using B20-30k or something on this. Wifi only smiled and told here its way more than that. I just updated my spread sheet and I just rounded B300k for all, lets say its 310K when completed. I created a separate tread for the battery build of this project here. Pink

I will be use shrink tube on all connectors. The front Im plan to use clear acrylic sheet. I want visibility to easy see all ok. Pink

Good points Crossy. I was considering using some white ceiling boards/plates i have from build home, but i might get something stronger then. I plan to isolate all steel with 3mm EVE foam glued on the steel. Pink

Is time to get the batteries for my DIY solar project built. There will be 2 batteries with 16 EVE LF280k and a JK 150A BMS on each battery. The LiFePO4 will be placed with the largest side down, not standing up. The rack is made and up now, its made for some airflow and for compression. I will also use some 3mm EVE foam between the cells. and also to cover some steel. Pink

We was testing the voltage after adding each of the 7 panels. My setup is 2x (7x2 in parallel), got around 280v on each test. All went smooth on the first side of the roof, then on the other side i guess the heat and the stress affected me a moment, i sent up the parallel connectors connected on wrong cable and the wrong way. After a short time out i found my problem and corrected it fast and easy. Next now is cabling of the solar power to the inverters and making building the battery. Pink

Today i got the 28 panels up. Quite hot weather for this type work..I had a family team helping me, the mounting it self was done today. Pink

Im not sure Im so worried. I just shared my solution for grounding my diy solar rails, then hopefully it will be a ok grounding. Instead of connect all the rails together, i guess the roofing and steel work already connect them. Pink

Im mounting panels on a metal roof who is build on a steel construction In top of blocks and cement poles, with DIY solar rails of steel. I then got the idea to connect the steel roof or the garage steel construction to a Ground rod, will that work? Pink

I have re read inverter manual to see if i missed any info but i cant find any details there on bust routine for on and off. So if i understood correct: Pre-charge On battery breaker On mains breaker On solar breaker(s) Turn ON inverter For close : Off inverter first, then reverse order listed? There IS some progress here and more updates and photos will come soon in the solar project tread. Pink

"Close" = "ON", "Open" = "OFF" : I would never guessed it. thanks for clarification. Do you have some good routines or rules for order to On ( i almost write OPEN) and off all: solar power, Battery breakers, bms, inverters. My guess would be connect solar power, power on BMS, precharge and On batteries, then On inverters. Pink

Led was good idea, what led to use? Can you explain close the breaker. Not precharge and open breaker to connect battery to inverter? Pink

Pink My main is is to place button and resistor on both breakers/wires going to Inverters, then I just thinking that by pressing one button will recharge both inverters right since they are paralleled before the breaker? (Its no problem it that, just want to be sure how its working) Pink

I have buy parts and prepare to set up Push Button Pre-Charger On my 2 Inverters With Parallel Battery. The batteries are parallel connected between breaker and inverter. So i asking my self if enable the ONE pre charger if it will precharge both? Here is a plan i found ( my data is different from the example img) But i plan to connect it same way. Pink

Latest changes done and now its working, connecting all L ports in top was the key. Thanks to all who contributed. Pink 334166303_6310060529058176_39950617100528018_n.mp4

Ok, i will re wire all and also be sure use 3 pole connectors so all connect correctly. Update will come later Pink

Tested it now after change the wiring with no changes. My testing is with 2 pole connector so how it connect N to what house power wire is random.

Tested, no action Pink

Ok i will test that, thanks Pink

I see some other ATS connect to those green connectors: example Pink

Here it is Pink

ok, where i find that? Pink

Here is details from the top part. Pink

I have no manual. There is some info on lazada. Pink

Today im testing out the ATS before prepare to mount it up. I connected 2 wires to house grid power as 2 power sources and outpower to a light. All working when turn switch myself but there is no auto switch happening. When i remove the active power source it just close the light. Any ideas whats wrong? Auto/manual option is set to auto.

I did notice that, thanks, yes its typo. I have requested it to be edited if possible. Pink
