40 meters, on top of garage Pink

I need to order 2 x 100 m solar cable. PV1-F 4 mm ? I found this on shopee. 4mm2 ok? any views on levels of quality/price on solar cables? Pink

Ok maybe i just make a separate ground for the DC surge just outside the wall.. Pink

DC surge ground must goto the same ground i use wit panels? can ac and dc ground be same? could DC surge ground use home ground? Pink

Thanks for useful info om grounding. What type/thickness wire i should use to ground the solar rails and dc surge? Pink

Is there other ground on inverter than the ground port at ac in/out? I expected to connect this ground to the ground in my power panel who is my main ground for home. Pink

Can you explain more? Inverter ac ground i will wire to home ground right? Pink

I have not order yet so i have change to 800v. I will have a diy steel rail on top of garage, i should ground this right? then send surge ground to same? Pink

DC 1000V Surge Protector between solar and inverter need ground wire. Connect to same ground as use for the panel rails? In this drawing its used 1000v fuses is that any good idea? Pink

Its under a large concrete stair with extra room added to it and with almost 3 meter to ceiling at that part of the room and built with qblocks and concrete so both space and temperature is fine. Pink

Will it work to stack the batteries with poles up? 8 batteries +8 in the top? Pink

Good idea, how wide is the space between the 2 walls? Where you place the BMS? Pink

Currently planning the setup in a room i have under my stair. I have a 20cm+ wide place behind my door i want to use for batteries. As i see Calb batteries are 18 cm wide so that would fit perfect as i can see it. Is there any problem to build a 16 battery long, (1 row only) and get the MBS to all batteries? If so are there longer wires or can they be extended? Pink

Thanks for great info BritManToo. Little by little im soon ready to get this up. Pink

What dimension do you have for your battery cables? Did you make them or buy them ready? Pink

Thanks for that i will check it out,, looks quite heavy duty.. Pink

Are you able to share some link to lazada or shopee with some options who can be used? Pink

I try order all from same shop. i had problem to find much 600vdc at Lazada and shopee so i found this shop/brand on aliexpress. Will the one of this do the job? Or this one? Pink

And this? Pink

Great, who of the 3 would you choose? Pink

Ok, the one i posted earlier is ok?

Ok, can you show example of what i need to buy for that? Pink

Thanks for the info. Your setup is connected to grid? My manual want breaker and surge protection on the IN power sources, grid and pw. Pink

This one ok for ac? Pink

There is 2 single serial strings who have its own pw port on inverter. So i will use a dc breaker and dc surge/lightning protector between panels and inverter. AC anti surge/lightning protector i should use for grip power before inverter? Pink
