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

Thanks for that info Pink

From Inverter manual: WARNING: Because this inverter is non-isolated, only three types of PV modules are acceptable: single crystalline and poly crystalline with class A-rated and CIGS modules. To avoid any malfunction, do not connect any PV modules with possible current leakage to the inverter. For example, grounded PV modules will cause current leakage to the inverter. When using CIGS modules, please be sure NO grounding. Means ? Pink

Any one have some good suggestions for this parts? Price vice Im looking for something midrange i guess. 2 x 600VDC/30A circuit breaker 2 surge protection 1 x AC breaker (32A?) Pink

regarding: surge/lightning protection: I have 2 serial strings so i guess i need 1 unit per string then?

Here is a nice deal from same company Pink

what wire u suggest for serial string panels? Pink

Thanks for the input. what i estimated was production/hour ( watthour) to see what would be capacity left for charge batteries. Pink
