July 2, 20223 yr So after lots of research on this forum and a crazy amount of help supplied by the members from the forum I am finally on my way with my install. equipment used: 1x 8kw sunsynk inverter 3 x 5.12kw sunsynk SSLB1 batteries 16 x Jinko 545watt panels(S&W says18 is to much) 1 x Merson 160amp battery disconnect with 160amp fuses. OBO trunking and fittings from o-line, will be using 25mm sunsynk battery cables doubled up to the battery disconnect, 35mm cable from the battery disconnect to the inverter. 90% of my switchgear will be Onesto from MCE. special thanks to @WannabeSolarSparkyfor providing me with a great amount of information regarding this install. Because I am only one man doing this install it will take a couple of weeks so I’ll post progression pictures as I go along. I’ll also be able to answer any questions but MOST of all I would like any criticism or advise from all the experts on how or what I could do to better the install. panels and dc electrics will come in the following 2 weeks or so thanks gentlemen!

Either way I now have a very clear picture to the end. Will keep posting updates 👍🏼
July 3, 20223 yr Author @Steve87, @YellowTapemeasure, @Tariq, thank you for all your encouraging comments!

My picture was also very clear.More than once and it’s out of focus again. 😁 Adding a voltage gage here ,changing a cable there.Adding a bit of solar panels extra for winter.🥶 My oh my ,how I love fiddling.😛 Take your time and enjoy the new hobby🤪
July 3, 20223 yr Author @Piper well I was hoping this exercise would be similar to building my crypto mining rig, built every, fiddled for a month or so to get it running at its most efficient state and now I only look at it once it awhile. It’s just works! But I’ll take your word for it and of many others that this isn’t going to be a once off and forget. I’ll check back in at 6 months if I’m still fiddling 😂
July 8, 20223 yr Author Slowly coming together, it’s tough to work at night when my load shedding is at the exact times I can work.

July 16, 20223 yr Author And I’m up and running… we’ll sort of😀 having problems with my batteries syncing with the inverter. So I disconnect all of them and only connect one so I can work out wiring and communications problems. Anyway after stressing my nuts off for awhile I did get the one battery communicating correctly, simulated a power cut and everything seems to be working good. Got my earth/neutral bonding sorted, battery charges from grid correctly. Only running it as a ups for now because I don’t have my panels installed (Next weekends job). CT coil reading correctly I think, it displays positive values. one thing that was causing a problem was my prepaid meter, it’s the one you plug in the wall. For some reason it would not communicate with the outside meter. Was showing error 30.. anyway I ran to the front of my property where there is a plug point, connected the meter, it read correctly, ran back to my house and plugged it in, seems to be fine now but I’ll have to monitor that. Excuse the battery cable laying around at the bottom. Still have to work out the communication. And get a longer CAN cable.
July 17, 20223 yr Author So I got all the communication sorted out. Turns out I had the wrong cables, anyway the correct cables I had were to short so I made a new longer Can cable and also made new communication cables between the the batteries. I don’t really know why sunsynk sell wall mount brackets for the batteries but don’t supply long enough cables to connect everything. I had to custom make all the battery cables and communication cables.
