Posted December 4, 20213 yr We all like show and tell, right? So creating my placeholder for my install that will be taking place over the coming weeks/months. Planned Equipment: SunSynk 5kW Hubble AM-2 5.5 12x 455W JA Solar in 2 strings Looking forward to sharing the build and running of the implementation over the next period.

And 2 of the panels that arrived broken - so they were returned before the courier could offload them. It has been three weeks now. So hopefully soon those pieces will arrive.

Finally got the panels onto the roof. 3 more to go for array 2

Finally the last 2 panels arrived today. Tomorrow they will go up to complete PV2.
December 15, 20213 yr Author Got to get some work done today - the beauty of holiday projects and holidays. Now that both PV Arrays are wired up to the DC Distribution, getting the inverter and other isolators and things onto the wall ready for wiring. Layout drawn onto wall for spacing and placement of component Inverter Mounting Bracket onto the Wall PV DC Termination from Panels, ready and waiting for some feeds and cabling Will get some more progress pictures going as this project progresses.
December 23, 20213 yr Author Just some update on the wiring progress. Panels are wired to DC DBs and connected onto inverter. Some wiring still in progress. Update: See post below on wire type for bridging DC breakers and comment regarding safety of the fuse holders ito wiring direction and regulations. Edited December 24, 20213 yr by StickeyTape

December 24, 20213 yr It's ideal to supply your fuse holders from the top so the fuse will be dead when removing it for whatever reason. If you supply it from the bottom, it remains live even when the holder is opened

If you supply it from the bottom, it remains live even when the holder is opened It also is against SANS regs. Line at the top, load at the bottom unless clearly labelled
December 24, 20213 yr Author Implemented the guidance from @Leshen and @phoenix752 regarding the DC wiring and fuses, top down feeds and using PV cable for the loops. Thanks guys, appreciated. Edited December 24, 20213 yr by StickeyTape

Quick question: did you take the conduit going to the plug in consideration when you drilled the holes for the base plate or were you "lucky" or does the supply come from a other side?

Haha that's good to know, I once drilled a hole through a conduit on purpose, so that I didn't have to chase a wall. I just had to "fish" for the wires through the hole into the conduit and did the connections inside the switch's box.
January 4, 20223 yr Great build, @StickeyTape. How many kWh is this system expected to produce annually?
January 8, 20223 yr Author My battery arrived this week. Oh boy what a breeze to get the Hubble AM-2 installed configured and BMS talking to the Sunsynk. This baby is about to get his first charge up. Looks like a nice full sunny day. Then start setting up the Work Mode settings to match our home usage profile.

I have 2 of these Hubbles and also was super easy to Config. Have never seen the battery temp go above 28 degrees.

As the inverter reports production in the context of use. Ie. It might be able to produce more, but if there is no use/load for it then it tones itself down. Im not exporting to grid. Ive gone from about 25 units average per day grid to about 5 to 7 units per day before I installed the batery. Will know in a week or so if the battery made more grid reduction improvement.

True that, but if you are like some of us, you may find that your usage actually increases, because you can now afford it 😁 My own usage went from just over 300kWh per month to 380, and in the past year in total I bought only 196kWh from Eskom, a reduction of 96.4%. I think that what @Bataleon was referring to was the potential yield. Here is is great tool, with my own potential yield is 6.757MWh per year. https://globalsolaratlas.info/detail?c=-25.978763,28.061957,15&s=-25.992227,28.061914&m=site&pv=small,185,26,6

Below some sample real measurements of my install for this month. NOTES: Battery was only installed on 6th. Most of the grid is from my old 3kW inefficient geyser in the morning before the sun comes up. (my next project then that geyser dies) plus about 300W - 500W odd feed off grid in the morning hours after the battery runs to 40% SOC. [have not done SOC lower than 40% yet] plus the odd days when my tenant decides to cook up a storm in the flat 😞
