Very nice! I really like my Victron setup.

Nicely done! How does this work if you have 2 or more batteries in parallel?

Whatever DB size was specified, make it bigger! This is the new DB I installed in the garage and I completely filled it up with the various breakers/changeover switches.

Completed the assembly of the Renusol TS+ components and installed/wired the panels on Saturday/night. Will post a photo of the solar panels on the mounting hardware. Updated the firmware of the Smartsolar 450/100 and we were good to go. I ran out of sprag over the weekend so I still need to tidy up the cabling to the MPPT and the batteries. I also need to redo the DC cabling from the Inverters to the busbar as they are not all the same length and the inverter with the shortest cable is working the hardest. Here are the stats for today. Overall I'm very happy with the outcome.

The solar side is no where near completion but I wanted to get the inverter and batteries online so I can give the middle finger to loadshedding. Connected all the inverters together with the cable I made, fired up the laptop and connected the MK3 interface to the VE.BUS port of the left inverter which will be the master, the other 2 will be slaves. The VE.Bus Quick Configure tool makes it very easy to setup a parallel or 3 phase system. They all have to be of the same type and firmware version. I had to update my master to the latest firmware and it was good to go. Did some basic config using VEConfig and BAM, we are online on VRM! Looking at these load figures I seriously need to pull my finger out and get the solar panels up and running. I'm keeping City Power afloat all by my self!

Finished making all the DC cables. I simply could not get the 75mm cable to fit in the top busbar enclosure so I resorted to 2 x 50mm. I have a severe disliking in working with anything over 6mm! 🤣 Finally complete!

Thanks. I like to do things the right way the first time, and it gives you a great sense of satisfaction when you stand back and admire your work.

Mounted the third inverter last night and started with the wiring. Wil be adding a separate earthing wire for the cases tonight. Started with the battery wiring as well. Couldn't find red cable so blue will have to do. Each inverter and solar controller battery wiring is 25mm. I will be running either a single 75mm or 2 x 50mm cables from the busbars to the KETO disconnect.

Added the Carlo Gavazzi ET112 and some indicator lights so I can see what the grid/outputs are doing. These are not the final installation locations, I just needed to mount them so I can see how much space I have left in the DB.

Spent sometime last night installing the 2 busbar enclosures, KETO disconnect and batteries. Left some space on the right hand side for 2 additional batteries. Also started with mounting the brackets for the solar panels. I still need to set the angles and mount the rails. There will be 2 rows of 14 panels each. The purlins are not in line hence the kink you can see half way down.

There will be 2 busbars per enclosure. One enclosure above the battery disconnect and one below. The batteries will connect the busbars at the bottom and the inverters/MPPT controllers to the top one.

Wiring of the DB started. Stated with the installation of the trunking. The OBO stuff from O-line is really nice to work with. Big thanks to @HiTech for pointing me in the right direction. Still have to the enclosures with the busbars, KETO disconnect and the bottom trunking for the batteries.

Work has been keeping me busy, so progress has been slow. Made some busbars for the batteries and other equipment to connect to.

Yes, I couldn't mount the new equipment on a wall looking like that! My OCD will drive me up the wall!

This weekend was spent cleaning out the garage and prepping the wall for installation. From this.. To this You can see the space I left for the 3rd Multiplus. Now I have to hang the batteries and install the trunking. I also need to pull 2 x 25mm SWA cables tp pickup the feed coming from the DB in the street.

I did consider using a single unit, but that also gives you a single point of failure. With 3 x 48/5000 units I get a higher charge current, higher AC transfer as well as a higher output on AC2. There are no downsides to using 3 units. Also, the 48/5000 unit is the only one you can parallel, not the 48/8000 or 48/10000.

I posted a thread a while ago about the advantages of Victron over Sunsynk and vice versa. Everyone was telling me to go with Sunsynk. Well, seeing that I like to be different I went with a Victron solution. We use Victron equipment at work so I sort of know my way around it already. I will split the install over 2 phases. Phase 1 has been ordered and delivered. Seeing as this is a DIY install it will take me a couple of weeks to install everything. My work will be checked by a qualified electrician and COC issued. I plan on running 2 strings of 7 panels to the MPPT RS. My roof is flat so I will use Renusol TS+ components to lift the panels to achieve 30-35deg. I'm still debating whether to mount them in portrait or landscape mode. I'm leaning towards portrait as it means I can have 1 row of 14 panels with a second row of 14 behind it. otherwise I will have 4 rows of 7. Phase 1: 2 x Victron Multiplus II 48/5000 1 x Victron SmartSolar MPPT RS 450/100 1 x Victron Cerbo 1 x Carlo Gavazzi ET112 2 x Hubble AM2 5.5kWh batteries 14 x JA 460W panels DB boards, busbars, KETO1 battery disconnects, cabling etc. Phase 2: (add to system in 2 months) 1 x Victron Multiplus II 48/5000 1 x Victron SmartSolar MPPT RS 450/100 2 x Hubble AM2 5.5kWh batteries 14 x JA 460W panels Once phase 2 is complete I should have enough batteries and panels to be almost totally off-grid. I will post some photos and status updates as I go along.

I also got caught out by this! 🤣

Did you change the address dip switches on the Freedomwon? The first one should be up and the rest down.

Thanks for all the replies. It looks like it will be Sunsynk then.

Why do you say that?

First post here. This is not about which one is better, but I want to know if the Sunsynk has other advantages besides a built-in MPPT controller? Why would you choose it over a Victron Multiplus II and a seperate MPPT controller. I know cost is a factor but lets only look at features.
