The Victron inverters work well with Fornius inverters , instead of replacing the Fornius I'd look at getting a Multiplus II , maybe a 5Kva which you can parallel up or with 3 units configure into a 3phase connection. And some very knowledgeable Victron people here.

Let's be real here, can you imagine the bickering that would go with sharing solar with your neighbours. No you ran your aircon more , no you ran your tumble dryer to many times, etc.

I'd look at dropping probably 2/3 of the height of the tank below the ground it will make it easier for the return of the water from your grow beds.

The basic sonof switch as far as I remember switches 220v through a single pole relay, the issue is the water solenoid runs of 24v . You will have to tinker a bit more with the sonof switch or get one that has a set of contacts that don't switch through the supply voltage of 220v

For the fish tank depending on how big you need it to be , about 1000l I would use an IBC tote if its larger volume use a pond liner and either dig a hole in the ground or use welded mesh as a cylindrical frame. Your grow beds, what type did you have in mind? Deep water or flood and drain. If its deep water you can use the same pond liner , if you use gravel as a grow media that can damage the liner. Do you have enough space to put the system in a tunnel, to keep the fish tank water warm enough in winter? Have fun , it's quite rewarding when it all comes together

Well when the lights go out, sods law has it at about meal time. If you want to mitigate the hunger of load shedding put a gas stove in . Get a few rechargeable lanterns, at least then you can read a book after a hot meal. Or get some earplugs and a generator, possibly a good short term solution on a budget. Even those aren't cheap But if you miss things like WIFI and a TV maybe a hairdryer, then dig deep it could cost a heap of cash to go solar. If off grid is what's required then that's a whole different budget which will have an on going cost. Certainly the DIY part can save you a fair bit assuming you are willing and able. Don't forget the school fees, cause mistakes are costly. This forum is a fantastic source for information. So " I just want to have a few lights and maybe the tv too" is a tricky thing to put a price on

If your inverter can supply 58v and even a bit more (for a 14s) then you can but I'd recommend a BMS like batrium, Orion etc . In fact pretty much like the above post.

Hey they are both blue so should be a good swop

Wot no separate holes for the neutrals.. looks neat ,like the idea of hinges.

The sizes on DIN and SAMIT breakers are different which is why you have gaps and they don't seem to fit like they should. The ones you are using have a universal rail fitting to fit either type, but they are a DIN rail size switch sot hey fit DIN rail boards better . I prefer to use the Schneider switches .

48v setup will lead to doing you bit to stimulate the economy by spending a heap of your hard earned cash , 😉 But honestly I cant think of a good reason. Maybe 2 strings of batteries instead of 3 . I'd just go for it and see how it works.

Change it to 48v............

Is it a stand alone , if you're running fibre to it can you run power? is the solar for backup or the main power source? I'm assuming one pole with 3 cameras. How many days of autonomy do you need? And the range of the wifi link, is it line of sight?

I've had water temp down to 9°C and the fish were a bit sluggish but fine. I have to agree, insulate the tank and erect a tunnel over it .

I'm with you get a yacht
