I have only highlighted the MPPT voltage, as the cable cost is a "hidden cost" between the Goodwe and Victron comparison. I agree, for shorter cables lengths and smaller system this will be less of a concern. Here is my comparison between the two so far. I might add items to the list as I continuing with my research Goodwe Pros: Price Easy of use Single box High MPPT voltage (In my case I can get away with a single string, 15m between PV and MPPT) Cons: Limited flexibility Cannot stack / scale system Complete system, cannot replace parts individually Victron Pros: Very flexible with relays, therefor increasing the system efficiency Separated system, can replace a single component in case of failure (for ex MPPT) Can scale system (start small and add inverters / MPPT etc). Might help with opportunity cost. Cons: Price Lower MPPT voltage (I will have to use 4 strings, 15m between PV and MPPT) Might take longer to configure

I really like the very high MPPT voltage of the Goodwe. I will have to use much thicker cable / multiple cables with the Victron.

Thank you for the responses so far. Are you comparing the Goodwe 5048D-ES with the Victron Easysolar 48/5000? The Goodwe is about R29000 and the Victron Easysolar 5000 is R44000 incl, so it is about 50% more expensive. I have seen the Victron easysolar 3000 going for R27000 so it is actually cheaper than the Goodwe Are there better prices on the Victron? I am an embedded developer / electronic engineer, so I like to tinker with technology. The more flexibility the better for me 😁 This is a very nice feature of the Victron. the 5048ES does not require Eskom to power up I have also heard on another forum that the 5048D-ES needs Eskom to boot up. Is there maybe a firmware difference between the different generations of the inverter? I am definitely leaning towards the Victron at this point in time. Will have a better idea (hopefully) towards the end of this week.

We have recently moved into our new house in Randburg, and I would like to go as much as possible off-grid, but keep the grid as back-up. We are currently consuming about 10kWh / day, and that includes a 150L electric geyser. The geyser will be converted to solar (still deciding on which technology) within the next couple of weeks. We will be adding a small pool (450W / 4-6h per day) and a koi pond (200w / 24h per day) in the near future. Initially I wanted to install a Goodwe 5048D-ES, but after reading a couple of threads on this forum I am also considering a Victron. Which Victron is comparable to the Goodwe? What would the cost difference be between Goodwe and Victron (I dont need a second MPPT at this point in time). I am convinced that Lithium batteries are the future. Currently looking at the Leoch 4.8kWh as I can get this at a very good price. Are these batteries compatible with Goodwe / Victron? Or should I rather look at Pylontech or another brand? I would like to install a hybrid system. I currently have 12x 250W panels that I have removed from the old house, still in a very good condition. I would appreciate any feedback as it is quite a big investment.
