Update: The client decided to simply move the 2nd inverter next to the 1st one along with its batteries to enable parallel mode using data comms. Now, he needs to lay down new wires to connect the PVs from the 2nd inverter original site (250-400 m distance between PVs and inverters/batteries)...
Hello everyone,
After a couple of months of lurking on the forum I've finally decided to register and post a thread about my conventional/boring network engineering project that turned into a nightmare when it overlapped with solar technology. For context, I'm a research physicist who does R&D...
Update: When the second inverter is shutdown and the first is connected to grid it's screen shows this (load supplying the grid, in other words complete nonsense). When both inverters are connected they show F18 AC overcurrent flow fault.
I don't mind the discussion at all, on the contrary it was the reason why I persuaded the client to bite the bullet and transfer the inverters together. Your configuration relies on the utility grid to sync them - an efficient solution if power outages are short and few. When you lose the...
The last statement is a metaphor about bad outcomes and non-zero probabilities. Given enough time their decoupling will happen if their frequencies/phases are not perfectly aligned and if there are fluctuations, those are realistic assumptions in this case.
Thanks for the insight, now it makes sense why they don't have MAC/IP addresses. I was given a CAT7 cable and all that they said was that they need to be straight/not cross-over. They connected the inverters with a single CAT7 cable directly (which didn't work obviously) and then I used my...
