For pure off-grid use (no connection to grid), I’m evaluating the different inverter architectures I am seeing and interested in any insights as to pros and cons of each and reasons to prefer one architecture over another:
LF: Conext SW is a good example of this architecture
2xHF (Split-phase): I’m sure there are a bunch of these but will choose the new EG4 6000EX as a good example of this architecture
Single-phase HF + AT: for a true off-grid setup, the AT would always be connected to no screwing around with switching it in and out or switching neutral-ground bond. There are too many 230/240VAC single-phase inverters to name but one of the many options from Growatt is probably as good as an example as any.
For simplicity, cost, and weight, the 2xHF split-phase inverters are very appealing so I’m interested to understand what drawbacks they may have versus the other two architectures…
