I’ve got two these 1kW GTIL inverters powered by a 560Ah 24V LiFePO4 battery offsetting consumption daily (one per leg): https://www.amazon.com/Inverter-Lim...ocphy=9032080&hvtargid=pla-523294429130&psc=1
I’m happy with how everything is working except for two nits:
-when maxed out, the fans kick on and they are pretty loud (so if I can reduce the frequency with which the inverters max out, it should quiet things down and should extend lifetime to boot).
-because my 120V load is often unbalanced, the GTIL on one leg will often max out while the the one on the other leg is hardly being utilized (so I am leaving as much as 50% of the potential self-consumption-offset on the table).
For these reasons, I’ve been mulling tracking down the offending loads and better-balancing by swapping some to the other leg in the breaker panel, but that is enough of a PITA that I’ve been looking into the possibility of adding an Autotransformer to balance load instead.
Connecting a 25A Autotransformer such as that offered by SolarEdge to a new dedicated 25A dual-pole circuit should allow as much as 3kW of imbalance to be rebalanced: https://www.amazon.com/SolarEdge-SEAUTO-TX-5000-StorEdge-5kVA-Auto-Transformer/dp/B07KMDMXBR
So I’m considering investing $400-600 in a TX-5000 but also wondering whether the same thing could be accomplished with one of these 5kW 120/240V transformers: https://www.amazon.com/gp/aw/d/B00J0CF8W4/ref=psdcmw_10967761_t1_B083TG3GMG
Efficiency may not be as good as the SolarEdge, but at less than half the price, it’s worth asking about. And since that transformer is fused, it can be connected to an existing circuit without needing to add a new breaker.
Is there any reason that connecting L1/L2 to the 240V input and Neutral to the neutral prong of the 110V output will not deliver equivalent balance function as to what the SolarEdge Autotransformer performs?
