Specifically, when plugged into 60hz US shore power, I would like the system to only charge the batteries and not feed the AC power for the boat. I would like the AC to continue to be provided by the inverter, which generates 50hz (220v) power. Is this configurable/adjustable? It would operate as a charger for the large house bank at the same time it is an inverter to feed the AC side of the vessel.
No that's not possible. It is either a charger (with the bypass relay closed), or it is an inverter at the rated Voltage and frequency (with the bypass relay open).
You see, the power can only flow in one direction at a time with the circuitry performing either a rectifier function or an inverter function.
Unfortunately, the only way to overcome your problem is to have a separate charger and an inverter.
Thanks for getting me that answer -
Interesting idea maybe - there are thousands of threads of thousands of sailors who struggle with managing the different AC power frequencies when traveling globally.
If you could develop an inverter/charger that would manage both (via a switch?) it would be a game changer for the industry. We only face it when plugged in, but when we do that it is a real problem. Probably sell a lot of these...
Thanks again - back to the drawing board for now
