    Blue sea has some chargers targeted specifically at boats: https://www.bluesea.com/products/category/30/USB_Chargers I have my eye on this industrial charger for offgrid use: https://www.coolgear.com/product/usb-power-delivery-60w-high-power-industrial-adapter-charger-ccg3pa

    How many watts does the growatt use in power saving mode? I will also need to avoid the vampire drain. Turning the inverter off with the switch seems like another option.

    It looks a lot like the remote port on an AIMS inverter, which could turn it on and off by shorting 2 of the pins, and the other 2 pins were for power and fault LEDs. Might be something simple like that.
  • Post in thread: Epever is money down the drain.

    They have an 'IT' series now that's like 'BN' with the fins, but goes to 60A. I have only found it for sale on Alibaba so far. https://www.epever.com/product/itracer-60a-mppt-charge-controller/ BTW, the other reason to prefer BN or IT is that it supports way more overpaneling than AN.
