Integrate Bluetti/Powerbank

[DDean]

Hi All - wondering if anyone has done this already

I’d like to have an out-of-the-way solution to connect my boat to my Bluetti via shore power. I’d like the Bluetti to be secured in the cave and have it connect to the boat via shore power without having cables all over the cockpit etc. 2025 R29 NW.

There’s a wooden back to the cave that I can probably bring a shore power cable into the storage under the aft steering, and then I can install a port on the storage door to bring the cable out and over to the shore power plug. Any other ideas?

Has anyone installed a second shore power plug in the cave? Where would the best place to input that to?

There are two goals: 1) charge house batteries from the Bluetti as needed, but 2) also run AC items as if on shore power.

I’m going to install a big solar panel to keep house topped up but would be good to know what others have done.

Thanks - these new power banks have the potential to be very helpful.

How many watts does the power bank put out?

2600W and it’s ~2100 WH. So it’ll recharge an R29 NW from about 50% (the lower limit of usable power capacity) about once (2100WH/12V=~175AH) and it’ll have enough juice to run coffeemakers etc while being used as shore power.

The trick is to hook it up without anything being in the way!

I don't know anything about the circuitry on the 29. But 2600W is just over 20A. Really no need to feed it into the shore power connection. Depending on how often you plan to use it you could simply make a double ended chord and back feed your AC circuits through a receptacle. Or wire it directly to the input side of your battery charger, let it continuously keep the batteries charged, and rely on your inverter(assuming you have one) when you want to use AC appliances. Not the most efficient way to go but is simple.

I considered going that route(i.e. power bank) but once I took a good look it didn't cost much more to convert my house bank to LFP. We don't use AC power while afloat.
