Re: Lifepo4 Batteries
Why don't we start now? Make that link a sticky in the electrical/battery section with an appropriate title.

Re: Lifepo4 Batteries
I am looking to purchase a Bluetti AC300 (3kW Inverter) with 1 BS300 (3072Wh Battery). This would allow my 120V 30A shore power to pass thru. When not on shore power the Bluetti will provide my 120V. My second 120V 30A shore power is for Air Conditioning and will stay separate.
Your thoughts.

Re: Lifepo4 Batteries
Also consider how you're going to recharge it, especially if you need to recharge on the boat, rather than via shore power. 3kW is a lot of capacity and would probably take a bit to recharge.

Re: Lifepo4 Batteries
Here is a good rated unit with a smaller 2100wh integrated battery. Which is about 1/3 less than the Bluetti however you can see it can run a coffee maker for 3hrs before needing a charge which is OK but nothing to write home about and as already mentioned you got to get the juice back in to use it again. This one cannot do 30a like the Bluetti though but gives you some run times in the add which will be helpful in your decision. https://ca.jackery.com/products/explore ... anic&gad=1

Re: Lifepo4 Batteries
The AC300 has a 30A AC input and output. It is a full UPS so will pass thru my shore power when plugged in. The shore power will also charge it.
I am looking at putting this between the shore power input and the panel so it will always be in use.

Re: Lifepo4 Batteries
I know this is an older thread, but one concern you voiced early on was not having the alternator redundancy provided by the isolators which you replaced with the DC-DC chargers.
Did you ever address this or did you just leave the alternators "separated"? If so, any issues or concerns come up so far?
Thanks for the great write-up and ongoing updates through your process!!

Re: Lifepo4 Batteries
The reason I ask is because this is the exact same setup/conclusion I came to when planning our lithium conversion. It's good to read about an almost identical install that is working properly!
We're just going with 200ah of lithium (for now ) as we have very low usage - but like to be on anchor as much as possible! If we ever decide to add an inverter I would definitely want a larger house bank, but for now 200ah will be great!
Thanks again!
