    Off-Grid Cabin - 120v AC and/or 12v DC buildout?

    I think you're misunderstanding me. I was simply saying that I agree with you that a hybrid system makes sense and that there's a lot of DC appliances out there which IMO makes sense to use if you can. I agree with you again WRT the lighting. Mine are on an AC circuit but in hindsight I wish I...

    Off-Grid Cabin - 120v AC and/or 12v DC buildout?

    Agree 100%. It would be awesome IMO to have a completely DC system. I strongly considered that when we started building but there were a couple things that held me back: 1) If you're wiring up a full house @ 12V then the voltage drop on the long runs become a concern which means you would often...

    Another Cabin build

    I second the others in that, without further information, it would seem that your inverter is unnecessarily large. Do you need split phase? (Do you have 240V applicances?) If you only need 6000W for minutes at time, take a look at what the surge capacity of different inverters actually are. For...

    Off-Grid Cabin - 120v AC and/or 12v DC buildout?

    My 2 cents would be to have a hybrid system and get the best of both worlds. There are a surprising number of the "big" appliances that run off of 24V directly like water pumps and fridges. My cottage is a 24V system and my biggest loads more or less are the fridge (which is 24V) and the water...

    Problem with Victron Battery Protect

    Yes I agree they make it difficult or subtle to know how to use their product "properly", and it's especially frustrating when the "proper" way involves buying more of their products, and the improper way, results in physical damage to the product and more disconcertingly, potentially everything...

    Problem with Victron Battery Protect

    You would think so. That's the configuration I had (I'm using a different inverter though) and mine went up in smoke. Admittedly when I first started using it, I had all of my DC loads connected through the BP including the DC side of my inverter and then I started reading about all of the...

    Problem with Victron Battery Protect

    So based on this it seems like the bottom line is: - The BP cannot be used with an inverter. - The BP cannot be used if there is a charging source. So... what good is this product at all then? It's marketed as a "protect" / safety feature in your system, but it can't properly do over current...

    Odd LFP/LTO configuration idea / question

    >> you can actually create the same size LTO bank for less than a BB if you play your cards right. yes, something I have quite recently discovered myself... >> My LFP batteries would be the 280AH EVE cells since they are so much cheaper than anything. Yeah. Full disclosure when I started...

    Odd LFP/LTO configuration idea / question

    Hi. I have an off-grid cabin which is currently running off of 1800W of solar and am using 4 of the BattleBorn 100ah and find that this is more than ample for my needs up there and gives me a couple days of autonomy with one or two critical loads. Normally I would winterize the place and...
