    Wrong default settings of Renogy DC/DC converter for LFP?

    I see. I'll be interested to know if/how your support ticket is resolved.

    Renogy 50a dc dc mppt charging profile w/engine on

    Not at the prices they charge here (I suspect). The 40A Redarc is about 2.5 times the price of the 50A Renogy (though I'm not sure its limited to the 25A+25A like the Renogy is, but still) ps. I love the quote in your signature

    Renogy 50a dc dc mppt charging profile w/engine on

    This is exactly the kind of information I'm looking for. We/I have one in a box waiting me me to figure out how - mostly where - to install it. The manual says it needs a ridiculous amount of clearance top and bottom which is excluding it from all the places I'd like to put it. If it doesn't get...

    Wrong default settings of Renogy DC/DC converter for LFP?

    FWIW you can also set the user parameters with the RMS-DCDC screen. They list it and BT-2 as optional, but really I think you absolutely need one of them. It's a shame that they don't have a third option of combining the two into one device - a screen that also lets you connect with your phone...

    Inverter Pre-charge circuit using off-1-2-both isolation switch

    Great. Thanks. Now I just need to work how to select the correct resistor.

    Inverter Pre-charge circuit using off-1-2-both isolation switch

    Hi everyone, Posting here to get thoughts on an idea I had for using a off-1-2-both isolation switch 2-way isolation switch (like this one on Amazon) for a pre charge circuit on a 12V 1500W inverter. It'd basically be operating the switch in reverse to normal, but it's just a mechanical switch...

    Bluetooth app

    No more (and probably far less) closely than Facebook, Google, Microsoft, Apple or any/your supermarket - this whole idea that China is spying on us completely ignores that literally every big corporation is too. Please don't @ me, I'm just making a point about how everyone is watching us.

    Renogy DC DC Charger w/ MPPT

    Could you just add a switch/breaker that disconnects the solar while you're driving?

    Feedback of 12V van system plan

    Ha ha. Thanks. I did it using Google Drawings. Mind you it took me ages, mainly due to procrastination and a lot of unnecessary fiddling with hidden shapes to allow me to move things around and allowing the curved connector lines wires to move on their own. Perhaps I should start a paid service...

    Feedback of 12V van system plan

    Indeed. I'd want something at least 250A continuous. However, it's also AU$80! ? The manufacturer actually sells a kit with the same inverter, same MPPT and solar "blanket" and a single 98Ahr battery. I'm not intending to have the inverter powered all the time - they also sell a remote switch...

    Feedback of 12V van system plan

    Thanks. I've made a copy to do later. Yes I know... and it really is true. It chews power; 180W I believe. We tried it once for about 30 minutes just to see (before I knew it was 15A). In the design I put in a relay so it can only use 12V when there is power coming from the tow vehicle's...

    Feedback of 12V van system plan

    Unfortunately we've already got the AGMs. I will happily replace the with a LiFePO4 when they're dead. I'm also bearing that in mind whilst designing everything. So the ANL fuse should be before the switch? (i.e. swap them) I've already got the bus bars so may as well use them. Yep. 147A...

    Feedback of 12V van system plan

    Are you suggesting the the extremely pricey Victron stuff they everyone online seems to fawn over may just be a little over-hyped?

    Feedback of 12V van system plan

    I didn't buy any of this stuff. I'm just the poor smuck who had to figure it all out. I've been reading all the things and watching all the videos since the van (and before any of this stuff) was purchased. I actually think the inverter is a POS and the AGMs a stupid purchase even if they were...
