  • Post in thread: How to charge my RV batteries from my Tow Vehicle Alternator while driving

    Yes, it supports lithium, just have to switch a toggle to lithium (and can disconnect the battery temperature sensor in that scenario too).
  • Post in thread: How to charge my RV batteries from my Tow Vehicle Alternator while driving

    There's an FLA battery setting as well. It has all the common ones plus lithium. You can download the manual from Renogy and learn all this and Renogy's customer support is also pretty responsive and helpful I've found. I removed the existing solenoid based isolator out of mine. This device...
  • Post in thread: DC-DC ON-BOARD BATTERY CHARGER WITH MPPT

    I just installed the renogy one if you have any questions you want to direct my way. So far it's awesome. I was looking for a DC-DC multi-stage charger but didn't like that all of them seemed to need you to run both positive, negative, AND a voltage sensor feed from the starter battery. This...
  • Post in thread: How to charge my RV batteries from my Tow Vehicle Alternator while driving

    Can confirm, I just installed this and it's such an elegant solution. In my opinion this totally obsoletes Renogy's own DC-DC dedicated chargers. Even if you already had a separate MPPT, this would be superior to use on its own than the 40a DC-DC because it has an internal voltage sensing...
  • Post in thread: Is it safe to mount panels on a vehicle roof using clamps?

    You've used them on a vehicle mounted setup? Just want to be clear since I noticed your signature has a bunch of different solar applications :).
  • Post in thread: Ideas for simple wind fairing?

    Just from the front to reduce wind noise and prevent upward wind force since they are held down with VHB.
  • Post in thread: Newcomer preparing my van for off-grid living

    Well for one I don't have solar. But when I do, I won't be adding enough panels to run the AC. I'll just be adding fans to keep cool.
  • Post in thread: Share your safety tether ideas

    Hi gang. I've finally got my panels mounted to my roof using VHB, but I'd like to go the extra mile by putting a couple redundant safety tethers in case something unexpected happens. Right now what I've done is used some steel wire (1/16" marine grade, the kind made for railings) and attached...
  • Post in thread: Newcomer preparing my van for off-grid living

    Hi all, I'm a software developer (working remote) and I have recently purchased a van and have been upgrading it for off-grid living. I plan to move into it in about 10 months when my lease runs out to try and save money and be a bit closer to nature (when I feel like it). Will's videos (and...
  • Post in thread: Share your safety tether ideas

    No. The wire is connected to plastic.
  • Post in thread: Has anyone TRULY figured out how to put a roof rack on a high top (fiberglass) van?

    I think i will be going forward with some kind of mounts that I can attach a roof rack onto. It seems like the Thule artificial rain gutter mounts will be best, mounted to the side of fiberglass roof. That makes sense that the main force will be a pulling up rather than pushing down.

    BTW sent you a DM about your address. I'm not sure if the DM notification dot shows up after subsequent messages..
  • Post in thread: DC-DC ON-BOARD BATTERY CHARGER WITH MPPT

    The renogy is limited to 25 Volts, 400 watts solar, so you have to wire in parallel. You can get greater than 25a from solar.
  • Post in thread: Share your safety tether ideas

    I'll try to get a photo of my current setup. The plastic I'm referring to are actually brand new thick plastic mounting holes that are part of the brand new MaxxFan frame.
  • Post in thread: Ideas for simple wind fairing?

    I may be able to slide them back just a bit, I'll have to check. Either way I can still mount something onto the panel itself, I just don't know what. Possibly bent door brackets. The hump isn't that high, it's more the dips on the side that I have to account for. I'll have to cut the...
  • Post in thread: Has anyone TRULY figured out how to put a roof rack on a high top (fiberglass) van?

    I ended up creating a roof rack using aluminum rails attached to feet that are VHB'd to the roof. This video shows most of it.
  • Post in thread: SOLD a brand new Renogy Rover 40a MPPT with Bluetooth

    Yes it is the 12 / 24 . Model number reads V030001
  • Post in thread: Ideas for simple wind fairing?

    I've got a video in the works that'll be on my youtube when it's done.
  • Post in thread: Has anyone TRULY figured out how to put a roof rack on a high top (fiberglass) van?

    I'm not sure the fiberglass roof is designed to hold anything of substantial weight so I've avoided looking at anything that involves mounting directly to it. It might be my only option though if I want more than two solar panels... :/
  • Post in thread: Ideas for simple wind fairing?

    Oh yeah I understand the dynamics of wind fairings for roof racks. No one is gluing anything lol.
  • Post in thread: proper fusing for 300w in parallel and question about renogy kit contents

    Hi all, I recently started installing a 300 watt renogy kit that I bought last year and am realizing that they may have designed the kit assuming you would wire the panels in series rather than in parallel. They provided a 10 amp mc4 inline fuse but I'm thinking that has no use so I'm trying...
  • Post in thread: proper fusing for 300w in parallel and question about renogy kit contents

    What is your reasoning behind the different sizings? What if I used a 30a breaker and 30a fuse?
  • Post in thread: Curious if this "back-channel" to the inverter could be dangerous

    So I did find out the logic of this particular transfer switch (GoPower TS-30 - which is just a rebranded Progressive Dynamics switch). From Progressive Dynamics manual: That being the case, I would prefer the reverse logic, so I'm going to swap the connections, that way the above mentioned...

    Yep paypal is good, DM me your paypal email address and we'll take it from there.
  • Post in thread: Curious if this "back-channel" to the inverter could be dangerous

    This is kind of complicated to explain so bare with me.. I recently installed an automatic transfer switch into my RV and connected my inverter to it so that now shore power and my inverter can power the same existing set of outlets. Something surprised me when I was testing it. I forgot that...

    SOLD!
  • Post in thread: Ideas for simple wind fairing?

    I'd like to make some kind of wind fairing to prevent as much wind as I can from going under the panels and pushing up. I don't want to have to drill anything, since that was the whole point of using VHB with this aluminum mounting rack setup. There are plenty of decent tutorials showing some...
  • Post in thread: SOLD a brand new Renogy Rover 40a MPPT with Bluetooth

    I bought the 300w Renogy solar kit from Amazon but ended up getting a different charge controller so I'm selling the one it came with. It was never used and still has the plastic film on the display. Also comes with the bluetooth module so you can see what's going on via your smartphone. I'm...
  • Post in thread: DC-DC ON-BOARD BATTERY CHARGER WITH MPPT

    I love the electric skateboard idea. I think i need to get one of those too! I imagine you'd be fine with a 100aH lithium like you suggested. I have two 125aH AGMs (that of course I can only get 50% of) but honestly I'm thinking I could get away with JUST charging off the alternator if...
  • Post in thread: Is it safe to mount panels on a vehicle roof using clamps?

    Thanks for the suggestions. What I may do is stick a standard unistrut L-bracket in place of the end clamps and drill into the side of the panels. I'd rather be done with it but I'm not sure how comfortable I feel with it the way it is.
