What do people think of those Cascadia 4x4 and Lensun Solar vehicle hood (bonnet for our friends across the "Pond") based, vehicle specific panels? I'm not expecting rave reviews. I know Will wasn't much of a fan of them (flexible panels that is--and not necessarily, worse, those situated on...

Ok, sure, longitude, weather, the angle of the panel (which if on some vehicle roof is horozontal)....length of day, there is no one setup... But that said, is there a basic rule of thumb regarding how big a solar panel in watts a person needs to, with an MPPT controller, trickle charge an AGM...

Two products from the Lensun Solar catalog motivate my questioning here. The first is one of their MPPT Charge controllers. This one: https://www.lensunsolar.com/Products/Solar-controller?product_id=534 It claims, with what appears to be no user configuration, to be able to charge batteries...

For all its limitations, the Renogy DCC30/50S will prioritize solar power to first charge a house battery and supplement that power with the vehicle's alternator if the engine is cranked. This got me thinking that maybe I could connect something to the alternator inputs on the device, that at...

Given that my vehcile is equipped with a smart alternator under the hood, that, as the name implies, won't delivery one constant higher voltage like was the case in the days of a non-smart constant alternator's voltage output, but regulate that voltage, presumably saving gasoline, based on the...

I'm sure that many of you are familiar with RV 120VAC transfer switches that, for example, will allow an RVs 120 VAC appliances to be run from a shore power hookup over, say, an inverter connected to a house battery in the absence of such shore power availability. Ok, sorry for the stupid...

Ok...your living in an RV with a nice size house battery bank that solar panels for the most part are able to charge, but there's those less than sunny days, that seem to always come in a stretch. So, lucky enough, to have access to shore power so mabe you charge your rig's batteries by...

Take a device like this: the Renogy Rego. It features the ability to hook up an optional Smart Alternator cable if the vehcile into which you are installing this product has just such an altenator. And on page 54 of the linked manual, the logic the device will use to have the house battery...

Is there such a thing is an other reliable 200W rigid vehicle solar panel that occupies dimensions closer to 60" X 21." Most I've seen are shorter and fatter. TIA

Hi: Allow me to express my goals--or at least what I think are my goals--in the hopes that those in the know (thank you in advance) can recommend products to accomplish this. Links are greatly appreciated. I own a Jeep Wrangler that has a roof rack that's rarely used. It's got three equally...

Hi All: As shown below in the attached picture, I have a solar panel attached at its 6 factory grommet points to a metal panel that is itself attached to my vehicle's roof rack. At highway speeds the solar panel will flap a bit and make some noise despite my attempt to make the zip ties which...

Can anyone explain/hypothesize why I can't seem to find US outfits that sell them? Sure, there's Azimuth Solar in Canada. These batteries seemed appealing to me given the wide temperature range over which they are reported to operate in. Thanks.

What batteries if any can be charged below freezing? I understand LiFePO4's can, but only at a fraction of what they could charge at, at, say 70 degrees Fahrenheit, without damaging the battery (BMS' notwithstanding that prevent this.) I've seen Dakota Lithiums, which seems to have strong...

I bought this 100W panel https://www.eco-worthy.com/collections/solar-panel/products/100w-12v-extremely-flexible-mono-solar-panel-1 in December of 2020. (This is just a link to the product on their seller's website. I get no credit if you buy it here or, like I did, on Amazon.) Today, at my...

I've got the above Renogy MPPT DC/DC charger, a 100W solar panel and a 20 amp LiFePO4 Relion house battery with the LT (low temperature) feature: where current is used to heat the battery, need be, first, before it is applied to charge the battery. Relion says this heating should slow down...

I'm a newbie. I own a Renogy DCC30S MPPT DC to DC charger. It's suppose to charge house and starter batteries from either a solar panel or an alternator. Initially testing has found my house battery to not be charged more than 13.08Volts, despite proving out all the connections to be live...

I've read my initial post on this a dozen times. Initial thread I must be stupid because I don't understand the answer. What I'm not is a troll--or at least I don't intend to be. I called the manufacterer...they have an answer that makes no sense to me. So I am reposting--not because I am...

Why do you suppose that either of these devices, which charges house and starter batteries from solar in that priority.... and when the vehicle is cranked, charges the starter and house batteries (i.e. flipped) in that order, only be concerned with the battery type of the house battery? Is it...

This battery came with two metal "straws" and what looks like a cleaning wand. Might someone explain to me what this is for? No manual that came with the battery or that I can find online explains these items. Thanks.

I must apologize. I am trying to solve a problem by asking the question differently when I post, simply as a product of my learning more each time. I have a 100W flexible solar panel on the roof rack of my Jeep Wrangler. With the energy it produces I was hoping for it to do two things with it...

I'm sure this has come up before. I'm new, including to this forum, and with my search skills limited I couldn't find the answer I strongly suspect is out there, much that I tried. As many of you I'm sure know, DC to DC solar charge controllers, likes one from Renogy, that charge both a house...

No--don't actually build me one. : - ) (The title is a reference to what Apollo 13 engineers had to make to get the CO2 of 3 astronauts, rather than 2, cleared out of a space, using only parts found on a lunar module already in space.) ~~~~~~~~~~~ Earlier today I asked a question that, to...

First, I want to apologize if my referring to products here is considered an "affiliate link." I simply own them and have questions on their use. I'm not endorsing nor suggesting avoidance of their use. : - ) Ok...here goes : - ) I have this 100W solar panel of the roof rack of my Jeep...
