Well do we have any knowledgeable folks on here who know the ins and outs of solar panel charging/maintaining a 4WD all electric UTV 48 volt / 2080AH capacity ( 4 each Discover Dry Cell technology batteries) I am looking for something quieter than my Yamaha 450 Rhino obviously

Here is the deal ..my farm in the boonies has no electricity available (where I hunt of course has lots of hills n log trails) .. and age, knees and back need to ditch packing into the stands in the dark and ice and snow and mud

I have looked at electric trail bikes but shoulders as well as railroad rail like places covered/camouflaged with hardwood leaves ankle+ deep (in case you have never ridden a motorcycle if you try crossing a rail at no angle to speak of you have a 50/50 chance of busting your keester) have me luke warm on an electric bike ..

I have looked at quad/atv's but the only thing even slightly interesting is a Daymac Beast 4X4 ($5999.99 +$600 shipping and no supporting dealers stateside) they have no US presence (Canada only)

Then there WAS the Polaris EV UTV which basically (never seen one ..just read about) used a battery n motor system about like a golf cart including a lead acid deep cycle battery that even in the best energy management conditions of constant battery watering charging etc will degrade very badly and battery reliability starts becoming an issue in three years and that long only if it doesn't sit unattended all winter or summer

Polaris does seem committed to electric for they have come out with a replacement for the EV model but it's price is that of a new automobile !

Enter the Hisun Motors Sector E1.. 4X4 ..Yes it is Chinese built and yes the jury is still out as to how strong it is now as well as to it's future with regards to reliability,performance, parts etc etc HOWEVER ..

The dealer 40 Min from me says Hisun Motors has a 300,000 square foot headquarters in McKinney Texas ..so at least this company seems intent to have a presence

Plus things I believe are really going to heat up as far as EV electric off road models AND technology offered by the major US atv/utv marketers ..but I stll have the need to solar charge/maintain one whether it be now or in two years

Heads up for anyone thinking EV hunting rigs ..study study study ..especially energy source (batteries) location of motor and type of motor and make you own decisions ..for example Lithium batteries are the cats meow ..most of the time ..and with present technology ..did you know a Lithium battery will not take a charge if the temperature is below 32 degrees ?? ( so I read ) ..there is a work around assuming the battery has some life to turn on head lights or whatever to create internal battery heat enough to start taking a charge ..NOT good if you rig is in an unheated area ..further a Lithium battery in cold weather (I read) gives up a smaller amount of it's total energy than other traditional storage batteries

Gents and ladies every thing I am discussing is from reading ,reviews, forums, feedbacks Etc ..I am inviting you all to input from you knowledge or hands on experience as I'll bet I'm not the only bunged up old fart looking for a way to stay in the field ..safely.

I'd like one, but get a hold of me when batteries go
1000 miles on a charge in -30 degree weather in the dead of winter, and be able to recharge the battery in 15 minutes
after checking on the cattle or driving across the State.

Plus I don't think our economy is doing to bad if people
can pluck down $70,000+ for an Electric Vehicle.

Kind've similar, if you can replace solar panels for generator...

As an industrial pipefitter, many a night was spent during the extended deep-freezes of winter for over 3-decades, keeping things thawed out. As soon as we'd thaw a pipe and keep the water (or other processes) trickling, somebody behind us would shut the valves and things would quickly freeze again. We had electric vehicles of burden to run the crews around the mill. Electric vehicles just can't withstand this. So, as a feeble effort to extend the range on these vehicles, we had a running generator on the cargo deck, plugged into the charging circuit. It was no help to us at all.

So, my take is, to keep batteries topped off that are otherwise not in use, a solar charger could work. But if you're expecting immediate results of any kind, you'll be disappointed.

This is also not much different than my camping scenario. I use an inverter from 12v batteries to keep my cpap running all night. It works well. But then, it takes 8 hours of charging via a gas powered generator to recharge the battery for the next nights use. If it takes a Honda generator 8 hours, a solar generator will take more hours than there is available sun to accomplish the same charge.

Yes I'm not expecting quick charges at all ..If I hunt all day.. I myself will need a few days to recharge ..so if I can get a system that keeps the batteries "UP" and can recover batteries to full charge in 3 or 4 days I would be good with it ..
Unfortunately I do not think the technology ..or better yet the know how within the industry that would build this kind of machine (who are gas orientated and electrically challenged ) to know how to build the proper electrical connections ( to make connections corrosion proof and vibration/loosen proof) among the battery packs, controllers and chargers to keep the system reliable as all are series wired and where ever the break is be it one battery cell, switch or connection is a Rosie O'Donnell

As I've said ..2 years down the road will make some real changes in this market segment

Thanks

I'd suggest your charging system be based on one of the solar panels charging a battery bank that in turn stores power. That way, you can fully charge your EV overnight from the battery storage. I think GENERAC calls the system a 'solar cell'.

Interesting.. one thing that blows me away .. and if true I cannot understand how Lithium batteries are the go to choice for EV vehicles and that is a Lithium battery will not take a charge at a temperature at or below 32 degrees???
So even if I had grid power.. if my EV is sitting in an unheated shed any where north of Memphis Tn from November to March how will that work??
Maybe only certain "kinds" of Lithium works??

The battery pack has its own heating and cooling system, if the EV is always outside in the cold it will use power to keep itself warm enough to use. People that live in cold weather climates that have no indoor storage learn what the "scheduled departure" setting is pretty quickly.

I'm sure this simplistic analysis is wrong somewhere - but I don't think it is possible to use a portable solar panel to charge a vehicle like that unless you have a fixed solar installation at low latitudes and sized to the task.

A 100W solar panel ($140 and 10 lbs and close to 2ftx5ft unfolded) would take something like 43+ days to charge the battery of the Hisun Motors Sector E1. Assuming 48 V battery at 2080 ah, neglecting a bunch of real-world inefficiencies, cloudcover, heating losses, etc.

I had set up a friend's Dock with a solar panel system. It had a 3'x4' array, a battery box with a deep cycle battery and a small inverter. It could run the boat lift, led lights and the battery tender on the boat. Way cheaper than running and maintaining power the extra 100yds from the house. I've considered building a car port with a solar panel roof if I ever do any sort of EV. Since I just got a new roof on my barn I might panel the South Side for about 10kw.
