any opinions about cheaper imported mppt units ,prices asked vary greatly , but in relation to specs they appear to be the same as the branded products, as per warrenty you could get a couple of duds and still be ahead? i am looking at changing my pwm ontrollers to more effecient mppt but is it worth paying the $$ just to get a brand name , IMHO warrenties are only honoured if you can find the reciept

I search youtube for reviews of a particular mppt controller. The cheaper ones seem to work ok but may have a few less features like a phone app or a digital display

Well I went with a Epever X-Tra N 4210, it has worked extremely well over the last couple of years, first with a couple of GELs then rewritten for the Lithium, the newer models have lithum in their programming, it has a full display and can be set up without the need for some phone app, it can also have a monitor plugged in so the read outs can be viewed remotely in van, adjustments to settings can be done on the unit or via the monitor which is very handy , its a good self contained unit no need for other bits to be added ............. once set up its set and forget really.
I am pretty sure the Kings Plus 40amp MPPT Controller is the same unit and the run down they give covers it all..............

As you have seen in my previous post I am a classic techno tragic. I just want to go out and enjoy the journey and exploring new (and old ) places, if the lights come on that's good , if I can't light the fridge or the stove that's bad , too much of our life is spent looking and fiddling with things I know nothing about and at my age will never even try and understand , ah well maybe time to stay home or just go to caravan parks ,BTW. On our latest adventure we saw a number of parks that look like ' heavens waiting room ' a lot of boomers who sold the family home to buy the dream rig , 20 years down the track too old,too frail,too broke to move just sitting waiting for ???

Well mate you would like Big Mals set up, while I may like to know the Why's and How's things work I don't want stuff around with them, KiSS is always of primary importance with my purchase's, Big Mal runs its own show mostly so I can throw a line or just sit back thinking about how I could ................. If I have to start using parks then its time I hung up the keys I think, they are not only expensive but require a lot of work getting in position on some stamp sized spot, too much work then I have neighbours, yuck and I would be travelliing to some itinerary, not me ........................ Most off grid camps I'm set up 15 mins after driving in, beer in hand and Sat dish sorted.

This Boomers have it easy is just BS, I worked my guts out for near 35 years so we could own our place and eventually paid my house off at retirement so not selling up any time soon and I'm certainly not selling up for some Big Rig only to find I'm left stranded with nothing when old timers throws a curly one, I'm 70 now so know full well the joy of getting out of bed of a morning to be greeted by creaks and groans, lol,lol but I'm vertical so gotta be a good day...............

You would like the Epever, just plug in the wires push a couple of buttons for initial set up, like all of them then forget about it .............. if you want to see whats happening no need to stuff around getting bluetooth to work on the phone or some such rubbish just use Mk 1 eyeball...

Yes they are the same. I compared the 2 manuals. I found a few rebranded versions of the same model too.


The kings one is listed at $169 but if you buy it with a 6M anderson cable it's only $114...
Thought so ............................. Just like my lithium battery it was about $200 less if I bought a led torch as well, of course I did, both good value......................
