15 volt at the battery could be the MPPT controller being in BOOST mode initially .... looking at the specs of the controller max output volts of the controller would appear to be 14.7v - allowing for the volt gauge to have a bit of inaccuracy it would appear to be in boost mode.
My 1 week old ( same unit, but not a "kings" rebrand) was charging 2 fully charged FLA batteries at 16.5 volts, this morning. Prob would have fried both batts if I didnt shut it down when I did. Both batts were reading 14.98v AFTER I disconnected this 20 A mppt . Its going back to Amazon, where I got it.
Looks great man. Should suit you great out in the field to charge camera batteries, phones, drones, and all your other equipment. I built my own too my scratch. Tool a while but works great.
yes,those mppt controllers .ive had 2.the first one didnt charge,the replacement one did the same as yours,my battery went over 16 volts.got a refund from kings and bought a kick ass 40 amp one for $90 on special.no problems since.
@@LiquidAntler Bugger. I hope that's not a common issue with these MPPT controllers. I have one that I'm yet to install. I ordered the 12V control box today, and also saw these: 'Kings Plus Premium 20A MPPT Solar Regulator | Push-Button Lithium & AGM Compatible | Digital Display with Volts, Amps and Watts | Inc. Two Quick-Connect Plugs' So I bought one of them. I have three panels to connect, and two batteries (so far). I've also got a 3000W inverter, and a 3000W petrol genset just in case I need it. I have a dual battery kit but also want a DC-DC charger so I can use one panel to maintain charge in the vehicle batteries in case of an alternator failure. I know just enough about solar setups in vehicles to be a danger to myself, so this should be fun. My one saving grace is that I can connect wiring correctly, and safely.
I have a Kings control box, But after looking at the ones for same price at BCF, BCF ones are much thicker wire on everything, from internal to Andersons. Only difference id make
I have the same problem with the kings solar regulator. I was suspicous why my battery was getting so hot. I hooked it up to a battery monitor to monitor voltage on a graph and was able to see it always charge battery at 14.7 to 15V, even when battery is full it doesn't drop the voltage to float which it should do at 13.5V
@@LiquidAntler Yes. Recd mine 6 days ago and charging voltage is all over the map at 15...15.5.....and 16.5v this morning. Sending it back to Amazon, whete it came from
@8:05 you're getting 15V probable because you're connected directly to the battery, instead of connecting to the MPPT's regulated load output, i'm just guessing
Good to c another vid mate👌 Andrew R could b correct re it being in boost mode so did it drop down to high 14 volts after a while? If it didn’t double check with a quality multimeter the voltage coming out of the solar controller and at the battery as the voltmeters r known for being a bit inaccurate? If u r getting 15 volts at the battery u need to disconnect it ASAP as it will kill your battery eventually? If u need any further help hit me up on fb or Insta as I work in the solar field in the off road camper industry so might b able to help u? Cheers Darryl
I was so unhappy with the wiring the box and how the switches are wired up!! I will never buy another kings electrical product!! Ive started using kickass Solar stuff now and loving it so far
Hey mate how did you go with the regulator ? Did you end up keep the kings one or did you switch it to another brand ? I’m having the same issue with my solar regulator
Hi Mate I had the problem with my regulator I have a 250w solar panel and a 20A regulator same problem found out the regulator was to small for the panel so I put a 30A regulator in ant it works great

Bugger, yea seem to be very dodgy units!

Thanks, mate. Unfortunately, the mppt regulator is crap. Sent it back. New brand on the way
@@LiquidAntler sweet, have a look at the Victron. It doesn't have all the digital readouts but is a very well-known solid performer in the industry.

Yea ive ended up returning it 😪 will do an update video when the new renogy one arrives

Ok will check them out next time i am in a BCF 👌
Yeah the BCF 1 is alot better...seem alot more robust .. I keep away from kings
Get rid of the kings mppt Aussie arvos made a video on this charger and the volt meter was reading 15.1 after a few months it ruined his battery
Yea I did a follow up video explaining a similar issue I was having. I got rid of it for a Renogy unit 👍
looks nice and neat
Thanks 👌👊

Victron solar regulator should be the best and last one you'll ever buy. It's future proof
Ended up upgrading and went for a Renology regulator. What a difference 👊

Hi Darryl, Yes, it does seem to drop down below 15 at times. I will keep and eye on it and keep checking with a multimeter 👊
@@LiquidAntler too easy mate let me know if I can help👍
I was so unhappy with the wiring the box and how the switches are wired up!!
I will never buy another kings electrical product!! Ive started using kickass Solar stuff now and loving it so far
Nice i will check out the kickass gear 👌
It was helpful but I wanted to see how you wired up the regulator to the control box
Hey Tony,
Just reading comments and think you may get some ideas in my video .
Cheers
Out There Touring
I found the same power box on Amazon US
Yea generic box just branded with Kings
would you send the link on AMAZON? I COUND'T FIND IT
Hey mate how did you go with the regulator ? Did you end up keep the kings one or did you switch it to another brand ? I’m having the same issue with my solar regulator
Hi mate, i took back the regulator. It was a constant problem. Changed tp a renogy regulator and loving it 👊
Hi Mate I had the problem with my regulator I have a 250w solar panel and a 20A regulator same problem found out the regulator was to small for the panel so I put a 30A regulator in ant it works great
You are getting 15V because your MPPT controller is cactus. Grab a Victron 75/15 or 75/10 MPPT controller before the el cheapo kills your battery.
Agreed, ended up sending back and buying a Renogy unit
