hello from Ohio. I have an 06 sprinter van conversion that had a 200ah lifepo4 battery until I fried one cell by forgetting to reattach the bms. SO Last August I installed a redodo 12.8v 400ah battery pack. It is attached to an EPever 4215bn charge controller with the mt50 controller and 450...

Hello from Ohio I have a lifepo4 array in our rv. 16 3.2volt 50 amp hour cells=200ah ...450 watt total solar panels EPever charge controller with a cheap bms. I have been playing with the system for a good 2 or 3 years during the warm months. Never charged in cold weather. System was fine...

Oh the drag racing days... My 55 chevy shifting at the floor wit hvise grips and winning a trophy. Jim Head the Double A Fueler guy lived a few miles from us growing up. We were headed to the drags one night with his then C/Gas 55 chevy "Orange Crate" When they painted it the orange paint all...

Hello from Ohio, As a 50 year mechanic , weak on electric, that has always avoided complicated electric problems, I have ventured into the realm of a T1N Sprinter Van and solarizing it. That is , of course, having to completely rebuild the Gulf Stream's conversion. It was like that scene in...

I know this is an old thread but thought I would put my 2 cents worth in. On One of Will's videos he stated that VHB tape was the way to go but nearly impossible to remove. Gasoline ... I cut a swatch of an old tshirt, lay it over the piece of tape to be removed and keep it wet with gasoline...

Hello again from Ohio. A thought keeps rattling around in my skull. Not much else up there! I have a system in a freightliner van: 500w solar array ... Epever 40w charge controller ... 16 3.2v 50ah cells tied together=13.2v 200ah Lifepo4 battery. I am using the charge controller to charge the...

I don't like that 15 volt with what looks like a full/darkened battery and an unhappy face on your mt50 meter picture. something ain't right I would do a factory reset on the parameters. then reset them all individually to your battery specs. complete PITA to set! I have never seen 14.6V on my...

The panels are putting out 19.8 volts then a roughly 10 foot run to the circuit breaker which has 19+ volts before the tripped breaker. Engage the breaker which attaches to the cc and voltage drops to 14.2 +or-

My Bad....The system acted exactly as I described and every night the voltage would drop really low and turn off the charge controller BUT I was studying the battery yesterday AND I only had 2 of the 4 cells actually hooked up. Had to bring those low voltage cells up to equal voltage before...

Hello from Ohio, I have a sprinter van conversion with 450 watt pv panels and an epever 40 amp mppt charge controller. It has always seemed fine until now. pv array shows 19.4 to 19.8 volts at the circuit breaker when breaker is off. flip breaker on wired to the epever mppt 40 amp charge...

The thing is that it worked for a year before the panel shorted out.

Well I have triple branch connectors connecting all 3 into the single +&- going into the cabin. I have 10 guage i can try. Renogy told me the 8 guage wire will not work in my roof transition.

Hello from Ohio, I have a T1N sprinter van conversion. Installed 3- 150 watt flexible solar panels on the roof,(long story in itself) with about a 10 foot run down the rear to a 30 amp push button breaker and on to an EPever 40 amp MPPT charge controller and on to a 4s-BMS attached to 16 cell-...

I am sorry yes they are lithium Iron

Thanks for reply I am thinking the low side parameters are way too low also. Am gonna study that If I have it figured correctly there are now 3 separate mechanisms to charge the house batteries. The house and vehicle systems are separate BUT there is an automatic solenoid switch that kicks in...

Well I got it working Had to have been The Lord I am not bright enough When I originally hooked up the BMS it said to run the cc batt negative through the BMS to the battery. I touched the battery ground to the charge control batt negative. It sparked and the controller started working...

A problem just came up. The charge controller just died. Cloudy couple days here and this morning went out and shunt showed battery level at 11.6v and the charge controller powered off or dead. The remote meter is blank and the power lights on the coltroler are dark. 300 watts combined...

Hello, It all seems to work fine now. I just use the charge controller to charge the battery now. Channeled through the bms. The load then is powered directly off of the battery. I do not utilize the load side of the charge controller. Seems to work fine. I have 300 watts of pv on a hinged...

18.6 volts from panels to controller is there a fuse inside the controller??

Circuit breakers everything is tight Panels putting our 18.6 volts

Hello, I am a full service mechanic for many years but never paid much attention to electric until this build so I m a novice here Please be gentle as I already have a sore butt. The charge controller went dead overnight. scenario: 2006 sprinter van factory conversion 16cell 3.3 v =12v 250ah...

Rick, Thanks so much! I have learned a lot through your tutelage. The parameters are now set. Had to bounce around to get it to take them all. had to incrementally set the under voltage warning reconnect voltage down to 11.6v It will not accept 11.5. I thought that the bms ground was too small...

Thanks I will try to set the parameters Problem is though that the scc will not "turn on" the power to the load. will work on parameters

Thanks for listening, each cell: Nominal Voltage 3.2V Chemistry LiFePO4 Nominal Capacity 50 Ah Cell Type Prismatic there are 4 cells tied together creating a 12v batter then there are 4 of these. Son in law had me use a 4s bms w/1 lead for each bank. All of the cells for the last year have...

The scc remains attached to the battery since the initial hookup. I have though disconnected/reconnected the solar panels intermittently, unswitched/ unfused while preparing to mount them permanently.

Question: Could the system, as I have it now wired, have caused the failure of the scc. Improper or not, the Inverter switched on activates the entire 120 volt system. Incorporated in the van's system is an ac to dc converter causing 12.6 volts to energize the 12 volt system including charging...

My problem is not with the battery protector. The scc is the problem and it is wired independent of the bp and one is turned off when the other is on although the charge controller is inputting voltage when the inverter is in use.

OK the 3000w inverter is wired directly to the battery through the Victron BP 12/24 100 using #2 welding cable for pos and neg with 300 amp fuse. The controller load pos is a #2 welding cable pulling at most 20 amps at any given time...9 -5w LED house lights and the 12v fridge. controller...

Hello from Ohio, 2006 sprinter conversion van. Building system using 16cell 3.3volt = 200 ah 12 volt battery bank last year Purchased and installed Tracer 4250 BN charge controller a year ago. Mounted but never integrated into van. Also have the mt-50 meter. Just purchased 3 150 watt panels and...

Thanks for allowing me to ask questions. Ok I have a Sprinter van conversion. The lead acid battery went dead in half an evening so I decided to go with Solar...Have not bought the panels yet have most everything else. See pic if they allow pics. My question is on the initial wiring. I am not...

New guy here from Ohio, Will, Thanks so much for your expertise and ability to relay all of this to common folk! Whatever knowledge I have or do not have likely came from your Video's. I am a long time equipment maintenance mechanic/Welder/Sheet matal man with a limited/ slim-to-none...
