replaced the 2 x mosfets and it`s working again.... no other damage lucky... but why did they go pop? crappy solder joint causing heat? when i re-assembled and put god quality clean heatsink thermal paste/ compound between mosfet and heat sink block, hopefully to soak more heat away from the...

ok found some details.... just need to know the fan operating voltage? Cooling fan start condition: Output current>8A or System temperature>45℃ Cooling fan shut down condition: Output current <7.9A and System temperature <45℃ ok found, when the fan comes on it run at 5v i suppose i could have...

I have a small (ish) follow up question(s) i have a 2 x 12v 100AH lithium batts (with 50 amp BMS, over voltage, under voltage, short cct, and temp protection) currently not setup on the off grid but will be set as 24v (2 batts in series) Q1: i have a 5 amp CV/CC power supply, can i use this to...

This problem has got the better of me and I’m putting my hand up for help.... Watchpower is (surprise surprise) actually working ok for me, program runs, can see live stats, can change parameters on the fly, can view log files, charts etc but! this is odd.... As the program will only log data...

the main feeder cables from the batts to the shunt / DC breaker and then back to the inverter are 16mm sq the link cabel betwwen the two batts is a 70mm SQ all crimped with a professianal crimp tool are you thinking voltage drop? i can go and measure across the cables to see if there is...

--udate 4:15pm-- pannels been in full sun all day have the bulk charge set to 28.6 and the float at 27.6 couple of things i did and noted... 1: if i disconnect and reapply the PV source (off for 30 seconds then re-connect) the inverter switches over and runs purely on bateries (expected) 2...

does anyone have some photos of what a good/bad tube looks like?

I won't believe this until I see it. Your manual reads exactly like a Growatt that's made by Voltronics.

it`s ok does not matter anymore the batteries have been sold on and i have new lithiums

Marty, i just read your PM. i did not realy get any further other than what vision send me this is the email from vision Oct 2022 Darren Chen sent from iPhone On Jan 28, 2023, at 06:53, Richard Gormley May 2018 Darren Chen sent from iPhone

I am looking at buying some AGM batteries and was trying figure out how old they are from the stamped numbers and letters on top can anyone tell me the production dates from this? model: Vision HF12-560W-X stamped on top BJ26HA7GK34 Cheers, Richard

At what voltage will the BMS do balancing on any out of balance cells(if any) in the battery? will 3.5v /cell (14v) let the BMS balance the cells? i did an experiment, i charged a 12v 100ah (voltx basic) at 5amps CC to 14v CV (using a power supply) the battery i presume was at mostly at 100 SOC...

ah ok thanks for all the answers yes i mucked up my charge /float voltage (as you mentioned, i will set to Charge 28.8v and float at 27v)

i`m also assuming that the power supply that has a rated output of 20 AMPS will only push 20 amps into the batt, and once the voltages rises the current will taper off to around less than 2Amps ..... noting that i cant "set" the current, only the voltage (now at 14.4v)

i build a DIY evacuated tube solar hot water heater system back in 2010 piped fully lagged, non return check valves, basiclly all the stuff myself...works great! 15 X evacuated tubes 200L ground reticulating tank connected to a instantaneous gas heater all still working great! (recently the...

does anyone know the voltage of the fan on the back of the RD6024 (on the back of the pcb) and is it load/ speed based ? or just when it gets to 8 amps? if just turns on 100% i wish to tap of the fan supply lines and run a small external fan attached to my case to extract any heat. (i use a...

I got an answer from whirlpool.. so the mystery is solved The inverter does a insulation resistance test every 24 hours. The startup will be due to the inverter being disabled/enabled during the test, iirc it takes less than a minute to perform.

i installed a 15 tube evacuated solar hot water tube heater been working great 13 years now my question is where the copper tips go into the manifold with the thermal transfer grease, how often does this thermal grease need to be cleaned off and replaced?. i have not pulled a tube out and...

anyone? UPDATE: for what iy`s worth i sent an email to Vision USA, and they came back saying "Oct 2022" i presume the B:2020 and the J is oct follows the standard i guess, i have asked them to follow up on the remainder of the letters "26HA7GK34"

my mdel is not a growatt it`s a powmr HMS-3K-24V inverter spec mentions no load and power saving consumption i presume this is the power consumed when it`s turned on but doing nothing anything... if so how do i know how much power it using when actually inverting and and doing it`s job...

powmr HMS-3K-24V solar input just stopped charging ? all was working as expected, then the solar input charge just stopped. and has not charged from solar since. the HPS24V3000VA spec sheet says may open voltage 102v open circuit voltage and 40A max PV input dc for the MPPT input. i measured...

i have 10 panels to mount wire to my inverter/charger each panel is 24v at 7amps they are 10 years old and still outputting around the 7 amp mark. going to have 2 in series (48v) and then the 5 sets in parallel. (sharp NU-185A1H) inverter is a powermr HMS-3k mppt scenario 1: Do the looping...

what "back to charge" voltage should i use? i presume this is a setting that i can set to take the batts down to 10% SOC at 24v (2000 cycles?) or only down to 25.6v (20% SOC) 3000 cycles?) i realy dont know what the SOC is on my batts other than letting the charger do it`s work based on what...

oh "Those BMS' are not SmartBMS" so what functions do they provide? high/low voltage disconnects and over current? Do you the link to this information, i would like to read it in full. Cheers, Richard just spotted this on the voltx site "The BMU is also equipped with equalisation modules"...

had to go to sleep last night ... anyway this morning measured the volt drop across the entire system batt volts 27.1 pushing 18 amps into the batts see the attached photo it shows all the voltage drops in mV across each section. measured on the bolt or connection ternimal screw inverter/charger...

After having the batts on the 5A PS (at this stage the volts was only set to 13.6 over night) the current dropped to 4.16 amps (with two batts paralleled. I then hooked the 20 AMP power supply and set the volts to 14.4v across one battery, the battery drew initially drew 16 amps then dropped...

ok thanks for the info,,, for the moment i will go more simplistic "look and see and feel" evaluation we had a 25deg partly cloudy day yesterday pump on high, the tank went to 43deg c today is a similar day temperature and i have the pump on low....stay tuned for the end of day tank temp (i...

I have 2 of the "aldi" voltx 100aH lithium batts the manual states for the voltx basic "for optimum performance , you must charge to 14.6v" "over protection is 14.4v" so how can i charge to 14.6v if the over voltage protection on the BMS is set to 14.4 volts? also i presume i should only...

.

thanks Mike for the info... i have a 5 amp balancer on order to help with the series linking out of balance problem,, (HC01) from fleebay as a further observation, as i was watching the batts charge in real time when it hit excatly 14.4 the charge stopped (it was charging at 2 amps) i left...

just installed a 100a powermr charge controller, all working good... but... Noted that when the fans kick in the air is sucked from the two TOP fans and pushed down and out of the lower side vents I thought that normal convention would be to suck "cool" air in from the lowest point of...

inverter: Fronius Gen24 PLUS 8KW panels: 8.8kw bifacials batts: BYD 11.3 HVM Every night when running on batteries when i look back at the graphs and stats i always see a green dot on the battery discharge curve that says "battery mode: startup" any idea what this is? seems to be around 1-2am...

My trusty old Epever tracer 4210rn unit decided not to start up after a shutdown (changed some cables / shunts etc) no LED display when the batteries are connected. we pulled it apart to see if there was something obvious.. the main MPPT caps were way out of tolerance... (they were potted...

After the full charge and balance last night with the two batts in parrallel i hooked the two batts in series and connected them into the system hhmmm i have a problem i think... ?? the batts are charging and disharging (cycling) every 10 -15 minutes pulling 20 amps from the batts then sags...

Here is the response from Voltx when i queried the voltage settings hhmm i thought that 15V is way to high for a lithium battery on the upper level of protection. this is the Email response Hello Richard, So sorry for the delayed response. As per our tech team the Overcharge protection should...
