i am in VA,do you still have them?

so no problem putting these into series or parallel?

ok-here are the pics of solar panel specs.

will do,i will get it tomorrow when i get back to farm.

yea,been doing this for a while,i have a couple dozen solar panels,an off grid cabin i put together before all the 2020 craziness.been on this board since 2019. these are for a different project. thanks tho. the reason i ask about these particular panels is because when i opened the junction box...

just asking,these are used.tested ok,got them free. thanks for the reply.

can i use the panels as an off grid system? is there a difference in on-grid vs off-grid panels?

my daly 12v reads everything in reverse.charging it show minus,discharging shows plus. weird.

i have 2,second one still in unopened box. both perfect condition. been in storage for a year now. maybe i purchase the relays. where to buy?

i just needed a clean BMS ,no extra stuff like relays that i need to purchase.too much stuff bouncing around in my van camper. one and done.

no

my dc50 died the other day.no reason,just died.only 8 months old.

my renogy DC to DC 50 amp MPPT/Charger died today.the MPPT part quit working.no reason,just died. happened today.only 8 months old. i replaced it with a Kisae 50 amp DC To DC mppt/charger. what a disappointment on the renogy.

that only applies to the 4s ones. i also have the 8s,it will swap.

depe it depends on the production date. that firmware you linked will not work on the new batches.ask me how i know. i am searching for new firmware,that firmware messed up my 4s 250A DALY pretty good.

where can i find the firmware for the 4s 250A models? need the monitor version. please,i need help. Thanks.

i have 400 watts of solar on the roof of my van.hooked into the renogy 50 amp model. 400 AH of lifepo4,and i replaced my alternator with a 235 AMP output. works great.it does trickle charge the starter battery.

where to get new firmware? any one know?

renogy monitoring screen works on my DCC50. if anybody was wondering.

where to purchase?

maybe it went to sleep. put in 15300 in sleep time so it wont do that.

i bought 2 DALY BMS. one is a 4s 250A-the other a 8s 300A. both from currentconnected,the owner is a member here. they work very well. i wonder why people are having issues? different PCB or something?

that was my thought as well.

i use them in my battery box to snug the pack.

ok,after some research i need to flash the bios for it to work. need to find the proper files.

i plugged the screen into where the bluetooth dongle was,is this correct? it is a DALY 4S 250A model. it is plugged in but no data comes thru.screen powers up.

i have 12V 250A DALY.i put on the charger,them touched p and b,fired right up.been working great.

i just got and installed the 12 volt,250A DALY BMS a week ago.works great.solid runner.will get more.

what is a light board?

what would 0 do?
