I have tried researching on the Deye 3ph 12kw inverter. Some suppliers say its a low frequency inverter so this is really çonfusing for me.
I am also trying to figure out whether this inverter can meet my need to power a 5.5kw motor at 380v 3ph. I figured that this motor is rated 11amps and if...
I cant locate a spec sheet. However the solar pump inverter is veichi 7.5kw inverter. It receives DC power at 700v Voc from solar array and converts this to 380v ac 3ph to power the pump directly. Being a solar vfd, it varies pump frequency according to amount of insolation. Can this be used to...
I live offgrid on a farm. I have a 7.5kw solar pump inverter connected to 12kw array of panels. I recently acquired a silage baler that has a 5.5kw and 0.5kw motor within it. These motors work intermittently controlled by a vfd inverter within the control panel of baler. I would like to use the...
Thanks. This was really helpful. I had my doubts about 1 single unit meeting my needs. The supplier was very cagey on giving specific answer. I dont mind getting 2 units as long as my need to run the the motor is met, hussle free.
Thank you for response. It will be used in an offgrid situation. No mains power available.
So if I understand correctly, Deye 12kw 3ph hybrid inverter will supply 12kw per phase when running a motor?
It would. The MPPT has 120v as minimum starting voltage. 4s2p gives me a 160v configuration. During hot sun, I get 144v from the panels. I guess the difference is due to the panels heating up. So my secondary question would be how much less efficient would a 4s2p (160v, 20a) configuration be...
My main concern is will I damage the panels if I wire them both in series and in parallel? What would happen if by mistake both pump in the parallel conformation and the inverter in series were to be left on simultaneously?
According to the manual, I have dc 72 and a dc 110 pump. So it looks like I need a 72v or 110v battery. Seeing that this is not practical, it leaves me with only 2 options. Buy extra panels to power the inverter even though the pumps are only used 4hrs a day on average or figure out how to use...
I have thought about running the pump off the battery. I am afraid that on overcast days, the pump will discharge the batteries by evening. I am not available to monitor the pump during the day. Its supposed to fill a tank that then drains via sprinklers. On overcast days the pump will use up...
What would happen if I have 8 panels of 40v 10amp and I connect them in 4s2p configuration to power a dc water pump. On the other hand, I connect the same array in a series 8s configuration to charge batteries via mptt scc. I will have a switch between the two that I can flip to use the pump and...
I could try this. I forsee a situation where the 4 batteries being charged will trigger a bms shut off once voltage rises and there is a sizable gap between the 4 vs other 12 batteries.
I thought the whole purpose of the bms is not to overvault the group.
This takes several weeks using a power supply at 3.6v with all 16 batteries in parallel.
I have a 16s Daly BMS. I need to balance my cells but do not have a 48v battery charger. I can split the cells into 4s and use a 12v charger, but I do not have a 4s bms. Is there any way to use the 16s bms but on a 4s battery configuration so I can charge them in 4 rounds using the 12v charger...
Can you help me understand these settings below.
In particular,
1. What should be cell reference voltage.
2. What voltage should my state of charge ,soc, be based on, is it the cell reference voltage, or is it the voltage at balance.
I have a daly bms 16s 48v 250amp. The chgmos keeps going off despite the batteries not being full. How do I restart it and also how do I stop it from going off
Update...
I ditched the EPEVER 6420an and got a hybrid inverter 5kw Phocos anygrid. Hooked up the phocos to the lithium batteries and voila........ nothing happened. The lithium cells were not charging. I went into a panic for several minutes. Then I decided to do the one thing most people say...
Thanks alot @GXMnow for the many helpful suggestions. The latest suggestion from Epever engineers is that I connect a load to the charge controller and measure voltages again. I will do this this weekend but i doubt there will be any difference. Its starting to feel like a game of chasing tail.
Battery voltage remains at 13.3v via multimeter even when EPEVER screen shows charging at 0.1amps 14.4 volts. When PV is switched off, the Epever shows correct battery voltage of 13.3v. I checked for continuity on the Epever fuse described and this was OK. I did not remove the fuse and the...
When i had the lithium battery connected to the EPEVER unit, I left it for 3 days. The problem of not generating a charging current persisted.
When I connected the 12v lead acid, I saw the exact same pattern, the only difference was the voltage readings due to the different battery voltages. So...
It was directly from cc to 12v lead acid battery. No fuse in between. The battery voltage via multimeter was 13.3v. Battery voltage as detected by the EPEVER 6420AN cc was 13.3v (when PV connection is off). When PV connection is on, the battery voltage as per cc is reflected as 14.4v but...
This may be because you have a functioning charging device. I suspect that once I have a working charger, the "Chr MOS" should go on once it senses an inward current. I remember that when I first connected the BMS "Chr MOS" was on and " Dischrge MOS" was off. When I connected the inverter and...
My suspicion is that "chg MOS" goes "ON" automatically during charging mode.
My problem is that the EPEVER 6420 AN charge controller is brocken right out of the box. It will not charge.
Incidentally, I switched to a 12v lead acid battery just to see whether the bms on the LiFePO4 was causing...
I am using a daly smart bms.
If I get your drift about bms being in a charge stop mode, yet its only at 52v, would this imply the bms is causing the problem of mppt not charging. I note the green light ( in photo below) has been on discharge mos and I cannot change it to any of the other...
This is helpful.
I have panel + and - going into the mppt. Connections are correct and tight. The panel voltage at the cutoff switch was 111v while the mppt reads around the same voltage.
From mppt +ve is direct to the battery +ve. The battery terminal remained cold to touch all the time...
