    3 phase hybrid inverters, 48v battery compatible and grid tied.

    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...

    Solar pump inverter to power a vfd

    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...

    Solar pump inverter to power a vfd

    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...

    3 phase hybrid inverters, 48v battery compatible and grid tied.

    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.

    3 phase hybrid inverters, 48v battery compatible and grid tied.

    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?

    Do you think the Deye 12kw 3ph would run a 5.5kw 3ph motor, considering high start up current required.

    Doing both parallel and series connection on a single PV array

    Thats is such great news for me. Totally a great help and complete answer to my query. Thank you very much.

    Doing both parallel and series connection on a single PV array

    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...

    Doing both parallel and series connection on a single PV array

    Thats my fear. But I also know my fear may be unfounded. How do they test the short circuit current in panels?

    Doing both parallel and series connection on a single PV array

    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?

    Doing both parallel and series connection on a single PV array

    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...

    Doing both parallel and series connection on a single PV array

    Thanks for the battery protect idea. The pump has an mppt controller that receives 160v from panel but can also use 48v from battery.
