total solar noob here,

i have just purchased a solar water pump that comes with controller

i am hoping i can run this directly from panels without batteries using 4 x 600w panels desirably

details of the pump controller

max input: 15A

Max Open circuit voltage: <200v

MPPT voltage range: 110v-150v

the pump

110VDC

1500W

max head: 17m

max flow: 55m3/h

when reading the manual it gives examples of 265w and 330w panels being used (8 for either, 2x4 series)

this example is based on panels with

max power: 330w

short circuit current: 9.33A

max power current: 7.15A

Open circuit voltage: 45.64v

max power voltage: 34.28v

when searching for such panels i do not find any with low max current,

all panels available are 9-10A

so i assume i should not follow their example,

as current would be higher than the controllers max input current of 15A

i was hoping to use 600w panels to save on space and seeing they recommend 8x 265-330w panels, i assumed 4x 600w would suffice

the 600w panels available are

Maximum Power Voltage(VMP)：36V

Open-Circuit Voltage(VOC)：42V

Maximum Power Current(IMP)：9.72A

Short-Circuit Current(ISC)：10.8A

would 4 of these 600w panels in series be sufficient for the pump ?

is 4 enough or is 5 better ?

or do i need to find different panels for better current?

as at max 4 x 36v =144v x 9.72A = 1399W

but 5 x 36v = 180v x 9.72A = 1749W

but output will be 110v, is the output current equal to the input current?

about the pump, it will likely be running for an hour or two at most each day in the morning once there is enough sun

will be sucking water from pond about 3m down from the pump, just looking for as much pressure as possible as this will be connected to high power sprinklers

thanks in advance to any replies this is all new to myself (sort of)
