Hi there,
xxx is an Australian/Melbourne based company selling SOLAR water pumps to the Australian pumping industry.
We sell 36 V dc & 48 Vdc units that are operating above ground & under ground.
All of our units are SOLAR pannel energy supplied.
All are driven by Solar Panels & a intermediatery Control box which is placed between the SOLAR panels & the pumping unit.
Reciently, we have recieved enquiries for the inclusion of battery supplies to these pumping as well.
Proposed way forward:-
To supply battery supplies in place of SOLAR Panels we think that will need the following:-
Regulators, Maximisers, Battery protecters, Voltage & temperature sensor equipment.
All electronic of course.
Can you advise what eletronic equipment that is in your company product range, that can support battery supplied power to our pumps .. using multipule batters in series for the volt ranges of 36 V dc & 48 V dc . The amper amount drawn by the Orange Solar pumps is approx 20 Amp DC?
Please reply soon?
Best regards

Dear Sir/Madam,
For an OFF-GRID application of ONLY charging the lead acid batteries we are in requirement of suitable MPPT solar charger(altitude 4000 mts.)
Application details are as follows.
a] 12V/80ah x 2 nos batteries = 24V system and
b] 12V/80ah x 2 nos batteries + 12V/80ah x 2 nos batteries = 24V system each.(Total of 4 batteries )
These will be Exide/Amaron make lead acid batteries (distill water top-up /flooded ).
Regarding PV panel selection and details,
Kindly find the attachment for same. We are considering 380 W panel which will require charge time of 8-9 hrs.
We have available roof space on container size 2400 mm x 1200 mm (24 V system )and 2400 mm x 2000 mm (2 X 24V SYSTEM )
Charge Controller selection is as follows
From datasheet of solar panels we can see that the Imp is 9.56A.
We feel 20 amps for single panel system & 30 amps for duel panel system is suitable.
Total Quantity required is 70 nos.
Request you to please guide us for a suitable model / quotation for same
Thanking you.
Regards,
XXX
