Backwoods Solar Submersible Pump
The Backwoods Solar 4AC-23-320 is a submersible pump ideal for many off-grid applications. The AC/DC motor can be driven with 130-190 Vmp solar direct or 90 – 240VAC from the grid, inverter or generator.
The Backwoods Solar 4AC-23-320 offers 23GPM at a lift of 320′.
This pump is Centrifugal. The pump liner, shaft and coupling, strainer, and cable sheath are made of stainless steel. The impeller is plastic. Base support and upper head is microcast AISI 304 stainless steel. Check valve incorporated in the head.
The innovative wet end design gives the pump superior sand handling capabilities and
provides maintenance free operation. Maximum permitted amount of sand: 120 g/m3.

Water temperature will affect pump performance. Pumps are recommended for use in
water temperatures up to 86 degrees Fahrenheit.
Centrifugal pumps feature dry-run protection so no additional protection is needed. When the pump runs dry for 10 seconds it will stop and then try again after 1 minute. If it does not sense water again it will stop and attempt to run again after another 30 minutes.
Solar direct applications should use a nominal panel size of 340 watts for standard applications, but larger 72 cell panels can be used for peak performance and a wider window of operation. Backwoods Solar pumps include an external pump controller free of charge. Follow the link for details on controller features.
