Sharp Energy Sun Flux Installation and operating instructions

SUN FLUX USER MANUAL & INSTALLATION GUIDE
OFF GRID / HYBRID SOLAR HOT WATER CONTROLLER

WARNING
Be sure to read the Sun Flux user manual &installation guide thoroughly before beginning installation,
failure to do so may result in fire, electric shock or death. Installation must be carried out by a licensed
electrician following all relevant AS/NZS safety standards and local regulations of your state/territory or country
on installing this equipment.
Note: the Sun Flux is not an inverter and delivers a modified DC output.
1: Check and make sure the Sun Flux is not damaged in any way before beginning installation.
2: Connect 4 solar panels in series with a minimum output of 120volts/vmp 8amps
and a maximum output of 150volts/vmp 10amps or 185volts/voc.
Note: To size the solar array correctly you must divide the voltage/vmp of the solar array by the
resistance/ohm’s of the element to determine the maximum current you will receive, then you can
multiply the current by the voltage/vmp of the solar array to determine the maximum wattage you
will receive.
Using Standard AC elements 3.6KW 240v 16ohm’s element, 3.0KW 240v 19ohm’s element, 2.4KW 240v
24ohm’s element.
3: Turn off all PV solar power and AC grid power then test to confirm isolation before beginning installation.
4: Attach the Sun Flux securely in place using appropriate fixtures.
5: Connect the PV solar array to a 10amp DC circuit breaker, then from the DC circuit breaker to the Sun Flux
using MC4 connectors.
Note:The Sun Flux has reverse polarity protection for up to 10 seconds.
Be sure to connect the MC4 plugs from the PV solar array correctly or reverse polarity can occur
damaging the Sun Flux and the protections provided voiding all warranty.
6: Remove the protective cover from the terminal block on the base of the Sun Flux.
7: Connect the AC grid input wires to the AC grid input on the base of the Sun Flux in accordance with the
instructions below terminal block.
8.A: Single element tank.
Connect the load output of the Sun Flux directly to the standard single element electric hot water tank using the
standard AC grid input connection on the tank..
The selector switch on the base of the Sun Flux will give you the ability to switch back to AC grid power
if required.
No circuit breaker is required between the output of the Sun Flux and the hot water tank.

8.B: Twin element tank.
Connect the load output of the Sun Flux directly to the lower thermostat of the tank then connect the AC grid from
the home directly to the upper thermostat of the tank making sure of no connection between upper and lower
thermostats and elements.
Giving automatic AC grid power backup on the upper element when required.
Note: Be sure to set the lower thermostat 10 to 20 degrees higher than the upper thermostat for
maximum efficiency.
No circuit breaker is required between the output of the Sun Flux and the hot water tank.
9: Restore the protective cover over the terminal block on the base of the Sun Flux.
10: Turn on PV solar power and AC grid power and commence operation and inspection.
When the Sun Flux is powered up in solar mode the green led will be lit if the green led is not lit turn off
the PV solar power immediately and check the polarity of the MC4 plugs from the PV solar array are
correct.
When in grid mode the red led will be lit if the red led is not lit turn off the PV solar power and AC grid
power immediately and check all connections.

Sun Flux functions
1: Green led lit when in solar mode.
2: Red led lit when in grid mode.
3: Negative MC4 input from the solar array.
4: Positive MC4 input from the solar array.
5: Terminal block for AC grid input and load output.
6: selector switch to select solar mode or grid mode.
