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.
