Mode 2
The SOLiC 200 senses when the house is feeding
back into the grid, and then varies the power level
available for immersion heater use, until the grid
feed-in power is reduced to zero.
For example; if the house uses 500W and the solar
generator is producing 700W, the SOLiC 200 will
sense that power is being exported. The SOLiC 200
will then increase power available for the immersion
heater to use until no power is being returned to the
grid. The SOLiC 200 checks itself 20 times a second,
striving to keep this export amount at zero.
Benefits: Good efficiency can be achieved for most
homes, giving maximum flexibility with the ability to
“fit and forget”.
Regardless of which mode is used, the SOLiC 200 will
divert excess electricity to the immersion heater until
the water is hot. The temperature of the water is set
by the immersion heater thermostat. Once the water
is hot, the immersion heater thermostat will click off.
Power will continue to be available to the immersion
heater (indicated by the green “immersion power”
light), so long as the solar generator system
continues to export power. When the immersion
heater is powered up by the SOLiC 200, a gradual
changeover ensures that a consistent level of power
is maintained for the rest of the house to avoid lights
flickering.
