Secondary Load Status LOAD 2
Secondary Load Time
Example Scenario for dual system:
The secondary load will be activated 3 minutes after the thermostat in the immersion cuts off &
there is surplus power.
1. The primary load thermostat cuts off & there is surplus available.
If the 'Load time' is set to 60, the unit will deactivate LOAD 2 after 1 hour and activate LOAD 1. If
the LOAD 2 thermostat is still at 'cut off' stage, the LOAD 2 will be activated after 20 minutes and
the whole cycle will continue.
Sensor Clip Installation
The correct installation and positioning of the current sensor clip is very important for the efficient
operation of SOLARIMMERSION IV. Wrongly installing the sensor clip could result in importing of
power and the user incurring additional costs for electricity.
The sensor clip should be installed at the main incoming grid supply to the building which could be
from the utility/electricity meter. (Please note ‐ it is Utility/Electricity meter NOT the PV generation
meter). Close the clip around the Live or Neutral cable from the utility/electricity meter. Please
ensure the sensor clip is positioned nearest to the utility/electricity meter as possible. (Only open
a consumer unit if you are qualified to do so or are an experienced electrician).
If there is more than one consumer unit, the clip must be positioned at the primary income source
– before it splits.
IMPORTANT
SENSOR CLIP HAS TO BE ON THE UTLITY/ELECTRICITY METER TAILS AND ALWAYS ENSURE THE
CLIP IS CLOSED SECURELY AROUND THE CABLE!
Connect the clamp wire to the terminals inside SOLARIMMERSION IV. If the sensor clip cable is not
long enough it can be extended up to 50m but this must be done using a double twisted pair cable
in order to stop any possible interference and a firm connection to the original cable is required.
Try to keep the extension cable as short as possible, as the signal strength from the sensor is very
low.
