The Apex SGS is the heart of a water heating system –
intelligently heating water in a standard electric geyser
from the sun’s energy. The SGS controls and manages
the system, providing historical and up to the minute
information on status and performance via its web app.
Through considering factors beyond just temperature,
the system makes intelligent decisions – ensuring that
minimal grid power is used. When both grid and solar
power sources are available, the system favours solar
as its power source, ensuring maximum savings.

To install the SGS, follow these steps:
Not directly below the Geyser where it may be splashed by
any geyser leak event or in the case of maintenance work.
Begin by making sure that the AC supply is fully
isolated, either at the main breaker, RCD or
dedicated isolation device. Then ensure that the
DC PV supply is also fully isolated. Ensure that
supplies are locked out to prevent accidental
reconnection, as necessary.
5.1 SAFETY AND ISOLATION 5.3 ELECTRICAL INSTALLATION
As the SGS is installed into a building’s electrical
infrastructure and has both AC and DC power
supplies, it is necessary to ensure that the
installation area is secured and safe before
beginning the installation.
The SGS may not be mounted horizontally or at
an oblique angle. It must be mounted with the
terminal chamber at the boom of the font cover
(ie: correctly rotated)

Solar Geyser System Manual 10
Remove the power cable feeding the existing geyser from
the terminations inside the geyser’s terminal chamber or
local isolator at the geyser, according to local regulations.
This cable then becomes the power supply to the SGS
terminals on the PC board. Ensure that the Live, Neutral
and Earth conductors are all connected securely and
according to the labels.
Run a new cable of suitable cross section from the 2
terminal of the SGS’s PC board to the location where the
chamber or the local isolator, depending on local
regulations. Ensure that the Live, Neutral and Earth
conductors are all connected securely and according
to the labels on the Apex SGS and the Geyser.
Connect a supply from a suitably sized dedicated circuit
breaker in the distribution board with a suitable cross
section cable to the SGS. This cable is the power supply to
the SGS and is terminated at the “L”, “N” and earth (AC
Neutral and Earth conductors are all connected securely
and according to the labels on the PC board.
Run a cable of suitable cross section from the terminals
SGS’s PC board to the Geyser’s terminal chamber or the
local isolator, depending on local regulations. Ensure that
the Live, Neutral and Earth conductors are all connected
securely and according to the labels on the SGS and
the Geyser.
Ensure that the Geyser is fully earthed, according
to local regulations.
Ensure that the geyser’s thermostat is
correctly connected into the circuit, as per the
manufacturer’s instructions. This is an important
safety device and may not be omied.

The DC supply shall be isolatable locally at the SGS for
both safety and convenience. This can be done either with
a suitably rated double-pole DC circuit breaker or isolator,
with a rating of at least 250V and 16A DC.
The Apex SGS should only be connected to a single, series
more than 15A. 2 parallel strings of panels are only allowed
when they are of the “High voltage” type, with a short
circuit current of less than 7A per string.
Before connection, check the polarity of the incoming PV
supply with a suitable DC test instrument to ensure that
the Apex SGS is not exposed to reverse polarity. Then,
with the PV Array exposed to full sunlight, check that the
PV voltage is within the allowable limits of 120 – 230V DC.
Ensure that the DC cables are correctly terminated into
original Staubli MC4 connectors only.
Now connect the DC PV power supply to the MC4
Note that if a DC breaker is used in this location, it
is not possible for it to trip on over-current events,
since the PV string cannot generate enough current
beyond its operational curve to do so.
Ensure that the SGS is protected with Surge
Protection Devices (SPD’s) on both the AC and
DC supply interfaces.

The SGS is supplied with a temperature sensor designed
the existing thermostat.
The probe is made from industrial grade K-type
thermocouple wire with our patented, proprietary
temperature sensor. It consists of k-type wire leading
-
ducting heat to the junction.
Installing the collar is an easy process. Start at the geyser
and work towards the SGS. With the power to the geyser
feed the copper strip into the thermostat pocket, all the
way up to the collar.
Then feed the geyser thermostat through the centre of the
probe collar into the geyser pocket and push it all the way
in until the current carrying contacts of the thermostat
mate with the geyser.
Be careful not to damage the probe or its insulation as
you push the thermostat into place. It is important that
the temperature probe is correctly installed so that it
cannot be accidentally removed, thus causing an incorrect
temperature reading.
From there, the probe wire can be fed to the SGS,
avoiding other cables as far as possible to minimise
electrical noise being induced.
Set the geyser thermostat to maximum (usually 70
and the thermostat now only acts as a fail safe.
The SGS can heat water to scalding temperatures.
Depending on the installation, a mixing valve may
be required to regulate the temperature to safe
levels at the points of use. Consult local regulations.

Now connect the other end of the probe’s cable to the
SGS’s PCB as shown in Figure 7.
The supplied temperature probe is 10m long.
Longer (or shorter) lengths can be manufactured
to order but need to be carefully routed to avoid
electrical noise being induced. Always take care
how you route the cable away from other cables
and electrical devices. Should spurious readings
occur, check your routing and move it away from
all other cables. In general, the shorter the cable
the beer the reliability of the reading.
Note that if the SGS does not power up from the
PV interface alone it is possible that the PV supply
polarity is not correct or that there is insuicient
power available on the panels.
Begin with the geyser switched on at its local isolator.
Since the SGS can be run on either power supply, its
power-up sequence is not critical. However, powering

A generator may also be used on the input, in which case
the SGS will behave as described in the On-grid use case.
The SGS is designed to assume temperature control
of the geyser to which it is connected and operates
autonomously. However, the original thermal cut-out
device shall remain in place to ensure that, in the
unlikely event of a failure of the SGS, the system will
remain below dangerous temperature levels.
To do this, set the original mechanical thermostat to the
local regulations which may determine the maximum
allowable temperatures. Fit a mixing valve to ensure
that the water is a safe temperature at the point of use.

If this LED illuminates, it is likely that the probe is
damaged. Remove the probe and inspect it for insulation
damage and, if necessary, replace it.
It is designed to detect current leakage on the output
above 30mA, and it will shut the Apex SGS down into a
safe state. In such circumstances, the DC array, geyser
and AC supply should be treated with great care and
the fault located and corrected urgently.
