Step 3: Connecting cables to Solar voltage regulator
(If required)
3.1 Position the solar voltage regulator as close as possible to the battery (must be a dry location)
3.2 Measure the distance between your battery terminals and the solar voltage regulator.
3.3 Cut the measured distance from the end of the cable, allowing some extra for slack.
3.4 Prepare as described in 2.2 the end of the cable from the in-line connector (if fitted) and attach to the
two terminals (G) on the solar voltage regulator.
3.5 Take one end of the remaining cable, prepare as above and attach to the centre terminals (H) on the
solar voltage regulator by using the same procedute as described in 1.5.
Note: Red = positive (+), black = negative (–)
Step 4: Fitting the fuse
4.1 Strip back the black outer insulation of the cable 20cm.
4.2 Cut the red cable at the halfway point and strip 5mm of the red insulation from bogh the cut ends.
Twist the bare wire ends tightly. Fit into the screw terminals (J) on each of the fuse holder pieces.
Step 5: Connecting the cable to your battery
5.1 Strip the red and black insulation (3cm) from te inner cable ends. Attach the cable to crocodile clips by
following the same procedure as described in 1.5.
5.2 Alternatively, for a more permanent connection to the battery, strip red and black insulation (6cm) from
the inner cable ends, twist the bare wire and wrap around the battery terminals and fix into position
using your battery clamps. Some clamps have connection screws fitted, in which case, if the supplied
ring terminals have been crimped onto the wire ends, simply attach using your battery clamp screws.
5.3 When connecting to a battery always observe correct polarity.

Options
Connecting an inverter into the system
7.1 Should you require your solar system to power 240v appliances, you will need to connect an inverter. Select an inverter power (measured in
watts) that is most appropriate for the power of your appliances (also measured in watts). The inverter will be ideally positioned reasonably close
to the battery. Most inverters come with pre-fixed cable so fix the loose end directly onto the battery terminals (positive to positive / negative to
negative) - contact 01684 774000 for more information.
Connecting two or more solar panels together
8.1 Should you wish to increase the power and make a solar array or increase the voltage (to produce 24volt instead of 12 volt) this can easily be
achieved. Please contact Solar Technology on 01684 774000 and request a copy of our “Creating a Solar Array” technical bulletin, which can
also be found in the ‘file download’ section at www.solartechnology.co.uk.
Adding a second battery
9.1 If a second battery is used, it can be connected to the Charge Controller, using terminals I (Fig. 3), by means of an additional piece of 2-core,
1mm cable (not supplied). As in step 4.6 above, attach the other cable to the second battery, not forgetting to add a fuse on the positive line as
descibed in step 5 above. Power from the Charge Controller will be diverted to the second battery only when the primary battery is fully charged.

Step 6: Additional information for fitting a MH kit
6.1 Attach the aluminium fitting brackets or premium profile (if PB kit has been selected) to the side of the panel using the supplied stainless steel
screws, ensuring the brackets are flush with the top of the panel frame (thereby leaving a gap between the bottom of the panel frame and
the roof).
6.2 Place the panel on the roof position where it is to be fixed and draw a pencil line around the footprint of the brackets or premium profile
(if PB kit has been selected). Ideally the panel should be fixed above the cable entry hole.
6.3 Clean the area on your motorhome, caravan or boat where each bracket or premium profile (if PB kit has been selected) and the cable feed
gland is to be fixed with spirit, and make sure the area is clean, oil free and dry.
6.4 Insert the cable trailing from the solar panel junction box into the cable feed gland, ensuring the locking nut is loose, and then into the entry
hole on the roof. Using the provided Sika Flex, now bond the cable feed gland into position.
6.5 Apply the Sika Flex (around a 6mm thickness of Sika Flex is ideal) to the edge of each bracket or premium profile (if PB kit has been selected)
and then, possibly with assistance, turn the panel so that the solar cells are facing upwards and bond the panel to the roof, positioning the
brackets in the pencil lines previously marked.
6.6 Once the cable has been pulled through the cable feed gland, the gland nut should be tightened to affect a water tight seal.
6.7 Now the cable can be channelled into the roof lining or into trunking/capping or similar and down to the battery. Finally, go to Steps 3, 4 and 5
to complete the installation.
NOTE – Sika Flex requires 24 hours to properly cure. We would therefore recommend that the motorhome, caravan or boat is not moved
during this period.
