7 Instruction manual for the kit
This Photonic Universe 20A MPPT solar charging kit set is suitable for 180W – 260W solar panels with the
maximum power voltage between 30V and 100V and the open circuit voltage up to 100V.
The kit is designed for charging either one battery, or a battery bank connected in parallel for 12V ("+" to
"+" to form a common positive, "-" to "-" to form a common negative) or a 24V battery bank (two 12V
batteries connected in series "+" to "-"). For the purposes of this instruction manual, when we refer to a
"battery", we will either mean a single 12V battery, or a 12V/24V bank of several batteries.

Electrical installation of the solar kit

IMPORTANT: Please follow the order of installation carefully. Changing this order may result in
false readings, incorrect wiring or damage to your equipment.
1. Before you install the solar kit, please make sure that your battery is charged so that it generates at
least 9V or more for a 12V system. For a 24V system, the voltage must be greater than 18V. This is
required to enable the solar charge controller to work. If your battery is fully discharged, please
charge it by other means first, otherwise the controller will not start.
2. Connect the terminals of your battery to the solar controller battery terminals using the 6.0mm
core battery cable included with the set. If the length of 5m cable is not enough, please use extra
cable with an appropriate cross-section (6.0mm
end, use bare wires and fix them in screw terminals. On the battery end, use connectors suitable for
your battery (ring terminals, battery clamps for studs etc).
Note: when you connect the battery to the solar controller, it will switch ON the LCD display. This
means the controller has detected the battery and you can proceed with the installation. Do not
continue if the LCD display on the controller does not turn ON, and follow the necessary steps in the
Troubleshooting section of this manual.
3. When connecting the solar panel to the charge controller, we recommend feeding the extension solar
cable through the waterproof cable entry gland from outside-to-inside, and then attaching the solar
panel cable via the MC4 connectors so that the MC4 connection point is outside of the cable gland.
Make sure that the polarity of each cable is correct and attach additional polarity tags or coloured tape
on the loose end of the solar extension cable. Please ignore polarity signs on MC4 cable
connectors and only follow polarity labels on the solar panel cables. If the solar panel is
