Highligts
Waterproof with breather to equalise internal and external pressure to prevent water ingress
Adjusts charge rate to protect alternator if vehicle voltage drops too low and turns ON warning LED
Features
Waterproof with special breather membrane that equalises internal and external pressure thus preventing
water getting in the unit as a result of temperature fluctuations
Can be mounted external to vehicle and in engine compartment
Auto switch over from Solar Panel MPPT mode to Car mode when alternator voltage is detected
Will automatically charge vehicle main battery when in Solar Panel mode and second battery is fully charged
High current dual purpose 20A 12V DC to DC battery charger
Suitable for deep cycle and cranking lead acid batteries of 70Ah and higher battery capacities
Eliminates dual battery switch
Will not flatten vehicle battery
Compensates for voltage drops over supply wires
Dual purpose lead acid battery charger (charges from car or solar panel without having to re-connect car
or solar panel)
Integrated 300W MPPT solar charger
Integrated alternator overload protection
Integrated bypass circuit automatically connects loads directly to alternator when charger operates thus
making full 20A available to charge battery.
Three state charger optimises charging (bulk, constant voltage and trickle charging)
Two colour charge indicator LED shows charging and charge completion status
Integrated battery temperature compensation to prolong battery life
Red fault indicator LED lights up if vehicle wiring does not meet minimum resistance requirements
Noiseless with no cooling fans
Integrated over temperature protection
Short circuit and reverse battery protection on all inputs and outputs
Sturdy powder coated die cast aluminium enclosure
Easy installation with high quality screw type wire connections
LED indicators
Charge LED
Amber when fast charging
Green when trickle charging
Fault LED
Solid RED if alternator protection is enabled (turns ON if vehicle voltage is too low due to faulty
wiring or alternator)
Flashing RED 3 seconds ON and 3 seconds OFF if battery temperature probe is faulty
Flashing RED 1 seconds ON and 1 seconds OFF if solar panel voltage is too high
Internal automotive blade fuses
25A on Car input
25A on battery input
15A on load output
Fuses can be replaced by removing the 4x black screws in the corners of the bottom cover.
Use knife to break the silicon seal and replace with fresh silicon before fitting the bottom cover.
Connections
+Car - Connect to car battery positive terminal using 10mm2  wire
+SP - Connect 12V Solar Panel positive using 4mm2  wire
GND - Connect to battery to be charged negative terminal using 6mm2  wire
+Bat - Connect to battery to be charged positive terminal using 6mm2  wire
+Load - Connect to load (fridge etc) positive input using 6mm2  wire
Connect negative return wires directly to battery negative terminal (10mm2 -Car, 4mm2 -Solar Panel, 6mm2 -Loads)

Breather notes
Traditional sealed waterproof enclosures use an o-ring to seal the product but this method is not suitable
for operation in extreme environments where the product is subjected to large temperature fluctuations and water as found in engine compartments. In engine compartments the ambient temperature can easily reach 50°C to 60°C. If the engine mounted product is now suddenly cooled as a result of splashed water or wading the product cools down quickly and the internal pressure drops and water is sucked past the o-ring and becomes trapped inside the product. The only way to prevent the water ingress is to provide the unit with a breather made of a porous plastic membrane with hole sizes small enough to prevent water molecules passing through the membrane but large enough to allow air to freely pass through the membrane. The membrane thus equalises the internal and external pressure preventing water being sucked into the enclosure when subjected to cooling when exposed to water.

Warning
Do not submerse in water
Do not short load output to ground
Ensure Car, Soar panel and Battery polarity is correct
