Full List of Solar System Wiring & Installation Circuit Diagram – 12V and 24V

I spent all day to walk around everywhere  on the internet to find a circuit diagram for my home 12V Solar system. But it’s so hard to find out exactly what I want, and I think you too. So I am here to provide you list of circuit diagram for the various sized systems, including 12V and 24V. Wiring diagrams include:

#1: A Micro System – 12 Volt, 20-40 Watt, 18 Amp-Hr Systems


The system wiring diagram below is a copy of the door wiring diagram for one of three systems of the Micro size. A pole mounted polycarbonate enclosure houses the solar controller, terminal and fuse blocks and factory wired components. Wires shown in solid lines are factory wired, dashed to be wired and connected in the field, and dotted (load) to provided by and connected by the customer. The solar module is also pole mounted, above the enclosure.

#2: A Small System – 12 Volt, 10 -40 Watt 36 Amp-Hr Systems


Image below is a copy of the door wiring diagram for one of four Small systems. A white powder coated aluminium enclosure houses the solar controller and associated wiring. The enclosure is pole mounted, typically on the same pole below the solar modules. Wires shown in solid lines are factory wired, dashed to be wired and connected in the field, and dotted (load) to provided by and connected by the customer.

#3: Large System – 12 Volt 85 to 130 Watt 198 Amp-Hr Systems


A copy of the door wiring diagram for a Large system is shown. This system houses a single solar controller module, but requires two batteries connected in parallel to achieve the required amp-hour rating. A white powder coated aluminium enclosure houses the solar controller and associated wiring.
The enclosure is pole mounted, typically on the same pole below the solar modules. Wires shown in solid lines are factory wired, dashed to be wired and connected in the field, and dotted (load) to provided by and connected by the customer.

#4: A Larger 12 Volt 170 Watt, 265 Amp-Hr System


Diagram below is a copy of the door wiring diagram for one of the larger systems containing one battery with two solar modules connected in parallel to give the required power needed for battery charging. A white powder coated aluminium enclosure houses the solar controller and associated wiring. The enclosure is pole mounted, typically on the same pole below the solar modules. Wires shown in solid lines are factory wired, dashed to be wired and connected in the field, and dotted (load) to provided by and connected by the customer.

#5: A large System – 12 Volt 260 – 390 Watt 420 – 530Amp-Hr Systems


The door wiring diagram copy for the system shown in image below shows a system with multiple batteries and solar modules. A white powder coated aluminium enclosure houses the solar controller and associated wiring. The enclosure is pole mounted, typically on the same pole below the solar modules. Wires shown in solid lines are factory wired, dashed to be wired and connected in the field, and dotted (load) to provided by and connected by the customer.

#6: A 24 Volt System – 24 Volt 80 -130 Watt 36Amp-Hr Systems


Image below is a copy of the door wiring diagram for a 25 volt system. Note the parallel wiring of the 12 volt solar modules and 12 volt batteries to yield the necessary 24 volts for the solar controller. A white powder coated aluminium enclosure houses the solar controller and associated wiring. The enclosure is pole mounted, typically on the same pole below the solar modules. Wires shown in solid lines are factory wired, dashed to be wired and connected in the field, and dotted (load) to provided by and connected by the customer.

#7: Extra Large System – 24 Volt 350- 525 Watt 210 – 265Amp-Hr Systems


This is a copy of the door wiring diagram for an extra large system showing three 24 volt 175 Watt Solar Modules connected in parallel to provide the required power rating, and two 12 volt batteries connected in series to yield the required 24 volts. A white powder coated aluminium enclosure houses the solar controller and associated wiring. The enclosure is pole mounted, typically on the same pole below the solar modules. Wires shown in solid lines are factory wired, dashed to be wired and connected in the field, and dotted (load) to provided by and connected by the customer.
