Layout & Configuration
1. Figure out how many panels you will need, and the amount of panels you can actually fit on the space you will be installing them.
2. Measure how much wire you will need, by measuring where and how the wire will run to the charge controller than to the batteries.
3. Batteries to Inverter (Inverter is typically very close to batteries because of the amount of Amperage needed to run them.)

Planning & Starting The Installation
Resettable Fuse Breaker
(Ensures line protection
incase of any dead shorts)
Must be in the positive line
and as close to the battery
terminal as possible.

37 Volt Solar Panels 37 Volt Solar Panels
This diagram shows two 37 Volt Solar Panels connected in series which increases the voltage to 74 Volts.
The MPPT charge controller will match the battery voltage and convert the rest into Amperage allowing it to use
up to 97 % of the solar panel power. The efficiency can be up to 30% more than regular PWM charge controller.

12V-DC Inverter Terminals
Battery/Protection Fuse (from battery to inverter)
(Fuse needs to be as close to battery terminal as possible)
Fuse Amp size is based on inverter Wattage.
(Total Watts divided by Volts = “Fuse Amp Size”)
Some Examples:
A: 1500 Watt Inverter = 125A Fuse
B: 2500 Watt Inverter = 220A Fuse
C: 3500 Watt Inverter = 300A Fuse
D: 5000 Watt Inverter = 425A Fuse
12 Volt Inverters
Inverter Installation Diagram
- Batteries fasten to inverter terminals using 3/8 connectors normally. (Terminal size is based on inverter & Battery Type)
- Cable thickness is determined by Length Volts and Amperage. Good Practice to use 00AWG Wire no longer than 4 feet.
- Any wires/cables coming from battery power source need to have a protective fuse with the positive line.

Solar Panel Mounting
(12" Mounting kit installation example)
STEP 1.
Fasten Z-brackets to solar panel frame ( Depending on the solar panel
you might have to drill another hole in the panel frame so that the
z-brackets can be fastened properly to panel.
STEP 2.
Place solar panels into its position.
Layout & Configuration
- Install mounting on solar panel frame (12" mounting kit comes with Z-Bracket, nuts and bolts to fasten directly onto solar panel)
- Find a spot that you can run down your cable easily (ventilation or drill a hole through the roof top)
- Place solar panel as close to your wire drop down spot as you can.
- Refer to below diagram for installation.

Nuts & Bolts to Solar Panel
Fastened Z-Bracket
(8) Stainless steel
nuts & bolts fastened
to solar panel using
Z-Bracket.
STEP 3.
Connect your MC4 cable to panels and fish down your wire to the
charge controller. Cut and splice the cable once you reach charge
controller. Now wire the spliced cable into solar panel connections
labelled solar panel. Take the left over of the wire with the 3/8 lugs
and do the same but wire it into battery terminals.
Wire can be dropped down vents
or drill a hole through the roof.
(Caulk the hole liberally)
STEP 5.
Connect Charge Controller (Use charge controller manual)
STEP 4.
Drill Pilot Holes for 12" z-brackets into roof. (Use 9/64 Drill Bit Size)
In order to keep pilot hole lined up lift one side at a time and liberally
caulk the pilot holes with QUAD, and under belly of the two z-brackets.
Do the same to other side and than lag bolt the panels down onto roof.
